Title: Moving coil type coil bobbin and manufacture thereof
Inventor: TANAKA AKIHIRO
IPC: H04R9/04
Filed: 1994-10-17
Abstract: PURPOSE: To facilitate transmission of a driving torque to a diaphragm and to manufacture a bobbin without any secular change in its acoustic characteristic by using polyethersulfone as a material of the coil bobbin so as to reduce the weight of the coil bobbin, providing a high elasticity and a high heat resistance. CONSTITUTION: The bobbin is used for a moving coil and a tube shaped film without any end is obtained by heat-extruding a plyethersulfone from a torus dice. A moving coil 1 used for a speaker, a microphone and a receiver of a telephone set or the like is used by cutting off the tube endless film used for the voice coil bobbin 2 to be a prescribed length. A magnet wire 3 from one end is wound on the outer diameter of the tube shaped film and both ends 3a, 3b of the wire 3 are extracted. In this case, paper is inserted under the magnet wire 3 as required, that is, onto the outer circumferential face of the bobbin 2. Thus, the bobbin without a secular change in the sound characteristic is obtained.

IPC: D06H3/00
Filed: 1988-11-17
Abstract: PURPOSE:To output a stable signal against a variation of an ambient temperature and a wavy fluctuation of an object to be measured by decreasing an interference of an ultrasonic transmitter, and a reflected wave from an ultrasonic receiver and the object to be measured. CONSTITUTION:An ultrasonic transmitter 1 and an ultrasonic receiver 2 are placed so as to be opposed to each other, and between them, an object to be measured is installed in a state separated from both the transmitter 1 and the receiver 2. As for the object to be measured, there are the time when it exists entirely on the transmitting surface of the transmitter 1, the time when it exists partially, and the time when it does not exist entirely. Also, the transmitting surface of the transmitter 1 and the receiving surface of the receiver 2 are inclined at a prescribed angle, and since a reflected wave from the receiving surface does not return to the transmitting surface, the reflected wave and a direct wave from the transmitter 1 do not interfere with each other, and a stationary wave is scarcely generated. Therefore, the instability of an output signal of the receiver 2 caused by the stationary wave is eliminated, and a stable output signal can be obtained.

Title: Control device of turbocharger with rotary electric machine
Inventor: ASAZAWA YASUAKI
IPC: F02B37/10
Filed: 1990-10-29
Abstract: PURPOSE:To prevent electric driving which is not necessary for a rotary electric machine by detecting fluctuation of supercharging pressure in relation to fluctuation of the rotational speed of a turbocharger so as to detect the variable level of the atmospheric pressure and correcting supercharging pressure on the basis of the detected signal. CONSTITUTION:In a controller 6, a boost pressure in the idling condition of an engine 1 is measured by a boost sensor 1h based on a signal from an acceleration sensor 1c, and a pressure difference between this measure value and normal boost pressure is used as a correction reference value. The changing amount of the boost pressure is found out from a correlation coefficient and the turbine rotational speed changing amount from a certain point of time during operation until a prescribed time passes, and expected boost pressure after a prescribed time is calculated. And then, a boost pressure correction value is calculated by increasing/decreasing a differential pressure between an actural boost pressure and expected boost pressure from the correction reference value, and the boost pressure measured on the basis thereof is corrected. It is thus possible to avoid electrification of a rotary electric machine 3 which is not necessary at the time of operation at highland where air pressure is low, and control with high efficiency can be carried out.

Abstract: PURPOSE:To effectively cool a substrate and to prevent the deformation and failure thereof by a high temp. by forming a substrate holder of a shape memory alloy at the time of forming a thin film by a sputtering method, etc., on the substrate surface. CONSTITUTION:The surface of the substrate 3 is held at an adequate temp., by which the damage of the substrate 3 by the high temp. is prevented at the time of forming the thin film on the surface of the substrate 3 by a method, such as sputtering. In addition, the temp. of the substrate 3 is optimized, by which the form and crystallinity of the thin film formed on the surface are improved. The cylindrical substrate 3 is inserted onto the cylindrical substrate holder 1 made of the shape memory alloy internally provided with a circulating path 2 for cooling water so as to form a spacing between both. The temp. of the substrate 3 is increased by the reaction to form the thin film by the sputtering. The substrate holder 1 made of the shape memory alloy comes into tight contact with the substrate 3 when the temp. of the substrate 3 rises and attains the preset transformation temp. of the shape memory alloy or above. The substrate 3 is then cooled by the cooling water via the substrate holder 1. The deformation and thermal crack of the substrate 3 by the high temp. are thereby prevented.
