Abstract: PROBLEM TO BE SOLVED: To prevent a non-operation of a four-way valve caused by a short- circuit between a high pressure side and a low pressure side of an outdoor unit when switched from heating to defrosting in an air conditioner having the unit with two four-way valves. SOLUTION: As a refrigerant route, an outdoor unit 5 is branched at a discharge side of a compressor 6, a four-way valve 10-1, an outdoor heat exchanger 7-1, an outdoor expansion valve 12-1 are sequentially connected to one side, and a four-way valve 10-2, a outdoor heat exchanger 7-2 and an outdoor expansion valve 12-2 are sequentially connected to the other. The unit 5 is connected from the valves 12-1, 12-2 to the unit 5 through liquid side piping 18, returned from the indoor unit to the unit 5 through a gas side pipeline 17, branched, the valve 10-1 is connected to the one via a check valve 70 of a forward flow, and the valve 10-2 is connected to the other. Thus, the refrigerant is sequentially fed when defrosted or fed reversely when heated.  The valve 10-2 is switched ((c) to (a)) when a difference between output and suction pressures of the compressor 6 is a given value or above when stitched to defrosting, and the valve 10-1 is switched ((a) to (b)) after the gas side pressure of the exchanger 7-2 is raised to avoid a non-operation (d).

Inventor: YOKOYAMA YASUMASA
IPC: G03G15/00
Filed: 1984-11-29
Abstract: PURPOSE:To prevent the generation of the blur of an image by providing two conveying rollers just near an exposing part in addition to upper stream side and down stream side conveying rollers and releasing the grasping pressure of the upper stream side conveying rollers before photosensitive paper arrives at the exposing part. CONSTITUTION:The photosensitive paper 12 is conveyed by the upper stream side conveying rollers 15, 16 and the down stream side conveying rollers 18, 19 by means of the 1st driving motor 13. An original platen 23 is moved and the 1st and 2nd exposing part conveying rollers 29, 30 in proximity to the exposing part 28 are rotated in synchronization with the platen 23 by the 2nd driving motor 20. The paper 12 is conveyed 16, 15 when the operator starts the motor 13 by pushing a button not shown. The passage of the paper 12 is then detected by a detector 40 and a motor 20 is started after the lapse of prescribed time. A solenoid 41 is energized to release the paper 12 from the roller 15 before the paper 12 arrives at the exposing part 28. The paper 12 is conveyed in synchronization with the platen 23 by the rollers 20, 30. The influence of the other rollers on the paper 12 is thus eliminated and the blur of the image is prevented.

Title: System for measuring total flow rate of multiple piping
Inventor: KUNIYOSHI TOSHIHARU
IPC: G01F1/00
Filed: 1986-10-23
Abstract: PURPOSE:To suppress the variation in a total flow rate to a low level, in adding the flow rate information detected by the flow rate sensor of each piping, by removing the max. and min. values from said information. CONSTITUTION:The flow rates of four pipings A-D are detected by sensors A-1-D-2 to obtain signals A1-D2 and CPU 4 rearranges said signals in order of magnitude to set S(1)>=S(2)>=...>=S(8). Now, when A1 A2...D1 D2 and S(1)=A1, S(2)=A2...S(8)=D2 are formed, because of four pipings, a total flow rate S=S(4)+S(5)+S(2)+S(7)=B2+C1+A2+D1 is calculated. When the signal A2 largely falls, S(8)=A2 is formed and S=S(4)+S(5)+S(2)+S(7)=C1+C2+B1+D2 is calculated. Since the diameters of the pipings are same and A1 A2 ... D2 is formed, the flow rate S becomes an almost equal value. By this method, at the time of the trouble of a certain sensor, the detection value thereof is removed and the stable total flow rate always almost constant can be obtained. Even when the number of the pipings are odd, S is calculated according to a predetermined calculation formula and an almost constant value is obtained.

