Title: Hot gas engine
Inventor: HARADA TERUMARU
IPC: F02G1/053
Filed: 1980-06-26
Abstract: PURPOSE:To obtain constant pressure in both spaces of an engine and prevent loss of its power, by providing a partition plate in a low temperature space part and communicating the both spaces at piston and displacer sides of the partition plate with a control device having throttle valves and partition plate of diaphragm or the like. CONSTITUTION:Space 12 at the side of a piston 3 and low temperature space 6 at the side of a displacer 2 divided by a flexible partition plate 11 are communicated with a control device 15 having throttle valves 14 and a partition plate 13 of dia- phragm or the like. Then the control device 15 is provided with enough internal capacity capable of equally adjusting pressures in the both spaces. In this way, the pressures in the both spaces can be always kept constant, thus unnecessary force is never applied to the partition plate 11 capable of increasing a life of the partition plate 11. Further few amount of gas is circulated to the control device 15 during operation of the heat engine because of resistance of the throttle valve, thus obtained power can be taken out as the output almost without loss.

Title: Mist separator
Inventor: MAEDA YOSHITAKA
IPC: B01D39/20
Filed: 1978-07-20
Abstract: PURPOSE: To enhance the collection efficiency of a vertical type cylindrical mist separator with filter elements built-in by attaching an exhaust gas introduction pipe to the separator body in a tangential direction of a circle formed by the cross section of the body.  
     CONSTITUTION: Exhaust gas introduction pipe 1 is attached to the body of the mist separator in a tangential direction of a circle formed by the cross section of the body. Since large diameter mist and large diameter dust in exhaust gas fall to the separator bottom by the effect of centrifugal force before the gas reaches filter elements 3, the filtration load of elements 3 is relieved, the collection effect is increased, and the clogging due to adhered dust is prevented. The filtration chamber is partitioned with a porous plate or a net and consists of a layer formed by laminating thin glass fiber of about 5W15μ diameter and a layer formed by laminating thick glass fiber of about 20W30μ diameter. The thickness ratio of the layers is about 1:9W9:1, and exhaust gas is introduced from the thin glass fiber layer to the thick glass fiber layer.

A groove, which has the deep inclination and is perpendicular to the surface of the Well layer, is formed in the Well layer. Then, an oxidation mask is deposited on the entire surface in order to make Si3N4 2 remain at a part other than the bottom surface of the groove. Thereafter, etching is performed by anisotropic etching. For example, boron is implanted beneath SiO2 1 so as to perform electrical element separation, and a CSTOP region is formed. Then, heat treatment is performed in an O2 atmosphere, and SiO2 1 is formed. Thereafter, Si3N4 1 and Si3N4 2 on the surface are etched so as to form a gate. For example, Gox and G are deposited on the specified part of the surface.

Abstract: PURPOSE:To improve detection accuracy by a method wherein a bias voltage of a prescribed frequency is applied to an oxygen sensor to detect its internal resistance and the operation of a heater for heating the sensor is so controlled as to maintain the internal resistance constant. CONSTITUTION:A bias voltage VB is applied to an oxygen sensor 1 from a bias voltage application equipment 11 and a voltage level of the bias voltage VB is increased and decreased in accordance with an internal resistance value of the oxygen sensor 1. This voltage level is taken out by a band-pass filter 20 as a prescribed frequency component (signal voltage VA). An amplitude level of the signal voltage VA is detected by an amplitude detector 21 and smoothened to form a voltage signal VW. The operation of a heater 2 is controlled in accordance with this voltage signal VW. When the temperature of the oxygen sensor 1 is low (high), the internal resistance is increased (decreased) and the voltage signal VW shows a high (low) value. When the value of the voltage signal VW exceeds the predetermined value in a heater control circuit 43, the oxygen sensor 1 is heated by the heater 2 and when it is below the predetermined value, the heating is stopped.

Abstract: PROBLEM TO BE SOLVED: To improve durability while maintaining a wavelength resolution by supporting a mirror unit having a plurality of mirrors integrated by a leaf spring and displacing it. SOLUTION: A mirror unit 10 can be displaced in a lateral direction in a range of elastic deformations of leaf springs 13 and 14 since the unit 10 is fixed to a support material 15 by the springs 13, 14.
