Title: Hydraulic pressure control valve
Inventor: KUBOTA HITOSHI
IPC: B60T8/26
Filed: 1986-03-18
Abstract: PURPOSE:To improve the production efficiency by always obtaining the desired hydraulic characteristic by setting the length ranging from the contact surfaces between a pair of plungers to the shoulder part of the plunger longer than the length in the direction of axis line of a sleeve. CONSTITUTION:The length L2 between the contact surface 23a of a plunger 23 and a shoulder part 26 which contact each other is set longer than the length L1 in the direction of axis line of a sleeve 21 so that the plunger 23 projects from the sleeve 21. Therefore, the load varies in the variation portion DELTAl between a valve seat 5 and a valve piece 28 in the case when one of two plungers 23 and 23 shifts within the range of the dispersion of the spring 12. With such constitution, the delay of the valve opening time in operation and the rise of the cut point are prevented, and the desired hydraulic characteristic can be always obtained, and the production efficiency can be improved. Further, the hydraulic characteristic test after the completion of assembly can be omitted.

Title: Camera using film with information
Inventor: SATOU AKIHIKO
IPC: G03B7/24
Filed: 1982-04-12
Abstract: PURPOSE:To obtain a camera which has a readable nonvolatile storage means while its circuit is simplified, by storing detected information in an electrochemical storage element. CONSTITUTION:An electrolyte 42 is polarized by a potential drop between both terminals of a memory cell to flow a current and a metal set on an outer circumferential electrode 40a is accumulated as a metal 43 on a center electrode 41a. When the potential is inverted to flow a large current, the accumulated metal 43 is diffused in the electrolyte 42 again to be set on the outer circumferential electrode 41a again. Namely, when this element is used as a memory, a current is flowed from the terminal 40 to the terminal 41 to erase information and the current is flowed from the terminal 41 to the terminal 40 to write information. Thus, the camera having the readable nonvolatile storage means by the simple circuit is obtained.

Title: Recording sheet holder
Inventor: YOSHIZAWA ATSUTOMO
IPC: B65H9/08
Filed: 1986-03-20
Abstract: PURPOSE:To enable sheet feeding with a constantly fixed accurate sub-scanning quantity, by controlling a suction force supplied to a suction part for holding a recording paper at a recording part according to the width of the paper in a main scanning direction. CONSTITUTION:A negative-pressure regulating valve 12 is disposed in a branch pipe 11 branched from a suction pipe between a suction blower 7 and a distributor 5. The terminal end of the branch pipe 11 is opened into the atmosphere. When a recording paper 8 held by suction onto suction parts 3A, 3B is a large- width paper 8B, the recording paper 8B is attracted by suction through both of the suction parts 3A, 3B, in which case the valve 12 is opened to taken in the atmospheric air, thereby decreasing a negative pressure. When the recording paper 8 is a small-width paper 8A, the valve 12 is not opened, and a suction force per unit width at the suction part is maintained to be uniform. Accordingly, by controlling the suction force according to a sheet width, a constantly accurate sub-scanning quantity can be maintained during sheet feeding, irrespective of the size of a recording sheet.

Abstract: PURPOSE:To obtain a thin, small-sized device and to prevent malfunction, by fitting a latch and an operation button which operate independently of each other to a device fixation part at right angles to an insertion opening surface for a recording medium in an overlapping state. CONSTITUTION:A storage case fitted to the device fixation part which is not shown in figures contains the operation button 8 and latch 9 in the overlapping state so that they are capable of sliding independently of each other at right angles to the surface of an insertion opening 21 for a recording medium. In the upper figure the latch 9 engages a hole 10 during the operation of the disk operation to power on a solenoid 18, and a plunger 19 and a coupling line 20 are moved as shown by an arrow (a) to release a pawl 15 and the latch 9 from coming into contact delta4. The lower figure shows that the operation button 8 is pressed in as shown by an arrow (b) by mistake during the operation of the device and the pawl 15 and latch 9 are released from contacting each other, so the push button 8 moves individually as shown by an arrow (b). Consequently, the latch 8 and hole 10 are held in the engaging state. Namely, even when the operation button 8 is pressed in by mistake during the operation of the device, the door is never released from being unlocked.

Title: Discharge lamp lighting device
Inventor: YAMANAKA YUKIO
IPC: H05B41/42
Filed: 1991-03-26
Abstract: PURPOSE:To precisely detect the life end state of a discharge lamp without having an influence of dimming operation by stopping the life end state detecting operation for a determined time when the light output is controlled in the increasing direction at the time of dimming. CONSTITUTION:When the state where a switch SW3 is on in dimming state is changed to the state where SW3 is off in full-lighting state, a trailing trigger signal is received by a trigger terminal, and a pulse signal with a fixed time width is outputted from an output terminal. Thus, when the dimming state is transferred to the full lighting state, the standard voltage is temporarily increased in a fixed period T in which the pulse signal is outputted from a timer circuit IC1, and thereafter changed to the standard voltage for full lighting. Therefore, after the dimming state is switched to the full lighting state, the detecting operation of life end of a discharge lamp La is substantially stopped for the fixed time T, whereby the erroneous operation is eliminated.
