Filed: 1995-03-27
Abstract: PURPOSE: To simply carry out the automatic control over the steaming degree at a low cost and enable the rationalization of a green tea manufacturing process and an improvement in quality of a product by measuring the power of a stirring shaft-rotating type green tea manufacturing steamer and controlling the steamer so as to keep the steaming degree constant based on the measured power. CONSTITUTION: The power of a stirring shaft-rotating type green tea manufacturing steamer is measured to control the steamer based on the measured power so as to keep the steaming degree constant. Specifically, when, e.g. the rotational frequency [(n) r.p.m.] of the rotating shaft and the flow rate S(kg/hr) of raw green tea leaves per unit time are constant, the steaming time [(t) hr] is proportional to the power E(kW) according to formula t=W/S=(E/ K1 ).(1/S) [(t) is the steaming time (hr); W is the amount (kg) of the green tea leaves present in a drum; E is the power (kW) of the steamer; (k1 ) is a constant]. Thereby, the power is measured to regulate the steaming time by the tilt of the drum when the measured value is out of the set value in order to keep the steaming degree constant. Furthermore, the torque is regarded sa indicating the steaming degree from formula T=(D/2)×(W+N) [T is the torque (kg/cm); N is the frictional force (kg) between the drum and the stirring shaft; D is the diameter (cm) of rotating drum]. Thereby, the rotational frequency is preferably changed according to formula E=0.735×(2πTn/71620) in order to keep the steaming degree constant when the power varies.

Title: Method and device for simulating characteristic with time of exhaust gas catalyst
Inventor: EERITSUHI SHIYUNAIDAA
IPC: G01M15/04
Filed: 1992-04-14
Abstract: PURPOSE: To ensure a reliable model and obtain an appropriate scale for indicating catalyzer deterioration by simulating the time-dependent performance of the catalyzer based on the relationship between the overflow and insufficient thresholds and the like relative to the oxygen storage of the catalyzer. CONSTITUTION: Time dependent performance of the lambda value λ-H-SIM at the outlet of an exhaust gas catalyzer of a motor vehicle having an internal combustion engine is simulated.

Title: Manufacture of field-effect transistor
Inventor: OKAMURA MASAMICHI
IPC: H01L29/78
Filed: 1988-04-15
Abstract: PURPOSE:To prevent P voids from generating in a channel region at the time of heat treatment by a method wherein, after an ion implantation is performed in source and drain regions, a group V element is ionimplanted in the channel region and its vicinity and, thereafter, a heat treatment is performed. CONSTITUTION:When an impurity of Si or the like is ion-implanted in a P-type or semi-insulative InP substrate 1, P is implanted simultaneously to form first a B region 12 having excessive P. When this region is activated by heat treatment, the P is diffused under the B region 12, in which Si or the like is implanted, in the InP substrate 1 and a C region 13 is formed because the self- diffusion coefficient of the P in the InP substrate is larger than the diffusion coefficient of other impurity of the Si or the like. After this, a FET is completed by a normal heat treatment. According to such a way, even if P voids are generated in a channel region 11 by a heating treatment in the manufacturing process of the FET, these can be filled with the excessive P which is implanted in advance. Thereby, the generation of the P voids can be decreased. As a result, a reduction in electron mobiity can be prevented.

Title: Differential variable amplifier circuit
Inventor: MATSUDA MASAO
IPC: H03G3/12
Filed: 1984-05-10
Abstract: PURPOSE:To obtain a differential variable amplifier circuit with which the effect of the ON resistance of an analog switch can be neglected, by providing the 2nd analog switch means which works in response to the 1st analog switch to a differential amplifier circuit which uses an analog switch for changeover of a gain setting resistance. CONSTITUTION:The effect of the ON resistance of an analog switch can be virtually neglected since the input impedance of an operational amplifier is very high. The amplification degree A is equal to (R2+R3+R4+R5)/R1 in case only a pair of SW1 is kept ON. While A=(R3+R4+R5)/(R1+R2) is satisfied when only a pair of SW2 is kept ON. In such a case, the gain of a differential variable amplifier circuit can be set regardless of the ON resistance of the analog switch.

IPC: H01S5/00
Filed: 1991-03-29
Abstract: PURPOSE:To improve the etching controllability of a flattened layer in the manufacturing method of a semiconductor laser having a light emitting area surrounded by groove areas. CONSTITUTION:By detecting the light emission 13 from an organic substance 12 constituting a photoresist 10 used as a flattened layer when the photoresist 10 is dry-etched, the hourly variation of the intensity of the light emission 13 is observed. While the intensity of the light emission 13 is strong in the initial stage of the etching, since the photoresist 10 adheres to the entire surface of a substrate, the intensity extremely decreases as the grown surface is exposed, since the photoresist 10 is left in groove areas 7 only. Therefore, the ending point of the etching can be detected from a noticeable change in the intensity of the light emission 13.
