Title: Envelope
Inventor: NISHIGAKI MAKOTO
IPC: B42D15/08
Filed: 1993-06-17
Abstract: PURPOSE:To prevent creases from being made in an envelope fed through a fixing unit such as a copying machine and laser printer by applying a low- friction material to the internal surface of the envelope used on an image forming unit. CONSTITUTION:The internal surface of an envelope front paper P1 is coated with a thin film of silicon (S) to reduce friction between the front paper P1 and back paper P2, thereby preventing creases from being made. A Teflon-one- coated sheet material may also be used with its Teflon-coated surface placed inside so that the front paper P1 and back paper P2 are slippery, having a low friction. The inside face made of a low-friction material makes an envelope have a slippery front paper and back paper with reduced friction, thereby preventing creases from being made in it when it is fed through a fixing unit such as a copying machine and laser printer.

Title: Dominical year, era, and full age ready reckoner
Inventor: INO SHOJI
IPC: G06C3/00
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To use a ready reckoner lifelong and to grasp the years of Buddhist masses and anniversaries by dividing the outer periphery of the disk of an outer wheel which rotates and the outer periphery of the disk of a fixed intermediate wheel equally by 100 and entering era years and ages. SOLUTION: The outer peripheries of the outer wheel disk 1 and intermediate wheel disk 2 are divided equally by 100, and 100 as an dominical year and 100 as an age are indicated. This ready reckoner is fixed at an age of 0 (100) of the intermediate wheel disk 2 directed upward. When the rotary outer wheel disk 1 of the dominical year is set to the age of 0, a person who desires to know how old the person is will see the full age after the birthday and the full age plus one before the birthday. When the year of death of a person is marked on the year wheel, the years of Buddist masses can be found early (namely, the anniversaries of death are entered with the numbers of years which are each one year less than the age).  The Meiji era, Taisho era, Showa era, and Heisei era are shown at the upper stage of the outer periphery of the outer wheel disk 1 and the time after 2000 (the 12th year of the Heisei era) is shown at the lower stage of the outer periphery. Consequently, an age above 100 can be seen.

Abstract: PURPOSE: To increase the temperature efficiency and the heat recovering efficiency of a heat  exchanger, by composing moving fluidized bed fit to the temperature distribution, by arranging  to cross a number of heat transfer pipes to heat recovering and moving fluidized bed at right  angles with the moving direction of the bed, gradually decreasing the number of pipes from  the lower part to the upper, and by arranging pipes to the part facing the side of an inlet port of a fluid in high temperature only, at the top part.  
     CONSTITUTION: The heat transferring pipes 4 are arranged in the heat recovering and moving  fluidized bed B, crossing at right angles with the moving direction of the fluidized bed, and in  the top part of moving fluidized bed B, the pipes are arranged to the side of inlet port 2 for  fluid in high temperature only. The number of pipes are gradually increased so as to fit to the  tendency of an isothermal line of temperature distribution of the layers of powdery grain, and the pipes are arranged to full positions in the lower-most part. By passing through heat transferring pipes 4 from the lower part toward the upper, the fluid in low temperature is to exchange heat with the powdery grain in high temperature only, by the intermediary of heat  transferring pipes 4 in the neighborhood of an inlet port of heat recovering moving fluidized  bed B. Because contact with the powdery grain in low temperature is avoided, the fluid is  prevented from losing its temperature. Accordingly, the temperature efficiency and the heat  recovering efficiency of a heat exchanger of the captioned type is increased.

Title: Covered optical fiber
Inventor: NISHIMURA MASAO
IPC: G02B6/44
Filed: 1983-09-14
Abstract: PURPOSE:To prevent an increase of a transmission loss caused by hydrogen of a covered layer of a quartz compound optical fiber by making the covered layer contain a compound having a reactivity to hydrogen. CONSTITUTION:In a covered optical fiber 10, a covered layer 4 is formed on the outside circumference of a covered layer 2. The covered layer 2 has one or both functions of primary coat and buffer coat, and the covered layer 4 has a protective function whose mechanical characteristic is excellent. When a prescribed compound is contained in the covered layer 2 and/or the covered layer 4, the prescribed compound reacts to hydrogen and comes to catch it, and accordingly, even if a lattice defect exists in an optical fiber, the caught hydrogen cannot invade into its optical fiber 1, by which an OH radical is not generated, therefore, a covered optical fiber whose transmission characteristic is stable is obtained extending over a long period of time in which an increase of a transmission loss is scarcely generated. As for the prescribed compound, namely, a compound having a reactivity to hydrogen, it is desirable to use that of a suit able material quality by adjusting it to a suitable quantity, and an organic peroxide can be exemplified. As for a content of the organic peroxide, 0.01- 5wt% is desirable against the covered layer containing it.

Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To search arriving direction of radio waves of a mobile station in a simple structure by radiating the impulsive radio waves from the mobile station and receiving the radio waves, at a base station having an adaptive array antenna. SOLUTION: A mobile station radiates the impulsive radio waves, and a base station has the adaptive array antennas 401-40n, having plural branches and allocates some of beams of these antennas for searching the arriving radio waves of the mobile station. For instance, all beams that are not capturing or tracking the mobile station can be allocated to the beams for searching the arriving radio waves of the mobile station. Each of these search beams controls the tap coefficient of every branch via a controller 50 to scan a 360-degree service area as long as an omniantenna is used. In other words, the tap coefficients are controlled, as soon as the impulsive radio waves sent from the mobile station area successively searched and a directional beam is formed in the searching direction to capture the mobile station.

Title: Static pressure type support device
Inventor: NISHIMURA KAORU
IPC: F16C32/06
Filed: 1989-06-30
Abstract: PURPOSE:To obtain a static pressure type support device having a higher rigidity by interposing an orifice in which the flow rate of a gas becomes acoustic velocity in a feeding passage to a support surface. CONSTITUTION:When the pressure on a feeding passage L before an orifice S is Ps and the pressure on the support surface generating static pressure is Po, the flow rate in the orifice S becomes acoustic velocity, in the case of air, when the relation of Po/Ps<0.528 is established. By regulating Ps by a regulator V in this way, the air flow rate to be supplied to the support surface is made constant, so that load is increased, and the pressure of the support surface is sharply raised when the space is minimized, and the change of float quantity by fluctuation of the load is also minimized. Thus, the relation between the float quantity of a movable block K and the load is nearly horizontal state, and a high rigidity can be obtained.
