Title: Command reception system for scsi protocol control lsi
Inventor: MATSUMURA FUMIHIKO
IPC: G06F13/00
Filed: 1992-07-15
Abstract: PURPOSE:To provide a command reception system for SCSI protocol control LSI which can reduce the CPU program load of a device and improve the system efficiency. CONSTITUTION:When the message sent from an initiator via an SCSI bus is received together with the command of an LSI containing a buffer storing the commands, the buffer stores plural pairs of messages and commands sent from the initiator within the storage capacity of the buffer (St.1-St.20). The SCSI bus is disconnected while no message nor command is received. Then, an interruption is produced to a CPU when the capacity of the buffer is filled with the pairs of messages and commands. Therefore, the program burden on the CPU is reduced and the SCSI bus is disconnected by the original action of the LSI (St.19) when the command reception is finished. Thus, the bus occupying time is shortened.

Title: Phase locked loop oscillator
Inventor: MISAIZU KIMIHIDE
IPC: H03L7/18
Filed: 1987-08-24
Abstract: PURPOSE:To obtain a stable phase locked loop oscillator of a microwave band with simple constitution by providing a fixed frequency divider between a voltage controlled oscillator and a sampling phase detector (SPD). CONSTITUTION:A harmonic of a reference input signal of a reference oscillator 1 and a frequency division output being the result of frequency-dividing an output of the microwave band voltage controlled oscillator 5 by an analog frequency divider 4 are subject to phase detection by the SPD 2 and a control voltage is fed back to the voltage controlled oscillator 5 through a loop filter 3 to constitute the phase locked loop. That is, since the analog frequency divider 4 is provided between the voltage controlled oscillator 5 and the SPD 2, the input frequency to the SPD 2 is lowered and the phase detection sensitivity is taken sufficiently larger thereby constituting a stable phase locked loop. Thus, the stable phase locked loop oscillator with low phase noise and simple constitution is obtained.

Filed: 1985-09-20
Abstract: PURPOSE:To lighten the influence of an electromagnetic induction by setting the inter-line distance of lines whose current flow directions are reverse each other, and the inter-line distance of lines whose current flow directions are the same, shorter and longer, respectively, among lines with the harness constitution, which affect the electromagnetic induction with each other. CONSTITUTION:When an overheat detecting circuit 16R detects the overheat of one out of two combustion engines after the on-action of a main switch 46, a current is flowed to an earth wire 10 through the lines 14 and 15 to operate a buzzer 18R. When a detecting circuit 17R detects an oil reduction, the current flows into the earth line 10 through the line 15 to operate the buzzer 18R and a lamp 19R, and an operator can know abnormalities. At this time, the lines are wired so that the current flow of the lines 14 and 15 and that of the earth line 10 can be reverse each other, and the controller is free of the influence of the electromagnetic induction. When the overheat detecting circuit 16R and the oil reduction detecting circuit 17R operate, the oscillator circuit 95 of an engine rotation drop circuit 20R oscillates to conduct a thyrister 97. Then a plug 41 goes out and the combustion engine keep a low speed rotation.

Title: Oil pumping plant for stepless transmission
Inventor: OGAMI MASAAKI
IPC: F16H61/18
Filed: 1985-09-20
Abstract: PURPOSE:To normally control a hydraulic control system in a stepless transmission for gearshifting even if a first oil pump stops during car running, by installing the first oil pump driven by an engine and a second oil pump driven by wheels, either. CONSTITUTION:Power of an engine 1 is transmitted to a stepless transmission 4 and also transmitted to driving wheels 16 via a belt 11, thus a car runs. When the engine is driven, an oil pump 20a is also driven all the time by a pump shaft 17, producing hydraulic pressure there, and when a countershaft 6 rotates as the car runs, another oil pump 20b is also driven, producing the hydraulic pressure there as well. This hydraulic pressure is regulated by a line-pressure control valve 22, thus shift control takes place. With this constitution, even if the engine stalls in the state that a solenoid clutch is disengaged and/or a clutch 2 is disengaged at the time of fuel-cut to the engine 1, the oil pump 20b continues to produce the hydraulic pressure corresponding to the car speed, so that the shift control is performable.

Title: Polishing of ruby
Inventor: TSUKAMOTO YUJI
IPC: C30B33/08
Filed: 1994-09-02
Abstract: PURPOSE: To obtain a smooth surface of polished ruby by implanting a metal ion, the metal of which is selected out of Au, Ag, Cu, and Pt, onto the surface of a ruby material and then applying ion-etching to the surface. CONSTITUTION: One or more kinds of metal ions, the metal of which is selected out of Au, Ag, Cu, and Pt, are implanted in the surface of a ruby material on which mechanical polishing was carried out to the degree of a mean roughness of 10nm. Owing to this implantation of metal ions, the etching rate is enhanced by at least ten times. Meanwhile, the concentration of the metal ions implanted tends to become higher at a projected part of the surface, or the projected part selectively undergoes ion etching. As a result, a smoothing treatment, by which the surface having initial mean roughness of about 10nm, for example, is turned into the one having the mean roughness of about 1nm or under after the etching, can be done.
