Title: Detector of transporting material
Inventor: YONEZAWA HIDENOBU
IPC: B65G11/02
Filed: 1990-01-26
Abstract: PURPOSE:To simply and surely detect even commodities of different dimensions with a detector of transporting material such as hot formed ring-shaped commodities by providing it with a detecting bar whose lower end contacts a work on a shoot and swings whose shielding plate provided at its upper end shields the light between a light projector and a light interceptor. CONSTITUTION:When the material at the most rear part of materials W sent onto a shoot 3 passes a detecting bar 7 and stays, the lower end of the detecting bar 7 is pushed upward by the material W while a supporting bar 9 swings to the right direction in the attached drawing to insert a shielding plate 8 between a light interceptor 11 and a light projector not shown in the drawing and shut off a light, thereby stay of the material W is detected and supply of material is temporarily stopped. When the stay is gone, the detecting bar 7 swings downward, the shielding plate 8 withdraws from the light shielding position to resume material supply. Because of this constitution, materials whose sizes are different can be surely detected with simple construction.

Filed: 1983-02-04
Abstract: PURPOSE:To enable to measure the depth of impurity level by a method wherein a Schottky junction is formed by putting an electrolyte in contact with the surface of a semiconductor sample, the capacitance of the junction is detected while the surface is irradiated with a monochromic light, and the impurity level is measured by the dependency of obtained carrier concentration on wavelengths. CONSTITUTION:The light from a light source 11 emitting the monochromic light is made incident to a spechtroscope 12, and a photo transmitting type etching bath 13 filled with tiron solution 14, the electrolyte, is irradiated with the light 10 changed into a spectrum. The semiconductor sample 15 composed of the crystal of GaAs, etc. is made to abut against the aperture of the bath 13 provided on the side opposite to the irradiation, and thus the surface of said sample is uniformly wetted with the tiron solution 14. Next, the capacitance of the Schottky junction generated thereby is measured by a C-V measuring instrument 16 consisting of a detecting probe 17, an amplifier, and a recording meter. Thus, the expansion of a depletion layer at the junction and the spectrum of the carrier concentration at the ground point of the depletion layer are obtained, and accordingly the impurity level is estimated.

Title: Method for working surface of metal mold for resin molding
Inventor: KAWABATA SHIGEO
IPC: C25D7/00
Filed: 1987-01-30
Abstract: PURPOSE:To produce a metal mold for resin molding having a high accuracy mirror finished surface at a low cost, by machining a light metal with a dia mond tool to form a mirror finished surface and by forming a very thin Cr film on the surface by plating to increase the surface hardness. CONSTITUTION:A light metal such as a Cu-Al alloy is machined with a diamond tool as a high accuracy machine tool to form a mirror finished surface having 0.03mum surface accuracy. Since the mirror finished surface is soft and is not suitable for use as the surface of a metal mold, a very thin Cr film of about 0.05mum thickness is formed on the surface to increase the surface hardness. Thus, working to the high accuracy mirror finished surface is facilitated and manual mirror polishing can be made unnecessary.

Title: Control system of car air conditioner
Inventor: SUDOU SHINJI
IPC: F24F11/02
Filed: 1980-02-20
Abstract: PURPOSE:To prevent cooling cycle from being overloaded by decelerating an air blower and opening an air mix door at the heater mode side when the intra-car temperature rises higher than at full cooling time. CONSTITUTION:When a command signal which raises the intra-car temperature higher than at full cooler mode is output, a drive circuit 13 is operated and the number of revolutions of an air blower 1 decreases. By decreasing the number of revolutions of this air blower 1, a temperature rise effect is obtained to some extent based on a load. In this stage, since an air mix door 4 is not opened, the cooling air cooled by a cooler cannot be heated by a heater and the load of the cooling cycle of the cooler can be reduced. Then a transducer 11 is actuated and the air mix door 4 is slowly opened. Part of the cooling air is heated by the heater and the intra-car temperature is raised.

Title: Photocatalytic element and device for treating gas containing organic compound
Inventor: MASUDA RYUJI
IPC: B01J35/06
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To efficiently treat gas to be treated without decreasing the throughput of the gas, even when a photocatalyst is fabricated into a corrugated shape by using a reticular material with a specified weave aperture area (numerical aperture) per unit area as a base material and further, fabricating the base material into a corrugated shape in such a way that the ratio between the pitch and the height of the reticular material is equivalent to a specific value or higher. SOLUTION: When the numerical aperture of a base material is 5% or less, the resistance to gas permeation is increased, so that the throughput of gas cannot be augmented. In addition, when the aperture is 40% or more, the resistance to gas permeation is decreased and the borne amount of photocatalyst is reduced. Consequently, it is essential that the numerical aperture be set within the range of 5-40%. Further, the photocatalytic element 1 is formed into a corrugated reticulation through the process of making a glass cloth bear titanium oxide and corrugating this glass cloth. In this case, the ratio between the pitch P and the height H of corrugations is set at 1 or less.  An organic compound contained in gas to be treated is made to flow in through the inlet 3 for the gas of a reaction part 2 and is further made to pass at 60-120 deg. with the center face C of the photocatalyst 1 of a corrugated shape irradiated with light from a light source 4. After this passage, the organic compound is allowed to flow out of an outlet 5 for the gas to be treated.
