Title: Improvements in or relating to electrical musical instruments
IPC: E04B1/41
Filed: 1931-01-10
Abstract: 365,309. Electrical musical instruments ; ; thermionic valves transformers ; inductances. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of Hitchcock, R. C. ; 530, Roxbury Road, Wilkinsburg, Pennsylvania, U.S.A.) Jan. 10, 1931, No. 895. Convention date, Jan. 20, 1930. [Class 88 (ii).] An electrical musical instrument employs a separate oscillating thermionic valve for the fundamental and each important harmonic of each note whereby timbre may be varied ; the treble and bass currents are led to separate loud speakers, there being a variable division between the treble and bass notes ; and means are provided for tuning the valves, for preventing " key-thump," for regulating volume, for producing tremolo, and for adjusting the character of the sound-output from the loud speakers. The instrument shown has a scale of forty notes in four groups 1 .. 4 of ten notes each, each note consisting of a fundamental emitted by a valve 5 and harmonics from valves 6, 7, 8, and being controlled by a key 23. " Key-thump " is prevented by a choke 24 and large condenser 25. The valves are fine tuned by the means shown in Fig. 3, the input and output coils 10, 11 of a valve being mounted on the central limb of an E-shaped laminated magnet 14, a similar magnet 13 pressed by a spring 20 being caused to approach the magnet 14 by screws 21. Timbre is varied by varying the points on resistors 26 from which connection is made through condensers 28 to the output lead 27. The condensers 28 prevent interaction between the valves pertaining to one note. It is stated that the apparent loudness of certain harmonics relative to the fundamental increases if the note is held, and in these circumstances means such as clockwork, automatic biasing-means, or means automatically varying the effective points on the resistors 26, may be provided for reducing the amplitude of the harmonics. All the fundamentals or corresponding harmonics may be cut out by switches 30, of which corresponding ones may be coupled for simultaneous actuation. The output leads 32 .. 35 from the groups 1 .. 4 connect through amplifiers 55 to treble and bass loud-speakers 62. A switch comprising two insulated plates 42, 43, connected to the respective loud-speaker circuits, determines the allocation of the groups to the loud-speakers. The two loud-speaker circuits may be connected by a switch 74. Shunt condensers 63 under the performer's control vary the proportion of high to low frequencies in the loud-speaker output. Potentiometers 45, 47 provide a first volume-control, while further volume-control for crescendo and accentuation is obtained by a variable shunt-resistance 59 operated by a pedal 61. Tremolo is obtained by rocking a magnet 66, by means of a crank 68 and motor 71, near a magnet 65 carrying a coil 53 in the circuit. The coil 53 may be cut out by a switch 72, being replaced by a coil 73. The amplifiers may be omitted and the tonefrequencies directly impressed on a broadcasting apparatus.

Title: Bi-compliant rotor stepper motor for an actuator in disc drives
Inventor: GHOSE SANJOY
IPC: G11B5/55
Filed: 1992-07-09
Abstract: The disclosure relates to a technique for effectively floating the rotor (37) of a disc drive motor, thereby permitting small motions in the axial (non-critical) direction while maintaining significant stiffness of the radial (critical) direction. This is achieved by providing an electromagnetic actuator inluding a stepper motor having a housing, a stator located within the housing, and a rotor (37) positionable relative to the stator driving a motor shaft to wind and unwind a band (14) and thereby position the carriage. The drive shaft (12) passes through ball bearings (30) which support the shaft for rotation. The ball bearings themselves fit within an annular end bell portion (39) of the motor housing which defines a channel for the bearing. An injected elastomer (33) forms a tight-fitting ring between the bearings and the internal wall of the end bell (39), thereby radially supporting the outer race of the bearing. Preload springs (36) are then installed on both sides of the rotor between the internal end walls of the end bells and both outer races of the bearing. the installation of these springs effectively floats the rotor to allow some distortion of movement of the rotor in the axial direction, while minimizing or eliminating the radial deflection components.

Title: Coin checking apparatus
Inventor: ROBERTS MARKS
IPC: G07D5/00
Filed: 1993-06-03
Abstract: The arrival of a coin in a coin checking apparatus is detected by arranging for the coin to hit a member (16). The vibration caused by the impact causes a piezoelectric element (36,36a) to give a transient output signal which is used to switch on electronic circuitry of the coin checking apparatus. The circuitry is normally switched off and thus over a period of time the average power consumption of the coin checking apparatus is low so that it can be satisfactorily run from a battery.

