Patent JP-S5788760-A (JP)
Title: Semiconductor device
Inventor: NOHARA JIYUNICHI
IPC: H01L29/73
Filed: 1980-11-25
Abstract: PURPOSE:To improve the breaking strength of a parasitic diode by a method wherein the section of the base-emitter short-circuiting hole of an output-stage transistor connected by a Darlington method is made into a shape causing little concentration of electric fields. CONSTITUTION:Transistors Q1 and Q2 are formed on an Si substrate 1 by a Darlington connection, and a stabilization resistor RBE is provided between the base 2 and the emitter 3 of the output-stage transistor Q2. This resistor RBE is formed of the short-circuiting hole 4 which has a depth from the surface to the base in a part of the emitter and is the same conductive layer with the base. As the result, a parasitic Zener diode DZ is incorporated in between a collector and the emitter. When high negative surge flows in DZ, electric fields concentrate in the corner of the section thereof and thereby DZ is destructed within allowable current. When the section of DZ is shaped into a circle or a polygon having an obtuse interior angle, the concentration of the electric fields is reduced and thereby the breaking strength against the negative surge is improved.

Abstract: PURPOSE:To prevent an electric leak through a magnetic carrier by interposing a means which relays and conveys the magnetic carrier to make independent electrically a sleeve for a magnetic brush and a toner recovery roll. CONSTITUTION:The relay sleeves 2 and 3 are interposed between the magnetic brush 1 and the toner recovery roll 4 to relay and convey the magnetic carrier, and the brush 1 and the roll 4 are made electrically separate and independent. Consequently, it is not necessary to impress a high voltage for toner recovery to the roll 4 as is the case when no relaying and conveying means is provided, and the electric leak through the carrier is prevented to perform a smooth cleaning. Further, insulation, etc., are facilitated and the circulation path of the carrier is extended to increase the amount of the carrier, reducing its fatigue.

Title: Semiconductor manufacturing equipment
Inventor: SATO RYUICHI
IPC: G03F7/22
Filed: 1985-07-25
Abstract: PURPOSE:To prevent an erroneous operation by grouping many commands and operation parameters when operating a semiconductor device according to the commands and the parameters, naming the groups, storing the names, and displaying them when the command is queued. CONSTITUTION:When a queue command from a command input processing portion is input in step S21, whether it is a command of execution level or not is judged in step S22. If it is the execution level, it is processed correspondingly. If not, the name of the group is judged in step S23 to display an error in step S24, and returned to the step S21. If the name of the group judged in the step S23 is to be executed, this data is displayed on a CRT in step S25, and transferred to an execution in next step S26. At this time, if the data are grouped according to the function of the execution command and the name, it is very effective to retrieve an unclear command and to prevent the erroneous operation in case of inputting a parameter.

CONSTITUTION:An input 1 is calculated from a desired response O by using a transfer function H1 found from a known input and a response and instructed as target input position data to a numerically controlled incompletely round work machining device. At this time, a transfer function H2 is calculated by using a response Oi in a frequency range by the equation unless the obtained response 1 has an error converged within a desired permissible value. A new input 2 is calculated as the target input position data from the desired response by using this transfer function H2. This operation is repeated until the error is converged and repeated while the transfer function is corrected until a specific control result is obtained to enable the numerically controlled incompletely round work machining with high precision. In the equation H(jw) is the frequency transfer function, I(jw) is the target input position data (frequency range), and O(jw) is actual movement data (frequency range) on a machining tool.
