Title: Cassette transfer apparatus
Inventor: SHIROO KAZUHIRO
IPC: H01L21/68
Filed: 1989-04-26
Abstract: PURPOSE:To avoid the intervention of the misoperation of an operator in an automatic manufacturing line of semiconductors by a method wherein a cassette is fixed when the cassette is transferred. CONSTITUTION:When a cassette 1 is at a replacing position, the signal of a cassette replacing position detecting sensor 3 is in an ON-state. As a replacing operation is performed by an operator and a robot at that time, a clamping force is not generated. If, for instance, an etching sequence is started, a cassette base 5 is made to descend. Therefore, the output signal of the sensor 3 is turned OFF and, following the signal, a clamping mechanism 4 clamps the cassette 1. When the etching sequence is finished and the cassette 1 reaches an upper- limit position again, the output signal of the sensor 3 is turned ON and the clamp is released. By driving the clamping mechanism 4 following the signal of the sensor 3 as described above, the misoperation of the operator can be avoided mechanically.

Filed: 1992-04-23
Abstract: PURPOSE:To achieve the high optical output of the title laser device by a method wherein a strain-relaxing layer is formed near an active layer situated in an internal region excluding an optical-output-side edge region. CONSTITUTION:In an active layer 8, an undoped GaAs barrier layer 5, an undoped InyGa1-yAs strain quantum-well layer 6 and an undoped GaAs barrier layer 7 are laminated in this order. The InyGa1-yAs strain quantum-well layer 6 has a lattice constant which is larger as compared with that of a GaAs substrate. As a result, it is provided with a compressive strain. A p-type InxGa1-xAs (where 0<x<y) strain-relaxing layer 9 is formed in a region excluding optical- output-side edge regions A, C, i.e., in an internal region B, out of the upper part of the GaAs barrier layer 7. Thereby, the compressive strain of the active layer situated in the internal region B is relaxed, but the compressive strain of the active layer ion the optical-output-side edge regions A, C is hardly relaxed. As a result, the optical-output-side edge regions A, C are regions which do not absorb a laser beam and can prevent COD from being generated.

IPC: C02F1/58
Filed: 1980-07-30
Abstract: PURPOSE: To simply purify fluoride ion-contng. waste water within a short time, by adding a water-soluble calcium compound to the fluoride ion-contng. waste water in the presence of phosphate ion, while adjusting the pH value of the waste water.  
     CONSTITUTION: In the disposal of fluoride ion-contng. waste water, for instance, discharged from a glass-making process, the waste water is adjusted at pH4 or lower in the presence of phosphate ion, and then a water-soluble calcium compound, e.g. calcium hydroxide, is added to the waste water. In this case, if the pH value of the waste water is lower than 6, the waste water is readjusted at a level higher than 6. Consequently, a difficulty water-soluble fluoride complex salt is formed. The formation of the salt is very rapid, and the salt is settled and separated. As a result, the fluoride ion-contng. waste water can be purified in a simplified process within a short time.

Abstract: PURPOSE:To efficiently separate sewage into solid and liq. without clogging a filter medium by laying the filter medium over the large-diameter opening of a conical or pyramidal centrifugal separation chamber at larger than a right angle to the axis of rotation in the centrifugal separation chamber. CONSTITUTION:A rotation shaft 3 is rotated to integrally rotate a supply box 8, a housing 1, the filter medium 11, etc. The raw liq. to be treated supplied to the supply box 8 is supplied into the centrifugal separation chamber 2 from a supply port 9, then pressed on the inner surface of the chamber 2 by the centrifugal force, and moved along the inner surface toward the large-diameter part 2a of the chamber 2. Consequently, the solid component D in the liq. is deposited on the large-diameter part 2a, and the water E is passed through the filter medium 11 and discharged. At this time, since the solid component deposited on the inner surface of the filter medium 11 is forcibly moved to the large-diameter part 2a of the chamber 2 by the centrifugal force, the filter medium 11 is also cleaned by the centrifugal force and hardly clogged.

Title: Pasted lead storage battery
Inventor: TOKUNAGA AKIO
IPC: H01M4/62
Filed: 1984-05-23
Abstract: PURPOSE:To reduce the incidence of early degradation of the capacity of a pasted lead storage battery caused by its repeated deep charge-and-discharge by using a positive plate prepared by packing a lead-calcium-system alloy grid with a storage battery paste containing anisotropic graphite. CONSTITUTION:A lead powder containing 25% of metallic lead is mixed with 0.5wt% of anisotropic graphite with particle diameters of 200-1,200mum. The thus prepared mixture is then kneaded with dilute sulfuric acid to prepare a positive paste with a density of about 4.0g/cm<3>. After the positive paste is packed into a lead-calcium-system alloy grid to make a positive plate, a pasted lead storage battery is constituted using the positive plate. As a result, the anisotropic graphite contained in the positive paste expands during battery charging and the expansive force presses the positive plate, thereby increasing the binding between the grid and the active material. Moreover, the good conductivity of the interlayer compound of graphite suppresses the polarization of the battery during its discharging. Accordingly, it is possible to prevent any early degradation of the capacity which might be caused by deep charge-and-discharge cycles.

Title: Manufacture of oxide film of semiconductor
Inventor: TORIKAI TOSHIHISA
IPC: C23C8/10
Filed: 1978-08-28
Abstract: PURPOSE:To prevent defects and dislocation due to thermal strain, by irradiating a semiconductor under an atmosphere of oxgygen or oxygen-containing gas with light of such energy density as to instantaneously melt the surface of the semiconductor, so that an oxide film is produced on the irradiated part only. CONSTITUTION:A ruby laser light source 1 for a wavelength of 0.694mum is installed. The oxygen gas in a treatment chamber 9 is maintained at 20 atmosphere. The energy density of the output light of the ruby laser light source is set at 2.0 joule/cm<-2> per pulse. The beam of the light is converged to a diameter of 50mum by lenses 3-5 and irradiated through a quartz window 6 upon the surface of a silicon piece 7 set in the treatment chamber 9 so that the surface of the irradiated part is instantaneously molten. As a result, an SiO2 film of about 600Angstrom  in thickness is produced. If the time of the laser light irradiation is kept constant and the pressure of the atmosphere of oxygen is altered, the thickness of the SiO2 film is changed. Because the temperature of the silicon piece is raised at the irradiated only, the defects and dislocation are very little.

Abstract: PROBLEM TO BE SOLVED: To reduce the frequency of cleaning inside a cell and to lighten the load of maintenance control by forming the cell for sample liquid in a double structure, using the cell for the high-concentration cell and the cell for the low concentration by switching, and lengthening the period of use of the low- concentration monitor. SOLUTION: In the case of high-concentration monitor after disassembling cleaning in a steam turbine, sample liquid enters a cell 16 from a water supply hole 18, and measurement is performed. Then, the liquid is exhausted from an water exhausting hole 19. However, the high-concentrations monitor is quickly contaminated by minute particles of iron in the sample liquid. Therefore, the supply of the sample liquid from the water supply hole 18 is stopped at this point. The cell 16, where the cell 6 and a water-exhausting hole 19 integrally form one body, is removed. Then, a separate flange 17 is attached, and the low-concentration sample liquid is supplied into the cell 6 from a water supply hole 7. The low-concentration monitor is operated as the monitor in normal operation times. Thus, the frequency of cleaning inside the cell 6 can be reduced by a large extent.
