Title: Electronic refrigerant compression device
Inventor: HAI EITON
IPC: F25B1/00
Filed: 1990-04-23
Abstract: PURPOSE: To smoothly circulate a refrigerant through a refrigerating cycle, by installing a solenoid valve to be opened or closed by control with a microcomputer on the side of a discharge port of the refrigerant and a check valve on the side of an inflow port of the refrigerant to prevent the backflow of the refrigerant. CONSTITUTION: Two or more of compression parts 1, 1A and 1B for heating and cooling a refrigerant are linked in parallel and the number thereof is optionally adjusted according to a compression force of the refrigerant. When compressing the refrigerant, a microcomputer controls an initial load 11 of the compression part 1 to generate heat, and the refrigerant stored in a cylinder body 10 and a refrigerant pipe 12 rises in pressure. In this process, check valves 16 and 17 are installed on the side of an inflow port of the refrigerant of the cylinder body 10 and the refrigerant pipe 12 to prevent the backflow of the refrigerant, and solenoid valves 14 and 15 to be controlled by the microcomputer are installed on the side of an outflow port of the refrigerant, so that the solenoid valves are kept closed to move the refrigerant in the cylinder body 10 and the refrigerant pipe 12.  The refrigerant continuously stored is heated by heat generated from the initial load 11 to raise a pressure. This prevents the backflow of the refrigerant, thereby enabling smooth circulation through a refrigeration cycle.

Title: Domestic branch of exchange
Inventor: HARUNA MASAMICHI
IPC: H04Q3/58
Filed: 1992-04-27
Abstract: PURPOSE:To allow a caller to transit to the maintenance state without need of the operation by the user when an ISDN lane is used. CONSTITUTION:A maintenance personnel of a domestic branch of exchange 11 registers in advance its own telephone number to a caller number storage section 16. When the maintenance for the private branch of exchange 11 is controlled remotely by using an ISDN line 12, a call control section 14 recognizes a maintenance request at the arrival of a call by having only to inform its own caller number through the ISDN line 12 and the maintenance state is transited without giving any notice onto the user of the private branch of exchange 11.

Title: Dynamic focus circuit
Inventor: SUZUKI MANABU
IPC: H04N3/26
Filed: 1990-04-25
Abstract: PURPOSE:To adjust the focus so that the focus is adjusted at all parts on a display screen by applying an output from a clamp circuit clamping a tip of a parabolic wave output at a focusing DC high voltage to a focus electrode to control the focus. CONSTITUTION:The focus is matched at a center position on a display screen by varying the resistance of a variable resistor 16 so as to adjust a static adjustment voltage ES in a focus control voltage. Then a voltage of a vertical parabolic wave signal inputted from a terminal 17 to adjust the vertical adjustment voltage EY thereby matching the focus of an upper end position PU and a lower end position PD on a longitudinal center line LV of the display screen. Since the focus control voltage in this case is subject to so-called bottom clamp by using an adjustment voltage ES at a clamp circuit 30, even when the vertical adjustment voltage EY is adjusted, the focus at the center position PO is kept in matching. Thus, a defect of out of focus at other position after the adjustment while focus adjustment is implemented is avoided.

Abstract: PURPOSE:To substantially generate an operation program for a robot and to improve the versability and calculating speed of a program editing device by converting coordinates on the display of the program editing device into cylindrical coordinates which prescribes wrist parameters regarding the operation of the end effector of the robot. CONSTITUTION:The CRT coordinates (X1, Y1) on the color display is converted into general two-dimensional orthogonal coordinates. In general, coordinate conversion from the general coordinates (X2, Y2) to robot orthogonal coordinates (X3, Y3, Z3) is performed. Then the tilt angle thetar of the tip of a welding torch 42 is corrected. Then the direction deviation angle thetagamma of the welding torch is corrected. Then an offset component r0 originating from that the offset r0 of the welding torch 42 is not zero actually is corrected. Thus, the conversion to the cylindrical coordinates regarding the wrist parameters for prescribing the actual operation of the robot is performed. Thus, the coordinate conversion from the coordinates P(x1, y1) on the color display to the cylindrical coordinates P(r7, theta7, d7) regarding virtual wrist parameters of the robot is performed.

Title: Grinding device
Inventor: SHIMIZU KAORU
IPC: B24B37/02
Filed: 1982-06-23
Abstract: PURPOSE:To grind a workpiece automatically and efficiently, by making a distance between the curved surface of the workpiece and the rotative center of a disk constant all the time in a state that a resin film disk is bent by a specified extent and comes into contact surface-to-surface with the curved surface of the workpiece. CONSTITUTION:Plural pieces of laminated resin disk sheets 8 are brought into contact with a curved surface 1A on a die 1 as its end comes into surface-to- surface contact at a specified amount of bending. A signal is transmitted to each of pulse motors 19 and 20 and both an X table 18 and a Y table 22 are driven to the extent of a specified amount whereby the curved surface 1A is set in reciprocating motion to the sheet 8 along the symmetrical center line so as to cause a relative distance between the rotative center of the sheet 8 and the curved surfece 1A to become constant all the time. In this way, an accuracy of the shape of the ground surface can be thus improved.

Title: Optical recording medium, tilt detector, optical disk device tilt detecting method and tilt correcting method
Inventor: ITAKURA AKIHIRO
IPC: G11B7/24079
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity of a complex tilt detecting mechanism by providing a land section or groove section adjacent to each other in both sides of each of a plurality of positions of two tracks with a portion where the center line of a track direction is displaced. SOLUTION: A position detection circuit detects a tilt detecting position P by means of a data signal obtained from an optical head and notifies it to a tilt detection circuit. This tilt detecting position P displaces the center position of only a groove G or a land L in both sides of a traveling track 7 and changes the space frequency of the traveling track. On the other hand, a tilt correction circuit corrects, on the mirror surface of an optical recording medium, a tilt amount detected by the tilt detection circuit based on a tracking error signal outputted from a tracking error detection circuit. An offset amount proportional to the detected tilt amount is forcibly corrected by an off-track correction circuit and thus, even when there is tilting, the center of spot intensity is maintained around a track.

Title: Vehicle-cruise control system and radar equipment thereof
Inventor: STOVE ANDREW GERALD
IPC: G01S13/931
Filed: 1993-05-10
Abstract: PURPOSE: To obtain a radar system from which the problem of range Doppler coupling and complication is solved by using a FMCW radar system. CONSTITUTION: A radar system 30 which determines the range of a target moving relatively to the system 30 at future time incorporates an RF source 56 for supplying signals having a frequency which increases with time at a rate of (r) Hz/s from a base frequency (f) Hz against a sweeping period ds. When the signals are transmitted, signals reflected from the target are mixed 38 with a part of the transmitted signals and signals having a frequency which is proportional to the range of the target is obtained. The source 56 has a sweeping rate (r) which is equal to the quotient obtained by dividing the base frequency (f) by time (t) (s) and the time (t) is the delay time until the target enters the measured range. Thus the predicted range of the target is obtained without making any complicated compensation on the relative speed.  The system 30 can also supply speed feedback without requiring any excessive circuit.
