Filed: 1990-11-14
Abstract: PURPOSE:To provide a defreezing chamber having less irregular distribution of defreezing and capable of performing a defreezing within a short period of time by a method wherein during a defreezing operation, a damper thermostat is forcedly released and a blower is forcedly operated and at the same time both radiation heater and heating heater are electrically energized in a period ranging from a starting of defreezing to an increased predetermined temperature and subsequently the electrical energization of the heating heater is stopped and the electrical energization for the radiation heater is intermittently carried out in a predetermined manner. CONSTITUTION:A timer 49 in the second stage starts to count time. At this time, a setting time (t2) is automatically set to a time (t2) in which constants predetermined in response to a selected thickness and a finished state are multiplied to the time (t1) in the first stage. The radiation heater 29 is intermittently electrically energized in response to a timer 51 in concurrent with the time counter and the heating heater 31 at the bottom surface is terminated in its electrical energization. At this time, a blower 17 and a damper thermostat 18 are subsequently forcedly operated or forcedly released and then the cold air is continuously fed. At the second stage, since a heating with a more restricted heating calorie than that of the first stage is carried out intermittently and from upward surface, a heat giving or heat receiving operation from the surface of the defreezed food to its center is promoted and then the defreezing is promoted while the surface temperature is being prevented from being increased with the old air.

Title: Manufacture of multilayer printed wiring board
Inventor: KAZAMA SHINICHI
IPC: B26F1/16
Filed: 1993-11-16
Abstract: PURPOSE:To control haloing without degradation in working efficiency for higher stability and reliability, by placing a porous plate of a specified thickness between boards before drilling. CONSTITUTION:A multilayer printed board 1 includes at least an inner circuit board 2, a prepreg layer 4 and outer conductive layers 5. The printed board 1 is drilled to form through holes 6 for connection between layers, and circuit patterns are formed on the outer layers. In the above drilling operation, a plurality of the boards are stacked with a porous plate 10, 50-500mum thick, having hollow portions 11, in between. As a result, powder produced during drilling operation is housed in the hollow portions 11 in the porous plates 10. This eliminates fine cracks that are likely to be caused by waste powder discharged between the inner layer surfaces and the board materials, and thus controls haloing. In addition this method enables drilling a plurality of boards at a time, and thus will not degrade working efficiency.

Filed: 1989-12-01
Abstract: PURPOSE:To control the temperature distribution on a poly-Si surface so as to form an excellent single crystal by a method wherein SiO2 and Si3N4 are laminated on the poly-Si and when respective refractive indexes n1, n2 and laser beam length lambda are specified, the thickness of SiO2 layer and Si3N4 layer are respectively selected to be lambda/4n1, lambda/4n2 to increase the reflecting powers. CONSTITUTION:An SiO2 2, an Si3N4 3, a poly-Si layer 3 are laminated by CVD process on an Si substrate 1. Next, a reflection preventive film 6 comprising another SiO2 layer 4, another Si3N4 layer 5 in the same thickness is formed on the poly-Si layer 3. Next, a window is made in the film 6.

Abstract: PURPOSE:To improve flexible usability and extendability of a complicated paper sheet processor by eliminating complication of wiring between control parts and various sensors in a paper sheet processor and steep rising in a const. CONSTITUTION:A device total unit is divided into a plurality of mechanism sections 10a, 10b,...50, to perform control respectively by independent control means 101 to 107. Accordingly, an electric wire group, for connecting between the control means and sensors, actuators provided in the mechanism sections, can be sufficiently shortened.

Title: Loaded weight-measuring instrument
Inventor: OBARA MICHIYA
IPC: B60P5/00
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To simply calculate a loaded weight by constituting a loaded weight- measuring instrument interposed between a load-carrying platform of a vehicle and a wheel, of a base body mounted to one of the platform and the wheel and a moving element graduated in a longitudinal direction which is set to the other of the base body and the wheel and is slidably fitted to the base body. SOLUTION: An upper end of a base body 18 is mounted at a bottom face of a load-carrying platform, and a lower end of a moving element 20 is kept in touch with a wheel 16. The load-carrying platform is lowered as a weight on the load-carrying platform increases, and therefore a fit distance of the base body 18 and moving element 20 is shortened. Since the lowered amount corresponds to the weight loaded on the platform, a scale 22 at the time is read and converted to a loaded weight. Suitable numeric values or numeric values converted to weights, etc., are preferably indicated on the scale 22. A weight loaded on the load-carrying platform of the vehicle can thus be measured readily and quickly in a simple constitution of the base body 18 and moving element 20. Overloading is prevented more effectively than when the loaded weight-measuring instrument is used at the loading time.

Title: Making of ski by injection molding and structure of ski molded thereby
Inventor: JIYANNMARII KAZAIYON
IPC: A63C5/12
Filed: 1990-11-19
Abstract: PURPOSE: To provide peripheral members including a plate-shaped lower member, a wall-shaped upper member, and an upper mechanical reinforcement member, and position and connect all the members to each other by injecting composing components of hardening foam to an inner space parted by the peripheral members of a ski to be swollen and hardened. CONSTITUTION: Composing components of hardening foam such as polyurethane foam or phenol foam are injected into a film of a tubular partition 14 to fill space between peripheral members of a ski plate. During expansion of the foam, foaming material pushes the tubular film to deform it to push reinforcement member base material 15 up to be applied to an inner surface of an upper member 6. The tubular film composes an interface between the upper member 6 and the foam 16 for securing attachment between members of material 12, 15 to which preimpregnation treatment is applied and the foam 16. Hardening reaction of foam generally generates heat, and this heat assists attachment between the base material 15 and the upper member 6.
