IPC: G11B17/028
Filed: 1986-05-20
Abstract: PURPOSE:To press and fix a disk on a turntable by utilizing repulsion, by providing a permanent magnet, and a disk pressing means made of an elastic material protruding to the turntable side beyond the permanent magnet, at a clamper which sandwiches the disk between the turntable. CONSTITUTION:By lifting down the other end side of a clamp arm 11 on a turntable 10, a clamper 12 is attracted to a turntable 12 side by the magnetic attracting action of a permanent magnet 20. With the above movement, a disk pressing means 21 is abutted on a disk D placed on the turntable 10, and is compressed relatively by being defeated by the magnetic attracting force, there fore, the disk D is pressed on the turntable 10 with the repulsion. At such a time, so that the clamper 12 is attracted until a time when a guide hole 19a is abutted with the upper end of a center spindle 14 against the elasticity of the pressing means 21 by the magnetic attracting force of the permanent magnet 20, the compressing width of the disk pressing means 21 is dependent on the thickness of the disk D.

Filed: 1980-08-25
Abstract: PURPOSE:To decrease the total number of capacity arrays, and to reduce an area of a chip, by setting the reference voltage of a comparator to 1/2, in a successive comparison type D/A converter. CONSTITUTION:Sampling of an input signal is executed by changing over a switch 120 and a switch 101 to the side of an analog input terminal 121 and the side of 2, respectively, and subsequently, the switch 120 is changed over to the side of ground. Voltage Vx in this case becomes Vx=(VRef/2)-Vin. Subsequently, decision of MSB (uppermost bit) is executed by changing over a switch 118 to the side of a reference voltage terminal 122. Voltage Vx in this case becomes Vx=(VRef/2-Vin) +VRef/2. Accordingly, comparison reference voltage of a comparator 102 becomes VRef/2 by a resistance 131. After that, in the same way, the input signal Vin is converted to a digital value by controlling switches 117-112.

Title: Power motor provided with temperature compensation characteristic
Inventor: JIEI OTSUTOO BAIYAAZU JIYUNIA
IPC: F15B13/043
Filed: 1993-05-18
Abstract: PURPOSE: To maintain prescribed gaps of cylindrical plates in relation to an armature and to make a magnetic flux density of a permanent magnet circuit constant by providing a temperature compensator which responds to a change in the temperature of a motor and expands and contracts differentially with respect to the cylindrical plates. CONSTITUTION: An equipment 100 comprises two parts of a fluid pressure valve assembly 102 and a motor 104, and the motor 104 is a two-way electric-magnetic actuator. When the temperature of the motor 104 rises, the length of a rod 192 increases proportionally, and a ring-shaped spring 148 is compressed to make cylindrical plates 122 and 124 move toward each other. Therefore the length of each of gap 129 and 131 is reduced, in proportion to the linear extension of the rod 192. When the temperature of the motor 104 lowers, the length of the rod 192 decreases proportionally, the ring- shaped spring 148 biases the cylindrical plates 122 and 124 so as to make them at a distant from each other, in response to the contraction of the rod 192, and the prescribed length of the gaps 129 and 131 is increased. Thereby a magnetic flux density of a permanent magnet circuit is maintained to be essentially constant, even when the temperature of the motor 104 changes.

Title: Transient darlington transistor circuit
Inventor: INOUE KIYOKAZU
IPC: H03K17/60
Filed: 1980-08-22
Abstract: PURPOSE:To reduce a loss of electric power, by driving a load by a Darlington circuit which is operated as a Darlington transistor in case of a transient operation, and is operated as one transistor in case of a steady operation. CONSTITUTION:When a switch 4 is closed, a base current flows into a transistor 2 through a resistance 1 from a DC electric power source 5. Immediately after the switch 4 has been closed, voltage exceeding several volts is applied between the collector and the emitter (C-E) of the transistor 2, therefore, the base current flows through a resistance 7 to a transistor 6, too. This base current is hPE-multiplied by the transistor 6 and is supplied to the base of the transistor 2, therefore, the transistor 2 is capable of supplying a large load current to a load 3. As a result, voltage between C and E of the transistor 2 decreases as time elapses, the transistor 6 is turned off, and the base current is supplied to the transistor 2, only through the resistance 1.

