Title: Phototransistor
Inventor: NAGATA KENICHI
IPC: H01L31/10
Filed: 1989-05-12
Abstract: PURPOSE:To manufacture a phototransistor having high withstand voltage besides a good in-phase signal removal characteristic and high hFE by making a p-type base region under an n-type emitter and a p-type base region of a light-receiving part shallow diffusion layers having low impurity concentration while forming deep diffusion layers having high impurity concentration in the respective peripheries. CONSTITUTION:A base part 3 directly under an emitter 5 is to be a shallow diffusion layer having low impurity concentration and a light-receiving part 4 also is to be a shallow diffusion layer having low impurity concentration, while high withstand voltage base parts 2, 2, 2, consisting of deep diffusion layers having high impurity concentration are formed so as to surround these. In this way, the base region 3 consisting of a p-type diffusion layer has low impurity concentration while being shallow so that diffusion time is shortened and variations in impurity concentration of diffusion and in the diffusion depth are reduced even in the case of high hFE. Further, the p-type base region 4 also of the light-receiving part has low impurity concentration while being the shallow diffusion layer so as to get high- resistance. Accordingly, getting hard malfunctioning, an in-phase signal removal characteristic is improved. Further, withstand voltages between the base and the emitter as well as between the collector and the emitter can be improved by forming a deep diffusion layer 2 having high impurity concentration.

Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To provide a composite optical element capable of obtaining a characteristic for the reduction of stray beam also in the structure to detect the front surface emission beam of laser diode for automatic laser beam output control. SOLUTION: The beam emitted from a laser diode 12 strikes against the prism surface 16a with an angle of 45 deg. of a prism 16, is reflected perpendicularly, and then is separated into a beam proceeding to a disk and into a beam passing through the interior of prism. This beam further passes through a reflection protective film 17 formed on the rear surface of prism 16, is detected by an optical detector 15, and then is applied to automatic output control to keep the emitted power of laser diode 12 at a constant level. Among the beams transmitted to the interior of prism 16, the stray beam generated through reflection, scattering and the like are absorbed by a absorption film 18 formed on the rear surface of prism 16. Thereby, it is attainable to detect the beam signal for automatic control and to reduce the stray beam at the same time.

Inventor: KIDA OTOJIRO
IPC: C04B35/057
Filed: 1987-05-19
Abstract: PURPOSE:To obtain a slaking-resistant CaO refractory having bonded parts characterized by CaB6 containing no free CaO. CONSTITUTION:A calcareous refractory having bonded parts characteristized by CaB6 containing no free CaO, formed on CaO-containing Clinker having controlled particle size. In calcareous Clinker as a refractory, an indeterminate- form refractory such as blown material adjusted to 5-1mm coarse particles and 1-0.1mm middle particles is generally adjusted to <=1mm. To prevent slaking resistance, preferably regular-shape refractory is adjusted to 5-1mm coarse particles and 1-0.3mm middle particles and a refractory such as blown materials is adjusted to 1-0.3mm particle size. The adjustment is carried out because there is time limitation of use of an actual furnace wherein the refractory is slaked and collapsed for a week at 20 deg.C and at >=95% RH when the particle size is >=0.3mm. At least >=50wt.% CaO Clinker adjusted to 0.3-5mm particle size in a refractory raw material is preferably used from this point of view.

Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To realize constant power consumption and constant waiting time regardless of the fluctuation of a power source voltage due to an area or the fluctuation of the power source voltage due to a time band by measuring the voltage and the current of an AC line inputted to a device, controlling the power which can be supplied to the maximum and supplying constant power. SOLUTION: By measuring the voltage and the current of the AC line inputted to the device, the power which can be supplied to the maximum is controlled. These are executed by a current detection means 107, a voltage detection means 108 and a fixing controller 109. By the detection means 108, a pulsating voltage synchronized with a voltage generated at the voltage of the AC line is generated by a rectification device 110 whose capacity is small. Then, when the pulsating voltage becomes 0 V and 74 V, the light emission of the corresponding photocouplers 111 and 112 is stopped and a signal is transmitted to the controller 109. By the controller 109, the time taken from 0 V until an AC voltage becomes 74 V and the time taken until it becomes 0 V next are measured. Then, it is decided what Hz of frequency the AC voltage is.

Abstract: PURPOSE:To remove a sheet of recording paper easily when a feeding trouble such as meandering is generated, by conveying sheets of recording paper between a paper feed roller and a press roller provided with a magnet in at least one of them to attract each other. CONSTITUTION:A paper feed roller 7 is constructed with a magnetic tube 20 made of iron material covered with an elastic rubber layer on the periphery, and a 1st and a 2nd press roller 8,9 are provided with a permanent magnet 32 on the periphery of a shaft 31, and guided with a guide portion 33 to contact to the roller 7 by an attractive force. Thereby the pressing force of the roller 8 is reduced as the roller is separated from the roller 7. When a sheet of recording paper 6 is stopped in the feeding channel between the roller 7 and the rollers 8,9, the pressing force to the paper 6 can be reduced by separating the press roller 8 from the roller 7. Thereby such troubles that the recording paper 6 is pinched firmly or hardly removed can be prevented.
