Title: Sliding contact faces of mechanical seal in submersible pump
Inventor: TSUJIMOTO HARUO
IPC: F04D13/08
Filed: 1984-02-27
Abstract: PURPOSE:To protect the sliding contact face from solid matters, in a mechanical seal for submersible pump, by pressure feeding the air into a pressure receiving section between a fixed sealing ring and a rotary sealing ring under driving of pump thereby loosening the hermetically sealed state. CONSTITUTION:The sliding contact face 5 of a mechanical seal for a submersible pump is formed with a fixed seal ring 2 and a rotary seal ring 3 then an air pressure receiving section 6 is provided near the innercircumference. Under stoppage of pump, a push spring 4 will function to maintain the hermetically sealed state while under driving, air is fed into said section 6 to function against said spring 4 thus to weaken the hermetically sealed state and to block the solid matters such as sand contained in the external liquid off the sliding contact face 5. Consequently, the durability of mechanical seal can be improved.

Title: Optical cable for cryogenic service
Inventor: MOGI AKIO
IPC: G02B6/44
Filed: 1989-02-17
Abstract: PURPOSE:To allow stable light transmission with a lens transmission loss even at an extremely low temp. by constituting the cable by using optical fibers formed by loosely housing coated fibers coated with a UV curing type resin into metallic tubes. CONSTITUTION:The coated optical fibers 3 of the optical cable to be used for LNG storage facilities, etc., are constituted by loosely housing the optical fibers 1 primarily coated with the UV curing type resin having a good low-temp. charactersitic into the metallic tubes 2 having a low coefft. of expansion. The optical cable 8 for cryogenic service is formed by using such coated optical fibers 3. Since the shrinkage of the metallic tubes 2 is thereby lessened even under the extremely low temp., bending and side pressures are not applied on the fibers 1 and the increase in the transmission loss is prevented. Since the construction is of a loose type, the fibers 1 are kept free from the side pressures even when subjected to abrupt external forces, such as bending, at the time of cabling.

Title: Knock detection device of internal combustion engine
Inventor: KUMA TETSUO
IPC: F02P5/152
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of knock detection by providing a judgement invalid means which makes the judgement of a judging means invalid by responding to a noise component which is different from a knock component which is superimposed on ion current. SOLUTION: When noise which is accompanied by the operation of an injector is superimposed on ion current, ion current is input into a band pass filter 7 for knock and a noise detection circuit 9 from a charge amplifier 5 through a first switching circuit 6. The noise detection circuit 9 detects the noise frequency component and outputs an output signal into a second switching circuit 10. The second switching circuit 10 is operated by the output signal to open the circuit, and electrical connection between the band pass filter 7 for knock and a knock judging circuit 8 is shut off. In this way, since the judgement of knock is made invalid when noise component is superimposed on ion current, knock detection accuracy and reliability are improved.

Title: Signal processor
Inventor: WADA RIYOUICHI
IPC: H04L1/00
Filed: 1979-03-29
Abstract: PURPOSE:To obtain a signal processor which generates assuredly the Q code through the simple process, by securing the modulo 2 addition for the contents of the sequential shift register and the input data and then repeating one shift. CONSTITUTION:When first data W1 is supplied to input IN, the data is supplied to sequential shift registers 101 and 104 via modulo 2 adder 100. After the supply of data W1, AND gate circuit 103 opens to receive supply of one unit of clock CK and then to carry out the operation of matrix T. After this, AND gate circuit 103 closes, and next data W2 receives the modulo 2 addition via adder 100 along with contents R of the shift register and with every sequential bit to be then supplied. Thus gate 103 opens to carry out matrix operation T. In such way, the input and the shift are repeated up to W6 in sequence, thus obtaining the Q code to contents R of the shift register.

Title: Semiconductor integrated circuit device
Inventor: SHIMIZU GIICHI
IPC: H01L21/331
Filed: 1987-02-20
Abstract: PURPOSE:To prevent a collector current ratio from varying and therefore to keep the current ratio constant even though the concentration distribution in a base.emitter region might vary correspondingly to the forming condition. CONSTITUTION:A connection is accomplished between a first transistor 15 base constituting a current mirror circuit and a second transistor 16 base, a connection is performed between the second transistor 16 base and collector, and furthermore the first transistor 15 collector is connected with a pinch resistor 14 one end. A collector current being rendered larger, the pinch resistor value gets larger than the design value simultaneously so as to function to decrease the collector voltage of the first transistor 15. Therefore, the collector current of the first transistor is kept constant. On the contrary, a base width being larger than the design value, the pinch resistor value gets smaller so as to keep the collector current of the first transistor constant. As mentioned above, the collector current can be kept constant by means of varying the pinch resistor value notwithstanding that the forming condition varies.

Title: Altitude environment recognition device

IPC: F02D41/04
Filed: 1993-02-26
Abstract: PURPOSE:To recognize altitude environment with a high accuracy regardless of auxiliary air by correcting either one of the mass flow amount of intake air in standard altitude and the mass flow amount of real intake air on the basis of an auxiliary air amount taken in into an engine by bypassing a throttle valve. CONSTITUTION:Rotating speed of an engine is detected by a detecting means A, and the opening degree of a throttle valve is detected by a detecting means B, and also the mass flow amount of intake air in standard altitude is calculated by a calculating means C. The mass flow amount of real intake air is measured by a measuring means D. Altitude is calculated by a calculating means E on the basis of the ratio between the mass flow amount of an intake air amount and the mass flow amount of real intake air in standard altitude. In this case, either one of the mass flow amount of intake air and the mass flow amount of real intake air in standard altitude is corrected by a correcting means F on the basis of an auxiliary air amount intaked in an engine bypassing a throttle valve. It is thus possible to recognize altitude environment with a high accuracy even if auxiliary air is taken in into the engine.

Title: Fuel character detecting device of internal combustion engine
Inventor: KANAI HIROSHI
IPC: F02D41/14
Filed: 1991-03-05
Abstract: PURPOSE:To detect the character of an injecting fuel accurately. CONSTITUTION:A slippage amount of air-fuel ratio between the actual air-fuel ratio and an object air-fuel ratio is found. This slippage amount of air-fuel ratio is shown in a learning coefficient KGi (i=0-7) provided corresponding to a learning coefficient i (i=0-7). When a heavy fuel is used, the learning coefficient KGi is increased compared with the case to use a standard fuel, and when a light fuel is used, the learning coefficient KGi is decreased compared with the case to use the standard fuel. As a result, when the fuel character is changed, the learning coefficient KGi is also changed, and by finding a deviation of the learning coefficients KGis before and after the variation of the fuel character, the fuel character can be detected from the deviation. In this case, when the density of the suction air is converted, the deviation of the learning coefficient is converted even though the fuel character is not changed. Consequently, the fuel character is to be detected from the deviation of the learning coefficients before and after the variation of the fuel character, when the density of the suction air is not converted.