Title: Manufacture of blazed grating
Inventor: ONO YUUZOU
IPC: G02B5/18
Filed: 1983-06-29
Abstract: PURPOSE:To obtain a transmission type blazed grating of high quality by coating a substrate with a negative type electron beam resist, irradiating the resulting resist film with electron beams, forming a relief grating which is ion-etched at a lower speed on the resist film, and carrying out ion etching using the grating as a shadow mask. CONSTITUTION:A substrate 1 is coated with a negative type electron beam resist, the resulting resist film 2 is irradiated with electron beams, and the irradiated resist film 2 is coated with a photoresist which is ion-etched at a lower speed than the film 2. The resulting photoresist film 3 is formed into a relief type diffraction grating, and the film 2 is ion-etched with ion beams in an oblique direction to the substrate 1 using the diffraction grating as a shadow mask. The resist film 2 is made insoluble in solvent when irradiated with electron beams, and the film 2 is incompatible with the photoresist coating the film 2, so a satisfactory relief grating is obtd.

Title: Device to prevent standing object from falling
Inventor: HAMAMURA HISAMITSU
IPC: A47B97/00
Filed: 1995-05-15
Abstract: PURPOSE: To prevent a standing object from falling by attaching a movable member which projects downward from the standing object every time the front of the standing object rise from the floor surface according to the sway of the standing object, and keeping the projecting position of the movable member against the load of the standing object by the engagement of a ratchet. CONSTITUTION: When the front of a chest is raised, an engagement member 13 is rotated by pulling the head 140 of an operation part 14, and a ratchet pawl 130 is disengaged from a ratchet tooth 120. When the chest is put down, a movable member 12 is stored inside the chest against the elasticity of a spring 122. When the pulling toward the operation part 14 is released, the engagement member 13 rotates to engage the ratchet pawl 130 with the ratchet tooth 120. If the chest is swayed by an earthquake, the front part of the chest is raised from the floor surface, and the movable member 12 projects from inside the chest by the elasticity of the spring 12 by the rise of the chest.  As the ratchet pawl 130 is engaged with the ratchet tooth 120 of the movable member when the chest is going to return to the front, the movable member 13 is kept projecting without being pushed inside, and slants toward the wall.

IPC: C03B11/08
Filed: 1993-04-19
Abstract: PURPOSE:To produce the mold for forming optical elements capable of executing molding without generating sink marks. CONSTITUTION:The porosity distribution of the blank of the mold is continuously changed in its diametral direction by removing specific components from the blank or impregnating the blank with the specific components. Powders varying in grain sizes and sp. gr. are successively charged into the mold and centrifugal force is acted thereon to continuously change the distribution rate in the diametral direction. The thermal conductivity of the mold after production changes continuously in the diametral direction and, therefore, the cooling after press molding of the glass is a single inclination and the sink marks are not generated.

Abstract: PURPOSE:To realize high-speed extraction and accurate control for the accumulated charge of a transistor (TR), by controlling the driving TR of a switching regulator by means of the negative voltage obtained by rectifying the switching pulse, the rectangular pulse obtained by integrating the switching pulse plus the DC output. CONSTITUTION:A switching pulse is applied between terminals I3 and I2.

The DC voltage of the output is fed back by a photocoupler 1. A driving TRQ2 having the pulse duration which is decided by the voltage of the triangular wave is turned on to turn on a switching TR. The base of the TRQ2 has the negative potential more than the emitter when the TRQ2 is turned off. As a result, the accumulated charge can be extracted in a high speed.
