Title: Light scattering tape or sheet
Inventor: TSUBOTA KENJI
IPC: G02B5/02
Filed: 1979-03-09
Abstract: PURPOSE: To enhance the productivity of the title tape or sheet and the light scattering effect thereof by uniformly applying adhesive fine particles to at least one side of a light transmissive substrate at a state where the particles are bonded to each other and unified.  
     CONSTITUTION: 5W150g/m 2  of acrylic adhesive fine particles 2 with a middle diameter of 5W100μ are applied about uniformly to one side or both sides of light transmissive substrate 1 such as polyester film at a state where the particles are bonded to each other and unified without isolation separation or they are bonded and unified with other adhesive or non-adhesive layer in-between, forming a rough surface of corrugated structure. When the particles are isolation-separated from each other, a flat portion tends to form between the particles, and this portion does not scatter light to pass it straight. Thus, a light scattering tape or sheet with high light scattering effect is obtained with high productivity.

IPC: G01B21/32
Filed: 1986-02-12
Abstract: PURPOSE:To quantitatively measure and display the degree of deformation from an reference shape, by determining a conversion coefficient to quantify the similarity between the reference shape and a deformed shape. CONSTITUTION:It is assumed that a graphic serving as reference for a proper shape connecting a number of feature points P1, P2, P3... by a straight line or curved line exists and the origin of an x-y coordinate system is at the gravity center G of the graphic. Also, it is assumed that a deformed graphic to be compared to the reference graphic exists and likewise, the origin of an x'-y' coordinate system is at the gravity center G of the graphic. The deformed graphic has feature points P'1, P'2, P'3... corresponding to feature points. Then, when coordinates of respective feature points of the reference graphic and the deformed graphic are expressed by the x-y coordinate system and the x'-y' system respectively and moreover and a coordination conversion is done about the respective feature points from the x-y coordinate system to the x'-y' coordinate system by a formula, a conversion coefficient (alpha, beta) can be determined. Based on the coefficient (alpha, beta) thus obtained, the degree of deformation of the deformed graphic is measured and displayed from the reference shape.

Title: Manufacture of molding with thermosetting liquid resin
Inventor: HIRAI HISASHI
IPC: B29C33/14
Filed: 1991-02-22
Abstract: PURPOSE:To prevent the generation of a boundary surface between a resin injected after a holding means is removed and a previously injected resin by holding a substance to be casted by a casting substance holding means and cooling the whole holding means by a cooling means when the inside of a mold is supplied with the thermo-setting liquid resin. CONSTITUTION:A mold is heated at a fixed temperature on manufacture. A plurality of pins 13 as casted substance holding means supporting a coil body 12 are cooled by flowing a refrigerant into the refrigerant flow paths 17 of the pins 13. The inside of the mold is decompressed, and the inside of a cavity 11 is supplied with a cast resin from a plurality of cast-resin supply ports. Consequently, the resin is cured by the heat of the hot mold, but the curing of the cast resin in the peripheral section of the pin 13 is made slower than other resins because the pins 13 are cooled. The contact end section of the pin 13 is moved up to the surface of a mold insidewall 14 from the position of the surface of the coil body 12, and the cast resin from a resin injection pipe 16 is injected to a section, where the pin 13 is installed, and cured together with the resin of the section, in which curing is made to slow.

Title: Planetary reduction gears with reverse input cutoff mechanism
Inventor: SAITO TAKAHIDE
IPC: F16H35/00
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To reduce a size and cost by providing a clutch mechanism, which generates a relative rotation to an output shaft by flux of an exciting coil canceling flux of a permanent magnet, between a stationary member and the output shaft. SOLUTION: In this planetary reduction gears with reverse input cutoff mechanism, when a power is transmitted from a drive part side, an armature 24 integrally fixed to an output shaft 14 by flux of an exciting coil 23 is released from a friction plate 22, and when power is transmitted from a driven part side, the armature 24 is absorbed to the friction plate 22 by flux of a permanent magnet 21. Therefore, an output rotation from a speed reduction part 10 is transmitted to the output shaft 14. On the other hand, a reverse input rotation from the output shaft 14 is not transmitted to an input shaft 12. In other words, though driving transmission from the driving part side can be carried out, the driving transmission from the driven part side can not be carried out.  A mechanism for switching transmission/cut off of rotation power is more simple than conventional mechanism, reduction in size in a radial direction can be enhanced, cost can be reduced, and it is preferable for a severe case which has limit in size.

Title: Control method for mixing servo valve
Inventor: EGAMI TOYOHIKO
IPC: F24H1/10
Filed: 1987-02-10
Abstract: PURPOSE:To improve hot water feed characteristics during the re-feed of hot water and to rapidly stabilize feed hot water temperature, by a method wherein the motion of a mixing servo valve is kept stopped until, during re-feed of hot water, a feed hot water temperature is increased to a set value. CONSTITUTION:When, during the re-feed of hot water, there is no change in a set temperature in the case of hot start, the motion to the feed water closing side of a mixing servo valve 3 is kept stopped until a feed hot water temperature is increased to a set temperature. This constitution enables reduction of overshoot occasioned by a motion to the feed water closing side at the initial stage, permits improvement of hot water feed characteristics, and allows stabilization of a feed hot water temperature to a set value in a relatively short time.

Title: Circuit breaker employing semiconductor device
Inventor: NARITA HIROSHI
IPC: H02H3/08
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To ensure high speed high frequency interruption by providing a low rated voltage, a small loss self-extinguishing semiconductor device in series with a mechanical interrupter. SOLUTION: A power transistor TR.SW (self-extinguishing semiconductor element) is provided in series with a vacuum interrupter VCB. The power transistor TR.SW has a rated voltage lower than that of a semiconductor element interrupter GTO.SW. The loss in a semiconductor element generally decreases as the rated voltage decreases and a single power transistor is known as a small loss semiconductor element. Since the self-extinguishing semiconductor element TR.SW commutates overcurrent to the semiconductor element interrupter GTO.SW, contact of the mechanical interrupter VCB is protected against damage and since a low rated voltage semiconductor element can be employed in the self-extinguishing semiconductor element TR.SW, the loss can be reduced at the time of conduction. Furthermore, high speed high frequency interruption can be ensured because the mechanical interrupter VCB performs no current interruption.
