IPC: F16K31/40
Filed: 1989-12-13
Abstract: PURPOSE:To make the above valve compact by small driving power without an influence of action of a fluid pressure by balancing a pressure, applied to a valve unit, by means of the valve unit for adjusting a flow amount and a pressure-receiving unit having a pressure receiving area equal to the valve unit. CONSTITUTION:When a solenoid 6 is energized, a pilot valve 24 is attracted to a plunger 7 against urging force of the second spring 23 to open a communica tion hole 21 with a pressure generated in a back pressure chamber 20 equal to that in the secondary side of a water stop valve 14. Here, because a pressure receiving area is equally constituted in the stop valve 14, flow regulating valve 15 and a pressure receiving unit 16, the respective primary and secondary sides thereof are balanced, and the valves 14, 15 and the unit 16 are held by urging force of the first spring 17. Next, when energization to the solenoid 6 is further increased, the plunger 7 is pressed down against the urging force of the spring 17, and a shaft 11 is pressed to open the stop valve 14 with a flow amount dominated by the flow regulating valve 15. That is, by adjusting a current value flowing in the solenoid 6, an opening area, formed by the flow regulating valve 15, is changed to adjust the flow amount of fluid.

Title: Magnetic disk and manufacture thereof
Inventor: ECHIGO FUMIO
IPC: G11B23/00
Filed: 1990-11-26
Abstract: PURPOSE:To make it possible to obtain a magnetic disk having large adhesion strength by producing a specific chemical bonding between a magnetic sheet and a metal hub. CONSTITUTION:A triazine thiol chemical compound indicated in the equation 1 is used as a coupling agent when bonding a magnetic sheet with a metal hub and pressure-bonded under the application of heat. The term R in the equation I stands for - SH, grade 2 amin, grade 3 amin, while M for H, alkali metal, and alkaline earth elements. Since the triazine thiol chemical compound has reactivity against a high polymer chemical compound in a metal and magnetic layer in this manner, definite bonding between the metal hub and the magnetic sheet can be expected. This construction makes it possible to prevent bonding deviation between the metal hub and the magnetic sheet and hence obtain a magnetic disk having high bonding strength.

Title: Computer system and transfer of data
Inventor: RABUI KUMAARU ARIMIRII
IPC: G06F13/40
Filed: 1989-12-15
Abstract: PURPOSE: To improve the efficiency of block data transfer by reading a data item from a device during each bus clock cycle of that device and writing the data item of that device during each bus clock cycle of the other device at the time of data transfer. CONSTITUTION: An input/output cache controller(IOCC) 20 is connected to a system bus 12 and an input/output bus 14. The IOCC 20 is operated as a direct memory access (DMA) controller and when functioning it as the DMA controller, data can be directly transferred with a main storage device 18. Namely, the DMA controller 20 connected to two buses 12 and 14 performs reading from one bus simultaneously with writing to the other bus. The data transfer is performed during the respective clock cycles of the respective buses 12 and 14. Thus, since waiting is not required even on any bus 12 or 14, block data can be efficiently transferred while using high-speed block transfer technique which can be used on the bus.

Title: Molecular beam crystal growing method
Inventor: SUGATA SUMIO
IPC: H01L21/203
Filed: 1989-12-15
Abstract: PURPOSE:To improve the interface sharpness and the acceptor concentration of a thin film, by using carbon radical obtained by decomposing hydrogen carbide as dopant, and obtaining P-type III-V compound semiconductor. CONSTITUTION:A molecular beam crystal growing equipment is equipped with a radical generating equipment 3. A substrate 9 is irradiated simultaneously or alternately with carbon radical 7 and with other molecular beam, thereby obtaining P-type crystal of III-V compound semiconductor. Carbon is an amphoteric element for III-V compound semiconductors. When carbon atoms enter a group III lattice, they act as donars and the III-V compound semiconductor exhibits N-type. When the carbon atoms enter a group V lattice, they act as acceptors, and the semiconductor exhibits P-type. Since the diffusion coefficient of carbon is smaller than that of other P-type dopant like Be, Mg, and Zn, a thin and sharp interface can be easily obtained. But solid carbon is not easy to be used, and its gas is preferable, so that hydrogen carbide is previously decomposed and turned into radicals by plasma discharge using electron cyclotron resonance or by light or energy.
