Title: Cutting method and cutting device of brittle material
Inventor: TAKAGI TETSUJI
IPC: B26D1/02
Filed: 1988-02-19
Abstract: PURPOSE:To prevent breaking to a cutting edge generated at a final cutting point of a brittle material and substantially increase the critical number of cutting by providing a pedestal equipped with springs capable of freely adjusting their angle and elastically supporting the lower face of a portion to be cut close to the final cutting point of the brittle material. CONSTITUTION:A brittle material 50 is held with its portion 51 to be cut projected sideways on a support trestle 1 and passed through below a cutting edge 1, along with a moving carriage 4, and the brittle material 50 is cut from left to right and a final cutting point is cut off finally. In this instance, springs 5 of a pedestal 6 push up the lower face of the portion 51 to be cut to produce an upward force against the dead load of the brittle material 50 and a cutting force. Accordingly, no relative force is generated between the portion 51 to be cut and the brittle material 50 body. As a result, when the number of cutting of the cutting edge 1 is over five tens of thousands and the resistance to cutting is increased, no breaking to the cutting edge is generated, and thus the critical number of cutting of the cutting edge can be substantially increased.

Title: Film forming device
Inventor: TOKUDA NORIFUMI
IPC: H01L21/31
Filed: 1990-02-20
Abstract: PURPOSE:To decrease the area of the inner wall face of an inner tube thereby reducing the quantity of the film grown on the inner wall face of the inner tube to prevent the adhesion of foreign matter to a board by providing the wall face of the inner tube with many holes. CONSTITUTION:In an inner tube 11, which consists of quartz tube and is provided inside an outer tube 2, many round holes 11a are provided at the whole wall face. And the inside of the inner tube 11 becomes the reaction chamber for growing a film, and a reaction product grows as a film on the wafer being a substrate within this reaction chamber. But in this case, since many ports 11a are provided at the wall face of the inner tube 11, the area of the inwall of the inner tube 11 is much smaller than the conventional case. For this reason, the quantity of reaction products filming on the inner wall face of the inner tube by the long-term use also becomes small. Hereby, the quantity of foreign matter by the separation of the reaction products on the inner wall face of this inner tube 11 becomes small.

Abstract: PURPOSE:To obtain a small-sized, low-price two-dimensional actuator which has simple constitution and consists of a small number of parts by fitting an annular yoke which has a cylindrical projection part between the inner cylinder and outer cylinder of a lens holder on one side of an annular magnet, and arranging springs between the yokes and lens holder. CONSTITUTION:When a current is flowed through a focusing coil 8 arranged at a gap part 10 while the annular magnet 9 produces magnetic flux at the gap part 10 through yokes 11 and 15 as shown by an arrow, the force in the optical-axis direction of a condenser lens 4 is generated at the lens holder 1 and the spring 16 while holding the lens holder 1 rolls in a focusing direction to drive the condenser lens 4 in the focusing direction. Further, when a current is flowed through a tracking coil 7 while the annular magnet 9 produces magnetic flux at the gap part 10 through the yokes 11 and 15 as shown by the arrow, the force of the vector sum of restoring forces of both springs 16 drives the lens holder at right angles to the optical axis while holding it, and the lens holder 1 is thus driven to drive the condenser lens 4 in the tracking direction.

Filed: 1982-03-10
Abstract: PURPOSE:To prevent the flow of steam from reaching a rotor shaft and eroding it, by providing communication passages in the inner ring, plate and outer ring of a nozzle section so that the steam which would flow along the inside of the inner ring of the nozzle section is conducted to the vicinity of the outlet port of a casing through the communication passages. CONSTITUTION:The inner ring 8 of a nozzle section is provided with circumferential grooves 12 located near the inside of the ring and concentric to each other and is provided with Y-shaped passages 13, the number of which is equal to that of nozzle plates 9 and each of which has two branch parts opened in the bottoms of the circumferential grooves 12 and connected to each other in the nozzle plates 9 outside the inner ring 8 of the nozzle section. Each nozzle plate 9 is provided with a passage 14 connecting to the passage 13 and extending in the diametral direction of a nozzle diaphragm 10. The outer ring 6 of the nozzle section is provided with drain passages 15 connected to the passages 14 and opened near the outlet ports 11 of a casing 1. Since the pressure at the outlet opening of the drain passage 15 is lower than that at the circumferential grooves 12, the steam entering into the spaces between the inner ring 8 of the nozzle section and rotor discs 3 is drained through the passages 13-15.

Title: Digital microwave communication equipment
Inventor: SATO KAZUMASA
IPC: H04J1/00
Filed: 1988-02-22
Abstract: PURPOSE:To obtain a digital microwave transmitting device to decrease an inter-adjoining-channel interference without lowering frequency using efficiency by providing a filter to cut the band edge of a modulation spectrum at a transmitting side. CONSTITUTION:A band filter 1 is filter to band-limit a modulated wave signal (a).

Consequently, a transmitting capacity can be increased, and also frequency using efficiency is improved.

Abstract: PURPOSE: To improve the efficiency of heat collection by using a mixed system, which consists of a component being composed of an air component, the gaseous phase, and a water-steam system under gas-liquid equilibrium and the rate of gaseous phase volume thereof is 50vol% or more, as a heat collecting medium in a solar heat collecting system.

A transmitting property of heat lies between air and low-pressure steam regarding heat receiving, and obtains performance close to the low-pressure steam regarding heat receiving, and obtains performance close  to the low-pressure steam regarding radiation. A phasic change due to the transfer  of heat is approximately constant working pressure because the partial pressure of  air and the partial pressure of steam change and correspond. If the medium is applied to a system utilizing solar heat of 2m 2  effective heat receiving area, the flow  rate of the air/water-steam system medium is 87kg/H when water alone to 21.2kg/H  and 350kg/H when air alone when the same quantity of heat collected of 957Kcal/ H is obtained under the conditions of 50°C inlet temperature and 61°C outlet temperature.

Title: Thermal deterioration detecting method
Inventor: OSHIYAMA TSUTOMU
IPC: G01N25/00
Filed: 1983-03-08
Abstract: PURPOSE:To detect a degree of thermal deterioration by deriving in advance a degree of deterioration of an insulating organization as a function of temperature and time, from a variation of a dynamic visco-elasticity characteristic of an insulating material, and comparing it with a sample from an actual operating electric apparatus, which is extracted from an advancing process of a continuous deterioration. CONSTITUTION:For instance, in case when a variation of a chemical structure quantity (x) due to a thermal deterioration follows a chemical reaction speed theory, when a deterioration time, a frequency factor, a deterioration activated energy, a gas constant, an absolute temperature of deterioration, and a function for showing a reaction mechanism are denoted as (t), A, DELTAE, R, T and g(x), respectively, and the deterioration advances from time ''0'' to (t), and the chemical structure quantity is varied from x0 to (x), an expression is formed. In a deterioration area in which the function g(x) and the frequency factor A are constant, even if the deterioration is generated under various temperature conditions, if a conversion time theta is equal, a variation of the chemical structure quantity (x) also becomes equal. For instance, when a dynamic visco-elasticity characteristic P is determined clearly by the chemical structure quantity, a degree of thermal deterioration theta is derived from a variation of the dynamic visco-elasticity characteristic P.
