Title: Reactor provided with function of current detection
Inventor: OOBA KATSUMI
IPC: H01F38/28
Filed: 1984-07-02
Abstract: PURPOSE:To measure a current value of a main winding for reactor easily by arranging a winding for current detection on an iron core on which a main winding for reactor is wound and using a voltage value generated in said current detection winding and that generated in said main winding. CONSTITUTION:A winding Wi for current detection is arranged on the same iron core. The value of mutual inductance between the winding Wi and a main winding W for reactor is so formed that it is same as the value Li of a self inductance of the winding W. Consequently, a voltage VM (t) generated between the wind-finishing ends B and C of two windings W and Wi shows the value which is in proportion to a load current i(t) flowing in the winding W. Accordingly, a value of the current i(t) can be worked out by dividing that value by a d.c. resistance of the winding W.

Title: High withstand voltage semiconductor device
Inventor: TAKAHASHI YOSHITOMO
IPC: H01L29/72
Filed: 1985-06-21
Abstract: PURPOSE:To make it possible to implement high withstand voltage, by partially providing an embedded layer, which has the second conducting type and has concentration higher than that of a collector substrate, on a first conducting type semiconductor substrate, which is to becomes a collector, so that the embedded layer is separated from a base region. CONSTITUTION:When a transistor is changed into a cutoff state from an operating state, a drift current due to a high electric field caused by the cutoff becomes large at a central part 10 of a base when the carriers at the central part 10 of the base is poor. The central part is separated from a base electrode by a long distance. Energy P, which is consumed at this part per unit hour pert unit volume is equivalently expressed by P=E.J (where E is electric field vector and J is current density vector). Since J qmuNE [where (q) is raw quality of electric charge; mu is mobility and N is majority carrier density), after all, P qmuN¦E¦<2> is obtained. By preventing the concentration of the current, N does not become large. The energy consumption P is small. Thus the breaking strength of the element is improved. The concentration of the current at the central part of the base is prevented, and the energy consumed at this part can be decreased. As a result, the high withstand voltage can be implemented.

Title: Injection molding method using void insertion pin and mold for injection molding
Inventor: IIZUKA YOSHINOBU
IPC: B29C45/00
Filed: 1993-06-07
Abstract: PURPOSE:To obtain by injection molding a resin molded article having an excellent appearance wherein a defect such as a shrink mark due to shrinkage of resin is not made on the surface of a large-thickness part, and made up of the large-thickness part and a small-thickness part. CONSTITUTION:A void insertion pin 40 in the fore end of which a gas releasing part 44 tapered to be pointed is provided is provided at least at one place of a cavity 30 corresponding to a large-thickness part wherein a phenomenon of a shrink mark tends to occur. After molten resin 50 is full-shot into the cavity 30, a pressure gas is sent into the molten resin 50 from a pressure source 60 through the fore end of the void insertion pin 40, so as to induce a void neucleus 51. The void neucleus 51 grows to a void 52 of dimensions corresponding to the amount of the shrinkage of the molten resin 50 accompanying cooling and setting thereof. When the inside of the void 52 is made to communicate beforehand with the open air by operating a selector valve 64 on the occasion, the air is sucked into the void 52 by a negative pressure caused by the shrinkage. Since the shrinkage of the volume of the molten resin 50 is absorbed by the growth of the void 52, a defect such as the shrink mark does not occur on the surface and a resin molded article having little internal stress is obtained.

Title: Manufacture of silicon mask for x-ray exposure
Inventor: ITOU MASAKI
IPC: H01L21/027
Filed: 1980-09-30
Abstract: PURPOSE:To prevent a pattern from separation in substrate etching process and improve a manufacturing yield, by forming an absorption pattern made of Au or Pt with permalloy thin-film coating on an Si-substrate which has an X-ray penetration supporting layer. CONSTITUTION:An X-ray penetration supporting layer 2 composed of a B-diffused layer is provided on an Si-substrate 1 of (100) orientation. A permalloy film 3 (50- 1,000Angstrom ) and an absorption member 4 (1,000-2,000Angstrom ) made of Au or Pt are deposited thereon. After forming an etching mask 5 in a desired pattern, an absorption pattern 6 is formed by means of ion etching. The back surface of the substrate 1 is partially etched with a use of KOH solution, and an auxiliary supporter 7 is formed. The existence of permalloy 3 between the absorption member 6 and the penetration supporting layer 2 prevents separation of the Cr-film pattern etching. And a yield can be improved.

Title: Liquid crystal display unit
Inventor: ABE SHIYOUZOU
IPC: G09F9/00
Filed: 1977-11-14
Abstract: PURPOSE: To secure excellent lamp illuminaton effect as well as to obtain the highly stable quality by using the synthetic resin substrate with the fluorescent coloring matter mixed as the reflective plate.  
     CONSTITUTION: Fluorescent coloring matter 6 is mixed into synthetic resin substrate 5, and mirror surface reflective layer 8 is provided on a single surface or the side surface of the rellecting plate excluding window part 7 for the lamp illumination. As a result, part of rays entering the reflecting plate is reflected by layer 8 as conventional, and some of the incident rays excites the mixed fluorescent coloring matter. The electron of the excited coloring discharges the inter-level energy in the form of the optical energy when it returns to the original state, that is, the fluorescent light peculiar to the mixed coloring matter is emitted. Thus, the high-contrast color display of the desired color is ensured by selecting the fluorescent coloring matter. As the single surface and the side surface of reflecting plate 8 is finished in the mirror surface except for window part 7 for the lamp illumination, an effective reflection of the fluorescent light is obtained. Furthermore, the leak of the illumination light and the fluorescent light can be prevented for the lamp illumination, thus ensuring excellent lamp illumination effect as well as highly stable quality of the illumination.

Title: Apparatus for simply testing consolidation
Inventor: KATO FUJIO
IPC: C05C9/00
Filed: 1985-06-25
Abstract: PURPOSE:To enable a consolidation test simple to handle and testing a large amount of a sample at once, by inserting an object to be inspected between a lower press board and an upper press board and sliding both press boards along the inner surface of a cylinder main body. CONSTITUTION:An object to be inspected is inserted between a lower press board 4 and an upper press board 7 and the press board 7 is clamped by a clamp rod 9. When predetermined load was applied to the object to be inspected, that is, when, the graduations line of a predetermined wt. of a graduations rod 5 is exposed from a lower cap 2, clamping is stopped. Because predetermined load can be applied to the object to be inspected only by rotating the clamp rod 9, operation is extremely simple and a special tool or measuring device becomes unnecessary. Because this apparatus has a small size and the load applied to the object to be inspected does not change even if said apparatus is made vertical or horizontal, the apparatus can be stacked in a multistage fashion, for example, in a thermostatic tank and the consolidation test of a large amount of a sample can be performed at once.
