IPC: G11B23/28
Filed: 1990-09-28
Abstract: PURPOSE:To protect a program from an intended abuse by checking the position of the hole of a storage medium in which the program is stored, and judging the execution of the program by the result. CONSTITUTION:When a program 4 stored in a disk storage medium 1 is read out from the magnetic medium 1 by a program reading executing means 2, a hole position checking means 42 of the program 4 compares the position of a hole 12 on a circumference which is different from an index hole 11 of the medium 1 read by a hole position reading means 3, with hole position information 41 which is peculiar to the program 4. Then, when the compared result is the continuity of the execution, the execution of the program 4 is continued, and when the compared result is the stoppage of the execution, the execution of the program 4 is stopped. Thus, a program crime or an illegal use is prevented.

IPC: H01M8/04
Filed: 1990-09-28
Abstract: PURPOSE:To prevent a cooling medium from lowering in quality by making the cooling system of a fuel cell main body a closed one by which the cooling medium is separated from other systems such as a steam feed system and a water utilization system which utilizes water condensed from exhaust gas fed from the cell main body or a reformer. CONSTITUTION:The cooling system of a fuel cell main body 1 is provided with a steam generating heat exchanger 12 which utilizes the heat of the cooling system and a cooling medium tank 13.

Title: Pressure reducing valve
Inventor: YAMADA HIROSUKE
IPC: G05D16/06
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To eliminate the remaining pressure fluid in a diaphragm chamber and to secure the satisfactory flow rate characteristic at the secondary side by preparing a nozzle part to suck the pressure fluid contained in the diaphragm chamber toward a secondary port. SOLUTION: The pressure fluid supplied from a primary port 22 is partly led into a diaphragm chamber 64 from a 3rd chamber 58 via a 1st path 66 and then supplied to a nozzle hole 60 via a 2nd path 68 to generate the force to press up a 2nd diaphragm 62. Thus, the force that is generated by the pressure fluid supplied from the port 22 and presses up the diaphragm 62 counters the force of a pressure regulation spring 74. As a result, the secondary pressure applied to a fluid pressure equipment is regulated. Then the diaphragm 62 gradually moves up against the force of the spring 74, and a stem 38 and a valve body 44 move up in a single body with the diaphragm 62. Thus, the body 44 is set at its seating part 56 and the set pressure is secured.

Title: Detecting device for oil leak
Inventor: SHIMADA KOJI
IPC: G01M3/04
Filed: 1984-12-13
Abstract: PURPOSE:To detect leakage of oil automatically when an oil leaking speed is slow by providing an oil leading sensor which absorbs oil and expands, a pressure-sensitive conductive element which converts the expansion into variation in electric resistance, and an alarm in a case. CONSTITUTION:Two plate type sensor pieces 21 and 22 which constitute the oil leaking sensor 2 and the pressure-sensitive conductive element 3 are put in the drum-shaped rigid case 1 which have two parallel and opposite wall surfaces and an open periphery. When the oil leaking sensor 2 absorbs leaked oil and expands, the pressure-sensitive conductive element 3 is pressed because the upper and lower parts are constrained. The element 3 decreases in internal resistance abruptly when applied with pressure, and this is displayed as a switching phenomenon by turning on the lamp of the alarm or allowing a buzzer to sound.

Title: Kana/kanji converter
Inventor: MINEKI KOZO
IPC: G06F17/22
Filed: 1986-11-07
Abstract: PURPOSE:To automatically convert KANA (Japanese syllabary) to KANJI (Chinese character) when divided paragraphs reach a prescribed number, to convert the top one paragraph into a sentense including both KANJI and KANA and to output the sentence by referring to a KANJI pattern and dividing an inputted read character string into paragraphs. CONSTITUTION:When an operator inputs read KANA character from an input part 1 a control part 2 stores the inputted read KANA character in a temporary storage buffer by an inputted read storing-processing step 10, and shifts to a paragraph dividing processing step 20. In that step, the part 2 checks the patterns of two-and three-sound KANJIs together with the previously inputted read character string that is not KANJI-converted, and divides the input read character string into paragraphs based on KANJI pattern information. A number of paragraph check-processing step 30 checks the number of paragraphs divided in the processing step 20, and when the number exceeds two, the step 30 shifts to a converted character string generation-processing step 40. The step 40 takes the top two paragraphs out of the input read character string, and shifts to a KANA/KANJI conversion-processing step 50 in which it converted KANA into KANJI.

