Title: Electromagnet for charged particle device
Inventor: HARADA TOSHIHARU
IPC: H01F13/00
Filed: 1988-03-11
Abstract: PURPOSE:To prevent effects of the past excitation history at a low cost by providing a detachable magnetic body for bypassing magnetic flux in a gap forming a magnetic circuit in series with an electromagnet iron core so as to eliminate a remaining magnetic field in the gap to zero. CONSTITUTION:A magnetic body 4 is provided in a gap of an electromagnet consisting of an iron core 2 having an excitation coil 3 applied for bypassing a magnetic flux. By detaching the magnetic body 4 while excitation of the electromagnet, a need of deflecting charged particles is eliminated, and if an exciting power source for the electromagnet is disconnected, a remaining magnetic field is produced by hysteresis phenomenon of the iron core 2. By inserting the magnetic body 4 into the gap then, remaining magnetic flux passes the magnetic body 4 to eliminate the remaining magnetic field in the gap to zero. Effects of hysteresis phenomenon of the iron core can thus be eliminated at a low cost without providing a power source for demagnetizing separately.

Title: Differential pressure responding device
Inventor: ITOU ICHIZOU
IPC: G01L13/06
Filed: 1978-05-12
Abstract: PURPOSE: To obtain a responding device of simple constitution by detecting the stress which correspond to the differential pressure generated in a pressure receiving bar which does not flex and deform.  
     CONSTITUTION: When different pressures from pressure conduit holes 73, 74 are applied to the diaphragms 41, 42 forming pressure receiving chambers 71, 72, the displacement owing to the differential pressure of the connecting shaft 80, in the central hole formed by blocks 21, 22, which is coupled at both ends to the diaphragms 41, 42, is blocked by the pressure receiving bar 81 which is connected to the shaft 80 and does not flex or deform. Thereby, the stress corresponding to the differential pressure is generated symmetrically to the axis of the bar 81 and this stress is detected with the stress detecting means 90 such as piezoelectric element or the like provided to the bar 81, thus the constitution of the differential pressure responding devive becomes simple. Since the stress generated in the bar 81 is symmetrical to the axis, the vibratory differential pressure owing to noise, etc. is offset and the good responding detection is accomplished.

Abstract: PURPOSE:To improve a partial load efficiency by a method wherein a speed changing means fixed to a rotation inputting part of a compressor is changed over to change the turn-down ratio of the compressor. CONSTITUTION:Pulleys 11 and 12 having the same diameter are fixed to a driving rotational shaft 10 of a gas engine. A large diameter input pulley 14 and a small diameter input pulley 15 are fixed in two stages to an input rotary shaft 13 at a compressor Pulleys 11 and 15 and pulleys 12 and 14 are connected by each of belts 16 and 17, thereby a rotation of the gas engine is transmitted to the compressor. A turn-down ratio at the compressor is expanded by changing a rotational ratio between the engine and the compressor. For example, in the case that the number of rotations of the engine is 1000 to 3000rpm (the turn-down ratio of 3), the speed changing means is set in such a way that the rotational ratio between the engine and the compressor is set to have two stages of 1.2 and 1.6, the number of rotation of the compressor becomes 1200 to 4800rpm and the turn-down ratio becomes 4. As a result, it is possible to improve a partial load efficiency.

Title: Evaluating method for shape of plate material
Inventor: TAWARA KOUICHI
IPC: G01B11/24
Filed: 1981-04-16
Abstract: PURPOSE:To evaluate the shape of a plate material by using a linear and a spot light source property in accordance with the characteristics of the surface of the plate material, and then observing the distortion of a reflected image on the plate material surface from a straight line. CONSTITUTION:A linear light source 16 is turnable around a spot light source by a driving device 22. A reflected image 20a of the light source on a steel plate 10 is observed through a TV camera 14 to evaluate the shape of the steel plate 10 by its distortion from a straight line. When the surface of the steel plate 10 is close to a mirror surface and reflection has no reflectivity, the linear light source 16 is turned on and turns to an easy-to-see angle, thereby observing the distortion of the reflected image 20a from a straight line. When the reflection has a little directivity, the short tail 20b of a regularly reflected image 20a of the spot light source 20 is made to coincide with a reflected image of the linear light source 16 and the light source is turned until a clear image is obtained, thereby performing the observation. When the reflection has intense directivity, a long tail 20b is obtained only by the spot light source 20, so this is observed.
