Title: Power steering device
Inventor: KOMAMURA SEIJI
IPC: B62D6/02
Filed: 1981-03-02
Abstract: PURPOSE:To prevent the unstability of the steering handle operation by stopping the pump drive and changing the steering to the manual steering in the high speed region. CONSTITUTION:In the high speed region a magnetic clutch 10 is de-energized as a car speed detection switch 14 is turned off, and therefor a pulley 11 only run idle without driving a pump 6. Thus, when a steering handle is perated no hydraulic assit acts on a piston 4 of a power cylinder 3 as there is no oil supply from the pump 6 although a control valve 5 is changed over. However, the piston 4 rotates a pinion 8 via a rack 7 to drive a steering like 8a as it is thread engaged with an input shaft 2. When the car speed is reduced and the car speed detection switch is turned on the normal power steering action is performed by receiving the power assist.

Title: Artificial synthesis of single crystal of beryl
Inventor: SATO KEIJI
IPC: C30B9/12
Filed: 1985-02-18
Abstract: PURPOSE:To obtain a large sized single crystal of beryl by synthesizing a single crystal using a flux composed of starting material for the parent material having a particle size within a specified range. CONSTITUTION:Powdery starting materials for the parent material having 2-0.1mu particle size consisting of BaO, Al2O3, SiO2 and several kinds of colorant are used in the synthesis of single crystal of beryl together with flux. Narrower range of the particle size distribution of the parent starting material is preferred. The particle size of SiO2 should be strictly controlled because the proportion of SiO2 in the starting material is large. The particle size of BeO and Al2O3 are preferred to be 1-0.1mu. If the particle size is smaller, the particles are liable to conglomerate, or to scatter, causing difficulty in handling, resulting insufficient mixing leading to inferior reproducibility. If the particle size of the starting material is too large or the distribution of the particle size is too wide, the solubility of the starting materials becomes uneven, so satisfactory growth of crystal is not realized.

Filed: 1982-02-26
Abstract: PURPOSE:To perform communication from one station to plural stations effectively by transmitting a signal from an originating station to adjacent stations together with an additional sequence number which has a longer repetitive period than the difference between maximum delay time and minimum delay time in a communication network and an added originating station name. CONSTITUTION:This describes only the transmission and reception of a signal 511 with the transmission and reception timing 51 of a station 1 by the transmission and reception timing signals 52, 53-55 of other stations 2, 3-5 when the station 1 originates. In this case, the minimum delay time (b) is delay time between the stations 1 and 5, and the maximum delay time (a) is delay time between the stations 1 and 3 through the station 5. Each station has a counter for every sequence number of an originating station and drives the counter by an up-to-data signal; once its counted value reaches signal delay time (c), the counter is reset. A signal with the same sequence number of the same station received during the counting operation is discarded and a signal received while the counter is reset is decided to be the up-to-data signal, which is sent to adjacent stations.
