Title: Black color metal for decoration
Inventor: SUZUKI HIDEAKI
IPC: A44C27/00
Filed: 1981-04-17
Abstract: PURPOSE:To produce decorative black color metal having gloss from any metallic materials by compressing ultrafine powder of metals and their alloy under heating and finishing the surfaces thereof. CONSTITUTION:When gaseous Ar of about 100Torr is sealed into a vacuum deposition device, and Cu is heated to evaporate by using filaments of W, Cu atoms evaporate and at this same instant, they collide against the residual gaseous molecules of low temp., grow to bigger sizes and stick to the inside wall of the device, thereby forming fine powder. The average grain sizes of this fine powder is within a 0.1-0.01mu range. Next, this fine powder is recovered, and is molded under pressurizing at about 350 deg.C by using a vacuum hot press, then, the molding is machined, ground and finished to accuracy of about 0.5-1mu surface roughness, whereby it is made into the product of a black color tone. Metals and alloys having the characteristics required depending upon use objects are selected for the ultrafine powder. It is equally well to use plasma jet flames as a method of producing the ultrafine powder.

Title: Rolling method of crown tooth on work such as gear
Inventor: FUJIWARA HIDEYUKI
IPC: B21H5/00
Filed: 1982-04-06
Abstract: PURPOSE:To roll crown teeth on a work such as a gear, etc. by slanting each tooth arranging face of a pair of flat dies slightly to the rotation axis of the work and parallel to each other, and shifting a pair of flat dies. CONSTITUTION:Tooth arranging faces 3e, 3f of a pair of flat dies 3a, 3b are made parallel to each other, and mounted to a rolling device slightly slanting to the rotation axis 0 of a work 4.

Flat dies 3a, 3b are moved in the direction perpendicular to the rotation axis 0 of the work 4 to opposite dead center of reciprocation and crown teeth 4a are created on the peripheral face of the work 4. Consequently, a tooth 3a' of a flat die 3a and a tooth 3b' of another flat die 3b are formed by curved surfaces 4b, 4c that slant toward the different direction looked on the axial section of the work 4 to the tooth surface of a tooth 4a created on the work 4 and tapered to different direction looking the tooth 4a of the work 4 on a plane.

Title: Mobile radio communication system
Inventor: IWAMA YOSHIYUKI
IPC: H04B1/50
Filed: 1978-05-17
Abstract: PURPOSE: To eliminate the need for filtering off a reception spurious-frequency component, by apparently regarding disturbance noises as a side tone by setting a transmission frequency to the corresponding spurious frequency of the reception part.  
     CONSTITUTION: As one of factors of spurious generation, a mobile radio equipment on a duplex system bears a relation of intermediate frequency f if =nf s ∼mf t  [(f s ) is a reception spurious frequency, (f t ) is a transmission frequency, and (n) and (m) are integers]. Especially, when a relation of f s =f t +f if /2 is within the reception frequency band, a beat between reception spurious (f s ) and transmission frequency (f t ) drops into the intermediate frequency band of reception part 15 so as to prevent the malfunction. For the purpose, difference (f▵) with the transmission frequency is set to half intermediate frequency (f if ). As a result, reception spurious (f s3 ) agrees with reception frequency (f r 2) and there is no need to suppress the reception spurious frequency f s =f t +f if /2 by filter 18.

Title: Time switch control system
Inventor: FUJIWARA TATSUO
IPC: H04Q11/04
Filed: 1987-03-13
Abstract: PURPOSE:To decrease replaced information by constituting a data memory based on cells divided into two, master and slave calls as the unit. CONSTITUTION:The distinction of master and slave and the number of a storage cell used for the readout of a data memory 1 are stored in an address control memory 2 as time slot replacement information. The most significant bit of the read/write address of the memory 1 is used to change over the master/slave cell and the low-order bits except the most significant bit are used to designate the cell number. The most significant bit of the address is inverted by the read/write to change over the master/slave cell and the low-order bits except the most significant bit are identical for the read/write to be used to designate the cell number. Thus, the replacement control information is less and the management is facilitated.

SOLUTION: A hot water supply system comprises a hot water supply circuit A, a bath tub 10 to receive supply of hot water from a hot water supply circuit A, a bath circulation circuit C to circulate hot water in the bath tub 10, a water level measuring means to compute a water level in the bath tub based on an output signal from a pressure sensor 5 arranged in a bath circulation circuit C, and a heating circuit B for heating hot water. The measurement range of a pressure from a pressure sensor 5 is constituted such that a water level measurement range and a measurement range for inspecting water leakage are switched to each other. During inspection of water leakage, the bath circulation circuit C and the heating circuit B are brought into a short-circuit state and form a closed circuit not released to the atmosphere, and the internal part of the closed circuit is pressurized.  Under this state and from the detecting result of the pressure sensor 5, the presence of water leakage of the closed circuit is decided by whether lowering of a pressure to a given value is detected.
