Inventor: SATOU KOU
IPC: C23C8/32
Filed: 1980-10-30
Abstract: PURPOSE: To obtain a roller chain bush having a high strength and a high hardness and excellent in abrasion resistance, by preparing a composition containing specified rates of Cu, Cr, C, Mo, W and Fe, and providing the composition with a specified oil-contg. ratio while forming a surface-hardened layer.  
     CONSTITUTION: A composition comprising, by weight %, 1W7% Cu, 0.2W2.5% Cr, 0.5W1.2% C, 0.2W10% of one or two of Mo and W, optionally 0.05W3% of one or more of P, B and Si, and the balance being Fe and inevitable impurities, is prepared. The oil-contg. ratio of the composition is controlled at 5W35vol%, while a surface- hardened layer is formed. Thus, a sintered oil-contg. roller chain bush having the same strength as that of a conventional one, an excellent abrasion resistance and an excellent lubricativity is produced at a low cost.

Title: Perfume producing capsule
Inventor: TOMIOKA TOSHIICHI
IPC: A61L9/03
Filed: 1991-06-25
Abstract: PURPOSE:To prolong the available period of a fragrant agent by forming a fragrant-agent filling microcapsule in such a way that the core material consisting of a fragrant agent or a material containing it is covered with wall membrane materials consisting of a material whose expansion coefficient is smaller than that of the core material. CONSTITUTION:A fragrant agent part 3 is formed by making a core material of gelatin-gum arabic and impregnating a fragrant agent in its interior, and the outside thereof is exposed to air for hardening to form a skinlike part 1. On the outside of the skinlike part 1, wall membrane materials of an inorganic material 2 whose main component is titanium oxide is formed. The expansion coefficient of the inorganic material 2 is set to be smaller than that of the core material. Thus, when the surrounding temperature rises, the joining parts of the inorganic materials 2 break due to the difference in expansion between the core material and the inorganic materials 2, and the fragrant agent disperses.

Title: Constant output controller for motor
Inventor: YAMAMOTO MASARU
IPC: H02P27/06
Filed: 1989-06-15
Abstract: PURPOSE:To simplify the constitution in the constant output of a motor and to make it highly precise by letting the output of a power control amplifier be a correction signal of an output limiter and by correcting the input of a speed input system. CONSTITUTION:Let the setting signal of a power setter 7 be PM* and the output feedback signal of a motor 4 PM. If PM*>PM, then the output of a power control amplifier 10 is cut off by a diode 24. The speed is controlled on an original speed criterion. If PM*<PM, then the output of the power control amplifier 10 is in the negative. This output goes through the diode 24 and is inputted into an output limiter 11 as a correction signal. The output limiter 11 reduces the output of an acceleration-deceleration controller 12 in accordance with the input of the correction signal and reduces the speed of the motor 4. As a result, the output PM of the motor 4 is reduced and the motor is automatically controlled, for which PM*=PM.

IPC: F28D20/00
Filed: 1983-08-24
Abstract: PURPOSE:To contrive the acceleration of convection in a liquid phase, and to obtain the heat accumulating capsule having excellent heat energy absorbing performance by a method wherein the vertical relative position between a liquid phase and a solid phase is changed inversely, in a heat energy absorbing process. CONSTITUTION:A plate 4b processed by a shape memory alloy treatment is made to memorize the shape of a downward side recess curved surface at the B point temperature, and made to change to the shape of a downward side convex curved surface at the A point temperature, then sealed in a capsule 2. At the heating of a heat accumulating capsule 3 from outer periphery thereof, the temperature of a heat accumulating material is started from A point and moved to B point. In this case, a liquid phase 1a and a solid phase 1b coexist vertically in the capsule. When the temperature of a spring 4 is raised up to the B point, the shape of shape memory alloy 4b changes to upward convex curved surface, the memory alloy lifts the solid phase 1b. Therefore, the location of the liquid phase 1a and the solid phase 1b is reversed, the liquid heated on the cylindrical bottom part is lifted up, the liquid is taken away the heat energy thereof at the solid phase bottom part, then cooled and falls to the cylindrical bottom part. The convection in the liquid phase part is generated by said heating cycle, the solid phase 1b is melted perfectly, accordingly, the liquid temperature is raised up to the D point.

Title: Recorder and reproducer of digital data
Inventor: MISAWA EIJI
IPC: G11B20/10
Filed: 1981-09-28
Abstract: PURPOSE:To ensure the accurate recording and reproduction of a digital data by means of a general-purpose tape recorder, by adding a data signal and an auxiliary signal together with the weighting of a prescribed ratio. CONSTITUTION:The data signal Pa and auxiliary signal Pb are delivered through output terminals 6a and 6b of an output port 6. The signal Pb has the same logic as the signal Pa when the original data read out of an RAM4 has the logic H and vice versa when the original data has the logic L. Then both signals Pa and Pb are weighted with a prescribed ratio and supplied to an adding means 9 to be converted into the signal Pc. For this added value, the amplitude has a prescribed ratio when the data has the logics L and H respectively. Therefore the coincidence is obtained between the positive and negative areas within a period of the signal Pc for every period. Thus a normal waveform is obtained although the signal Pc is supplied to an output terminal 14 through a DC blocking capacitor 13.

Filed: 1984-07-25
Abstract: PURPOSE:To perform optical reproducing without requiring any tracking servo by recording information signals so that the width of a recording track is sufficiently larger than the diameter of a light spot used for reproduction. CONSTITUTION:Information signals are recorded on a photomagnetic disk 1 with a wide recording track width Tw as shown in the figure by a magnetic head, and the diameter of a light spot 11 which scans a recording track at the reproducing time is made sufficiently smaller than the track width Tw. Since the track width Tw is sufficiently larger than the diameter of the light spot 11, the light spot 11 is not deviated from the recording track 10 even if face deflection occurs in the disc 1. Thus, optical reproduction is performed without requiring any tracking servo.
