Title: Electric discharge lamp lighting device
Inventor: YAMAZAKI HIROYOSHI
IPC: H05B41/392
Filed: 1988-09-28
Abstract: PURPOSE:To cause it to stably light an electric discharge lamp by performing intermittent movement while repeatedly stopping the output of an invertor, and setting the intermittence of power supply to a length of time within a predetermined limit. CONSTITUTION:The output of the device is produced when a counter 95 reads a predetermined clock pulse number as a switch 100 is on, then the single multi of a time limit circuit 96 is triggered so that the switch elements 2a, 2b of the invertor stop their movements for a predetermined period t of time, during which an electric discharge lamp 5 is turned off. The output of the electric discharge lamp can be controlled by varying the set time of generation of signals by the time limit circuit 96. While power is intermittently supplied to the electric discharge lamp 5, the intermittence of the power supply is short if its lighting frequency is high, so that the amount of ions remaining is large enough to enable the power supply to be initiated simply to light the lamp at the next cycle, whereas if the intermittence of the power supply is long the ions are eliminated so that when the lamp is lighted at the next cycle undesirably high voltage peaks are generated at the electric discharge lamp. In order to remove the effects undesirable for stably lighting the electric discharge lamp, the intermittence of the power supply is set to a proper length of time.

IPC: H04M11/06
Filed: 1983-12-23
Abstract: PURPOSE:To make more replete composite mail service by using voice information service together with other service functions. CONSTITUTION:When a terminal transmits an FAX picture, a mail service controlling section 4 judges whether the terminal requests voice information service or not. In the case where request setting for voice information service is made, information of objective terminal is examined at the time of exchange transmission of the FAX information. When the objective terminal is making refusal setting for receiving voice information service, the FAX picture is transmitted as it is. Needless to say, other service functions can work even at this time. When objective terminal does not refuse receiving of voice information service, telephone terminal provided corresponding to the objective terminal is called. Information service is made by voice to the replier to the effect that an FAX picture (mail information) will be sent. At the same time, above-mentioned FAX picture is transmitted.

Filed: 1990-09-13
Abstract: PURPOSE:To improve production yield by forming a gate electrode on a flat low concentration layer whereto recess etching is not carried out and by deciding a thickness of a channel formed below the gate electrode depending on a thickness of a high concentration thinned layer. CONSTITUTION:A device is provided with a high concentration thinned layer 23 containing impurities at high concentration, a flat-surface low concentration layer 24 which is formed on the high concentration thinned layer 23 and composed of the same material as the high concentration thinned layer 23 and which contains impurities of low concentration or contains no impurities, a gate electrode 30 and an ohmic electrode formed on the flat low concentration layer 24, and a high concentration layer which is formed self-matchingly to the gate electrode and contains impurities at high concentration. Therefore, it is possible to prevent element characteristics from varying based on irregularities in recess etching and to improve production yield. Furthermore, since each layer of an FET is composed of the same material, a layer of good controllability and a simple structure can be acquired. Since the high concentration layer is formed self-matchingly to the gate electrode, a source parasitic resistance is reduced.

Filed: 1983-12-26
Abstract: PURPOSE:To obtain a composite material having high press sticking strength at a good yield by specifying the roughness of joint surfaces in a process for producing the composite material by press sticking the different materials to each other. CONSTITUTION:A base metal and a coating metal consisting of different metals are defatted and cleaned, then the average surface roughness of the joint surfaces thereof is made 3-20mu and thereafter the metals are press-stuck to obtain a composite material. If the average surface roughness is >=3mu, the press sticking strength is high and if <=20mu, the rate of generating blister is decreased and the high press sticking strength is attained. The composite material having the high press-sticking strength is thus obtd. at a good yield by regulating the average surface roughness of the joint surfaces within the above-described range.

Title: Passing control method and device for transmission cell
Inventor: YAMAGUCHI TOMOYUKI

Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To attain improvement of line quality of a communication system by prohibiting all the cells that contain 1 bit errors and multi-bit errors in headers from passing through a cell processing device when a communication quality of a frame received is monitored and it is beyond a specified threshold value. SOLUTION: A transmission cell passing control device 20 consists of a frame monitoring means 21 and a cell buffer 22 and the cell buffer 22 is connected to a rear step of a cell extraction part 14 and temporarily stores a cell for one frame contained in each frame FR. The frame monitoring means 21 is connected to a frame synchronizing part 12 and monitors a communication quality of each frame FR. That is, a BER value monitored by a BER monitoring part 31 is compared with a threshold value held in a threshold value hold part 32 by a comparator 33. When the BER value exceeds the threshold value and is deteriorated, all the cells that contain bit errors are rejected by the cell buffer. On the other hand, when the BER value does not exceed the threshold value, the buffered cell is directly let pass.

The control means 15 the number of picture elements of the continued black levels with the number of picture elements stored in advance in a storage means 16. As a result of this comparison, in the case a ratio of the number of picture element of the black level is smaller than a ratio of the number of picture elements stored in advance, the control means 15 controls a warning sound generating means 12, and generates a warning sound.

Abstract: PURPOSE:To reduce outfit installation, the cost and to decrease the installation period by driving and controlling a shipboard antenna based on the result of direct measurement between plural shipboard antennas and a satellite. CONSTITUTION:The distance between 1st and 2nd shipboard antennas 10, 20 and a communication satellite A is measured from a bit difference obtained by a code bit difference measuring device 31 detecting a bit difference between a range finding code sent from transmitters 11, 21 and a range finding code received by receivers 12, 22. Then the elevating angle and the azimuth angle of the shipboard antennas 10, 20 are calculated based on the distance between the shipboard antennas 10, 20 and the communication satellite A and the elevating angle and the azimuth angle of the shipboard antennas 10, 20 are revised based on the calculated elevating angle and azimuth angle. Thus, it is not required to connect the shipboard antennas 10, 20 to a navigation aid and a driving controller for the shipboard antennas has only to be provided near the shipboard antennas. Thus, outfit installation is reduced, the cost is reduced and the installation period is decreased.
