Title: After-burn preventer for engine equipped with air pump
Inventor: MURAKAMI NOBUAKI
IPC: F01N3/22
Filed: 1978-02-20
Abstract: PURPOSE: To prevent after-burn from taking place in an exhaust pipe, by detecting the acceleration or deceleration of engine and stopping the supply of secondary air to the exhaust pipe at appropriate time without delay.  
     CONSTITUTION: When a throttle valve is opened during the acceleration of engine, the boost pressure of an intake manifold 6 falls quickly and the negative pressure of a chamber 1b of an acceleration and deceleration detector A decreases but the decrease in the negative pressure of another chamber 1a is delayed by the resistance of an orifice 4. For this reason, the pressure differs between the chambers 1a, 1b and a diaphragm is pushed leftward and a magnet 8 is moved leftward. As a result, a reed type switch 9 is turned on and a solenoid 10 of an air control valve B is energized. Thereby, a plunger 11 of the valve B is pulled up, a valve part 13 shuts off a passage 15a and the secondary air 21 is all discharged from an outlet port 15b

Abstract: PURPOSE:To construct a foundation for revetment, etc., with good efficiency by a method in which formworks with half-built bottom are floated and connected  at a construction site, and as they expand, cement mortar is placed into the  formworks to settle the formworks until they are fixed to rockbed under water. CONSTITUTION:Iron bars 3 are built in the space of a water-tight hollow portion in the upper opening of formworks 1 with half-built bottom 2, and the formworks 1 are towed to a construction site and connected upwardly while being  floated by a working ship, etc. As the iron bars 3 are assembled and expanded,  cement mortar is placed into the formworks 1 to gradually settle the formworks 1. As soon as the upper part of the formworks 1 is exposed on the water  surface, cement mortar is poured through a pressure feed hose 6 into a water- proof cloth 5, etc., and thereby the water-proof cloth 5, etc., is expanded and  fixed to the rockbed under water. Then, small pebbles 12, etc., are stuffed into  the formworks 1 and then connected with the bottom 2 of the next formwork  by a connector 8. These operations are repeated.

Abstract: PURPOSE:To attain a test carried out when a drain address circuit is used at the same impressed voltage as when it is actually used by installing an inspection memory cell in the output block of a memory cell array and setting it at a writable state at the time of inspecting drain stress. CONSTITUTION:At the time of an address input terminal A1 is set to H after normal writing is performed, column decoder outputs 1X-4X become H through an X decoder 18. A Y decoder 17 sets word lines WL1-WL4 to a potential zero to attain a drain stress state. Simultaneously an input buffer 161 controls a switch circuit 21 and supplies a write voltage Vpp to the control gate of an inspection memory cell DM. In that state, the write voltage Vpp is impressed on the drain of the cell DM through a write/nowrite switching circuit 19 in accordance with a write control signal WCS. The cell DM becomes an on state, and the drain voltages of memory cells M1, M<2>... attain the same value of a normal writing action. Accordingly the drain stress can be tested under the same conditions as actual using ones.

Namely, the lid 5 is inserted in the groove-shaped recession 3 until it comes in contact with the bead core 4, and subsequently the lid 5 and the tire main body 1 are welded and stuck to each other by means of a supersonic welder 6. Thus, the lid 5 is united into one body with the tire main body 1 to eliminate a gap part and injection molding type tire 10, with the bead core 4 certainly maintained without deformation, is obtained.

IPC: H01L27/04
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To easily take the pair ratio of diffusion resistances by making parts except for a flat part to have substantially the same thickness since the flat part which is considerably approximated to recessed parts becomes slightly thin since resist flows. SOLUTION: The surface of an epitaxial layer corresponding to a buried layer 33 is set to be substantially flat and the surface of the epitaxial layer toward a separation area 34 from the buried layer 33 forms the recessed parts 35 having inclinations descending downward. The surface of the epitaxial layer 32 corresponding to the buried layer 33 is substantially flat with such constitution and the recessed parts 35 having the inclinations descending downward toward the separation area 34 from the flat part are provided. When resist 43 is applied to the part, substantially uniform film thickness is obtained in the flat part. Thus, the excess/lack of exposure time owing to the fluctuation of film thickness is suppressed even if the film is exposed by using a single wavelength and the pair ratio of diffusion resistances can easily be taken.

Filed: 1990-01-29
Abstract: PURPOSE:To obtain a coding system with high efficiency by combining a coding symbol with a correlation in plural frame time series consecutive timewise so as to form a block and assigning a variable length code to each block. CONSTITUTION:A variable code coding section 4 arranges having correlation of coded symbols 102 between equal frame on a same position on a pattern as a set among plural N frames of coded symbols 102 stored in a storage section 2 and allocates a variable length code generated based on the generation probability in the lump to obtain variable length coding data 105. When the variable length code is assigned to N frames of coded symbols 103, a storage write control section 3 is operated to be overwritten by the coded symbol 102 of a succeeding frame to the content of the storage section 2. Thus, the redundancy between frames of the coded symbols is suppressed and the coding with excellent efficiency is obtained.
