Title: Disk file access system
Inventor: HACHITANI MITSUGI
IPC: G06F3/06
Filed: 1985-05-27
Abstract: PURPOSE:To attain a file access at a high speed by storing all file index parts within a disk device requiring an access into a CPU and the access frequency is minimized to these index parts. CONSTITUTION:When an applied program 7 accesses the data on a certain logical position of a file 3, the program 7 retrieves a specific one of indexes 8 within a CPU 2 that is equal to the corresponding index part. Then the program 7 designates the retrieved index part and issues a request to a disk operating system of software DOS6 to access the file 3. The DOS6 checks whether or not the designated index part corresponds to the requested data. The indexes 8 correspond to indexes 4, therefore, no replacement is carried out with indexes 8. Then the file 3 is accessed according to the designated index part.

IPC: H01L21/8222
Filed: 1982-07-02
Abstract: PURPOSE:To realize a relatively high operation speed and to reduce an input current, by using a CML gate. CONSTITUTION:An input level conversion part 1 receives and converts an input signal at a TTL level to a signal level conforming to the logical signal of an internal logical gate part 2. The internal logical gate part 2 is composed of the CML logical gate for high-speed processing to perform desired logical processing operation. An output level conversion part 3 receives and converts a signal which is generated by the internal logical gate part 2 and to be outputted and the signal is converted to the TTL signal level, to output to external terminals OUT1-OUTn. Thus, the CML gate is used to increase the operation speed as compared with a TTL gate, and a diode logical circuit similar to the TTL gate of an LS type is usable for the input level converting circuit, so the input current is reduced to increase the number of fan outs correspondingly.

Abstract: PURPOSE:To prevent a malfunction of a clock circuit due to piezo-voltage, by providing a diode for discharging the piezo-voltage, to an electric power amplifying part for driving a piezoelectric buzzer. CONSTITUTION:When a DC rectangular current signal is outputted from a buzzer signal output terminal of a clock circuit 1, a transistor 7 is turned on and off, DC sqaure wave voltage whose peak vlaue is equal to output voltage of a battery 5 is generated in an output terminal 23 of an integrated circuit 6, and by this voltage, a piezoelectric element 4 is driven.

Title: Self-feeder for sheet
Inventor: SAWADA GENBEE
IPC: B65H3/10
Filed: 1981-07-22
Abstract: PURPOSE:To miniaturize a device and to improve a feed performance, by constituting a feeder such that a large number of vent holes are formed in a peripheral surface of a convey roller for a copying machine to suck a paper from the inside of the roller, the suction holes are specified in a part positioned facing and opposite to a sheet, and the roller is normally brought into contact with the sheet surface. CONSTITUTION:A convey roller 20 is turned in a direction of an arrow mark C, and the inside of the roller is brought to a negative pressure through an ari pressure feed pipe 40. The negative pressure acts on a given hole part 23 through the working of a beltlike opening of a hollow part 25 to adsorb an uppermost sheet 11. Thus, the sheet is adsorbed to the roller 20 for conveyance to deliver it to a roller 53. A second sheet is then adsorbed and is conveyed in a similar manner. If the loading amount of the sheets changes, a moving arm 37 rotates to move downward the convey roller 20, which results in normally bringing the convey roller 20 into contact with the sheet (11) surface. This constitution permits miniaturization of a device and the conveyance of the sheets one by one irrespective of the sheet material.

Abstract: PURPOSE:To attain high speed and to attain sufficient external drive capability by decreasing the size of the gate width of a switch FET and increasing the gate width of a drive FET among FETs constituting an R/S flip-flop so as to make the FETs optimum to respective functions. CONSTITUTION:The size Wg1 of the gate of the FET of a switch circuit 1 is selected smaller than the gate width Wg2 of the FET of a drive circuit 2 in the R/S flip-flop circuit.

Thus, high speed switching of the circuit 1 is attained. On the other hand, since the gate width Wg2 of the FET of the circuit 2 is selected larger than the gate width Wg1 of the circuit 1, a sufficient drain current is obtained. Thus, the external drive capability is made sufficient for the circuit 2.
