Patent JP-S58196722-A (JP)
Title: Da converter
Inventor: FURUKAWA YASUO
IPC: H03M1/74
Filed: 1982-05-12
Abstract: PURPOSE:To average variance in resistance value and to obtain a high-precision conversion output, by comparing a section of a ladder network with variation in input digital value and replacing it at a sufficiently high speed. CONSTITUTION:The ladder network connected annularly is disconnected by one of disconnection switches S9-S16 to constitute a current-mode ladder network D/A converter at this time. The disconnection switches S9-S16 which turn off shift successively, so the ladder network also rotates starting at one section L1 up to a section L8 successively and a weight current is also switched successively. Changeover switches S25 and S32 corresponding to an input digital value are also switched successively and synchronously. Then, the output of an output terminal 18 is averaged by a smoothing circuit 26 to average an analog output due to variance in resistance between the sections L1-L8. Further, this process is applicable to a voltage ladder network type D/A converter.

Title: Angle sensor
Inventor: MASUDA SUMIO
IPC: G01D5/347
Filed: 1984-04-24
Abstract: PURPOSE:To widen a linear region and to prevent the change in detection accuracy caused by environmental temp., by using a photoconductive cell having two photosensitive parts having equal characteristics and connecting said photosensitive parts so as to negate the change in a resistance value by the change in temp. CONSTITUTION:A photoconductive cell 9 having a fan shaped light blocking plate 10 having an angle 2phi has photosensitive parts 13a, 13b connected between electrodes 12a, 12b in series and said photosensitive parts 13a, 13b are arranged in symmetric relation to a semi-circular notch 14. Light emitting elements 15a, 15b uniformly irradiate the cell 9 when the light blocking plate 10 is absent but, when the light blocking plate 10 is revolved, one photosensitive part of the cell is increased in light blocking quantity and the other one is reduced in light blocking quantity. When two photosensitive parts 13a, 13b are connected so that the changes in resistances due to the change in temp. are mutually negated, the potential of an electrode 12c is proportional to the shift angle theta of the light blocking plate 10 and receives no influence of the change in temp. and, therefore, voltage stable to the change in temp. can be obtained.

Title: Refrigeration cycle controller and refrigeration cycle control method
Inventor: NAGAI HIRONORI
IPC: F24F11/02
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To reduce refrigerant noise incident to switching of a four-way valve by providing a control means for stopping a compressor by decreasing the operational frequency thereof when a switching is made from heating operation to defrost operation or from defrost operation to heating operation. SOLUTION: An air conditioner 10 comprises an indoor unit 11 having a heating circuit 11a and an electronic expansion valve 11b, and an outdoor unit 12 having a compressor 12a, a four-way valve 12b, a cooling circuit 12c, and a control section 12d. The electronic expansion valve 11b is set with a heating operation opening during heating operation and set with a defrost operation opening during defrost operation. The four-way valve 12b is switched to the heating circuit 11a during heating operation and switched to the cooling circuit 12c during defrost operation. The control section 12d does not stop the compressor 12a immediately upon transition from heating operation to defrosting operation but stops the compressor after lowering the operating frequency thereof to the lowest frequency. The compressor is controlled similarly when a transition from defrosting operation to heating operation. Since pressure difference is suppressed, switching noise of the four-way valve 12b is lessened.

Abstract: PURPOSE:To miniturize the electronic equipment and to reduce its cost. CONSTITUTION:A display means in a display case 11 and an image output means in a main body case 12 are connected by a sheet-like flexible cable 24 having a wiring pattern, and this flexible cable 24 is wound round spirally between a fixed part of the display case 11 side and a fixed part of the main body case 12 side. Accordingly, a motion of the flexible cable 24 which follows turning of the display case 11 is limited only in a space occupied by the spiral wound-round part, therefore, its cable 24 can be contained in a compact space and the device can be miniaturized. Moreover, since its cable can be made with a simple wiring pattern, its manufacturing cost can be reduced remarkably.

Abstract: PURPOSE:To prevent a printed board other than the printed board to be drawn out from being drawn to erroneously in the case of inserting and drawing out the printed board in the course of applying electric current at the time of the active circuit maintenance. CONSTITUTION:A printed board 1 which can maintain an active circuit to be drawn out is displayed on a display unit 15 by a fault/detachment display circuit 16, and also, applies a signal SG2 of a logical value 1 of the fault/ detachment to an erroneous drawing-out deciding circuit 20. When an operator comes into contact with an inserting/drawing-out fixture combined with a contact detector 18, a signal SG1 of a logical value 1 is applied to the erroneous drawing-out deciding circuit 20 from a contact detecting circuit 19. The erroneous drawing-out deciding circuit does not output a signal SG3 even if the logical value of the SG1 becomes '1', when the SG2 is the logical value 1, but outputs the SG3 and operates an alarm 3, when the logical value of the SG1 becomes '1' when the SG2 is logical value '0', and warns the contact with other printed board than that which is to be drawn out.

Title: Method for freezing large sized fish
Inventor: KANAO HIDETOSHI
IPC: F25D9/00
Filed: 1988-04-02
Abstract: PURPOSE:To freeze a fish quickly for improving the quality of frozen fish by freezing the surface layer of the fish by brine cooling, and then carrying out freezing of the central part of the fish and decreasing the temperature of the entire body of the fish down to an aimed temperature by air cooling. CONSTITUTION:The surface layer of a fish, 1/20-2/3 of the fish in weight, is frozen by brine cooling which is highly efficient in freezing the surface layer, and then the entire body of the fish is frozen and cooled down to an aimed temperature (-60 deg.C) by air cooling. As a result, the freezing load of the surface layer that occupies a large part of the total freezing load is quickly carried out by brine cooling which is highly efficient due to the relationship between the surface area and the distance, resulting in a large decrease in the load for air cooling and avoiding the fish from deforming because of its frozen hard surface layer. Freezing of the central part and cooling of the entire body to an aimed temperature are carried out by air cooling, that allows a higher differential temperature to perform efficient freezing of the central part than in case of brine cooling. Consequently, the total freezing efficiency is very high.

Abstract: PURPOSE:To eliminate leakage of liquid, by feeding a liquid in one container under pressure by a pressurized gas while receiving the liquid returned from a load into the other container, and eliminating mechanical parts subjected to friction. CONSTITUTION:A container 1 is used as a container for receiving liquid returned from a load. In the state that stop valves V2, V4, V5 and V7 are closed and stop valves V1, V3, V6 and V8 are opened, liquid returned from the load is carried into the container 1 via the valve V3. On the other hand, a pressurized gas is introduced into another container 2 via the stop valve 6, so that pressure in the container 2 is raised. Here, since the liquid is carried to the load under pressure via the valve V8 and a pressurized conduit 2b, mechanical parts subjected to friction can be eliminated and production of foreign matter can be avoided. Therefore, it is enabled to eliminate the leakage of liquid.
