IPC: G11B5/09
Filed: 1982-07-16
Abstract: PURPOSE:To make the vertical magnetization recording due to high-linearity pulse width modulation possible with a simple structure, by using the carrier where the ratio of an effective recording width (g) to a wavelength lambdac is an integer approximately. CONSTITUTION:The input signal amplified by an amplifier 1 in the recording system using a magnetic tape as a vertical magnetization medium 10 is sent to a modulator 2 and is subjected to the pulse width modulation by the carrier generated by a carrier generator 3 and is sent to a recording and reproducing head 11 through a recording amplifier 4. The wavelength lambdac of the carrier generated by the carrier generator 3 is so set that the ratio g/lambdac of the effective recording width (g) to the wavelength lambdac is an integer approximately, and the reproducing sensitivity is set to 0 for a wavelength obtained by dividing the effective recording width (g) by the integer. Thus, since the carrier having the wavelength lambdac(=g/integer) is not reproduced but only the input signal is reproduced, no demodulators are necessary for reproduction, and signals are recorded and reproduced easily with a high fidelity.

Title: Animal or vegetable lubricating oil
Inventor: IBUKI MASAHISA
IPC: C10N30/02
Filed: 1995-05-22
Abstract: PURPOSE: To obtain an animal or vegetable lubricating oil having a low melting point, a high viscosity and a good stability by using an animal or vegetable oil which has a specified iodine value and in which the content of isolated trans isomers in a triglyceride constituting a fatty acid is in a specified range. CONSTITUTION: This oil has a content of isolated trans isomers in a triglyceride constituting a fatty acid of 40wt.% and an iodine value of 50-90. Although this oil can be produced by using an animal or vegetable fat or oil as the starting material, a vegetable oil is desirable in respect of its odorlessness. The isolated trans isomer refers to a nonconjugated trans unsaturated fatty acid and desirably includes compounds prepared by isomerizing palmitoleic acid, oleic acid, vaccenic acid or linolic acid into the corresponding trans isomers. In this isomerization, the animal or vegetable oil is hardened by isomerization in the presence of a nickel catalyst (especially desirably a poisoned waste catalyst), and the low-melting fraction is separated to form a lubricating oil.  This oil can contribute to the environmental protection when used in a chain saw or is suitably used in a food processing machine.

Title: Heat pipe type heat exchanger
Inventor: MIKI HIDEKI
IPC: F24F7/08
Filed: 1990-05-15
Abstract: PURPOSE:To prevent fluid from being mixed between ducts, i.e., a cause of cross contamination being produced, by forming a partition wall for dividing the duct into an air supply duct and an exhaust duct into a hollow double wall structure, and pressurizing the interior of the hollow structure. CONSTITUTION:The interior of a container 1 constituting a heat exchanger body is divided by a double wall structure partition wall 3 at the middle of which it is formed into a hollow structure to construct an air supply and an exhaust duct 4. Once a fan 5 is actuated, air is sent into the hollow structure of the partition wall 3 through a pressurizing fan duct 6, and hence the interior of the hollow structure is pressurized. For an air flow around the partition wall, pressure in the partition wall hollow structure is kept at a pressure higher than the inside of air supply and exhaust ducts. Pressurized air in the partition wall flows so as to be forced out into both ducts after passing through a gap between a heat pipe 2 and the partition wall 3 to prevent mixing between an air supply part 7a and an exhaust part 7b.

Title: Electromagnetic cooker
Inventor: HOSOITO TSUYOSHI
IPC: H05B6/12
Filed: 1992-05-15
Abstract: PURPOSE:To properly control temperature, by detecting an initial temperature change degree. CONSTITUTION:Since a pan 15 is contacted to a top plate 11, detected temperature from a temperature sensor 13 in the middle of a heating coil 14 is higher than the temperature of oil 15a. When the detected temperature reaches 100 deg.C, a temperature change degree (temperature rising degree) per minute is calculated, and based on the degree, an initial control time is set. That is in the set time, the coil 14 is drive-controlled at the initial control temperature by the change degree. Then after the initial control time elapses, the coil 14 is drive-controlled at a basic control temperature. That is when the detected temperature exceeds the basic control temperature, the drive of the coil 14 is stopped, and when it is not higher than that temperature, the drive of the coil 14 is restarted, repeating this procedure until cooking is stopped. This can quicken the temperature rising of substance to-be-heated, and proper temperature control can be made without overshooting the temperature of the substance to-be-heated even when heating load is small.

Title: Rolling diaphragm
Inventor: OOSAWA HIROYUKI
IPC: F15B15/10
Filed: 1979-09-26
Abstract: PURPOSE: To improve the durability and the reliability of a rolling diaphragm, by forming the rolling diaphragm of bowler hat shape used for a pressure response equipment like ignition timing controller in an internal combustion engine in such a manner as to eliminate the generation of wrinkles in its rolling part or the close contact mutually between its circumferential wall portions.  
     CONSTITUTION: If a rolling diaphragm 1a is equipped between a piston 6a and cylinder 10a of a pressure response equipment like suction pressure operating ignition timing controllers for an internal combustion engine, wrinkles are not produced in a rolling part 12a while circumferential wall portions stretched to both ends of the rolling part are not closely contacted to each other. This is because a gradual increase of diameter of a circumferential wall 8a from its top wall 5a to a folding start end (a) of the rolling part prevents the generation of wrinkles while because a rapid increase of diameter of the circumferential wall 8a from the folding start end (a) of the rolling part weakens the shrinking force of diameter in the circumferential portion situated in the side of an inner circumferential face 11a of the cylinder to prevent the circumferential wall portions from being closely contacted to each other.
