Title: Apparatus for lessening speed change shock of automatic transmission
Inventor: OOTSUKA KUNIO
IPC: F16H61/04
Filed: 1983-06-03
Abstract: PURPOSE:To lessen the speed change shock, by providing a low clutch pressure- reducing valve for reducing the hydraulic pressure directed to a low clutch in a state wherein the third speed is selected. CONSTITUTION:A low clutch pressure-reducing valve 801 for reducing the hydraulic pressure directed to a low clutch C3 in a state wherein the third speed is selected is provided to a low clutch working pressure oil line connected to a low clutch C3. Thus, if, in a state wherein the third speed is selected, the input torque ratio of the low clutch C3 is made low, its clutch capacity can be made to have a required clutch capacity corresponding to the input torque by the involved speed change stage. As a result, the speed change shock that will result in when the low clutch C3 that is not in operation is to be changed to be operated, that is, the four speed is changed to a third speed can be positively lessened.

Title: Carrier-driving device for serial printer
Inventor: IMAI MINORU
IPC: F16H7/10
Filed: 1985-05-09
Abstract: PURPOSE:To automatically provide a spring material with a tensile strength to cope with its stretch to improve its durability and to prevent positional deviation of carriers by providing a pressure plate which has two legs that are abuttingly provided on exterior surfaces of the frames that are facing each other and deflected towards inside, and a pressing portion which is located in the middle of the legs and pushes supporting members towards outside of the frames. CONSTITUTION:Since a left supporting member 2 is pushed towards left side by a pressure plate 5, a belt 6 is kept in tension. If the belt 6 stretches during prolonged use, the pressure plate 5 moves correspondingly to the stretching to gradually move the supporting member 2 towards left, and the belt 6 is automatically provided with an appropriate tensile strength. No excessive tensile strength is given to the belt 6, and its life is extended. After the belt is provided with the tensile strength, the leg 3 does not open towards because of its elasticity and interlinking with a protrusion, and the supporting member 2 is kept under a static condition. Therefore, regardless of a difference in a moving direction of the carrier, either forward or backward, a stretching or a shrinking of the belt 6 is prevented, and the positional deviation of the carrier 8 is also prevented.

Abstract: PURPOSE:To obtain a display screen which has high color purity over a wide screen by installing a wavelength selecting member which diffracts light to narrower wavelength bands of respective spectra than a color filter on the optical path connecting a light source and an optical modulating element. CONSTITUTION:The wavelength selecting member 2 which diffracts the light spectrally to the narrower wavelength ranges of respective spectra than the color filter on the optical path connecting the light source 1 and optical modulating element 4 is installed. Then the light of a halogen lamp 1 as the light source is transmitted by the wavelength selecting member 2 constituted by sandwiching a birefringent plate between two polarizing plates and guided to a light guide member 3 to obtain a linear light source. Further, a liquid crystal shutter cell 4 which is the optical modulating element transmits the light from this linear light source spectrally. The light emitted by the shutter cell 4 is determined by multiplying the spectrum of a gelatin color filter and the spectrum of the wavelength selecting member 2; and its wavelength range is narrow and there is no wavelength overlap part between colors. Consequently, the crosstalk of writing light becomes small and a print color range where the color purity is high can be printed as a color print of high quality or displayed out.
