Title: Preventing device for temperature-rise in rotary valve
Inventor: SATOU KANJI
IPC: B23Q11/12
Filed: 1980-03-25
Abstract: PURPOSE:To prevent the temperature-rise of the rotary valve by a method wherein a heat pipe is fixed near the rotary valve at the rear end of a main spindle and the outwardly exposed fin of the heat pipe is cooled with air or coolant. CONSTITUTION:A chuck body 5 is installed at the front end of the main spindle 1 and a cylinder 8, having an adaptor 7 as an interposition, is fixed as one body with the main spindle at its rear end. The main spindle 1 is revolved to work a work W with the movement of the tool. The cylinder 8 is also revolved with the revolution of the main spindle 1 and the leaked oil from grooves 13A and 13B connected with the cylinder 8 is stirred at the position of learings 10 and 11 to raise its temperature. As the fin part 19A of the heat pipe 19 is exposed rearwards, the heat is carried to this fin part 19A to which air is sent in the direction as indicated by an arrow head by a fan 20 installed at the rear end of the main spindle 1 to lower the temperature of the spindle head.

Title: Cassette box for magnetic recording and reproducing device
Inventor: TAKITA KOHEI
IPC: G11B33/02
Filed: 1987-02-23
Abstract: PURPOSE:To prevent the mixture of foreign matters into the main body of a magnetic recording and reproducing device by using a 1st upper cover fixed to a cassette box and a 2nd upper cover which is energized to prevent the exposure of said main body in response to the shift of a cassette box to constitute an outer shell which covers the upper part of the cassette box. CONSTITUTION:A 2nd upper cover 3 can slide in the same direction as the sliding direction of a cassette box 5 against a 1st upper cover 2 fixed to the box 5 and at the same time is always energized in its sliding direction. Therefore the box 5, even if slided and separated from a cylinder 15, stays at that position since a part of an outer shell 1 for the magnetic recording and reproducing device main body functions as a stopper. Thus the box 5 fills the gap formed between the cover 2 and the shell 1 by the sliding action of the box 5 so that the exposure is avoided for the inside of said device main body. As a result, the mixture of dust is prevented to the inside of the recording and reproducing device and a head is surely protected.

Title: Gas measuring apparatus
Inventor: OKUBO KUNIHIKO
IPC: G01N29/02
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To obtain a gas measuring apparatus by which a plurality of components concentrated by heating and desorption are separated so as to be detected. SOLUTION: When sample components adsorbed to an adsorbent in a collecting tube are desorbed, the temperature of the sample components is first raised steeply up to a temperature T1 which is higher than the boiling point of a low-boiling-point component and which is lower than the boiling point of a high-boiling-point component, and it is maintained at the temperature T1. Thereby, the low-boiling-point component is desorbed quickly from the adsorbent so as to be introduced into a sensor at a high concentration. Then, the temperature of the sample components is raised steeply up to a temperature T2 from the temperature T1, and it is maintained at the temperature T2. Thereby, the high-boiling-point component is desorbed quickly from the adsorbent so as to be introduced into a sensor at a high concentration.  In this manner, the sample components whose boiling point, i.e., melecular weight, differes largely are separated in terms of time so as to be introduced into the sensor. When detection signals of the sensor are separated and processed, the discriminating property or the like of the odor of a sample gas can be enhanced.

IPC: H05B6/76
Filed: 1988-02-22
Abstract: PURPOSE:To allow to restrain generation of heat or sparks by lessening leaking electric power by means of the action of collar-like circular conductor plate. CONSTITUTION:An circular inhibiting plate 9 is made of metal and faces a heating chamber bottom surface 1 with a fixed space. The path of microwave which is going to leak comes in from space between the circular plate 9 and the heating chamber bottom surface 1 and permeates through an upper portion bearing 4 so as to pass through a through hole 2, then it is going to be propagated on the coaxial line on the inside of a pipe 11. But the pipe 11 is a choke, and thereby it can not be propagated on this coaxial line and is reflected on a choke inlet 2a so as to be returned to a heating chamber passing the reverse path. The electric power of the microwave which is going to leak can be particularly lessened by means of the circular inhibiting plate 9. With this arrangement, heat generation and sparks due to food scraps adhered can be restrained.
