Title: Ultrasonic delay line
Inventor: NARITA KATSUMI
IPC: H03H9/36
Filed: 1984-05-21
Abstract: PURPOSE:To improve the piezoelectric conversion efficiency by attaching a voltage converting element for both input and output to one side surface of a delay medium and processing the sound wave reflecting surface of the delay medium into a curved surface where the incident route is equal to the reflection route. CONSTITUTION:A sound wave reflecting surface 7a of a glass plate 7 serving as a delay medium for sound wave is processed to be a part of a spherical surface of a radius R centering on a middle point O of a sound wave radiation surface of a piezo-magnetic plate 3. As a result, a sound wave component 8a which is transmitted toward a main axis and sound components 8b and 8c transmitted in the direction shifted from the main axis due to the directivity are reflected by the surface 7a and return to the center O of the plate 3, i.e. the center of the surface 7a through a reflection route equal to an incident route. Thus, a loss of sound waves is eliminated and the piezoelectric conversion efficiency is improved.

Filed: 1995-04-26
Abstract: PURPOSE: To provide a jelly-filled cable which allows the continuous execution of a stage for forcibly injecting the jelly and is provided with a part not filled with the jelly at the desired point of a cable terminal at the time of producing the cable. CONSTITUTION: A through-hole for injecting the jelly is formed at a first coating layer 2 of a cable body exclusive of the cable terminal of this jelly filled cable. On the other hand, the through-hole for injecting the jelly is not formed at the first coating layer 2 at the cable terminal. Then, the jelly 4 may not be injected into the first coating layer 2 at the cable terminal at the time of forcibly injecting the jelly 4 into the first coating layer 2. The continuous execution of the stage for forcibly injecting the jelly 4 is, therefore, made possible at the time of producing the jelly filled cable.

Title: Optical fiber
Inventor: SATOU MAKOTO
IPC: G02B6/10
Filed: 1983-06-10
Abstract: PURPOSE:To take out effectively light emerging from an infrared-ray transmitting optical fiber having a chalcogenide glass core as convergeable light by providing the shape of a convex lens to the light emergent end of the fiber. CONSTITUTION:An optical fiber having a chalcogenide glass core is manufactured by a conventional method, and one end of the fiber is cut perpendicularly. The measured transmission loss (alpha) of this fiber is 0.3dB/m (lambda=10.6mum). When the perpendicular end is shaped as shown by the figure after melting by electric discharge in inert gaseous Ar, the loss (alpha) is reduced to 0.2dB/m. When the length of the perpendicularly cut optical fiber is increased from 5m to 10m, the measured loss is reduced. As a result, it is found that the reduction of the loss after the shaping is based on the reflection loss at the emergent end.

Title: Signal recording or reproducing device
Inventor: SUZUKI KATSUSHI
IPC: G11B15/10
Filed: 1991-05-08
Abstract: PURPOSE:To achieve mode switching with an extremely small number of operation keys and enable operability to be enhanced by allowing a function of a plurality of operation members to be different depending on which mode out of a plurality of modes a device is in. CONSTITUTION:Each mode of stop, record pause, reproduction, fast-forward, rewind, fast-forward search, rewind search, still reproduction, and slow reproduction is given to operation keys K1-K5 in the order of mode shift functions with a higher probability. Then, when, for example, the operation key K1 is operated in stop mode, a system control circuit 31 sets the device to record pause mode. On the other hand, when it is operated in record pause mode the system control circuit 31 returns the device to the record pause mode. This configuration achieves mode switching with an extremely small number of operation keys and a function which is used more frequently always with a same operation key thus enabling operability to be improved.

Title: Seat device for vehicle
Inventor: ICHIKAWA KENJI
IPC: B60N2/14
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To improve the ascending/descending property on/from a vehicle by providing a height regulation mechanism part capable of changing the height of a seating surface of a seat during the turn on a rotary device. SOLUTION: A height regulation mechanism part 20 of screw type by bolt-nut structure comprises screw parts 14, 16 of cylindrical parts 15, 17. The movement in the height direction by the height regulation mechanism part 20 is determined by the turn of a seat and the screw pitch of the screw parts 14, 16. When the turn of the seat is in the angular range of approximately 90 deg. and the movement in the height direction is insufficient by one row of screws, the movement is freely set by increasing the number of row of screws such as two rows and three rows, and by the regulation of the screw pitch. A turning device provided with the screw type height regulation mechanism part 20 can change the direction of the seat and the height of the seating surface in an interlocking manner with each other, and further improves the ascending/descending property on/from the vehicle.

