Patent JP-H02306620-A (JP)
Title: Manufacture of semiconductor device
Inventor: ITO TAKASHI
IPC: H01L21/22
Filed: 1989-05-20
Abstract: PURPOSE:To uniformly take out impurity outside semiconductor with superior reproducibility, and introduce impurity into the semiconductor at a low temperature, by projecting radio waves having energy larger than or equal to the bonding dissociation energy on a semiconductor substrate, and changing the distribution of impurity contained in the substrate. CONSTITUTION:A semiconductor substrate 1 is irradiated with radio waves 2 whose energy is larger than or equal to the bonding dissociation energy, and impurity atoms are outwardly diffused by releasing the impurity atoms in the semiconductor from the bonded state. At this time, it is effective that the atmosphere is kept at a vacuum state or a reduced pressure state, and the substrate 1 is heated at a temperature wherein heat is not dissipated. As to the radio waves 2, synchrotron radiation ray SR is practically used because of large energy. When the atmosphere is made to contain impurity while the radio waves 2 is projected, Si-Si bond is cut by the same reason as the case of outward diffusion, e.g. light irradiation. Thereby impurity can be uniformly taken out from semiconductor with superior reproducibility, and introduced into the semiconductor at a low temperature.

Abstract: PURPOSE:To eliminate a variance of a mixing ratio, and to eliminate a chance for mixing a foreign matter by mixing in a mixing tank plural objects whose capacity has been measured by a measuring device, and supplying this mixed substance to a demand part from a supplying tank. CONSTITUTION:An undiluted liquid 16 is injected into an inner tank 13 of a measuring tank 12 from an undiluted liquid tank 15.

Title: Manufacture of positive plate for lead storage battery
Inventor: HIRASAWA IMAKICHI
IPC: H01M4/20
Filed: 1982-07-22
Abstract: PURPOSE:To enhance the utilization rate of the active material, and increase the life performance of a positive plate by causing lead powder containing minute Teflon grains to adhere to the surface of a base plate consisting of a grid made of a lead-calcium alloy or the like, being followed by packing a paste into the base plate. CONSTITUTION:After Teflon grains with 0.2-0.4mum diameter are homogeneously dispersed in a solvent by use of a non-ionic surface active agent to prepare a dispersion liquid, lead powder is added to the liquid to make a slurry. Next, a base body consisting of an antimony-free grid made of a lead-calcium alloy or the like, is dipped in the slurry to cause the slurry-like matter to adhere homogeneously to the surface of the base body. After that, the solvent is evaporated, then a paste is packed into the base body, thereby making a positive plate. As a result, the porosity is decreased by either filling the fine holes or decreasing the diameter of the fine holes of the active material with Teflon grains, and diffusion of H2SO4 near the base body can be obstructed. Consequently, the life performance of the positive plate can be greatly improved by preventing any overuse of the active material.

Title: Refrigerating cycle with by-pass conduit for vehicle
Inventor: HIROTA HISATOSHI
IPC: F25B41/04
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To exercise a heating effect under a circumstance where air temperature is remarkably lowered after leaving a cooling mode by setting a capacity control means so that capacity of a compressor starts to decrease from the maximum state at lower than specific suction pressure under a state where a refrigerant passes a condenser without passing through a by-pass conduit. SOLUTION: When suction pressure of the compressor 10 is lowered in this device a capacity control valve 20 is provided for capacity control of a capacity variable compressor 10 so that capacity is correspondingly and automatically reduced. Therefore, under a circumstance where air temperature is extremely low, a refrigerant reserved in a condenser 52 is collected on the side of an evaporator 54 and an accumulator 56 and it is possible to provide a sufficient heating effect by the evaporator 54 in an auxiliary heating mode to flow the refrigerant to a by-pass conduit 55.  Thereafter, it is possible to provide the sufficient heating effect in the evaporator 54 in a range of more than about -10 deg.C when the capacity of the variable capacity compressor 10 is made to start to decrease from the maximum state at less than 2 atmospheric pressure (absolute atmospheric pressure) of suction pressure.

Title: Fuel injector
Inventor: NAKAGAWA TOYOAKI
IPC: F02D41/20
Filed: 1983-07-14
Abstract: PURPOSE:To maintain the injection time and quantity of fuel at appropriate values when its injection ratio is lowered, by providing a means for modifying at least one of the drive time and period of a different solenoid valve on the basis of the detection signal of an injection ratio control state. CONSTITUTION:A signal from a displacement sensor 57 for a solenoid valve 53 is converted into a voltage signal V1 by a processing circuit 58. The voltage signal V1 is sent to a discriminator 59 to generate a high-level signal S1 when the valve 53 is closed, or generate a low-level signal S1 when the valve is open. Calculation circuits 60, 61 compute an optimal injection time and an optimal injection quantity on the basis of an injection control signal generated by a control circuit 56 and corresponding to the condition of operation. A low injection ratio circuit 61 sends out a signal S3 earlier than a high injection ratio circuit 60, in such a manner that the output of the signal S3 lasts for a long period. When the level of the output signal S1 of the discriminator 59 is high, a switch 62 selects a signal S2. When the level of the output signal S1 is low, the switch 62 selects the signal S3. The selected signal S2 or S3 is applied to a solenoid valve 40 through an amplifier 63 to close the valve. For this reason, the delay of injection start time and the reduction of injection quantity are prevented when the injection ratio is lowered, to maintain an appropriate operation.
