Title: Torque detecting method for boring machine
Inventor: HASHIMOTO TOSHIKUNI
IPC: E21B45/00
Filed: 1993-05-28
Abstract: PURPOSE:To dispense with the device modification of a boring machine by extracting the DC current/voltage signal proportional to the output current of an inverter, and detecting the torque of a spindle based on it for controlling the revolving speed. CONSTITUTION:An inverter circuit 10 for controlling the revolving speed of an AC main motor 1 is provided, and the output revolving speed of the main motor 1 is steplessly controlled. The inverter circuit 10 first converts the AC power source of the commercial frequency into DC power, again converts the DC power into the voltage power source of an optional frequency, and feeds it to the main motor 1, thus the revolving speed of the main motor 1 is controlled, and the revolving speed of a spindle 4 is controlled. The output of the motor 1 rotates the spindle 4 with the first belt 2A via a transmission 3, rotates a hydraulic pump 5 with the second belt 2B, and operates hydraulic cylinders 6, 6 to lift or lower the spindle 4. The torque value of the spindle 4 is calculated and displayed based on the measured values measured by measuring instruments.

Title: Mos transistor
Inventor: FUKUSHIMA YOSHIBUMI
IPC: H01L29/78
Filed: 1989-05-19
Abstract: PURPOSE:To obtain a semiconductor integrated device which is small in size and high in breakdown strength by a method wherein a high concentration impurity region is provided just under a drain. CONSTITUTION:A high concentration impurity region 7 provided to a region just under a drain 3 can be brought into contact with the drain 3 in large area without making a MOS type transistor forming region large. Therefore, when a junction between the drain 3 and a semiconductor substrate (high concentration impurity region 7) is put in a yield state, a yield current flows through the intermediary of a wide junction between them. By this setup, a yield current becomes small in density, so that thermal breakage does not occur in the junction and a small semiconductor integrated circuit high in breakdown strength can be obtained.

Abstract: PURPOSE:To promptly adjust an electrically-operated equipment to a desired position by storing information of a moving amount of the electrically-operated equipment, when it is once set to an optimum position, and reading the stored information of the moving amount even when the set position of the electrically- operated equipment is changed thereafter. CONSTITUTION:In order to adjust an electrically-operated equipment, for instance, an angle of a power-fender mirror 2, each movement switch 6a to 6d on a switch panel 4 is respectively operated. A movement command signal in accordance with switch operation is transmitted to an electrically-operated equipment control part 10 from a switch panel control part 8.

Title: Constitution of terminal of liquid crystal panel
Inventor: SHIRAKI AKISHI
IPC: G02F1/1333
Filed: 1981-08-13
Abstract: PURPOSE:To realize packing of high density, by forming at one time the electrode patterns on a sheets of panel glass and with division into matrix scan electrodes and signal electrodes and at the same time concentrating the scan electrode terminal group for connection of external input and the signal electrode group at a side of the panel glass. CONSTITUTION:For an electrode pattern, signal electrodes 15 and scan electrodes 16 are formed at one time on a panel glass 5, and the scan electrode terminals having a smaller number of pieces than the signal electrode terminals are distributed on extended terminal of the signal electrode terminal. In such a way, the upper and lower panel glasses can be used in common with each other to reduce the cost of the panel. Furthermore the connecting terminals can be distributed at two sides of the panel when a liquid crystal panel is assembled. Thus the circuit blocks can be connected to each other just by sticking two sheets of connection tape 6. This reduces the number of connecting processes down to half compared with a conentional example.

Abstract: PURPOSE:To inexpensively improve the speed and the precision of color correction processing by storing the sum total of values of a term of each stimulus value included in the result of multiplication with a coefficient matrix for color correction with respect to values which each stimulus value can take and calculating sum totals including elements of each row of the coefficient matrix out of sum totals selected in accordance with stimulus values as the color correction object. CONSTITUTION:A matrix which consists of a single column and is given by an integer- order formula whose individual elements correspond to one of plural stimulus values is multiplied by the coefficient matrix having the same number of columns as the number of elements of this matrix, thus correcting plural stimulus values. In this case, a sum total selecting means 11 preliminarily stores sum totals of values of terms of respective stimulus values included in the multiplication result correspondingly to values, which plural stimulus values can take, and selects sum totals corresponding to plural stimulus values as the correction object from these sum totals. An adding means 13 adds sum totals including elements in each row of the coefficient matrix out of these selected sum totals to obtain the multiplication result. Thus, the speed and the precision of color correction processing are inexpensively improved.
