Title: Microcomputer
Inventor: ENOMOTO TOSHIO
IPC: G06F15/78
Filed: 1992-01-20
Abstract: PURPOSE:To respectively independently measure a power source monitor circuit operating voltage and the bottom operating voltage by providing a switching circuit to switch and output a power source monitor signal while being controlled by a switching signal outputted from a system control circuit. CONSTITUTION:In addition to a ROM 1, RAM 2, CPU 3 and input/output port 4 provided at the conventional microcomputer, a switching circuit 13 is provided to connect the output signal of a power source monitor circuit 8 by switching that signal through a terminal (b) to a reset signal generating circuit 9 and through a terminal (c) to a power source monitor output signal line 16 while being controlled by a switching signal 14 outputted from a system control circuit 5. When a power supply voltage VD is decreased to a certain point, the power source monitor circuit 8 is operated, and that signal is outputted through the power source monitor output signal line 16 to the outside. An LSI tester reads this signal and decides the power supply voltage at that time as the power source monitor circuit operating voltage. Since the switching circuit 13 is connected to a terminal (a) or (c) at such a time, no reset signal 10 is generated.

Title: Permanent magnet type motor
Inventor: NITTA ISAMU
IPC: H02K1/27
Filed: 1994-01-27
Abstract: PURPOSE:To reduce cogging torque and to suppress vibration, noise and fluctuation in the rotation. CONSTITUTION:A rotor core 26 has outer peripheral surface 26 formed such that the dimension of an air gap 32 between the outer peripheral surface 26a and the inner peripheral surface 22a of a stator core 22 increases gradually from a part corresponding to the peripheral center of pole toward a part corresponding to the center between poles thus setting the dimension Gb of air gap between poles two times as long as the dimension Gb of air gap in the center of the pole. Since the air gap 32 increases toward the center between the poles and the magnetic resistance increases proportionally, the flus density in the air gap becomes sparse at the part corresponding to the center between the poles and concentrates at the part corresponding to the central part of the pole thus bringing about a substantially sinusoidal distribution. This structure reduces cogging torque.

Title: Optical isolator
Inventor: KAWASHIMA HISAO
IPC: G02B27/28
Filed: 1989-01-18
Abstract: PURPOSE:To improve the insertion loss polarization dependency of the optical isolator by using parallel flat plate type birefringent materials for a polarizer and 1st and 2nd analyzers, and setting the thickness of the analyzers 1/sq. rt. 2 time as large as that of the analyzers. CONSTITUTION:The polarizer consists of rutile of 1/sq. rt. 2mm in thickness, a Faraday rotator 2 consists of (GdBi)3 grown by an LPE method, and the 1st and 2nd analyzers 31 and 32 consist of rutile of 1/sq. rt. 2mm in thickness. When the parallel flat plate type birefringent materials are used for the polarizer 1 and analyzers 31 and 32, incident light should not be parallel light and the focus position of each polarized light beam after the transmission in the optical isolator which differs in refractive index between the ordinary light and extraordinary light of the birefringent materials shifts in the direction of the optical path. The quantity of this deviation is, however, about 40mum in a coupling system in an LD module even when its image magnification is about 10 times. Consequently, the incident polarized wave dependency of the coupling loss including the optical isolator is improved.

Abstract: PURPOSE:To effectively make use of surplus energy by lifting a weight up by the use of surplus energy as a power source so as to be stored as potential energy, lowering the weight as required, outputting kinetic energy at the time so as to be converted into rotating motion at high speeds, and thereby generating electricity. CONSTITUTION:When a weight 2 is located at the lower position, both an electric motor 1 and an electromagnetic brake 4 are energized by surplus current so that the electric motor 1 is thereby rotated with the brake released. This thereby causes a take-up drum 10 to be rotated via a weight lifting device 3 which is composed of gears 8a, 8b... small in diameter and of gears 9a, 9b... large in diameter so as to be combined together, so that the weight 2 is lifted up with a wire 11 taken up. When the weight 2 comes up to the uppermost position, current is interrupted so that the electromagnetic brake 4 is brought into a braking condition. When it is detected that electric power is demanded to a great extent, the brake is released with the electromagnetic brake 4 excited, and a generating set 7 is rotated at high speeds through a power converter 6 with the take-up drum 10 rotated as the weight 2 is lowered down so that electricity is thereby generated.

Title: Method for detecting s/n ratio of television video signal
Inventor: IZUMI YOSHINORI
IPC: H04N5/21
Filed: 1995-01-23
Abstract: PURPOSE: To enhance accuracy in the detection of S/N ratio of video signal. CONSTITUTION: When the S/N ratio of television video signal is detected, an input television video signal is divided, on a screen, into a plurality of small blocks through blocking operation 1. For each pixel in each small block thus divided, the difference 4 between the video signal and a signal 2 averaged in the direction of time axis within each small block and/or the difference 5 between the video signal and a signal 3 averaged two-dimensionally within each small block is determined. The significance of the difference is then determined 6 by comparing the distribution of the difference with a statistical noise distribution prepared previously for the purpose of detection of S/N ratio. When a significant difference is determined for a small block, the S/N ratio of that block is employed.  The comparison is repeated sequentially over the entire screen by S/N ratio integration processing 7 and the frequency of such S/N ratio is determined over the entire screen by histogram generation processing 8. Finally, an effective S/N ratio is detected from the frequency distribution through an S/N ration decision processing 9.

Abstract: PURPOSE:To speed up recording operation for each line by deciding the picture element state of a block and omitting the recording of a block whose lines are all white when block division processing is performed at the time of recording image data of one line. CONSTITUTION:When memory cells #1-#4 of a shift register circuit 1 are all in a white state and shift specification on a signal line 31 is at low level, a decision circuit 2 holds the decision output on a signal line 31 at high level. Picture elements B1-B4 are shifted and then a recording circuit 3 records one block. At this time, the decision circuit 2 detects the memory cells #1-#4 being all white to hold the decision output on the signal line 21 at the high level, specifies a parallel shift for the shift register circuit 1, and informs the recording circuit 3 that the next block is all white. The recording circuit 3 on receiving the report of the all-white block completes the recording of the current block without recording.
