Title: Impurity analyzing method of silicon substrate and its vapor phase cracking device
Inventor: MOHAMMAD B SHABANY
IPC: G01N33/00
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To provide a vapor phase cracking device with a simple structure, which can precisely analyze impurities of a silicon substrate in a relatively short time by cracking vapor phase without application of heat or pressure, and in which a reaction container does not require high sealability, a large wall thickness, and a concave upper internal. SOLUTION: A silicon substrate 15 and a decomposition liquid 11 are respectively accommodated within an airtight reaction container 10 such that the decomposition liquid 11 is not contacted with the silicon substrate 15. The silicon substrate 15 is put on a support 14, while the decomposition liquid 11 is formed by mixing hydrofluoric acid, nitric acid, and sulfuric acid. The decomposition liquid 11 vaporizes without application of heat or pressure to the reaction container 10 so as to decompose and sublimate the silicon substrate 15. Decomposition residua 18 of the silicon substrate 15 are collected so that impurities of the silicon substrate 15 are analyzed.  The sulfuric acid of the decomposition liquid 11 absorbs water of the hydrofluoric acid and the nitric acid of the decomposition liquid 11, and also absorbs water in air within the airtight reaction container 10 so as to lower a humidity in the airtight space. Thereby, the vaporization of the decomposition liquid 11 is promoted without application of heat to the decomposition liquid 11 or without particular application of pressure to the reaction container 10.

Abstract: PURPOSE:To allow the formation of a gray scale pattern over a wide range on the surface of a photosensitive body by previously regulating the quantity of irradiation light and the amplification factor of a detection signal such that the light reflected on the surface of the photosensitive body will have a constant level. CONSTITUTION:Prior to formation of a plurality of stages of gray scale pattern on the surface of a cylindrical photosensitive body, an optical sensor 22 for optically detecting each gray level of gray scale pattern detects the state of light, projected from a LED lamp 21 and reflected on the surface of the photosensitive body, a plurality of times. In this regard, a detection signal is outputted each time and a switching control unit 28 regulates the quantity of light from the lamp 21 and/or the amplification factor of the optical sensor 22 such that the detection signal has a constant level (average value). The average output value is read out as a reference value of low gray level and a gray scale pattern is formed on the outer peripheral surface of the photosensitive body.

Title: Method for controlling flow rate of injection cylinder
Inventor: MIHARA TAKASHI
IPC: B29C45/77
Filed: 1983-11-01
Abstract: PURPOSE:To make the increasing time of casting force uniform and to control flow rate to a prescribed time irrespectively of the injection speed just prior to completion of filling a molten material into a cavity by providing separately an opening degree for filling and pressurizing to a flow rate control valve and controlling the flow rate. CONSTITUTION:A magnetic detector 27 detects the scale of a magnetic scale 21 and forms the same as an impulsive signal. A stroke detector 28 counts the signal and provides the stroke position St of a plunger 4. A speed detector 29 converts the stroke position St to the speed signal (v) of the plunger 4 and an acceleration detector 30 converts the speed signal to an acceleration signal alpha. A judger 31 receives the signal alpha when the signal (v) attains a specified speed threshold v0 and judges whether said signal attains a negative value or not. A stroke setter 25 outputs a coincidence signal when the stroke signal from the detector 28 coincides with the set stroke position. An opening degree controller 24 regulates a flow rate control valve 33 by means of a pulse motor 32 until the valve opening degree set in an opening degree setter 26 upon receiving of said signal.

IPC: H05B33/22
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To provide an electroluminescent element with no uneven luminance and its manufacturing method. SOLUTION: An organic EL(electroluminescent) panel 1 is formed by stacking an anode 11, a low resistant metal electrode 12, an organic EL layer 13, and a cathode 14 on a transparent glass substrate 10. The anode 11 is constituted with ITO (indium tin oxide) and has high sheet resistance. The low resistant metal electrode 12 is formed on the circumferential end of the anode 11. The low resistant metal electrode 12 has low sheet resistance. The organic EL layer 13 is made thinner with increase in distance from the low resistant metal electrode 12. Voltage applied from an anode extraction terminal 11a is almost not dropped in the low resistant metal electrode 12, but produces voltage drop in the anode 11.  Since the organic EL layer 13 is made thin in the central part where voltage between the anode and the cathode is low, light having almost the same brightness is emitted in the whole organic EL panel 1.

Title: Method of controlling paper feed in image recorder
Inventor: INOUE MOTOICHIROU
IPC: B65H7/20
Filed: 1981-12-17
Abstract: PURPOSE:To improve the control of the distance between sheets of paper and heighten the speed of recording, by measuring time from the sending of the sheet found out by a paper detector provided at a paper feed means, to start a paper feed roller after the lapse of prescribed time. CONSTITUTION:When the front end of paper is detected by a sensor 8, a timer starts measuring time. Otherwise, some modification is effected on the timer measuring time from the preceding feed of paper, when the sensor 8 has detected the front end of the paper. In that case, at the lapse of time T set on the timer, a paper feed roller 3 is rotated to perform the succeeding feed of paper. A driving mechanism for the paper feed roller 3 is connected thereto through a one-way clutch so that accompanying rotation is caused after the paper has started being conveyed by overlap feed prevention rollers 4. The time T set on the timer is predetermined at an appropriate value larger than the time that it  costs the paper to be conveyed by a distance equal to the sum of the length of  the paper and a range (t) of irregularity.
