Title: Scroll compressor
Inventor: TAGUCHI TATSUHISA
IPC: F04C18/02
Filed: 1990-04-09
Abstract: PURPOSE:To maintain the friction coefficient of a radial bearing at a low value even in a high speed rotation area by providing recesses whose mean depth is 10 times or more of the radius clearance at the side surface center, on the reverse side of the load of an eccentric shaft and an eccentric bearing of a shaft. CONSTITUTION:A recess 5a is formed at the center of the right half of the larger shaft 5 of a shaft used in a scroll compressor. And a recess 6a is formed at the center of the right half inside a rotary bearing 6 in the same manner. The mean depth of the recesses 5a and 6a is made about 10 times or more of the radius clearance of the bearing 6. As a result, a loss by the viscosity resistance of the oil flowing in the clearance on the surface at the reverse side where almost no function is necessary as a bearing is reduced. Consequently, the friction coefficient of the radial bearing can be maintained at a low value even in a high speed rotation area.

Title: Video tape recorder
Inventor: OKADA MASATAKA
IPC: G11B15/08
Filed: 1982-06-01
Abstract: PURPOSE:To prevent the misuse of a tape, by disabling the tape reproduction with a relay in case a photocoupler of a VTR deck detects a reflecting plate provided to a VTR cassette and then enabling the tape reproduction with a specific key. CONSTITUTION:The light beam of a light emitting element 2 is reflected toward a photodetecting element 3 by a reflecting plate provided at the side surface of a VTR cassette half (not shown in the diagram). Then an amplifier 9 generates an output after detecting that the cassette half is loaded. This output of the amplifier 9 opens a relay contact 5. Then the power supply of a deck (not shown in the diagram) is cut off to disable reproduction. While a key switch 6 is closed by a specific key 7, and then the power supply of the deck is switched on to enable the reproduction. The contact 5 is closed to enable the reproduction with an oridinary cassette having no reflecting plate. Thus the reproduction is impossible for a specific cassette for persons except the owner of the key 7, thereby preventing the misuse of a tape.

Title: Multiplex power supply
Inventor: AZUMA SEIYA
IPC: H02M3/28
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To enhance operating reliability by detecting overcurrent of a DC stabilization power supply unit for sending out a duplex recognition signal to a DC stabilization power supply unit and changing an overcurrent detection value upon receiving a duplex recognition signal. SOLUTION: When a DC/DC converter 1 operates normally, the transistor Q1 of a multiplex recognition signal generating circuit is turned on, so that the multiplex recognition signal is sent from the output terminal INS of the DC/DC converter 1 to the input terminal OCC. The multiplex recognition signal outputted from the output terminal INS of the DC/DC converter 1 is inputted into the input terminal OCC. Voltage across a sense resistor R1 obtained by a comparator CMP1 is compared with a reference voltage Vz by a comparator CMP2, and if the voltage across the sense resistor R1 exceeds the reference voltage Vz, a overcurrent detecting circuit discriminates it as a state of overcurrent. It is thus possible to attain the precision of overcurrent detection with the DC stabilization power supply unit connected for operation to the same degree as for a case where it is not used.

IPC: B41J2/28
Filed: 1989-04-13
Abstract: PURPOSE:To reduce the number of components, and to obtain a printing head adapted for inexpensively printing at a high speed by composing an armature unit for driving a printing wire of an armature block, and an armature arm secured at one end to one end of the wire and at its lower end to a spacer via the hole of a leaf spring. CONSTITUTION:When a print command is received, a current flows to a coil 6 to generate a magnetic force opposite to that by a permanent magnet 1 in a yoke 3. Accordingly, the magnetic force by the magnet 1 is cancelled, and an armature block 4 is separated from the yoke by elastic energy stored a deflected leaf spring 7 and at the end 12a of the armature arm 12. Thus, a printing wire 13 coupled to the block 4 via the arm 12 is operated in a direction of an arrow X to print a dot via an ink ribbon on a printing sheet. Since the lower end 12a of the arm 12 is secured to a spacer 8 having sufficient rigidity, the block 4 released from the yoke 3 is restricted to move in the X direction of the block 4 to accelerate the returning motion (Y direction) of the wire 13.

Title: Strobe triggering device
Inventor: MASUNAGA MAKOTO
IPC: G03B15/05
Filed: 1981-06-18
Abstract: PURPOSE: To obtain a triggering device which provides secure strobe synchronization even when a subject is bright and an aperture is less, by generating a strobe signal upon occasion after the time necessary for shutter curtains to open through a timer.  
     CONSTITUTION: When a subject is bright, the period when a control signal from a shutter control circuit 2 to an electromagnetically driven shutter is at a high level is shorter than the timer period when the output of a timer 10 is at the high level, and the low-level inverted output of the timer 10 passed through an OR circuit 12 triggers a strobe. Therefore, even if the shutter control signal is interrupted before shutter curtains are opened, the strobe is triggered through the timer 10 after a shutter curtain opening period. Thus, a strobe triggering device which achieves strobe synchronization securely even when a subject is bright and a shutter aperture is less is obtained.
