Title: Fan motor
Inventor: WAKUI TOYOMITSU
IPC: H02P6/17
Filed: 1994-04-18
Abstract: PURPOSE:To reduce the electromagnetic noise from a motor by holding down the maximum value of conduction current of an inverter section which drives the fan motor and reducing other frequency components than a specified one. CONSTITUTION:Comparing a current command value 6a corresponding to a difference between a rotating speed command 5 and an actual rotating speed of a motor 3 with a triangular signal 11a from an oscillation circuit 11, a PWM signal generating circuit 12 generates a PWM signal 12a which has a duty ratio corresponding to the current command value 6a. The current command value 6a is so set that the maximum duty ratio of the PWM signal 12a may be 100% or smaller. When the conduction current I of an inverter section 2 reaches the current limit value IL, a current limiting circuit 10 generates current limiting signals 10a, 10b. A cycle of the PWM signal 12a is held down by the current limiting signal 10a in a composite circuit 7 and the duty ratio of the PWM signal 12a is made smaller by making the duration of the current limiting signal 10a and the current command value 6a smaller in a calculating and controlling circuit 6. The thus generated signal 7a is a driving signal of the inverter section 2.

Title: Processing of compound semiconductor material
Inventor: MATSUI TERUHITO
IPC: H01L27/15
Filed: 1989-03-29
Abstract: PURPOSE:To obtain an etching sidewall which is inclined uniformly by a method wherein a hydrocarbon-based gas in sued as a reaction gas for an etching operation and a material whose etching speed is close to that of a semiconductor material, is used as an etching mask. CONSTITUTION:When a reactive ion etching operation is executed by using a hydrocarbon-based gas, e.g. methane, and by utilizing a silicon dioxide(SiO2) film 2 as an etching mask, the etching speed of an InP substrate 1 as a compound semiconductor is proportional to a flow rate of methane as an etching gas and the etching rate of the SiO2 film 2 is not changed very much. Accordingly, as the etching operation progresses, a film thickness of the etching mask 2 is reduced and also an etching operation which progresses from an edge to a transverse direction is caused; an edge of the etching mask is retreated. As a result, a shape of a sidewall of the InP substrate 1' is not vertical after the etching operation and can be inclined with reference to a face of the substrate 1. Thereby, it is possible to obtain an etching characteristic of a side face which is inclined uniformly.

Title: Crosslinked polyolefin foam for pipe cover
Inventor: KENMOTSU TAKAAKI
IPC: F24F13/02
Filed: 1990-03-27
Abstract: PURPOSE:To obtain a foamed crosslinked polyolefin having excellent heat resistance and flexibility, by specifying rate of dimensional change on heating and Young's modulus. CONSTITUTION:A foamed crosslinked polyolefin for a pipe cover has a rate of dimensional change on heating according to JIS K 6767 (heating temperature: 110 deg.C) of 5% or below and a Young's modulus of 12-25kg/cm<2>. If the rate of dimensional change on heating is more than 5%, there arises the problem that, in use of the foamed polyolefin as a pipe cover for a piping through which a heat medium is circulated, the cover is welded to the surface of the piping when the piping surface temperature is raised to about 120 deg.C. That is, lowering in heat resistance is caused. A foamed crosslinked polyolefin with a Young's modulus of less than 12kg/cm<2> shows poor moldability in molding into a pipe cover, whereas a foamed crosslinked polyolefin with a Young's modulus of more than 25kg/cm<2> exhibits lowered flexibility. The foamed crosslinked polyolefin can be produced by blending various polyolefins with a crosslinking agent and a foaming agent in predetermined amounts to prepare a polyolefin resin composition, and subjecting the composition to crosslinking and foaming.

Abstract: PURPOSE:To decrease the operation time for a collision evasion by transmitting a task conforming to a change condition to a trajectory generation module, in the case when the task conforming to the change condition exists and operating a robot arm, and executing the task conforming to the change condition which can be executed safely instead of executing an operation for a collision evasion. CONSTITUTION:When danger of a collision is detected by a collision evasion module 4, a task management module checks first whether a task of a safe area which can be changed with the present task exists or not, and if such a task exists, it is changed with the present task and a robot arm is driven. When such a task does not exist, it is tried to generate a detour path for executing the present task, when the detour path cannot be generated, only a save path is generated simply. Subsequently, an evasion command of this detour or save path is sent to a trajectory generation module 2, converted to a pulse command and sent to a driver module 3, and the robot arm is driven. In such a way, the operation time for a collision evasion is decreased.
