Title: Refrigerator
Inventor: AOKI TAKESHI
IPC: F25B1/00
Filed: 1988-04-15
Abstract: PURPOSE:To rapidly modify a valve opening degree and improve response characteristics of a valve with respect to the change of a signal by deciding a pulse width in a state that a calculated value is corrected by the addition or subtraction of hysteresis equivalent upon judging the transition trend of a calculated value. CONSTITUTION:An arithmetic section 21 takes an average by sampling, at ah appropriate period, signals released out of indoor temperature sensors 10 and 11 to set an indoor temperature and executes an operation by PID in relation to a preset temperature to output D data from a group D of output terminals. When a deviation between the indoor temperature and the preset temperature is large, a value becomes low, and when a deviation between them is small, a value becomes high. A counting section 22 produces a clock pulse on the basis of a reference clock outputted from the arithmetic section 21 and outputs said clock pulse as P data from a group Q of output terminals to a comparing section 29. When the frequency of a signal outputted from the comparing section 29 is set to a value approximated to the resonance frequency of a spring interconnected to the valve of a refrigerant flow rate controlling valve 14 within a range that the resonance of the spring does not occur, the hysteresis of the valve with respect to a voltage applied to the valve becomes small, and response characteristics of modifying a valve opening degree are thus improved.

Title: Data communication equipment
Inventor: IWAKABE FUYUKI
IPC: H04L1/16
Filed: 1984-05-10
Abstract: PURPOSE:To detect a case where the retransmission is impossible for a data clock where a code error is detected by sending a retransmission data block with addition of a block discrimination code from the transmission side and discriminating said data block at the reception side according to the block number and the discrimination code. CONSTITUTION:When a check code comparator 10 at the reception side detects a code error of a reception data block, a retransmission request signal transmission circuit 9 sends a retransmission request signal to a public telephone circuit 7 via a modulation/demodulation circuit 8. A retransmission request signal detecting circuit 6 at the transmission side detects said request signal. Then a transmission control part 2 reads the corresponding data out of a transmission data memory 1 and sends it again. A retransmission block discrimination code adding circuit 14 adds a retransmission block code to a retransmission data block, and a block number adding circuit 3 adds a block number preceding two steps. The retransmitted data clock passes through the comparator 10 as long as no code error is detected. When a block number detecting circuit 11 detects the same block number, a retransmission block discrimination code detecting circuit 15 decides whether or not the detected block is the retransmitted data block.

Title: Multiplex transmitter
Inventor: UCHIDA MAMORU
IPC: H04J3/14
Filed: 1994-05-06
Abstract: PURPOSE:To prevent a fault of the transmitter from being affected on the entire system by providing an abnormality detection means to the transmitter so as to open a switch provided among a reception section, a transmission section and a signal transmission. CONSTITUTION:Plural signal transmitters 2 are connected in parallel with a single transmission line 1. Each signal transmitter 2 sends transmission information from a host controller and reply information to the host controller in time division vi the transmission line 1. A control section 22 receives transmission information from the transmission line 1 via a reception section 24 and sends the reply signal to the transmission line 1 via a transmission section 25. The control section 22 has a self-diagnostic sequence sending prescribed data and receiving the data such as a loopback check or the like and sends a state signal SC of the diagnostic result to an abnormality detection section 26. When the state signal SC indicates abnormality of the control section 22, the abnormality detection section 26 controls a switch 28 provided in an internal transmission line 23 to be open. Thus, a faulty signal transmitter is disconnected from the transmission line 1.

Title: Stereoscopic picture display device
Inventor: INOUE AKIRA
IPC: H04N13/04
Filed: 1990-04-10
Abstract: PURPOSE:To easily attain the adjustment in matching with an interval of eyes in details by providing a picture display section, a correction picture display panel having a correction section moving a displayed picture and a display position control circuit moving the displayed picture onto the display panel. CONSTITUTION:A correction type picture display panel 10 consists of a picture display section 5 displaying a picture through the use of part of its display area and a surrounding correction section. A display position control circuit delays the picture in matching with the display position and sends a drive signal to a panel drive circuit 9. When a reference position is taken in the middle of the correction type picture display panel 10, a delay smaller than the standard is given to a left panel drive circuit in the X direction and a large delay is given to a right panel drive circuit to an observer whose interval of eyes is large. Moreover, the delay in the X direction is applied opposite to that above to an observer whose interval of eyes is small. Since the vertical and horizontal relative position of a display picture 5 on the correction type picture display panel 10 is changed, the adjustment in matching with the interval of eyes is realized.

Title: System for selecting repeater route
Inventor: KIMURA HIROMI
IPC: H04L45/18
Filed: 1995-04-20
Abstract: PURPOSE: To prevent a repeater packet which makes a detour from passing through a same node with superimposition by providing a passing station setting area in the transmitted packet and setting the history of a repeater node. CONSTITUTION: An exchange 2A which receives the packet PT from a subscriber 1X selects the second order route P2 so as to transmit the repeater packet PTT since the first order route P1 of a routing table is having a fault. When the repeater packet PTT is relayed, the respective packet exchanges 2A-2E sets respective node numbers 2A-2E in the passing station setting areas. A repeater exchange like the exchange 2C selects the route P5 of successive order excluding the routes P3 and P4 which are connected to the node numbers 2A and 2B which are read from the passing station setting area of the repeater packet PTT which executes reception in route selection so as to transmit PTT to the exchange 2D of a connected destination.  The exchange 2D selects the route P6 in a same way and the exchange 2E connected to the route P6 transmits not the repeater packet PTT but the packet PT to the destination subscriber 1 Y.

Title: Underfloor wiring cable
Inventor: ODAKA RYOICHI
IPC: H01B7/36
Filed: 1991-04-02
Abstract: PURPOSE:To make unnecessary wiring recognizable at a glance by applying or sticking an irreversibility indicating agent to the surface of underfloor wiring cables along the axial directions of the cables and making the indicating agent applied to a cable disconnected from equipment to work. CONSTITUTION:Irreversibility indicating heat sensitive paint 9 is applied in lines to a cable 5 along the axial direction of the cable 5. Since the paint 9 becomes discolored and maintains the discolored state when a fixed temperature state is set, the color changing temperature is selected so that the paint does not become discolored at an ordinary overload current. When the cable 5 is disconnected from equipment, an electric current is made to flow to the cable 5 so as to make the paint 5 to be forcibly discolored. Therefore, an unused cable can be visually confirmed without using any circuit tester.
