Abstract: PURPOSE:To obtain a superior cooler in the structure, wherein the cooling efficiency thereof is good, and moreover, the frost of the cooler can be also defrosted efficiently by a glass tube heater and so forth, by a method wherein fins larger than other fins are provided on the pipe at every a certain number of sheets in each stage and the larger fins are respectively brought into contact to the pipe or the fins in the adjacent stage thereof. CONSTITUTION:The longitudinal dimension Y2 of each second fin 13 for heat conduction is formed larger than that Y1 of each first fin 12 for heat conduction. Whereby the second fins 13 are made larger than the first fins 12. Then, the fins 12 and 13 are attached on a pipe 11 in a linear state leaving bending parts 11a in such a way that the second fin 13 is located between the first fins 12 at every one sheet, for example, among the bending parts 11a (equivalent to each stage in a state that the pipe 11 is being meanderingly bent). In that state, after the pipe 11 is made in such a state that the diameter thereof is expanded and the pipe 11 is securely brought into contact to the fins 12 and 13, the pipe 11 is bent from the foregoing bending parts 11a and is bent in such a way as to form a meandering form as a whole. By this way, the second fins 13 are respectively brought into contact to the pipe 11 in the adjacent stage thereof.

Abstract: PURPOSE:To prevent the generation of a black smoke, by closing an exhaust bypass valve and controlling an engine to be placed in a supercharged condition when a deceleration condition is detected on the basis of an accelerator control, so that the engine eliminates a differential delay of closing of the bypass valve in the time of acceleration after a speed change control. CONSTITUTION:An accelerator control detector 19 is provided corresponding to an accelerator pedal 20, and an output from this detector 19 is input to a driving control circuit 16. That is, a position of the accelerator pedal 20 is checked by the detector 19 at every fixed time, and a CPU22, which inputs information of the checked position, calculates a difference between the detected accelerator position and the checked accelerator position. And the CPU22, which decides an engine to be placed in a deceleration condition when the above difference obtains a negative value, inputs a deceleration signal to the driving control circuit 16. Then the driving control circuit 16, which controls each intake and exhaust bypass valve 14, 15 to be closed through each actuator 17, 18, actuates a supercharger by, for instance, introducing a new charge to a driven gear chamber 4. In this way, the engine is avoided from stopping its supercharge when a speed change control is frequently performed.

Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To obtain a stainless steel in which contact resistance is reduced by the precipitation of a Cu-enriched phase or the high concentration of Cu in the surface layer. SOLUTION: In this stainless steel sheet, stainless steel containing Cu of >=1.0 wt.%, and in which a secondary phase essentially consisting of Cu is dispersedly precipitated into a matrix in the ratio of >=0.2 vol.% is used as a base material 1, and a passive film 3 is deposited on the surface of the base material 1 other than the surface part in which the second phase 2 essentially consisting of Cu has been precipitated.

Title: Carrying system for distribution line
Inventor: NOGUCHI YOSHIRO
IPC: H04B3/54
Filed: 1985-11-29
Abstract: PURPOSE:To receive surely a signal voltage and current being transmitted by providing the matching impedance at the terminal part of a distribution line and its periphery to short-circuit the termination. CONSTITUTION:A single end of a matching impedance 7 is connected to a filter 6 with the other end of the impedance 7 connected to the ground respectively. Then the impedance 7 controls the reflection of the signal voltage transmitted from a signal transmitter 3a by short-circuiting the termination to the terminal part of a distribution line 1. Thus the standing wave phenomenon caused by the reflection of the signal voltage is suppressed. As a result, the signal voltage is never reflected at the terminal part of the line 1 and therefore the standing wave phenomenon can be evaded. The the signal voltage has no voltage node and a signal receiving device can receive surely the signals at any point.

Title: Circuit for detecting abnormality in clock oscillation
Inventor: TERASAWA TOSHIHIRO
IPC: G01R29/027
Filed: 1989-10-13
Abstract: PURPOSE:To make it possible to detect abnormal oscillation readily under the state wherein a clock oscillating circuit is assembled into a system in moving condition by counting the number of logics based on the oscillated clock signal, and outputting an abnormal oscillation signal when the count becomes the specified value or higher. CONSTITUTION:When an oscillated clock signal 1 is inputted, the oscillated signal 1 is delayed by 1/4 of a clock oscillating period in a 1/4-period delaying circuit 2. An oscillated-clock-singal-logic latching circuit 4 latches the logic of the oscillated clock signal at the falling edge of the 1/4-delayed output 3. An abnormal-time counting circuit 6 counts the number of the logic 1s based on the oscillated clock signal when the logic of the latch-circuit output 5 is 1. When the number of the times becomes three times or more, an abnormal- oscillation detection signal 7 is outputted. The counting circuit 6 does not output the abnormality at the time of the normal clock oscillation. When the abnormal oscillations multiplied by three occurs, the counting circuit 6 is operated, and the abnormality can be detected.

Abstract: PURPOSE:To stabilize optical coupling between fibers by coupling and fixing optical fibers, which are cut by the insertion of an optical control member, by pipe-shaped glass which has an internal diameter a little larger than the external diameter of the optical fibers and an external diameter a little smaller than the internal diameter of a flange part. CONSTITUTION:The optical control member 36 is inserted into the flange part 32 and the fibers 33a and 34a which are cut by the insertion of the optical control member 36 are coupled and fixed by the pipe-shaped glass 38 which has the internal diameter a little larger than the external diameter of the fibers 33a and 34a and the external diameter a little smaller than the internal diameter of the flange part 32. Then the jackets of parts of the optical fibers 33 and 34 which are inserted into the glass pipe 38 and a fitting part 31 are removed to expose the fibers 33a and 34a themselves. Therefore, the optical fiber 33 has the optical fiber 33a exposed entirely, the optical fibers 33a and 34a in the glass pipe 38 are adhered by the glass fiber, and the part of the optical fiber 34 where its jacket is not removed is adhered to the flange part 32.
