Abstract: PURPOSE:To enable manufacturing a semiconductor film composed of beta-SiC(111) heteroepitaxial film having satisfactory semiconductor characteristics such as excellent smoothness and little defects accompanying mosaic-making, APD, etc., by using hydrocarbon gas substituted by one chlorine atom or more as carbon source raw material gas. CONSTITUTION:When beta-SiC heteroepitaxial film is formed on a silicon substrate 3 by thermal decomposition method, a hydrocarbon gas substituted by one chlorine atom or more is used as carbon source raw material gas. For example, after Si(111) substrate 3 has been set on a graphite susceptor 2 in a reaction tube 1 and the reaction tube l has been exhausted to about 10<-7>Torr H2 is introduced to keep the pressure in the reaction tube at 760Torr. Then, after the susceptor has been heated to 1200 deg.C by induction heating, HCl, gas is introduced to remove an oxide film on the surface of the Si substrate, and after the temperature of the susceptor has been once lowered to 600 deg.C and less, CH3Cl is introduced and the susceptor temperature is raised again. Then, when the temperature reaches 1350 deg.C, SiH4 is introduced and the rate of flow is set so that the C/Si ratio in the raw material gas becomes 2.5.

Title: Integrated light source of semiconductor laser and optical modulator, and its manufacture
Inventor: YAMAZAKI HIROYUKI
IPC: G02F1/025
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To improve uniaxial mode oscillation yield, by restraining a kink mode peculiar to this structure which is caused by the waveguide thickness change between a semiconductor laser region and an optical modulator region. SOLUTION: When a semiconductor laser and an optical modulator are formed on a substrate 1, semiconductor layers 8-12 are grown by a selective MOVPE method using a growth blocking mask 6. In a transition region of 120μm, the waveguide thickness gradually changes between a semiconductor laser region 3 and an optical modulator region 4. As to the transition region, the uniaxial mode oscillation yield deteriorates in about 40μm of the optical modulator region 4 and in about 20μm of the semiconductor region 3. The sum 60μm corresponds to 50% of the transition region.  In order that a diffraction grating 2 may not be formed in the domain of 60μm, the diffraction grating 2 is formed in the region (about 42% of the transition region) in the side of the semiconductor laser region 3 which excepts the part from the position where the width of the growth blocking mask 6 changes to the position entering 30μm.

Title: Optical amplifier
Inventor: MAGARI KATSUAKI
IPC: G02B27/28
Filed: 1988-09-30
Abstract: PURPOSE:To solve the problem of a gain difference generated between longitudinal and lateral polarized waves and to obtain an optical amplifier having no polarized plane dependency by separately introducing the longitudinal and lateral polarized waves by a polarization beam splitter, and optically amplifying them independently. CONSTITUTION:When a light of an arbitrary polarized wave is injected from a boat X into a polarization beam splitter 1, the lateral polarized component of the light is transmitted through the splitter 1 to an optical amplifier 3 and amplified. The amplified lateral component is rotated at +45 deg. by a Faraday rotor 5, further reflected by a total-reflection mirror 7, the polarizing plane is again rotated further at +45 deg. by the rotor 5, and varied to the longitudinal polarized wave component. The longitudinal component is again amplified reversibly by the amplifier 3, reflected by the splitter 1, and advanced to a boat Y. On the other hand, the longitudinal component of the incident light from the boat X is reflected by the splitter 1, guided to an optical amplifier 2, and amplified. Thus, optical amplifying characteristic having high gain and no polarization plane dependency is obtained as compared with the optical amplification of a normal single optical amplifier.

Abstract: PURPOSE:To prevent an acceleration pump from operating uselessly, in an engine provided with a carburetor for supplying liquid fuel and a carburetor for supplying gaseous fuel, by making an acceleration pump operating mechanism for the liquid fuel carburetor ineffective when a liquid fuel is used. CONSTITUTION:Liquid fuel is fed to a venturi 2a in a carburetor 1 from a float chamber 5, and an evaporated fuel supply carburetor is disposed upstream of the afore-mentioned carburetor, either one of both carburetors being used as necessary. A piston 25 in accerelation pump 23 in the liquid fuel carburetor 1 is actuated in association with a throttle valve 3a through a lever 30, links 31, 33, lever 32 and rod 27. When a gaseous fuel carburetor is used while the liquid fuel carburetor 1 is not used, a lock lever between the link 33 and a lever 32 is released from a pin 39 so that the pin 39 is allowed to move in an elongated hole 34 in the lever 32, and therefore, even if the throttle valve 3a is opened and closed, the acceleration pump 23 does not operate.

Inventor: HASHIDA TAKU
IPC: F16L59/04
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To obtain a heat insulating foam having high heat insulating property by early fixing carbon dioxide in a heat-insulating foam. SOLUTION: This heat insulating foam comprises an expandable urethane resin composition containing an epoxide and a carbonate component produced by reacting the epoxide with carbon dioxide and satisfies the formula (molar concentration of epoxy group)>(molar concentration of carbon dioxide + molar concentration of isocyanate group) in the relationship of average molar concentrations of carbon dioxide, isocyanate group and epoxy group. The production of the foam is carried out by mixing at least one of a retardant activation type resinifying catalyst composition and a retardant activation type resinifying material composition with raw materials of the urethane resin.  Thereby, advancing degree of the resin forming reaction is increased and the amount of isocyanate group left immediately after the urethane resinification reaction is decreased and fixing reaction of carbon dioxide due to the epoxide is promoted.

Title: Loop type heat pipe hot water generator
Inventor: TAKEDA HISANOBU
IPC: F28D15/02
Filed: 1988-09-29
Abstract: PURPOSE:To prevent a dangerous condition from being generated by a boiling action of accumulated water after termination of feeding of hot water by a method wherein a water passage in a heat exchanging part is connected between a water amount adjusting valve and a hot water feeding port and a natural water discharging structure is attained in which water supplied from a water source through a water amount adjusting valve is made to flow out from an upper part to a downward part under a heat difference between an inlet port and an outlet port in the water passage and further a vacuum breaker is connected to the water passage. CONSTITUTION:A water amount sensor 26 is fixed to a water supplying pipe 21 between a water amount adjusting valve 22 and a heat exchanging part 13, and an air-vent pipe 28 is connected to a downstream side of the water amount sensor 26 through a vacuum breaker 27. This vacuum breaker 27 operates such that a valve member 27a is lifted up under a water pressure within the water supplying pipe 21 to close a communication between the air-vent pipe 28 and the water supplying pipe 21. As the hydraulic pressure within the water supplying pipe 21 is eliminated, it is dropped by its own weight to cause the air-vent pipe 28 to communicate with the water supplying pipe 21 and then to allow air to be flowed into the water supplying pipe 21 from the air-vent pipe 28 communicating with the surrounding atmosphere.
