Title: Picture amplitude stabilizing device
Inventor: NAKAJIMA TOSHIYUKI
IPC: H04N3/185
Filed: 1987-04-14
Abstract: PURPOSE:To make a picture amplitude of a CRT display device stable by detecting the fluctuation of an input voltage of a picture amplitude stabilizing device and feeding it directly back to an error detection section of a power voltage stabilizing circuit for a horizontal output circuit. CONSTITUTION:A voltage fluctuation feedback resistor 12 of an input power voltage is provided between a power voltage input terminal of a picture amplitude stabilizing device and an error detection section of a power voltage stabilizing circuit. If an input voltage V1 of the picture amplitude stabilizing device is decreased due to any cause, the fluctuation of the input voltage V1 detected by the voltage fluctuation feedback resistor 12 is fed back to an error detection section of the stabilizing circuit. Thus, an error amplification transistor (TR) 7 is turned off and a control TR 6 is turned on. Then the output voltage is controlled to be an initial value and the amplitude of picture is stabilized.

Title: Decorative board
Inventor: ONODERA KAZUO
IPC: B30B9/00
Filed: 1978-07-27
Abstract: PURPOSE: To obtain a board having a fiber-like hand and waterproofness and capable of adhering strongly, by heating the sheet surface having synthetic resin mixed between fibers, impregnating synthetic resin between fibers, and forming rugged surface for adhesion on the surface thereof.  
     CONSTITUTION: Powder or granular synthetic resin is mixed in pulp material or used paper, and is made into a paper sheet. This is led into heat roll (100 to  300°C), and the synthetic resin mixed in scatrered points is heated above the softening point and is permeated into fibers. At this time, by adjusting the roll temperature and feed speed, this permeation is limited to take place only on the paper sheet surface, causing no changes in the synthetic resin inside. This paper sheet is cooled and the synthetic resin is solidified, then the part of the surface to be adhered is rubbed against with a wire brush or by embossing. the fiber layer in which internal synthetic resin is not permeated is exposed in certain positions on the surface layer in which synthetic resin is permeated.

Title: Method and apparatus for resin sealing of semiconductor device
Inventor: TANAKA SUEKICHI
IPC: H01L21/56
Filed: 1989-04-10
Abstract: PURPOSE:To surely prevent mismatch of the cavities of upper and lower molds by supporting a surface plate with support pins separatedly from spacer blocks and matching the upper mold to the lower mold which is supported horizontally and vertically movably with fixation members joined to the spacer blocks. CONSTITUTION:Support pins 20 to elastically support a surface plate 1 are fastened by screwing with bolts 21 from a base 3. A pair of spacer blocks 22 having fitting grooves 22a are fixed on the base 3 with a specific interval alphafrom the surface plate 1. Therefore, even if the pins 20 are elastically deformed by compression in clamping, a slight interval is kept between the spacer blocks 22 and the surface plate 1. Thereby, when the thermal deformations of upper and lower parts differ or a press is deformed by heat or clattered, smooth fitting is possible without applying unnatural force to guide pins 19 and guide pushes, surely preventing mismatch of the cavities of the upper and lower molds.

Title: Roller chain
Inventor: SHOJI HIROAKI
IPC: B65G17/24
Filed: 1988-04-13
Abstract: PURPOSE:To enable a noise to be substantially reduced in a chain, when it meshes with a sprocket, without increasing a supply amount of oil or the like by providing a hole in a bush, arranged between a pin and a roller, and a cushion unit, having elasticity in thickness larger than the thickness of the bush, in the hole. CONSTITUTION:When a sprocket 1 is in rotation, a roller 7, to a position B just before it meshes with the sprocket 1, is pressed to the bottom from inside to be held by a cushion unit 10, and the roller 7, not freely moving vertically and laterally by a running vibration or the like, generates no hammering noise colliding against a bush 4A and/or right and left inner link plates 3. Next the roller 7, when it moves to a position D meshing with the sprocket 1, performs soft landing on a cushion unit 9 in a tooth bottom surface part of the sprocket 1, and by bottom direction resultant force (f) of a component of tension F of a chain and its own weight, the roller reaches a tooth bottom surface of the sprocket 1 while pressing the cushion unit 9 so as to crush it. Simultaneously the roller is placed in a condition that it is pressed to be held with the bush 4A between the tooth bottom surface and a pin 5. Here the cushion unit 10 in a bush hole 4a, while even being crushed, moderates an impact against the bush 4A, suppressing generation of hammering noise.

Title: Graphite mold for plastic molding
Inventor: TAKAGI TAKASHI
IPC: B29C45/26
Filed: 1989-04-11
Abstract: PURPOSE:To contrive improvements in processability and mold release properties of a product, by a method wherein fluorine resin is applied over at least an exposed part of a graphite material within a molding cavity at a thickness falling within a range of 10-2000mum. CONSTITUTION:Fluorine resin is applied over at least an exposed part of a graphite material within a molding cavity at a thickness falling within a range of 10-2000mum. In addition, in the case where a thickness of a coating film to be formed is thicker than this, it is possible that thermal conductivity becomes worse on the contray by generating a crack in the coating film or peeling off the coating film from the surface of the graphite. Then in the case where the thickness is thinner than 10mum, it becomes impossible to perform favorably mold release of a plastic product by exposing the surface of the graphite material. With this construction, cooling of the plastic material after molding with a mold is performed efficiently and an improvement in efficiency of the molding with the mold is contrived.

Title: Cutter for stone material
Inventor: TSURU AKIHIKO
IPC: B28D7/02
Filed: 1995-03-24
Abstract: PURPOSE: To prevent the scattering of dust by demarcating a cut powder housing chamber on one side of a machine frame and opening the cut powder housing chamber on the downstream side of the lower part of a rotary blade and forming the exhaust hole released to the outside to a part of the wall demarcating the cut powder housing chamber. CONSTITUTION: Since a cut powder housing chamber 50 develops the same action as a duct, air streams going from the front end of a rotary blade 10 toward the cut powder housing chamber 50 are generated in the periphery of the blade 10 accompanied by the rotation of the blade 10. Therefore, the effect of centrifugal force becomes hard to act and whire-up fine cut powder (dust) is carried by the air streams to be sucked into the housing chamber 50. The air streams flow out to the outside from the cut powder housing chamber 50 through an exhaust hole. At this time, a part of the dust is together discharged but, if the position of the exhaust hole is appropriately selected to guide the dust to the outside of a work area, work environment can be improved.
