Title: Data recording controller for floppy disk device
Inventor: KAWAGOE SEIJI
IPC: G11B20/10
Filed: 1988-06-30
Abstract: PURPOSE:To inhibit the data write if a magnetic recording medium with different designation recording density mode is set by detecting the recording mode commanded from a system and the mode of a magnetic recording medium and inhibiting the write of a write circuit if the result of comparison is dissident. CONSTITUTION:A disk controller 10 applies operation control of a disk drive (FDD) 11 and a write circuit 12 applies data write to a magnetic recording medium set to the FDD 11. The FDD 11 is provided with each logic gate circuit such as an exclusive OR circuit 13, OR circuits 14, 15 and a NOR circuit 16. Then the recording density mode of the magnetic recording medium is detected by a mode detection means 17 and when the result of comparison with the mode from the system is not coincident, the data write is inhibited. Thus, if a magnetic recording medium different from the recording density mode from the system is loaded, the data write is surely inhibited.

Title: Deaerated water injector
Inventor: ISHIGURO MASAAKI
IPC: A61B8/12
Filed: 1990-06-25
Abstract: PURPOSE:To enable the stopping of the supply of water quickly and accurately by switching a tank side piping section over to a position of being connected to an atmospheric air-releasing path when the supply of water is stopped while the tank side piping is made to communicate with the atmospheric air only for a specified time length by a path opening/closing means. CONSTITUTION:When a foot switch circuit 18 is operated, a signal thereof is inputted into a control circuit 19 to actuate an air pump 14 based on a signal from the control circuit 19 so that a switching of a passage changeover valve 15 and ON or OFF control of a shutoff valve 17 are accomplished. As a result, when the supply of water is stopped, the shutoff valve 17 is controlled to be opened by a time only necessary for the discharging of a pressure in a tank 10. A direction changeover valve can perform a switch between a first position that lets a tank side piping section 20a communicate with an air source side piping section 20b and a second position that lets the tank side piping section 20a and the air source side piping section 20b communicate with the atmospheric air. Thus, a switch of the direction changeover valve 21 from the first to second position enables the releasing of the pressure in the tank 10 to the atmospheric air thereby putting the air pump 14 into operation without load.

Title: Sheet carrier device, image reading device, and method thereof
Inventor: FUJII TAKAYUKI
IPC: B65H7/02
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To prevent an error in detecting a document size in a manual insertion carrier path by detecting the carrier distance of a sheet reaching a reference position, by comparing the detection distance with a practical distance, and judging whether there is some abnormality on the way to carrying or not. SOLUTION: When a manual insertion paper feeding is implemented, a document is carried inside a sheet path A by rotating a manual insertion paper feed roller 13 by a paper discharge motor 104, and then a manual insertion register sensor 34 judges whether the tip of the document passes the detection position of the sensor 34 or not. When the passing is detected, a manual insertion loop counter is started, and when the passing of the rear end of the document is detected, the counter is made to stop and the size is checked. That is to say, the carrier distance is detected based on the count value of the counter, the abnormality/normality of the document sliding on the way to carrying is judged by comparing the carrier distance with the practical distance, and when being judged abnormal, the length detected by a size detection means is set to invalid.

Title: Image signal binarizing device
Inventor: KATSUTA YUJI
IPC: G06V10/28
Filed: 1987-06-30
Abstract: PURPOSE:To faithfully binarize mixed originals by outputting '0' or '1' by utilizing a large difference from peripheral average density when a binarizing point is a two-gradation part, and in case of multi-gradation part, outputting the average density because of a small difference. CONSTITUTION:An analog signal of an original image is digitized by an ADC 1 and the average density in the prescribed range of 8X8 points is calculated by an arithmetic circuit 4. An adding PROM 5 outputs a value obtained by adding a prescribed value to the output of the circuit 4 and a subtracting PROM 6 outputs a value obtained by subtracting a prescribed value from the output of the circuit 4. Comparators 7, 8 compare the outputs of the PROMs 5, 6 with the output of the circuit 4, and in case of PROM 5 < circuit 4, the output of the comparator 7 is '1'. In case of PROM 6 > circuit 4, the output of the comparator 8 is '0'. When the density of a point to be binarized is similar to a peripheral average value, the output of the comparator 7 goes to '0', the output of the comparator 8 goes to '1' and binary data are outputted 13 from a comparator 10.

Title: Semiconductor device
Inventor: KUDOU SATOSHI
IPC: H01L29/73
Filed: 1980-11-25
Abstract: PURPOSE:To contrive to enhance the hFE and withstand voltage of a lateral transistor by a method wherein an N<+> type buried layer is provided protruding a part thereof as to face with a P type emitter and avoiding the directly under part of a collector and the neighborhood thereof. CONSTITUTION:An Sb diffusion layer 12 having the prescribed pattern is formed on a P<-> type Si substrate 1, and a P ion implanted layer 14 is formed applying an SiO2 mask 10. When the mask 10 is removed and an N type epitaxial layer 3 is formed, the N<+> type layer 2a is extended up to the part upper then the layer 2b by the difference of duffision speed. Element isolation, diffusion of the P type emitter and collector are performed in accordance with the usual way to complete the lateral P-N-P element. Because the N<+> type layer 2a having high concentration is protruded to the position directly under the emitter and being not to reach the collector, equilibrium concentration of implanted carriers from the P type emitter is reduced at least at the directly under part of the emitter, and the implanted carriers can be made to be diffused to the collector side effectively by electric diffusion potential to be formed at the neighborhood thereof. As a result, a collector current can be increased relatively in spite of breadth of the base to enhance the hFE. Accordingly breadth of the base can be spread to hold the hFE high and to reduce concentration of the base, and the device having high withstand voltage can be obtained.

Title: Idle speed control device
Inventor: KANAI HIROSHI
IPC: F02D41/14
Filed: 1984-08-08
Abstract: PURPOSE:To eliminate the necessity for an atmospheric pressure sensor and processing circuit in a control device and promote its cost down, by comparing an air-fuel ratio study correction quantity, obtained from an air-fuel ratio closed loop correction quantity, with a preset value and increasing an idle intake air flow when it is decided that an engine is driven in highland operation. CONSTITUTION:An air-fuel ratio study correction quantity FGHAC is compared with a predetermined set value C0, and if the compared result is in a relation where FGHAC<C0, a control device, deciding that an engine is diven on the highland or in a place at a low atmospheric pressure, generates an instruction signal opening a solenoid operated valve 32. And if the solenoid operated valve 32 opens, an intake air flow is increased by air flowing in a bypass intake passage 30. In this way, the control device, which can prevent an idle speed from decreasing on the highland, enables also an engine stall to be surely prevented. Thus the control device promotes its cost down eliminating the necessity for increasing also a number of terminals in a control circuit because the necessity, for providing separately an atmospheric pressure sensor while a circuit previously processing an output of the atmospheric pressure sensor, is eliminated.
