Title: Electronic watthour meter
Inventor: KAWAI TAKASHI
IPC: G01R22/00
Filed: 1987-09-04
Abstract: PURPOSE:To accurately detect an open phase, etc., by detecting respective line voltages and deciding the open phase and a drop in source voltage from the detection signals. CONSTITUTION:When the line voltages among feed lines P1-P3 are normal, a voltage VCC obtained by rectifying secondary voltages of transformers 1 and 3 by diode bridge rectifiers 5 and 7, a voltage Vop obtained through the rectification of diodes (Di) 15 and 17, and voltages V1-2 and V3-2 obtained through the rectification of Dis 43 and 51 are all normal, so a power failure detecting circuit 11 outputs a low-level output signals, so that inverters 39 and 41 output high-level normal signals. For example, if there is an open phase only between the feed lines P1 and P2, the secondary voltage of the transformer 1 corresponding to the line voltage between the feed lines P1 and P2 becomes 0, so the rectified voltage V1-2 of the Di 43 becomes 0 and lower than a reference voltage Vr, so the output of the comparator 23 goes up to high level. Consequently, the output of the inverter 39 falls to low level and the open phase between the feed lines P1 and P2 can be discriminated.

Title: Up-down converter for catv
Inventor: NAKAMURA TOSHIO
IPC: H04N7/10
Filed: 1985-10-03
Abstract: PURPOSE:To prevent a talk back component from occurring in an input signal string by setting a first video intermediate frequency at a specific frequency. CONSTITUTION:The input signal string from a minimum-frequency input video signal 1-1 up to a maximum-frequency input video signal 1-N transmitted from a CATV center, is supplied to a converter, mixed with a first local oscillating signal 3 optionally selected, and converted to the first video intermediate frequency 2. The said frequency is set at a frequency that exceeds a one which is made by subtracting the minimum frequency of an input video signal string from a one double of the maximum frequency of the input video signal string. The differential between the first local oscillating signal 3 and the input signal string occurs as the talk back component 4, but is out of the frequency band of the input signal string. Therefore, no complex filter circuit to decrease the talk back component is necessary.

IPC: H05K13/08
Filed: 1990-08-22
Abstract: PURPOSE:To detect an abnormal sucking or holding state in all states of electronic components by comparing it with a reference sucking state to detect the abnormal suction of the component. CONSTITUTION:In order to detect a sucking state of an electronic component 1 by a vacuum sucking unit 3, a black background 5 is annularly irradiated with a ring light 10. An image detected by a CCD camera 7 is stored as binary twodimensional image data of white and black in a memory 122. The reference image data of the state that the component 1 is normally sucked is previously stored from a reference setter 124 in a memory 126, and a discriminator 128 compares the image data of the memory 122 with that of the memory 126 in a two-dimensional manner. If the discordant amount exceeds a predetermined value, an alarm sound, etc., is output through an output unit 130. Thus, abnormal sucking or holding state can be detected in all states of the components.

Title: Optical head
Inventor: ANDOU HIDEO
IPC: G11B7/135
Filed: 1983-11-25
Abstract: PURPOSE:To increase the processing speed of reproduction signal with a compact optical head with low cost by using two photodetectors as well as a member which extracts the luminous flux reflected by an information storage medium and transmitted through a projection lens asymmetrically an optical axis. CONSTITUTION:The laser beam sent from a light source 21 is focused toward an information storage medium 27 through an objective lens 26, and this reflected light is made incident on a projection lens 30. The lens 30 consists of a spherical lens 31 and another spherical lens 32 cut partially as adhered together. Thus the lens 30 divides an incident beam into two parts. The 1st beam components 33 is irradiated to a photodetector 36 to detect a tracking shift and to read information signals; while the 2nd beam component 37 detects an out-of-focus state by a photodetector 37. The diameter of the photodetector 36 can be reduced since it condenses at a short focal distance part of the lens 30. This improves the frequency characteristics of a detection signal and increases the signal processing speed. Thus a half mirror can be omitted to realize a compact optical head with reduction of the cost.
