Patent JP-H04338038-A (JP)
Title: Sheet feeder
Inventor: ITO YOSHIYA
IPC: H04N1/00
Filed: 1991-05-14
Abstract: PURPOSE:To provide a proper sheet feed interval with a simple construction by eliminating the vertical movement of a pick up roller to secure it and starting the rotation of the pick up roller by a one-way clutch upon the the start of rotation of a feed shaft. CONSTITUTION:A roller shaft 14 is provided traversing the sheet feed direction and in parallel with the surface of a recording sheet 13 mounted on a cassette 12 at a constant height. Accordingly, the recording sheets 13 abut against a pick up roller 15, so that the height of the roller shaft can be easily determined. A feed shaft 21 is driven keeping time with a sheet feed timing by a driving source 20. On the feed shaft 21 are supported a feed gear 22 with a one-way clutch 22A and a feed roller 23. The driving source 20 drives and rotates the roller 15 and the roller 23 through an idler gear 24 meshing with the gear 22 during driving and a pick up gear 15A. Accordingly, when the rear end of the recording sheet 13 passes the roller 15, the roller 15 is not rotated until the driving of the feed shaft 21 is started. Thus, a proper sheet feed interval is formed between the preceding recording sheet 13 and a succeeding recording sheet.

Title: Master cylinder
Inventor: MARUYAMA TERUO
IPC: B60T11/224
Filed: 1978-09-01
Abstract: PURPOSE: To prevent drag and obtain a stable brake effect by setting up a single check valve between a reservoir and a liquid pressure room and simultaneously performing the liquid compensation from the reservoir to the liquid pressure room and its feedback from the former to the latter.  
     CONSTITUTION: When the piston 14 moves left by the pedal stepping force, the piston projection 32 and the first valve projection 31 are disengaged. Since the first valve 28 sealing-engages with the first valve seat 33, the communication between the reservoir 27 and the large diameter room 19 is disconnected. The liquid pressure of the large diameter room is supplied to the wheel cylinder through the first path 22, first cup rear 23, second path 24, small diameter room 21, and outlet port 20. This liquid pressure is comparatively low, but the quantity of liquid is large. When the large diameter room liquid pressure exceeds the preset value, the second valve 29 is released from the valve seat 36 and the liquid pressure of the large diameter room 19 is released to the reservoir 27. It decreases below that of the small diameter room 21 and the communication of both rooms is disconnected.

Filed: 1988-05-06
Abstract: PURPOSE:To measure a magnetic field repeatedly and continuously by supplying a current larger than a critical current which transits to normal conducting state to a material in a superconducting state and detecting magnetic flux which is discharged by Meissner effect entering the material. CONSTITUTION:The rod-shaped material 1 which becomes superconductive and the cylindrical normally conducting material 3 which surrounds it are placed in the insulat ing material of the spool 2 of a coil 4 for magnetic field detection. A switch 6 is turned on and off according to a signal from a trigger circuit 8 to supply the current Is larger than the critical current to the material 1 in the superconducting state inter mittently, and thus the material 1 is made normally conductive to eliminate the Meissner effect. Consequently, the magnetic flux which is discharged from the material 1 enters the insulating material from the outside to generate an electromotive force at the coil 4. This electromotive force is like a short pulse, so the velocity of the magnetic flux is adjusted and reduced by the normally conducting material 3 to lower the pulse voltage and to increase the pulse width the electromotive force, thereby easily measuring a voltage. The voltage is measured by an AC voltmeter 5 to obtain a signal proportional to a magnetic field, which is measured in an almost stationary state.

Abstract: PURPOSE:To suppress vibration of a linear-shaped hot cathode momentarily by furnishing a restricting means for the hot cathode substantially in parallel therewith, forming a specific restricting surface in the longitudinal direction of the hot cathode, and providing a specific slope at the end on its outside in longitudinal direction. CONSTITUTION:When an external force such as shock is applied to a display device, a linear-shaped hot cathode 4 vibrates with its No.1 node located at the outer ends 5e, 5g of a pair of restricting means 5a, 5b while No.2 node situated at the inner ends 5h, 5h of a pair of restricting means 5a, 5b. Because the No.1 and No.2 nodes become the node of vibration of the hot cathode 4 alternately, its vibration is hard to come into resonant condition. Further the restricting means 5a, 5b stretch in the longitudinal direction of the hot cathode 4 and have 0.02L-0.1L long restricting surfaces 5c, 5d in the longitudinal direction of the hot cathode 4, wherein the restricting surfaces 5c, 5d outside ends in longitudinal direction of the hot cathode 4 are formed from slopes 5i, 5j under thetaa=20deg. Accordingly the hot cathode 4 smoothly contacts these restricting surfaces 5i, 5j, and its vibration energy is absorbed. Thus vibration of the hot cathode 4 can be suppressed momentarily.
