Title: Synchronization control system for terminal station
Inventor: SHIMIZU TAKAFUMI
IPC: H04M3/00
Filed: 1977-11-04
Abstract: PURPOSE:To make possible the data transmisstion even when the reception field is fluctuating and thus to enhance the reliability for the mobile radio system by providing the local allotment time counting function to the mobile station. CONSTITUTION:When one of plural units of start pulses added with the sequential number given from the base station is received in a correct way, counter 15 is started. And the allotment time of the own station is counted based on the sequential number to carry out the data transmission within the allotted time. In case the next start signal cannot be received from the base station, the data is transmitted repetitivery with every system cycle time from the data tranmsission time based on the counting of the system cycle time via system timer 17. After this, counter 15 and timer 17 are reset when the start pulse is received correctly. Thus, the local allotment time is counted again.

Title: Vapor growth device
Inventor: IKUWA MITSUAKI
IPC: H01L21/205
Filed: 1990-05-22
Abstract: PURPOSE:To allow the easy imposing of substrates for growth on a susceptor by using plate jigs having collar parts on the peripheral edges in such a manner that the substrates for growth can be imposed on the imposing parts of the susceptor. CONSTITUTION:The jigs 9 for holding the substrates are formed of, for example, quartz and have a rectangular shape as a whole. Each jig is formed with collar parts 9a, 9b, 9c respectively in both side part and lower side part and a U-shaped frame is constituted of the collar parts 9a to 9c. The top side part of the jigs 9 has not collar part and is formed with such a tapered surface 9d as to be lower toward the rear surface. The tapered surface 9d formed in the upper side part of the jigs 9 facilitates the imposing and taking out of the substrates. The step from the surface of the susceptor 2 is eliminated if the jigs are so imposed on the susceptor 2 that the tapered surfaces 9d are positioned upward. The flow of gases from above is thereby smoothed and the thin films having good uniformity are formed.

Title: Optical temperature detector
Inventor: OOSHIMA SHIGERU
IPC: G01K11/00
Filed: 1979-10-16
Abstract: PURPOSE: To obtain an optical temperature detector of explosion-proof structure having a high resistance to the noise and a stable working, by vibrating the diaphragm whose resonance frequency varies by the temperature with the electric pulse obtained by giving a photoelectric conversion to the optical energy and sensing optically the resonance frequency.  
     CONSTITUTION: The optical pulse sent from the light source 2 which received the output of the pulse oscillator 1 passes through the optical waveguide path 3 to be branched into two routes 45 and 49 via the optical distributor 4. One light passing through the route 45 is turned into the pulse voltage through the photoelectric transducer 5 to give a displacement to the piezoelectric element 6. Thus the diaphragm 8 is vibrated by the optical energy of the optical pulse. On the other hand, the other light passing through the route 49 passes through the optical waveguide path 49' within the diaphragm 8 and receives a forced modulation via the lens 9 to be sent to the optical detector 11. And the light in the detector 11 is then converted into the electric signal to be sent to the frequency counter 12. Thus the resonance frequency of the diaphragm 8 is detected. Furthermore, a time-averaging is given to the measured value through the averaging circuit 13 to obtain a higher accuracy. Based on the value of the resonance frequency thus obtained, the corresponding temperature is obtained.

IPC: F23D11/02
Filed: 1986-06-10
Abstract: PURPOSE:To quickly vaporize and burn fuel completely in a combustion chamber, by constituting a combustion cylinder of porous ceramics of low thermal expansion coefficient. CONSTITUTION:A combustion cylinder 11 consisting of a carburetion chamber 7 and a combustion chamber 6 is made of porous ceramics of low thermal expansion coefficient. A bulkhead 8 which partitions the carburetion chamber 7 from the combustion chamber 6 and the carburetion chamber 7 provided with a material 10 of high thermal conductivity at their bottoms. A porous ceramic material 25 of low thermal expansion coefficient is fixed on the casing plate 5 of a carburetion chamber 7. If liquid fuel is not completely vaporized by a carburetion glow plug 3, oil droplets will mix with vaporized fuel when the vaporized fuel is injected from an injection port 23. The oil droplets collide against the ceramic material 25, turning into fuel liquid, dripping down to the bottom of a combustion chamber 6. But when the combustion cylinder 11 is heated up to high temperature, the fuel liquid dripping down and permeating into the bottom are vaporized to be burned in the combustion chamber 6. The materials 10 transfer combustion heat to the side of a carburetion chamber 7, so that vaporization of fuel liquid gathered at the bottom of a combustion cylinder 11 is promoted. The material 25 also promotes vaporization of fuel liquid as well as to prevent the carburetion chamber 7 from cooling.
