Patent JP-S63201495-A (JP)
Title: Heat exchanger
Inventor: FUKUMI SHIGENOBU
IPC: F28F1/12
Filed: 1987-02-17
Abstract: PURPOSE:To improve the heat exchanging performance of fins, by a method wherein louvers are formed on the root of a fin, which is near to a tube, while corrugated recessed and projected surfaces are formed on the central flat part of the fin. CONSTITUTION:Louvers 5, 5, formed on a fin 2, increase a heat transfer rate between air and the fin as well as a ventilating resistance, therefore, heat exchanging efficiency between air and the fin is increased. Especially, the louvers 5, 5 are formed on the root of the fin 2, which is near a flat tube 1, therefore, the louvers 5, 5, provided at a part whereat the temperature of the air is high, develop heat exchanging effect between the air sufficiently, whereby the heat exchanging performance is increased. Further, the concave and convex surfaces 6 are formed on a flat part between the left and right louvers 5, 5; therefore, the heat transfer rate of the flat part is increased, whereby the heat transfer efficiency of the whole of the fin 2 may be increased. The separation or the turbulent flow of cooling air, flowing along the flat part, is promoted by the concave and convex surfaces 6 and the resistance of flow is increased. Concave and convex surfaces guide the cooling air toward the louvers 5, 5; therefore, the flow rate of the air, flowing through the louvers 5, 5 having a high heat dissipating performance, is increased, whereby the heat exchanging efficiency of the heat exchanger may be improved.

Title: Method for testing adhesion of coated film
Inventor: UCHIKAWA HIDEFUSA
IPC: G01N17/00
Filed: 1979-03-20
Abstract: PURPOSE: To perform a test of the adhesion of coated film on many samples under the same condition simultaneously and precisely by putting test pieces, each of which is given a cut in coated film, in a closed container and by deciding the peeling extent by utilying the adiabatic expansion a water vapor.  
     CONSTITUTION: The upper cover 6 is opened and the plate 1 with coated film that is previously given a cut is bound to the projection 12 with a string 11. Water is put in the pressure pot 5, the upper cover 6 is closed and secured with the lock metal 7, the valve 10 is closed and the water 13 is heated with the heater 14. When the pressure gauge 9 indicates a fixed value, the valve 10 is opened to exhaust air together with water vapor from the pot 5. Next the valve 10 is closed and the water is heated again. When the gauge 9 shows a fixed value, the heater is cut off, the valve 15 is opened at a stretch after a fixed time to drop the pressure in the pot down to the atmospheric pressure suddenly. The upper cover 6 is opened, the coated plate 1 is observed to decide the adhesion of coated film. However the test can be applied to a film of coating material that is not thermally deteriorated at temperature of the inside of the pot 5.

Title: Blow-by gas return device for internal combustion engine
Inventor: KATOU YOUJI
IPC: F02M35/024
Filed: 1979-03-21
Abstract: PURPOSE: To prevent blow-by gas containing oil gas from flowing into an air-cleaner for protecting a fuel vapor adsorbing member in the air-cleaner against deterioration by providing a nonreturn valve midway on a cleaner-air supply passage connected to the air-cleaner.  
     CONSTITUTION: When an engine is stopped for example, the fuel vapor with which a gap 6 in a float chamber of a carburetter 5 is filled is risen through an air-pipe 10 and a suction pipe 8, and adsorbed by an adsorption member 2 in a sucked air cleaner 1. Meanwhile, a crank chamber 11 is filled with the blow-by gas generated during the operation of the engine, and the gas is mixed with the cleaner-air introduced into the crank case 11 from an air reservoir 13 through a cleaner-air supply passage 14. The mixed gas is discharged into a suction passage 8' through a discharge control valve 15 and 1 blow-by gas passage 16. At this stage, the passage 14 is provided with a nonreturn valve 17, which prevents the blow-by gas from returning to the cleaner 1 when the generated amount of the blow-by gas exceeds the inflow amount of the cleaner-air.

Title: Semiconductor device
Inventor: HATTORI MASAYUKI
IPC: H01L29/423
Filed: 1988-02-15
Abstract: PURPOSE:To make the width of a channel per unit area large by a factor of two or more and secure high breakdown withstanding capacity, by forming gate electrodes into a curving line like shape and further, holding drain and source electrode-contact positions alternately. CONSTITUTION:Gate electrodes 6 are disposed into a curving line like shape in such a way that the electrode having forms of each polygon which is more than a quadrangle are in a row. Further, as a drain electrode contact 10 and a source electrode contact 9 are taken alternately from respective regions, area efficiency as the whole element can be increased double or more even though the same design rule as that of a conventional one is used. Although inductance load and the like are susceptible to destruction by allowing each contact to be formed into an island like shape, high breakdown withstanding capacity is secured by causing the surface of a drain region other than parts which are covered by the gate electrodes to be concentrated to a high level.

Title: Control method of speed change clutch in speed change gear
Inventor: ASAYAMA YOSHIO
IPC: F16H59/38
Filed: 1982-03-03
Abstract: PURPOSE:To effectively reduce a speed change shock, by changing pressure of oil in a cylinder of a speed change clutch transiently for each prescribed time. CONSTITUTION:When a car speed is increased to shift a speed change stage from a 3-speed to 4-speed, a valve 1 is controlled in a pattern gradually decreased with an on-time width while a valve 2 is controlled on and off in a pattern reverse to the above. Accordingly, a speed change clutch 3 for the 3- speed having been urged rightward transiently decreases pressure of oil in a cylinder of the speed change clutch, while a speed change clutch 4 for the 4- speed gradually increases the pressure of oil. As a result, the both clutches 3, 4 are engaged and disengaged while slipping, in this way, the speed change stage is shifted from the 3-speed to the 4-speed without causing the generation of a speed change shock.

Abstract: PROBLEM TO BE SOLVED: To provide an alarm inhibition information transfer method for high speed digital leased line service, a high speed digital leased line service system and synchronous digital hierarchy(SDH) system transmission equipment to be used therefor with which improvement in the efficiency of using a line between SDH system transmission equipment and the prevention of useless alarm generation can be made compatible. SOLUTION: SDH system transmission equipment 11 always establishes the multi- frame synchronism of 1.5M path sent from a DSU 4. When the equipment 11 detects that RINH generated by the DSU 4 has been assigned to 6M frames and sent out of the DSU 4 while the power source of the DSU 4 is turned off, the equipment 11 sends out alarm inhibition information based on the RINH by inserting the information to a previously assigned auxiliary bit in the 1.5 multi-frame which the equipment 11 generates. When the alarm inhibition information is detected out of this 1.5 multi- frame, the SDH system transmission equipment 12 generates 6M frames inserted to the bit, to which RINH is previously assigned, and transfers it to terminal station equipment 5.