Patent JP-H0798884-A (JP)
Title: Optical memory
Inventor: YONEKUBO MASATOSHI
IPC: G11B7/09
Filed: 1991-05-08
Abstract: PURPOSE:To reduce the optical beam shift amount generated by the rotation of a galvano mirror and to obtain the stable operation by using the afocal optical system which does not perform the collection and distribution of the incident light. CONSTITUTION:In afocal optical system, a convex lens is used as a group optical system 102 and a convex lens is used as a group optical system 103. The optical distance between the optical systems 102 and 103 is essentially equal to the sum of the focal distance f1 of the optical system 102 and the focal distance f2 of the optical system 103. Thus, when the light beam making the angle theta1 against an optical axis 101 is made incident on the optical system 102, the light is collected temporarily to the focal distance f1 and reaches the optical system 103. The beam 104 emitted from the system 103 is emitted with the angle theta2 against the light axis 101 and is crossed with the optical axis 101 at the position of the distance (d). Thus, when the objective lens 105 is placed at the position where the beam 104 is crossed with the optical axis 101, the light beam shift does not occur even when the angle theta1 which is made incident on the system 102 due to the inclination of a galvano mirror 206 is changed.

IPC: G11C17/00
Filed: 1984-05-22
Abstract: PURPOSE:To improve the operating speed of a memory by constituting the titled circuit so that a voltage of a power supply is applied as it is without causing a voltage drop at read as conventional circuits thereby quickening the establishment of a potential of an address line. CONSTITUTION:A level of an input terminal 30 is ''L'' at read, then the level of nodes 31, 33 go to ''L'', pMOSTQ37, 42 are turned on, nMOSTQ38, Q43 are turned off, the level of nodes 32, 34 go to a voltage VPP of the 2nd power supply VPP, the pMOSTQ44 is turned off and the nMOSTQ39 is turned on. Since the voltage of the node 32 reaches the voltage VPP(=VDD+VTN), the voltage VDD of the 1st power supply VDD is obtained at an output terminal 35 without being effected by the voltage drop of the threshold voltage VTN of the nMOSTQ39. Thus, the establishment of potential of an address line of an EPROM is quickened at read so as to improve the operating speed of the EPROM.

Abstract: PURPOSE:To reduce the number of parts to a large extent and to enhance the reliability in the detection of the passage of a metal object, by providing an oscillation circuit, which has a resonance circuit including a metal object passage detection coil, to a positive feedback circuit. CONSTITUTION:An oscillation circuit 4 having a resonance circuit including a metal object passage detection coil 4a is provided to a positive feedback circuit and predetermined bias voltage is applied by the feedback resistor 13 of a bias circuit. The output of the circuit 4 is detected by a detection means having a pair of transistors 24, 25 constituted in differential connection and the condenser 29 arranged in the common emitter side of said transistors 24, 25. When a metal object is passing through the coil 4a, Q of the circuit 4 becomes low and the impedance thereof is low and, therefore, the circuit 4 does not oscillate. Hereupon, a transistor 36 is brought to an ON-state while a transistor 38 to an OFF- state and output of ''1'' is obtained at an output terminal 39. When the metal object is separated from the coil 4a, the circuit 4 oscillates and the transistor 36 is brought to an OFF-state while the transistor 38 to an ON-state and output of ''0'' is obtained at the terminal.

Title: Control device for moving rest in machine tool
Inventor: SHIBATA SOICHI
IPC: B23Q15/013
Filed: 1989-04-24
Abstract: PURPOSE:To prevent generation of a machining error, caused by yawing of a moving rest, by controlling a moving amount, being based on a mean value of two detection values by two laser beams, and applied voltage to a piezoelectric element being based on a difference signal between the detection values. CONSTITUTION:When yawing is generated in a moving a moving rest 1, because a difference is generated between optical path lengths of two laser beams Ll, Lr projected to the moving rest 1 or a supporting bed 31, a difference is generat ed between two detection values of a laser beam length measuring machine. Then applying voltage of value corresponding to this difference to piezoelectric elements 8l, 8r, a torsional deflection member 7 is given the torsional deforma tion of direction and amount negating the yawing. Thus even when the moving rest 1 in its guide or drive part performs yawing, a tool 32 or the like mounted thereon performs no yawing. While because also a moving amount of the moving rest 1 is controlled by a mean value of that detected by the two laser beams Ll, Lr, a moving position of a contact point of the tool 32 with a workpiece can be accurately maintained.
