Title: Hermetic melt-sticking method for pipe end face
Inventor: MORI KIYOSHI
IPC: B23K9/02
Filed: 1980-12-19
Abstract: PURPOSE: To melt-stick the end face of a pipe tightly in an arbitrary shape by pressing a heat resistant cemented carbide tip to the end face while revolving the pipe at a high speed and moving the same gradually in melt-sticking the end face of the pipe tightly.  
     CONSTITUTION: A pipe 2 is mounted to a collet chuck 3 of a spindle head 5, and the center of revolution of a tool mounting rest 13 is placed in the position about 1/2 the diameter D of the pipe 2 from the end face of the pipe on the axial centerline, and the end face of a heat resistant cemented carbide tip 19 mounted to the rest 13 is brought in abutment on the end face of the pipe 2 at broad width about 2mm from about 1/2D or over. In this state, a spindle 4 is revolved at about 2,500rpm, and while the leading end part of the pipe 2 is heated red hot by the heat of friction with the tip 19, the tip 19 is rotated by the handle 12 of the rest 13, whereby the end face of the pipe 2 is plastically deformed forcibly to a spherical shape and is thereby melt stuck.

Title: Break information repeating system trespass alarm sensor
Inventor: TOMINAGA AKIO
IPC: G08B25/04
Filed: 1995-06-23
Abstract: PURPOSE: To lower the cost of an alarm system by constituting a loop, extending to an alarm center, for encoding break information of light signal for every section, and repeating the information by light emission transmission. CONSTITUTION: Sensor poles 2-6 are connected in a loop through an alarm center device 1. For example, the sensor pole 5 receives the light signal from the light emission part 11 of the opposite sensor pole 4 by a light reception part 12, detects the signal by a detection part 13, and sends it to a signal generation part 15. When the light is not cut off between a light emission part 11 and the light reception part 12, a detection signal in the form of a pulse train is outputted, but if the light is cut off, the detection signal is not outputted and a break detection part 3 detects the break state. A signal generation part 15 encodes the light signal in its section according to whether or not there is the light signal. The repeating signal time-division-multiplexes the information in mutually opposite directions in specific order and sends it to the alarm center device 1.  Consequently, the place where the light is cut off can be specified and the need to add an interface and a wire to a sensor device for every sensor pole is eliminated.

Title: Lighting device
Inventor: KOKADO KUNIO
IPC: H05B41/24
Filed: 1987-07-22
Abstract: PURPOSE:To prevent unnecessary power from being supplied to a lighting device by arranging a light receiving element for receiving light emanated from the lighting device and stopping the operation of an inverter when the output signal of the light receiving element drops to a specified reference voltage. CONSTITUTION:When an inverter 2 works to light a discharge lamp 1, the light L emanated from the discharge lamp 1 is received with a solar cell 6 which outputs a signal 6a commensurate with the amount of the light. The signal 6a, together with a specified reference voltage VR set in a reference voltage generator 7 in control circuit 3A, is inputted to a comparator 9. The comparator compares the output signal 6a with the reference voltage VR from the time point where a delay time set in a timer 8 has elapsed and determines, if the light amount of the discharge lamp 1 runs down and the output signal 6a becomes smaller than the reference voltage VR, than the discharge lamp 1 is broken or its life is close to the end, stops operation of the inverter 2 and prevents unnecessary power from being supplied to the lamp.

Title: Electrochromic element provided with heating circuit
Inventor: NIWA TATSUO
IPC: G09F9/00
Filed: 1984-08-30
Abstract: PURPOSE:To improve the response speed in low-temp. environment and to prevent dimming by providing a heating circuit which generates heat by passing electric current to a lower electrode or upper electrode which sandwiches an electrochromic layer and at least one of which is a transparent electrode. CONSTITUTION:For example, an antidazzle mirror which ECD is formed of a transparent glass substrate S on the front, thin ITO film E as the transparent lower electrode, thin film D as an oxidation colorable EC layer, thin film C as a transparent ion conductive layer, a thin film B as a reduction colorable EC layer and the upper electrode layer A in common use as a reflecting layer. Heat is generated in the electrode A when the electric current passes thereto from a low-voltage power source F via a switch SW2, level shift circuit LA and SW4. On the other hand, the heat is generated in the electrode E as well as the current flows to said electrode as well. As a result, the EC layers B, D are warmed, by which the response speed in the low-temp. environment is improved. The substrate S is also warmed and the dimming can be prevented even if the substrate S contacts with the moist and warm air in the low-temp. environment. The colored state is maintained even if the SW1, 3, 5 are turned off after the coloring.

Title: Phase locked loop circuit
Inventor: ISHIKAWA ICHIRO
IPC: H03L7/107
Filed: 1990-07-11
Abstract: PURPOSE:To obtain the phase locked loop circuit, for which pull-in is made easy even when mixing disturbance noise, by providing a means to suppress gain small at a phase comparator when a frequency component higher than a predictive frequency component is included in an external input. CONSTITUTION:When the mixture of disturbance noise is detected or estimated, the gain at a phase comparator 1 is suppressed small regardless of the function of a mode controller 4. Therefore, the output frequency of a voltage controlled oscillator does not exceed the pull-in limit because of the disturbance noise and when a frequency fi within the pull-in limit is inputted in place of the disturbance noise, pull-in is enabled. Thus, even when inputting the disturbance noise of the high frequency component to the phase comparator 1 which gain can be controlled to be increased/decreased, pull-in can be easily executed after the input.

Title: Coordinate detector
Inventor: YOSHIKAWA KAZUO
IPC: H03K17/96
Filed: 1982-10-15
Abstract: PURPOSE:To improve the sensitivity of detection and the scanning speed, by amplifying non-invertingly an output signal of a changeover switch, connecting a capacitive element between its output terminal and an input terminal of a touch detecting section to decrease apparently the capacitance at noncontact. CONSTITUTION:Impedance Z0 when viewing an input terminal of a touch detecting section TCD is expressed as Z0=V1/I1-I2 and the impedance before a capacitive canceling circuit CCL is added is expressed as Z1=V1/I1. Thus, the impedance when viewing the input terminal of the touch detecting section TCD with the capacitance canceling circuit CCL added is expressed as Z0>Z1, this shows that the impedance is increased apparently. As a result, since Z=1/omegaC, the increase in the impedance results in decreasing the capacitance. Further, in setting the amplification factor of a non-inverting operational amplifier AMP twice, the condition of the capacitor C0 is as C0<Ct, where Ct is the sum of a ground capacitance C11 of the changeover switch MPX, a compensating switch C12 and a temperature compensating capacitor C13.
