Title: Falling device of flexible film dam
Inventor: ENAMI YASUSHI
IPC: E02B7/20
Filed: 1982-11-17
Abstract: PURPOSE:To make easier the raising operation of a flexible film dam after being fallen down by a method in which a lever with a weight is set to the rotary shaft of a discharge butterfly valve, one end of the lever is connected to a bucket connected with the upstream side of the flexible film dam, and the other end of the lever is connected to the upside of the operation chamber. CONSTITUTION:A lever 10 with a weight 11 for opening or closing a valve 8 consisting of paired arms 12 and 13 is set to the rotary shaft 9 of a discharge butterfly valve 8. The arm 12 of the lever 10 is connected to a bucket 15 connected to the upstream side of the flexible film dam 1, and the other arm 13 is coupled with a hook 22 provided to the floor 20 of an operation chamber 6. As water in the dam 1 is discharged and the dam 1 is fallen down, the level of water in the upstream side of the dam 1 is gradually lowered and the amount of water in the bucket 15 is also reduced. Since the force to return the lever 10 counterclockwise is gradually weakened, the lever 10 is gradually clockwise turned under the gravity of the weight and the discharge valve 8 is eventually changed to fully opened state.

Title: Phase difference adjusting method in photoelectric encoder
Inventor: YOKOKURA TAKASHI
IPC: F02B75/02
Filed: 1991-08-09
Abstract: PURPOSE:To obtain a phase difference adjusting method in a photoelectric encoder which can eventually remove the phase difference present in the grating pattern only by a simple operation. CONSTITUTION:The light generated from a light source 4 is detected by photoelectric converting elements 61, 62 via a condenser lens 5, a moving grating 1, and a fixed grating 2 having two coding patterns relatively arranged with approximately 1/4 cycle of the grating pitch (90 deg. in terms of the phase angle). When the phase difference between the first and second signals detected by the photoelectric converting elements 61, 62 is larger than a predetermined phase difference, the distance between the light source 4 and the condenser lens 5 is made large. If the phase difference between the first and second signals is smaller than the predetermined phase difference, the distance of the light source 4 from the condenser lens 5 is reduced. In this manner, the predetermined phase difference is ensured.

Title: Sphygmomanometer
Inventor: MATSUMOTO KOJI
IPC: A61B5/022
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to eliminate the need for a valve intended for a leakage test and carry out a performance test for a constant speed exhaust valve. SOLUTION: This phygmomanometer is equipped with a main body 1 incorporating a pump 31 and a constant speed exhaust valve 33, and a cuff 2 mounted on the main body detachably. The cuff 2 has connections with the pump 31 and the constant speed exhaust valve 33, the pump 31 and the constant speed exhaust valve 33 are connected through the cuff 2. As the removal of the cuff 2 from the main body 1 cuts the connection between the pump 31 and the constant speed exhaust valve 33, a leakage test for the pump 31 requires only the removal of the cuff 2 from the main body 1, the supply of compressed air to the pump 31 side and the measurement of leakage. With the cuff 2 removed, supplying compressed air to the constant speed exhaust valve 33 side helps confirm the performance of the constant speed exhaust valve 33.

Title: Method for detecting residual quantity of toner in two-component developing device
Inventor: OKUI KIYOSHI
IPC: G03G15/08
Filed: 1990-07-31
Abstract: PURPOSE:To precisely detect the residual quantity of toner by forcibly shifting the count value of toner consumption to a first set value when a toner replenishing action over a prescribed time is executed after a toner consumption frequency becomes over a second set value. CONSTITUTION:A consumption count level N2 being an empty state such an extent that the toner does not drop from a toner container when it fills up the toner container in the case that the toner is replenished by a toner cartridge is set between the toner consumption frequency N1 until a developing device is forcibly stopped after the residual quantity of the toner in the toner container becomes at a prescribed level or under by a ordinary consumption level and a consumption count level N3 that alarm display is executed. In the case that the count value of the toner consumption frequency is between N1 > N2, the ordinary detecting action of the residual quantity is executed. On the other hand, when the count value becomes <= N2, it is forcibly shifted to the first set value N3 and the alarm display is executed. Thus, the residual quantity of the toner is precisely detected even in the case that the continuous replenishing action of the toner for solid black printing or the other is executed when the residual quantity of the toner becomes near the depleted state.

Title: Electrically controlled pump nozzle for injecting fuel for diesel internal combustion engine
Inventor: JIYAN RUBURAN
IPC: F02M57/02
Filed: 1985-09-13
Abstract: The unit fuel injector has a pump piston driven at a constant stroke length, which pumps fuel at injection pressure to an injection nozzle as long as an electrically actuated overflow valve blocks the flow of the fuel flowing from the pump work chamber to a low-pressure chamber via an overflow conduit. The overflow valve is inserted between a first section which communicates continuously with the pump work chamber and a second section leading to the low-pressure chamber of the overflow conduit and is secured to a housing part laterally projecting from the pump housing. The first section of the overflow conduit comprises a connecting bore leading away from the pump work chamber, a control conduit controlled by the overflow valve, and a transverse conduit connecting these two. The transverse conduit extends from the housing side remote from the projecting housing part to the control conduit, crossing through the cylinder bore and in every stroke position of the pump piston is sealed off, without additional sealing means, by the jacket face of the pump piston. The unit fuel injector is particularly suitable for high-pressure injection in Diesel engines.
