Title: Controlling method for pwm converter
Inventor: KINOSHITA SHIGENORI
IPC: H02M7/12
Filed: 1986-03-12
Abstract: PURPOSE:To prevent main transformers from being multi-split, by applying specified phase difference to a carrier wave used for controlling the pulse width modulation of a PWM converter on each car body for composing a train. CONSTITUTION:The driving car bodies of (m) units composing a train are equally divided into K groups. Within each group, a unit converter is controlled by the same PWM control signal. Accordingly, PWM controllers consisting of modulated wave signal generating sections, carrier wave generating sections, and comparison sections for comparing a modulated wave with a carrier wave can be used in common. Between the groups, each modulation signal of the modulated wave signal generating sections are of the same phase, but each carrier wave signal of the carrier wave signal generating sections is shifted positionally and mutually by specified phase. As a result, the secondary windings of main transformers T1-Tm at respective power source units can be prevented from being multi-split, and equivalent jamming current can be reduced.

Filed: 1990-03-06
Abstract: PURPOSE:To measure surface potential in both polarities even in the case of using a potential measuring means for a single polarity by shifting a reference potential impressed on the earth terminal of the potential measuring means to a reversed polarity side to the surface potential to be measured, measuring the surface potential to be measured in the range of both polarities, positive and negative, and calculating the surface potential of a photosensitive body. CONSTITUTION:A potential to be detected Vin which is detected by an electrometer probe 5 is inputted in an electrometer PCB 9 in specified timing. Since voltages +30V and +5V are respectively impressed on a power source input terminal (Vc) and the earth terminal in the electrometer PCB 9, the potential to be detected Vin is obtained in the range of both polarities, positive and negative. The potential to be detected Vin is reduced by a constant in the electrometer PCB 9 and a detecting potential V0 is obtained. In a microcomputer CPU 11, the detecting potential V0 is converted in V=-200(V0-5)+5 and the surface potential V of the photosensitive body 1 is measured. Thus, the surface potential of the photosensitive body having both polarities is measured by using the electrometer for single polarity.

Title: Multibeam antenna controller
Inventor: NAKAJIMA KATSUJIROU
IPC: H01Q3/20
Filed: 1985-03-18
Abstract: PURPOSE:To automatically prevent variations in the directing position of a multibeam antenna regardless of any missing in a beacon signal, by switching the position error signal over to zero to form a speed loop when the received level signal comes outside a proper range to drive the multibeam antenna. CONSTITUTION:When the received level signal 2 is within the normal range, as a comparator circuit 10 outputs no inhibit signal 11, a switch 12 is as illustrated and a multibeam antenna 2 is driven by a position error signal 5. In case some missing such as instantaneous interruption occurs in the beacon signal 1 for some reason or other and the signals 8 comes outside the proper range, the circuit 10 outputs a signal 11. With the signal 11, the switch 12 is changed over to zero the signal 1, allowing a signal 1 to stop the antenna 2 at the normal position. Afterward, when the signal 1 returns to the normal, the signal 11 is released to restart normal operation. Thus, the variations in the directing of the antenna 2 can be minimized regardless of instantaneous interruption of the signal.

Title: Pattern recognition pretreating circuit
Inventor: FURUI YOSHIYUKI
IPC: G06K9/36
Filed: 1985-03-18
Abstract: PURPOSE:To effectively and easily carry out a pattern recognition even to a filter in which a black point contacts an external periphery of an electrode by disposing a linear filter capable of changing the number of bits in accordance with size of the black point on the electrode and feeding a binary coded image to a pattern recognizing section. CONSTITUTION:When only 4 bit selecting signal of a CPU control input 8 is brought to a L level, a binary coded signal to which 1st bit output of (n) bit shift register 2 is inputted synchronizes with a clock pulse and appears as it is. In a 4th bit output, since the 4 bit selecting signal is L level, the same signal is produced in an OR circuit. An output of the OR circuit in an output of (n)-5th bit is H level, so that an output of (n-2) input NAND circuit 5b is influenced by the 1st bit or the 4th bit, and when both the bits are H, the output becomes L. This means a 4 bit linear filter and when bits of a right end and a left end of the 4 bits are white, 2 bits in a center are made white. With respect to the filter in which a black section 22 is present on a white electrode 20, a form is simplified and a pattern recognition is easily executed done.

Title: Device for measuring thickness of work piece in lapping plate
Inventor: KATAGIRI KIYOO
IPC: G01B7/00
Filed: 1981-04-10
Abstract: PURPOSE: To obtain the indirectly measured value which is close to an actually measured value and to alleviate the checking work, by detecting the distance between the  flat plates when upper and lower flat plates are rotated one time and returned to the  original position, compensating the distance by a computer, and computing the thickness of the work piece.  
     CONSTITUTION: The signal from a position signal transmitter 17 attached to the lower  flat plate 2 is detected by a position sensor 16 attached to the upper flat plate 1 when  the upper flat plate 1 and the lower flat plate 2 are relatively rotated one time and  returned to the original position. At this time a distance detecting sensor 15 outputs  the signal corresponding to the distance between the upper and lower flat plates 1 and  2. The computer 18 subtracts the thickness of a slurry layer of grind stone particles  between each lapping surface of the upper and lower flat plates 1 and 2 and the work  piece 3, adds the reduction of the lapping surface of the upper flat plate 1, and computes the thickness of the work piece 3. Therefore the value close to the acutally  measured value which is not affected by the irregularity of the lapping plates 1 and 2,  vibration, and the like can be obtained. Since it is not required to take out the work  piece 3, the detecting work is alleviated.