Title: Wiring delay adjusting circuit, semiconductor integrated circuit and wiring delay adjusting method
Inventor: KATO MASATAKA
IPC: H01L21/82
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To make the wiring delay easily adjustable by determining the on-off state of a switch capable of selectively feeding a reference voltage level to a delay adjusting line through a programmable link. SOLUTION: When delay adjusting signals ϕ1-ϕ3 are inputted to the gates of n-channel MOS transistors Q1-Q3 and selectively asserted to high level, one of delay adjusting lines 10, 20, 30 is set to the ground potential while capacitor C between a clock transmit path 17 and lines 10-30 act to delay a clock transmitted through the path 17, resulting in that the delay is max. when all the transistors Q1-Q3 turn on. By combining the signals ϕ1-ϕ3 through a switch control circuit to be a programmable link, the wiring delay can be finely adjusted.

Title: Facsimile interface device
Inventor: NIINA SHINICHI
IPC: H04N1/32
Filed: 1990-10-01
Abstract: PURPOSE:To prevent an error in the specification of format of an opposite machine and a transmission mistake from occurring by performing such control to transmit image data in a G3 format when matching is taken based on a dial-tone message replied from a line, and to interrupt a transmission operation when connection refusal due to unmatching. CONSTITUTION:A dial-tone is issued by a code of high definition layer characteristic adaptive for a G4 format assuming the opposite machine as the G4 format. The next message required for connection is returned from an ISDN corresponding to the dial- tone, and the transmission/reception of an answer in accordance with the message is repeated. An interface device checks the matching with the opposite machine in such signal transfer process. When it is judged that the opposite machine is a G4 machine, the line is connected, and transmission is performed, and MMR image data is sent out. When a message representing the connection refusal is returned, the content of the connection refusal is analyzed, and when it is judged that noncoincidence for the matching is obtained, a dial-tone operation is performed by the code adaptive for the G3 format assuming the opposite machine as the G3 machine. Thereby, it is possible to automatically perform matched connection even without recognizing the format of the opposite machine, and to prevent the connection mistake due to format unmatching from occurring.

Title: Bias impressing method
Inventor: KOBAYASHI YUICHI
IPC: G03G15/06
Filed: 1986-11-06
Abstract: PURPOSE:To eliminate ground staining at the front end part of an image by correcting a bias voltage impressed on developing rollers except the 1st one to a higher voltage while the front end part of a latent image latent image passes the developing rollers except a 1st one. CONSTITUTION:A capacitor C3 is charged with the output of a detecting circuit VD and the voltage is stored in a storage circuit M at a development time T1; and an output circuit OC determines a bias voltage corresponding to the voltage of the capacitor C3. The collector output of a transistor (TR) Q4 is generated corresponding to the input of the output circuit OC one to one and a voltage +alpha is added thereto. This +alpha is normally +40-+80V. A high voltage (+100-+200V) is impressed additionally on developing rollers 4 for a time T4 by Zener diodes Z3 and Z4. Therefore, the bias voltage impressed on the developing rollers 4 is corrected to a higher voltage until the front end part of the electrostatic latent image passes the developing rollers 4 and the induced voltage of the developing rollers by the front end part of the electrostatic latent image is detected, so a failure in applying the bias at the time of the development of the front end of the electrostatic latent image is prevented to eliminate ground staining at the image front end part.