Title: X-ray generator
Inventor: AMAMIYA MITSUAKI
IPC: H05G1/02
Filed: 1987-01-06
Abstract: PURPOSE:To extend the life and easily generate X-rays having the desired wavelength by forming the wall faces of a capillary with a dielectric sheet and renewing the wall faces in response to the consumption of the wall faces. CONSTITUTION:A capillary 2 is constituted of six triangle pole-shaped insulators 8 and a dielectric sheet 9 covering the insulators so that the dielectric sheet 9 can be renewed. When a capacitor Cd is charged and the sufficiently large voltage is applied to the insulators 8, the dielectric sheet 9 covering the insulators 8 and a material 10 are evaporated by the creeping discharge of the capillary 2 to generate plasma 8. In this case, when an electron beam is radiated from a cathode 6 to the plasma 5, x-rays 7 in the wavelength area corresponding to the material 10 are generated. However, part of the surface of the dielectric sheet 9 facing the capillary 2 generates plasma by the creeping discharge, thus the sheet is made thin after X-rays are generated. Therefore, the dielectric sheet 9 is moved so that new faces not generating plasma encircle the capillary 2.

Filed: 1988-01-06
Abstract: PURPOSE:To prevent a substrate from being damaged by implanting an impurity to be used to isolate a p-n junction before the substrate is ground and polished after an epitaxial process. CONSTITUTION:The main surface 100 of an Si single-crystal substrate 1 of an n-type conductivity type is oxidized; an oxide film 2 is formed; the oxide film is removed selectively. Then, V-shaped isolation grooves 3 are formed by a selective etching operation by making use of the remaining oxide film as a mask. Then, an oxidation operation is executed again; an oxide film 4 is formed; one part of the oxide film 4 constituting vertical-type single-crystal regions 51, 52 is removed; then, Si is grown by a vapor epitaxial growth operation; single- crystal Si 51, 52 are grown in parts where the oxide film 4 has been removed; polycrystalline Si 7 is grown in parts where the oxide film has been left. Then, a p-n isolation is executed by diffusion of aluminum; while Al inside the polycrystalline Si 7 is diffused a little in the single-crystal regions, it reaches the oxide film for isolation use; in addition, Al is diffused from the polycrystalline region to the single-crystal regions; a junction for p-n isolation use is formed; the two insulated and isolated vertical-type single-crystal regions and a single- crystal island which has been insulated and isolated by the oxide film are united. By this setup, a p-n junction for isolation use can be executed in a state that the substrate is thick; accordingly, a yield is enhanced.

Filed: 1989-01-05
Abstract: PURPOSE:To select an instruction optimum to the flow of instructions of users by forming the different instruction hierarchies that can execute the same instruction and selecting one of these hierarchies to facilitate the input operations of instructions. CONSTITUTION:The LINE instructions a1-a3 to instruct to plot straight lines on a screen belong to a higher rank hierarchy X, and the DATA instructions b1-b3 to instruct to process data belong to a higher rank hierarchy. These instructions of both hierarchies are sorted in terms of functions into the instructions a1 and b1 as the input PUT instructions, the instructions a2 and b2 as the movement MOVE instructions, and the instructions a3 and b3 as the deletion DEL instructions. Furthermore, a higher rank hierarchy Z1 is prepared in addition to both hierarchies X and Y for selection the PUT instructions a1 and b1 since these instructions are used repetitively. Thus the repetitive and alternate input is attained for both instructions a1 and b1 with no selection of the hierarchies X and Y.

IPC: H04N5/74
Filed: 1992-01-07
Abstract: PURPOSE:To improve the light utilization efficiency and to make a color irregularity and a brightness irregularity hard to generate by arranging areas, illuminated with two pieces of luminous flux which are in the same color and equal in light quantity among pieces of luminous flux from two adjacent polarized light illuminators, in diagonal position relation. CONSTITUTION:The constitution of a polarization beam splitter 11', a work surface 11a', and a total reflecting prism 12' is symmetrical with the combination of a polarization beam splitter 11, a work surface 11a, and a total reflection prism 12 with respect to the plane of the border between the polarization beam splitter 11 and total reflection prism 12. Then the irregularity of the luminous flux projected from the polarized light illuminators becomes inconspicuous since a light area and a dark area becomes plural small divided areas. This results from the acceleration of the overlapping effect of the pieces of luminous flux since the luminous flux from the light source has a constant spread angle.

Title: Ventilation control device for floor type air-conditioning machine
Inventor: KURIYAMA KEIICHI
IPC: F24F11/02
Filed: 1986-01-07
Abstract: PURPOSE:To prevent the re-evaporation of dew water of a heat exchanger without passing ventilating air through a heat exchanger and improve comfortableness by operating only the lower fan of an indoor unit while stopping a compressor. CONSTITUTION:When an air-conditioning machine is operated and a set temperature is inputted, room temperature is inputted from a room temperature sensor into a room temperature detecting unit. In case the room temperature is higher than the set temperature, a compressor is driven by the decision of an operation control unit and an upper fan 4 as well as a lower fan 5 are rotated into arrow symbol directions. According to this operation, cool air is sent to upper and lower directions in a room. When the room temperature has become lower than the set temperature, the compressor and the upper fan 4 are stopped while the lower fan 5 is rotated to the arrow sign direction whereby air, not passed through an indoor heat exchanger 3, flows in the room. According to this method, the re-evaporation of dew water of the heat exchanger 3 may be prevented. On the other hand, cool air is mixed and the distribution of room temperature may be improved.
