Title: Mechanical deflector for high speed rotary polygonal mirror
Inventor: KAWABE TAKANARI
IPC: G02B26/12
Filed: 1987-04-27
Abstract: PURPOSE:To double the number of times of scanning on a scan film per second by arranging a polygonal mirror and an optical system between a rotary polygonal mirror and a screen and projecting the light reflected from the rotary polygonal mirror on the screen through the polygonal mirror and the optical system. CONSTITUTION:A laser light L2 which is made incident on and is reflected from a rotary polygonal mirror M1 first scans the surface R1, one of the multisurface reflection mirrors in accordance with the rotation of the rotary polygonal mirror. The laser light reflected from this surface R1 is reflected from the surface K1, one of the multi-surface adjusting mirrors to scan a screen S from a point A to a point B. As the rotary polygonal mirror is farther rotated, the laser light is made incident on a surface R2 of the multi-surface reflection mirrors and passes the reflection surface K2 of the adjusting multi-surface mirrors and the optical system to scan the screen S from the point A to the point B. The laser light incident on the rotary polygonal mirror M1 scans the screen S (m) times if the number of surfaces of the newly introduced multi-surface reflection mirrors is denoted as (m). Therefore, the laser light scans the screen S nXm times during one rotation of the rotary polygonal mirror. Thus, the number of times of scanning of the laser light per second is nXmXf where (f) is the number of times of rotation of the rotary polygonal mirror per second, and this number of times of scanning is (m) times as large as that of the conventional method.

Abstract: PURPOSE: To arrange so that a correct outdoor temperatures can be estimated without being affected by a direct solar beam, rain, dew, etc. by estimating the outdoor temperature with detected value obtained by a room temperature sensor and a refrigerant pressure sensor.  
     CONSTITUTION: A refrigerant temperature T e  at the position of a refrigerant pressure sensor 10 is a function of the room and outdoor temperatures T g , T o , so that a functional relationship between refrigerant temperature T e  and refrigerant pressure P is established, although it is not applied otherwise. This relationship formula is memorized by an outdoor temperature estimation device 12. In the meantime, a room temperature TR is detected by a room temperature sensor 9 and refrigerant pressure P by the refrigerant pressure sensor 10. These detected values TR, P are inputted to the estimation device 12 and then the outdoor temperature T o  is arithmetically operated on the relationship formulae 1, 2. Thereby, it is possible to transmit a signal corresponding to the outdoor temperature T o  as an output from the estimation device 12.

IPC: F02C7/143
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To perform efficient cooling of intake air. SOLUTION: In a heat-exchanger to cool intake air, intake air is cooled by an intake air cooling subsystem and a cooling subsystem using the heat of vaporization of LNG and the latter is used for cooling of a part where temperature is low. Further, purified mist (fog) is mixed in intake air of a gas turbine and a substantial cooling efficiency is increased. In the intake air cooling subsystem, when ammonia is used as a refrigerant and water is used as an absorbing, high concentration ammonia steam vaporized by absorbing the heat of intake air is absorbed in a low concentration ammonia solution remained after vaporization of ammonia, and the absorbing heat is used in vaporization of the refrigerant.  Further, in this case, in a heat-exchanger to cool the intake air, vaporization of the refrigerant is effected by a pressure in a plurality of stages and an amount (a ratio) of the refrigerant used in vaporization cooling is increased (ensured).

Title: Method and device for forming plasma armature of rail gun type electromagnetic accelerator
Inventor: USUHA SHIYUU
IPC: F41B6/00
Filed: 1990-04-18
Abstract: PURPOSE:To form a plasma armature easily with good reproducibility by a method wherein line explosion plasma is blown into an accelerating hole through a fine hole and arc discharge is generated to form the plasma armature by a plasma forming material at a specified place. CONSTITUTION:A total current is conducted at first through a line explosion circuit simultaneously with the starting of electric discharge while plasma, generated by line explosion, is blown into an accelerating hole 2 through a fine hole 11. This phenomenon can be confirmed from the initial small peak of a signal from an optical probe provided near the small hole. When the value of current has arrived at about 20 KA after about 10 mus, new arc discharge is generated at a place whereat the fine hole 11 between rail electrodes 1, 1 is located and the current of the line explosion circuit is attenuated suddenly simultaneously with the generation of the arc discharge whereby the total current is shifted to an arc discharge current quickly. An arc discharge plasma 13 becomes a plasma armature moving with a speed of about 2.5-3.0 Km/s which can be understood from the optical probe signals of respective positions.

Filed: 1992-04-22
Abstract: PURPOSE:To prevent generation of hunting phenomenon wherein increase, decrease and control of a paddy feeding control valve are frequently repeated by suppressively acting a spring when a sensor plate for detecting thickness of a grain layer moves by gravity to one direction from the neutral position. CONSTITUTION:A sensor plate 5 is provided which detects thickness of a grain layer b7 being brought into contact with the upper surface of the grain layer in the inside of a rotary sorting cylinder 2 and being vertically moved. A spring 44 is suppressively acted on both of transfer to one direction based on gravity of the sensor plate 5 from the neutral position and of transfer to the other side resulting from pushing of the grain layer. Thereby transfer to the decrease detection side and the increase detection side of grain from the neutral position is inhibited. Timing of decrease and increase control is delayed for a paddy feeding control valve 42. The socalled hunting phenomenon is prevented wherein the valve 42 is frequently increased, decreased and controlled. Grain is stably sorted while preventing increase and decrease of thickness of the grain layer.
