Title: Production of casting mold
Inventor: OOWADA YOSHIROU
IPC: B22C9/02
Filed: 1982-10-26
Abstract: PURPOSE:To decrease the generation of any casting defect by adding an oleic acid to sand particles for a casting mold kept at a specific temp., mulling the particles and molding the same to an intended shape then cooling the mold to a specific temp. CONSTITUTION:An oleic acid or dioxane is added to sand particles for a casting mold kept at a temp. higher than 30 deg.C and the particles are kneaded. The kneaded sand is filled in a pattern and is molded to an intended shape, whereafter the molding is cooled to the freezing temp. of the oleic acid or dioxane or below to harden the casting mold. Since the melting temp. of the oleic acid is 14 deg.C, the freezing is easier than the case in which water is used, and the casting mold after the freezing is hardly melting and is easy to handle. A binder of an org. material is used and since no water exists, less defects are generated in the casting.

Title: Mask and pattern forming method using this mask and semiconductor device
Inventor: IMAI AKIRA
IPC: G03F1/30
Filed: 1990-07-18
Abstract: PURPOSE:To expand such a range of phase shifter film thicknesses as to impart a permissible phase difference and to solve the various problems associated with phase deviations and fluctuations by determining the refractive index at the exposing wavelength of a transparent material so as to satisfy a specific relation. CONSTITUTION:The refractive index n1 at the exposing wavelength of the phase shifter is so determined as to satisfy at least the relation m1/(m1-1)x0.98<=n1<=m1/(m1-1)x1.02 (where m1 is >=2 natural number). The relation between the phase difference introduced by the phase shifter of the mask and the film thickness of the phase shifter is as shown in Fig. when calculated. The permissible range of the film thickness is expanded by using the condition at the point a if the permissible ranges delta da and delta db of the film thicknesses of the case the condition to attain 180 deg. phase difference exists at the point a and the case the condition exists at the point b deviated from the point a are compared. The permissible range of the film thickness of the phase shifter is expanded in this way and the various problems, such as deterioration of optical images, occurring in the phase deviations or fluctuations are solves.

Title: Non-hit transmission method for digital radio equipment
Inventor: OGUSHI KOJI
IPC: H04B1/74
Filed: 1989-07-20
Abstract: PURPOSE:To prevent hit of a line generated in switching to a spare machine by sending the output of both a machine in current use and the spare machine as separate polarized waves, respectively, receiving both polarized waves with the same polarized wave on one side as that of the machine in current use at a reception side, and setting a ratio at a value not affecting system performance. CONSTITUTION:In an ordinary operation, the output of a transmitter 10 in current use is sent from a radiator for vertically polarized wave, and also, the output from a spare transmitter 11 is sent simultaneously from a radiator for horizontally polarized wave. At the reception side, two waves of vertically polarized wave and horizontally polarized wave from a transmission side are received with the radiator of a parabolic antenna 16, and is received with a receiver 12. When a reception input level from a spare machine side is assumed as U and the reception input level from a machine in current use side as D, D/U can be set at a value not affecting the system performance by using the quantity of identification of antenna cross polarization, and both signals are always received. Thereby, reception input from the transmitter of the spare machine can be obtained even when a fault occurs in the machine in current use and transmission hit occurs.

Title: Manufacture of silver oxide battery
Inventor: MURAMATSU YUKIO
IPC: H01M4/08
Filed: 1982-10-27
Abstract: PURPOSE:To obtain a silver oxide battery having an excellent reliability during preservation by preventing a separator from directly contacting silver oxide by reducing the surface of a positive mixture subjected to secondary press by means of a reducing matter so as to form a silver metal layer. CONSTITUTION:A positive pellet formed by subjecting positive mixture powder to pressure molding, is subjected to secondary press in a positive case 4 thereby obtaining a positive mixture 1. Next, the surface of the positive mixture 1 is treated with a reducing matter such as formalin solution having a viscosity of 30-500 centipoises so as to form a silver metal layer 2 over the surface of the positive mixture 1. The proportion of the silver metal layer 2 is adjusted to 3- 10wt% of the total amount of silver oxide. According to this method, there is no possibility that cracks are caused on the silver metal layer 2 formed on the surface of the positive mixture 1 and that silver oxide appears on the surface of the positive mixture. As a result, there is no possibility of a separator 5 deteriorating due to its contact with silver oxide, thereby the preservation characteristic of the battery is stabilized.

Title: Vessel for diffusion of impurity
Inventor: MATSUMOTO YOSHINARI
IPC: H01L21/22
Filed: 1985-08-29
Abstract: PURPOSE:To prevent the occurrence of disturbance of a surface after diffusion, by providing a vessel with a space which communicates with a wafer accomodating space through slender holes and in which a fitting portion is held when a cover vessel is put on. CONSTITUTION:A vessel 1 and a cover vessel 12 are disposed separately in a reaction tube 20, and then the inside of the tube 20 is replaced by H2. Thereafter the vessel 11 is heated. On the occasion, the temperature of the cover vessel 12 is controlled, and the vessel is kept separated from the vessel 11 so as to prevent the thermal decomposition of a GaAs substrate 16 and the vaporization of impurity Zn101. After a Ga solution 14 is saturated with As, a sealing pipe 22 is removed and the cover vessel 12 is put on the vessel 11. At that time, an atmosphere surrounding the GaAs substrate disposed in a space closed up by the vessel 11 and the cover vessel 12 is filled up rapidly with a vapor phase containing Zn vapor which is thermally equilibrated with the Ga solution 14. Since the GaAs substrate 16 is set in the thermally- equilibrated atmosphere in a sealing vessel which is determined only by temperature, the state of the surface thereof is not varied, and thus the diffusion of Zn free from the occurrence of a stoichiometric defect can be effected.

Title: Intake pipe in internal combustion engine
Inventor: YAOITA AKIO
IPC: F02M31/135
Filed: 1988-07-28
Abstract: PURPOSE:To make icing resistance so better by forming an intake pipe with a plastic material containing conductive materials, while making an electric current flow in this intake pipe. CONSTITUTION:At the time of running of an engine in conditions that its ambient temperature is relatively low but high in humidity as in Nov., Dec., or Mar., Apr. and so on, a driver makes an electric current flow into an intake pipe 8. With this energization, since conductive materials are contained in a plastic material forming this intake pipe 8, the intake pipe 8 is subjected to self-heating as a whole, thereby making temperature in the intake pipe 8 go up. Consequently, even if receiving carburetor latent heat of fuel, the temperature of the intake pipe 8 itself is in no case lowered to less than 0 deg.C, as well as even if humid air containing humidity of oversaturation flows in the intake pipe 8, ice is in no case formed on an inner wall of the intake pipe 8, thus icing is completely checkable.