Filed: 1994-10-17
Abstract: PURPOSE: To secure the nice looking and a comfortable feel, and prevent the breaking or coming off of short fibers caused by rubbing by sticking short fibers inclinedly in the irregular direction on the surface of a base material. CONSTITUTION: A large number of short fibers 16 are stuck at a specified angle of inclination with an adhesive layer 14 on the surface of a base material 12. When a coin 18 is housed on the inside and vibration is applied, since the coin 18 is capable of sliding and moving on the short fibers 16, resistance of the coin 18 to the short fibers 16 is small, and the breaking or coming off of the short fibers 16 caused by rubbing of the short fibers 16 with the coin 18 can be prevented. Since a large number of short fibers are stuck in the irregular direction, a shade of color caused by different looking direction is not produced, and appearance is enhanced.

Title: Semiconductor device and manufacture thereof
Inventor: WAKAMIYA WATARU
IPC: H01L21/3205
Filed: 1988-10-05
Abstract: PURPOSE:To reduce a stepped part to be produced when a conductive film is formed and to prevent an electrode material from remaining at the stepped part when a gate electrode of a transistor is formed by a method wherein the conductive film used as a shield is arranged in a recessed part formed in an element isolation region in a semiconductor substrate. CONSTITUTION:A conductive film 9 composed of polycrystalline silicon is deposited on a whole face. The conductive film 9 is formed to be sufficiently thick so as to fill a recessed part 7; then, a resin coating 10 composed of, e.g., a resist is deposited in order to flatten the surface. In this case, since the conductive film 9 is formed in the recessed part 7 formed in a substrate 1, a protruding size from the substrate 1 in this part during a process to form a gate electrode 12 can be suppressed to a sufficiently small range even when a thickness including insulating films 8, 11 is set to a required value; it is possible to nearly eliminate a residue of an electrode material in the process. Thereby, it is possible to form a field-shielding interelement isolation structure where a high stepped part is not produced.

Filed: 1987-10-07
Abstract: PURPOSE:To always record data on the correct position of a tape by changing the reading-out timing of a memory in accordance with a pulse phase obtained from a means to detect cylinder revolution information. CONSTITUTION:The speed of revolution and the phase of a cylinder is detected by a tack pulse detector 14. On the other hand, a synchronizing, circuit 15 detects a vertical synchronizing pulse (field circumference) and a cylinder motor control circuit 17 controls the revolution of a cylinder motor so that the phase difference between the detected tack pulse and the vertical synchronizing pulse is constant. The output timing of a data blocking circuit 11 is controlled by the cylinder revolution information detected by the tack pulse detector 14. Consequently, the output timing of the data can be changed in accordance with a cylinder jitter and the timing that a head scans a track on the tape can be made coincident with the output timing of the data. Thus, the data are recorded on the regular position on the tape track.

Filed: 1987-10-07
Abstract: PURPOSE:To execute smooth discharge of remaining pig iron in a short time by pressurizing the interior of a furnace after checking charged material at the time of coke displacing operation toward the end period of blow down operation. CONSTITUTION:In the blast furnace having e.g. 3,500m<3> inner vol., at the time of stopping ore charging toward the end period in the blow down operation, powdery material 8 having high gas penetrating resistance (e.g. sand, coke powder, water granulation slag having <=2mm grain size) is charged in upper part of lump coke 7 at the prescribed thickness (e.g. 2-5m). After that, the lump coke 7 is charged in the prescribed thickness (e.g. >=3m). Under this condition, after boring new pig iron tapping hole 3' downward toward the remaining pig iron with a boring machine for tapping pig iron so as to be deeper than the usual pig iron tapping hole, the inner part of the furnace is pressurized at the pressure (e.g. 2-4kg/cm<2>) higher than the usual blowing pressure at the time of blow down from tuyere. Then, the molten pig iron is discharged from the pig iron tapping hole 3' by this pressure to make the remaining pig iron as little as possible.

Filed: 1989-09-29
Abstract: PURPOSE:To improve the running stability of a mobile body by setting a slack of a cable in a direction at a right angle to a guide direction of a guide member. CONSTITUTION:A slack is given to cables 2, 3, 4 by taking a movable range of guide rails 5, 6 of a mobile body 1 as guide members into account.
