Title: Mobile receiver
Inventor: MURATA TAKAO
IPC: H01Q3/24
Filed: 1991-10-08
Abstract: PURPOSE:To make the mechanical following-up of an antenna unnecessary and to provide the mobile receiver made light in weight and low in cost by forming the antennas of block arrays composed of a lot of antenna elements on the respective planes of a solid surrounded by plural planes or curves. CONSTITUTION:The outputs of plural plane block arrays 1 forming circular or rectangular patch antennas are respectively inputted to a low noise converter 3. The output of the low noise converter 3 is inputted to a switch 5 and inputted to a controller 4 as well and the switch is controlled so that only the output of the block array to obtain a C/N higher than an already preset level can be inputted to an in-phase synthesizing circuit 6. With the output of the array at the highest C/N among the inputted outputs of the block arrays as a reference, the in-phase synthesizing circuit 6 synthesizes the phases of the other arrays corresponding to the phase of the reference output and afterwards outputs the synthesized phase.

Title: Tape guide made of resin
Inventor: NISHIOKA MAKOTO
IPC: G11B23/087
Filed: 1989-10-05
Abstract: PURPOSE:To obtain the tape guide which is made of a resin and has the performance equiv. to the performance of a metallic material at a low production cost by forming the tape guide of a material consisting of an ultra-high-mol. wt. polyolefin resin and a prescribed ratio of an inorg. filler by injection molding. CONSTITUTION:The tape guide is injection molded of the material consisting of 5 to 40wt.% inorg. filler per 100wt.% ultra-high-mol. wt. polyolefin resin. The ultra- high-mol. wt. polyolefin resin is a resin having the mol. wt. as large as >=800,000 and extremely low friction characteristics. The tape guide formed of only the ultra- high-mol. wt. polyolefin resin is low in surface hardness and, therefore, rugged flaws, such as dents, are liable to be generated on the surface. The inorg. filler (aluminum siliate, calcium carbonate, etc.) is consequently added at 5 to 40wt.% to the above- mentioned resin and the resin is molded. The good tape guide which has the low friction characteristics, has the high surface hardness and does not generate the flaw by striking is, therefore, obtd. The performance equal to the performance of the tape guide made of the metallic material is obtd. in this way and the material cost and working cost are lower than the costs required for making the tape guide consisting of the metallic material.

Title: Dead water back flow preventer for sprinkler circuit utilizing tap water
Inventor: SATO MITSUE
IPC: A62C35/68
Filed: 1991-10-09
Abstract: PURPOSE:To enable the use of tap water as a pressure water supply source for a sprinkler circuit. CONSTITUTION:A tap water supply pipe 1 is connected to a sprinkler circuit 4 through a check valve 2 and a water supply path 3, and an air chamber 7 is provided in the course of the water supply circuit 3. When water is supplied into the sprinkler circuit 4, air is contained in the air chamber 7 while the air is compressed by a pressure of tap water supplying the air, the supply of the water is stopped automatically as the pressure of the compressed air balances the pressure of the tap water. The pressure water of the sprinkler circuit 4 is separated and cut off the pressure water of the sprinkler circuit 4 by the compressed air and the check valve works effectively by the compressed air to prevent the back flow of dead water generated in the sprinkler circuit 4 to the side of the tap water. In addition, a pressure is always added to the water in the sprinkler circuit by the compressed air and with the opening of a valve at a sprinkler head, the pressure water can be jetted out thereby ensuring initial extinguishment of fire.

Title: Manufacture of conductive film
Inventor: KIMURA SHIZU
IPC: H01B13/00
Filed: 1988-10-18
Abstract: PURPOSE:To make the surface of a film conductive in a short time without lowering the mechanical characteristic thereof by adding silver acetate of a specific content to a polymer unit and a silver salt other than silver acetate or one or more kinds of salts of cobalt, nickel, etc., of a specific content to the silver acetate, to an aromatic polyimide acid, followed by percentage heat treatment to be formed. CONSTITUTION:Silver acetate of 0.5-3mol to 1mol of polymer unit and a silver salt other than silver acetate or one or more kinds of salts of cobalt, nickel, copper, iron, chromium and manganese of 1-20wt.% to the silver acetate are added to an aromatic polyimide acid, followed by heat treatment to be formed. The addition of the metal salts of not more than 1wt.% does not sufficiently develop the effect of precipitating silver without lowering the mechanical characteristics thereof in a short time. Conversely, the addition of the metal salts of 20wt.% or more tends to advance oxidation and to thereby lower the strength of the film. The film obtained in accordance with the invention is improved in the productivity, excellent in the mechanical characteristics, heat resistance and conductivity, thus the range of the use is made wide.

Title: Electric precipitator and air conditioner using the same
Inventor: YOSHIDA SHINJI
IPC: B03C3/45
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To prevent ozone smell and electric discharge sound from being abnormally emitted by enabling control of high voltage by a simple constitution and automatic control of secondary side current. SOLUTION: A primary side current of a high voltage unit 85 is monitored and a secondary side output of the high voltage unit 85 is controlled so as to maintain the primary side current that is being monitored at a constant value. Because the output of the high voltage unit 85 is controlled so as to maintain the primary side current at the constant value, the secondary side current is not increased. Thus, an automatic control is enabled without monitoring the secondary side current so that the constitution for high voltage control can be simplified.

Abstract: PURPOSE:To reduce noise by correcting and reducing the blower air-quantity based on an integral value of signals directly related to blower noise, thereby reducing the air-quantity in accordance with the degrees to which a rider is subjected from the blower noise. CONSTITUTION:An overall signal value calculated using the difference between a set temperature and an internal air temperature as a main function is calculated by a means 1. A command blower air-quantity is calculated as a function of the overall signal value by a means 2. Further, the number of revolutions of a blower motor 5 is controlled by a means 4 in accordance with the command blower air-quantity. In this device, signals directly correlated to blower-noise are detected by a means 6. Blower-signals are then integrated on the basis of time by a means 7. Further, the command blower air-quantity is corrected and reduced according to an integral value by a means 3. The air-quantity is thus reduced in accordance with the degree of stress to which a rider is subjected from blower-noise, and thereby noise can be reduced.
