Title: Side seal of rotary piston engine
Inventor: YAMAMOTO JUNICHI
IPC: F01C19/08
Filed: 1984-12-26
Abstract: PURPOSE:To improve initial property of running-in and resistance to wear, by a method wherein a groove-like hardened part is formed in the central part in the direction of thickness of an end surface brought into slide contact with the side housing of a side seal by melt contraction. CONSTITUTION:Only a central part in the direction of thickness is molten and hardened by the use of a beam heat source, such as electronic beam, laser beam, without melting both ends in a longitudinal direction of a side seal slide surface. A molten chilled part is dented to form a grooved part, and the width of the groove is about 1/5-4/5 the thickness of the side seal. This improves both initial property of running-in and long-term resistance to wear, and enables gas sealing ability to be provided in an excellent manner for a long time commencing with the primary stage of the used.

Title: White smoke preventive device
Inventor: MATSUTANI YOSHIO
IPC: F23J15/00
Filed: 1985-12-10
Abstract: PURPOSE:To prevent an energy loss and prevent a generation of white smoke in a wet type discharging gas processing device by a method wherein an amount of discharging gas, a temperature and a humidity of the discharging gas and a temperature and a humidity of surrounding atmosphere are supervised to adjust an intake amount of air, and at the same time a heating amount is adjusted. CONSTITUTION:When an outlet gas at a humidity reduction part (T3, H3) G3m<3> and heating air (T2, H1) A1m<3> are mixed with each other, the mixture gas occupies a point D(T4, H4) corresponding to G3 vs A1 on a B-C line. In this case, when the mixture gas is discharged from a chimney at its mixture gas temperature, the mixture gas is cooled with air outside the chimney and its temperature is decreased from T4-T1. In this case, it crosses a saturation vapor pressure curve 7 as indicated by a dotted line and it goes above the curve, so that moisture content is condensed and the gas becomes a white smoke and is discharged out of the chimney. Thus, the mixture gas is reheated up to TE of a point E (HE, TE) which is an intersection of H4 and a white smoke preventive condition equation H=aT+b, thereby the smoke does not become a white smoke and the gas can be discharged.

Filed: 1986-11-21
Abstract: PURPOSE:To accelerate the positioning of a stepping motor by providing a switch for short-circuiting phase exciting windings at a predetermined timing thereby to advance the attenuation of the vibration at the time of positioning. CONSTITUTION:When a rotor 1 is stopped in the state that an A'-phase is excited, at least one of A-, B-, B'-phase switches 14b, 15b, 17b of the phase which is not excited is turned ON to short-circuit the exciting coil.

Title: Remote measuring method of tire pressure
Inventor: TANAKA MASAICHI
IPC: G01L17/00
Filed: 1990-10-19
Abstract: PURPOSE:To learn accurate tire pressure speedily in any case by connecting a control line to the low pressure side for a short period of time through operation of a pressure control valve before measurement so as to measure tire pressure accurately and speedily. CONSTITUTION:A pressure control valve 355 is in the neutral position and a pressure discharge valve 358 is in the first position at the time of non- operation. Therefore, a control line 351 is shut off from a compressor 352 and an air cylinder 354. On the other hand, the atmospheric pressure is introduced into a tire pressure adjusting valve 300 from the control line 351 to block a passage. Consequently, the inside of a tire 101 is shut off from the outside, and pressure at that time is maintained. I this case, the same operation as that at the time of pressure reduction control is carried out intentionally to shorten equilibrium reaching time after pressure is increased and controlled. That is, after increase and control of pressure ends, the pressure control valve 355 is not only returned to the neutral position from the first position, but also moved to the second position for a short period of time only. Thus, pressure of air in the control line 351 is instantaneously released in the atmosphere via the pressure control valve 355 and a muffler 361.
