Title: Trochoid pump for lubricating engine
Inventor: ISHIZUKA JUN
IPC: F04C2/10
Filed: 1985-08-30
Abstract: PURPOSE:To force fluid to be efficiently fed in a wide range of pump speed, by setting a suction port to communicate with a chamber-between-teeth of a trochoid pump, till the time said chamber obtains the maximum displacement, while generating a displacement change while the chamber-between-teeth is in closing. CONSTITUTION:When a chamber-between-teeth 9, formed by teeth of both trochoidally meshing rotors 4, 5, obtains the maximum displacement, a suction port 6 communicates with said chamber 9. In this way, a pump, increasing an effective area of the suction port, is prevented from generating a phenomenon of decreasing suction efficiency like cavitation or the like even in a high speed range. While the pump, decreasing a fine amount of the displacement of the chamber-between-teeth 9 while it is in closing, causes fluid with a lost destination to tend to flow out to the side of a delivery port 7 and the suction port 6, and the pump, preventing a leak of fluid from the delivery port 7 to the suction port 6 in a low speed range, improves pump efficiency.

Title: Electrophotographic base material
Inventor: YAMADA YOUJI
IPC: G03G5/10
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent toner from being scattered from a bank to the end of photoreceptor base material and to always obtain excellent image quality by forming a ring-like groove on an outer peripheral part on the outside from a photoreceptive layer formed area. SOLUTION: This electrophotographic base material 1 consisting of the photoreceptor base substance 2 having a photoreceptive layer 22 on the outer surface of a cylindrical conductive base plate 21, and a flange 3 and a gear 4 respectively fitted on both end faces of the photoreceptor is provided with the ring-like groove G on the outer peripheral part on the outside from the photoreceptive layer formed area. The groove G is formed to extend over the base substance 2 and the flange 3 or the gear 4 respectively. The groove G is formed on the base material 2, the flange 3 and the gear 4. Since the ring-like groove G is formed on the outer peripheral part on the outside from the photoreceptive layer formed area, the residual toner flowing along a blade 5 to the end of the base material 1 enters the groove 9 and is not scattered because it is not kicked by the blade 5.  Even though it is accumulated in the groove G, it does not drop as a lump, so that the image quality is not impaired.

Title: Refrigerating cycle
Inventor: OKITA YOSHIHIRO
IPC: F04C28/06
Filed: 1981-12-02
Abstract: PURPOSE:To prevent shortage of oil by, at the time of starting, allowing all the machines contained to operate for a certain period of time at full loads, by making even the oil levels through returning the oil in accordance with the progress of each cycle one after another to the compressor with underlubricated, and by eliminating unbalance of oil amount even though any machine is operated alone without provision of an oil equalizer pipe. CONSTITUTION:If compressors 1, 2 are started simultaneously, the oil returned from the cycle through the suction pipe 6 is the same for each compressor, but in case the current oil level in the compressor 1 is considerably lower than  the higheat possible level (oversurface of cylinder), the oil discharged in the  chamber together with the refrigerant gas is separated to fall off, and thereby  the oil amount will increase. In the compressor 2, on the other side, which  has contained the specified quantity of oil, most of the oil returned from the  cycle is again discharged toward the cycle together with the refrigerant. Thus  the oil in accordance with the progress of each cycle is returned one after  another to the compressor underlubricated, so that an even oil level is secured  during operation with a single compressor without requiring provision of any oil equalizer pipe. Thus oil shortage can be prevented.

Title: Wavelength variable semiconductor laser
Inventor: SAKATA HAJIME
IPC: H01S5/10
Filed: 1990-07-20
Abstract: PURPOSE:To sharpen wavelength selectivity by forming a multilayered type directional coupler capable of controlling couple wavelength in a laser oscillator and comprising the coupler so that it may be coupled by grating. CONSTITUTION:Electrodes 4a and 4b are classified into two regions, say, a gain region15 and a wavelength variable region 16 where individual current implantation is available. The current injected into the gain region 15 forces natural light emission to be produced by the recombination of carriers in the active layers 1. The light generated turns into 0 dimensional mode 21 which carries the active layer 1. On the other hand, the current injection forces the coupling in 0 dimensional and primary in a wavelength variable region 6 in terms of controlled wave length lambda. As a result, only the wavelength lambda out of the natural light emission the gain region 15 is cupled with that in primary mode in the wavelength variable region 16 where the light is shifted to a waveguide passage layer 2. The end face of the waveguide passage layer 2 is a crystal cleavage plane. The light shifted to the wave guide passage layer 2 is reflected on the end face and recoupled with the active layer, thereby producing feedback. When it exceeds threshold current, oscillation light 23 at the wavelength lambdais discharged. At that time, the oscillation wavelength lambda is controlled by the current injected into the wavelength variable region 16. This construction makes it possible to obtain a small- sized semiconductor laser which can extend the wavelength variable region.

Title: Voltage/current sensor
Inventor: SAKURAI YOSHIAKI
IPC: G01R19/165
Filed: 1989-07-28
Abstract: PURPOSE:To prevent a malfunction due to a variation of minute signal and an external disturbance by providing a insensitive body for a minute input value in the manner of getting a comparator to have the hysteresis characteristic. CONSTITUTION:An input voltage is applied to a terminal 5 of comparator C and a reference voltage is applied to a terminal 6, where the later can be changed by making a resistor VR1 variable. The comparator C is furnished with two reference voltages which are changed-over on the output signal level and constituted so as to compare with the input voltage. When the comparator C is set with a high reference value, the output signal is unchanged in just the state of L-level even if the input voltage is varied in the hysteresis width, and the signal is changed to the H-level to set a low reference value when the input voltage exceeds the reference value. A relay circuit is exerted when the signal is made to be H-level and made nonoperative when it becomes L-level, then the high reference value is set at the same time and this state is repeated by the variation of input voltage. The malfunction caused from the minute signal variation and external disturbance can be prevented by providing the insensitive range according to the hysteresis characteristic.
