Abstract: PROBLEM TO BE SOLVED: To improve a yield of a thermal processing for raised productivity by forming a dummy wafer for semiconductor thermal process of a glass carbon base material comprising young's modulus of specific range. SOLUTION: As a glass-like carbon, an organic sulfonic acid is added to a thermo-setting resin, which is cold-polymerized to provide a fluid polymer and injected in a mold in fluid state, and then temperature is gently raised for setting to form a molded body. The molded body is raised, in temperature, to 800-1200 deg.C at a specified speed for baking/carbonization, and its surface is worked, then further heated to 2000-2500 deg.C for purifying process. The glass- like carbon base material obtained by this method has thermal-impact resistance temperature of 700 deg.C or above while Young's modulus being 2530 GPa, applicable for preventing crack or breakage of the base material. The glass-like carbon base material has no grain boundary, and the one with maximum pore size 0.1 μm or with rate of perforation 0.01% or less can be manufactured. Divergence of carbon fine particles, etc., is not feared.

Title: Heat collector
Inventor: YAMAGUCHI KOICHIRO
IPC: F24S10/30
Filed: 1985-09-05
Abstract: PURPOSE:To increase sunshine heat collecting temperature as well as heat collecting efficiency and obtain the heat collector of small size and light weight by a method wherein air entering through an air inflow port is made to flow through a gap between a heat collecting panel and a transparent body to rise the temperature thereof and collect heat by introducing it into a refrigerant evaporator while cool airflow after collecting the heat is lowered to the side of a heat insulating material provided behind the heat collecting panel. CONSTITUTION:Sunshine absorbed by a refrigerant evaporator 1 heats and evaporates refrigerant flowing through the refrigerant evaporator 1. On the other hand, the sunshine absorbed by a heat-collecting panel 2 makes a kind of hothouse between a transparent body 4 and a heat collecting panel 2, raises the temperature of air to generate high temperature airflow and flows into the uppermost refrigerant evaporator 1, which suck air from an inflow air port 5 and heats it to evaporate the refrigerant; thus, the heat thereof is collected. The refrigerant of comparatively low pressure constituting a heat pump flows through a refrigerant evaporator 1 and the refrigerant is evaporated in accordance with the pressure thereof to collect heat by exchanging heat with the heat of the high-temperature airflo while the airflow, which passed through the refrigerant evaporator 1, becomes cool air and descends behind the insulating material 3. Natural convection is promoted by the high-temperature airflow at the surface side of the heat-collecting panel and the flow down of cool air at the behind side to enhance inducting effect of air from the inflow air port 5.

Title: Pillow
Inventor: SEO HARUO
IPC: A47G9/10
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To prevent hands from becoming asleep in spite of sleeping with the hands crossed under one's head and to make air-permeable enough to prevent heat from being kept inside by forming a first recessed part for arranging a head part and a second recessed part for inserting arms at the upper/lower part of the center of a front/rear direction in the state of extending to right/left directions by facing inward in vertical direction. SOLUTION: A pillow 1 is used by fitting a swelling part 56 to a neck and arranging the head in a recess 53 (first recessed part) between swelling parts 55 and 56. As a mesh-state reinforcing material buried in a cushion material generates proper elasticity, a user feels comfortable and is prevented from being in an unnatural posture to avoid giving a burden to a neck, shoulders and a back. Then, the hands crossed behind the head can be housed in the recess (second recessed part) 54 formed between the parts 55 and 56 at the lower part of the pillow 1. As the arms are never inserted between the pillow 1 and a floor consequently, the hands are not pressurized and never asleep. In addition as the hands are arranged in the second recessed part 54 at the lower part of the pillow 1, air-permeability is improved and heat is never kept inside.

Title: Ink medium
Inventor: FUKUSHIMA HITOSHI
IPC: B41J31/00
Filed: 1986-08-22
Abstract: PURPOSE:To enable high-quality characters or images to be printed even on a transfer recording paper having an extremely poor surface smoothness, by incorporating a particulate polymer having a sphere diameter in a specified range into a thermoplastic magnetic ink layer comprising particulates of a ferromagnetic material. CONSTITUTION:If the sphere diameter of a particulate polymer incorporated in an ink layer is less than 0.01mum, the interaction between particulates of a ferromagnetic material and the particulate polymer is weakened, and transfer efficiency is considerably deteriorated. If the sphere diameter is more than 10mum, the interaction becomes excessively strong, leading to a stronger cohesive force and a higher melt viscosity. Therefore, the particulate polymer having a sphere diameter in the range of 0.01-10mum is incorporated in the ink layer in an amount of 2-30pts.wt. By this, favorable transfer can be ensured, and a printed matter can be obtained with favorable transfer efficiency. In addition, it is made possible to print characters or images with extremely high quality even on a transfer recording paper having an extremely poor surface smoothness or a film not so high in affinity for inks.

Title: Mos semiconductor device
Inventor: KINOSHITA HIROYUKI
IPC: H01L29/788
Filed: 1982-11-11
Abstract: PURPOSE:To enhance sharply the electrostatic breakdown voltage of an MOS semiconductor device by a method wherein the distances between the diffusion layers of an inside circuit and a diffusion layer constructing a gate protective circuit are set properly. CONSTITUTION:The distances between the diffusion layer 14 of a gate protective circuit and the respective diffusion layers 15 of an inside circuit are separated by the value or more not to be implanted with minority carriers from the diffusion layers 15 of the inside circuit to the depletion layer of the diffusion layer 14 of the gate protective circuit to be generated according to application of a surge voltage, and are made larger than the minimum distance between the diffusion layers 15 of the inside circuit. Only by placing a diffusion layer close by another diffusion layer to be applied with a surge voltage, the electrostatic breakdown voltage is reduced sharply than the original value, and the diffusion layer biased reversely is broken. Accordingly, by setting large the distances between the diffusion layer 14 of the gate protective circuit and the diffusion layers 15 constructing the inside circuit, the diffusion layers 15 of the inside circuit become hard to receive the influence of a substrate potential rise in the neighborhood of the diffusion layer 14 of the gate protective circuit to be generated by application of the surge voltage, and moreover even if minority carriers are generated from the inside diffusion layers 15, because the greater part of the minority carriers are rebonded in a silicon substrate, the electrostatic breakdown voltage can be enhanced remarkably.
