Title: Tire and manufacturing method thereof
Inventor: ONO KATSUHIRO
IPC: B60C5/00
Filed: 1980-06-16
Abstract: PURPOSE: To reinforce an annular hollow body, to maintain a fixed shape and to  attain convenience for forming a tire, by winding a reinforcing material on the peripheral surface of the annular hollow body.  
     CONSTITUTION: An annular hollow body 2 is placed in a split mold 6 for forming a tire. Air is introduced under pressure into the hollow body 2 through an air inlet port 8 to maintain a fixed shape. A liquefied rubber compound is injected into a cavity 9 in the split mold 6 through an injection port 7. The liquefied rubber compound flows in along the outside surface of the hollow body 2 and fills up the cavity 9 of the split mold 6. To prevent voids from being made in the body of the tire, air is introduced again under prescribed pressure into the hollow body 2 and the liquefied rubber compound is then set. Since a reinforcing material 5 impregnated with a liquefied rubber compound is previously wound on the outside of the hollow body 2, the reinforcing material 5 and the liquefied rubber compound introduced in the cavity 9 are integrally conjoined to each other when the introduced liquefied rubber compound is set. After the tire is molded, the air is discharged out of the hollow body 2 and the split mold 6 is released to take out the tire.

Title: Multiple light transmission body made of quartz glass
Inventor: HAYAMIZU HIROYUKI
IPC: G02B6/06
Filed: 1987-04-01
Abstract: PURPOSE:To reduce the diameter of a titled light transmission body and to provide the sharper image quality by forming the 1st clad layers on cores to the refractive index lower than the refractive index of 2nd clad layers and specifying the occupying ratio thereof in the quartz glass base material for the light transmission body at 5-25%. CONSTITUTION:This light transmission body is made into the structure in which many pieces of the quartz glass base materials for the light transmission body each having the 1st clad layer 22 and the 2nd clad layer 23 successively on the core 21 consisting of the pure quartz glass are welded to each other. The 1st clad layers 22 are formed to have the refractive index lower than the refractive index of the 2nd clad layers 23 and the occupying ratio thereof in the quartz glass base material for the light transmission body is set at 5-25%. The problems of crazing and overflowing do not arise in spite of using the doped quartz glass of a high coefft. of expansion obtd. by compounding a large amt. of dopant therewith as a material for constituting the 1st clad layers 22, when the 1st clad layers 22 are the thin layers having <=25% occupying ratio in the quartz glass base material for the light transmission body. In addition, a larger difference in the refractive index from the cores 21 can be adopted by lowering the refractive index of the 1st clad layers 22 and the transmission of the sharp image is permitted even if the total thickness of the 1st clad layers 22 and the 2nd clad layers 23 is made smaller than the clad layers of the conventional light transmission body.

Title: Mos type semiconductor device and manufacture thereof
Inventor: HIRUTA YOICHI
IPC: H01L21/8238
Filed: 1989-03-31
Abstract: PURPOSE:To miniaturize an element and form a device itself compactly by allowing one edge of a diffusion source layer to contact an impurities diffusion layer and the other to hang onto a field oxide film by patterning after diffusion for achieving a diffusion layer leading electrode. CONSTITUTION:An impurities diffusion layer 15 is formed by the diffusion of a diffusing object from a diffusion source layer 14 such as a metal and a semiconductor accumulated on the surface of a semiconductor layer 10. One edge of the diffusion source layer 14 contacts the impurities diffusion layer 15 by patterning after diffusion. While the other edge hangs on a field oxide film 12, thus forming a diffusion leading electrode 14b. Namely, a gate electrode 13e is not formed by ion implantation and the gate electrode 13a needs not be thick considering the influence of ion implantation to the element region due to ion implantation. Furthermore, since the ion impurities diffusion layer 15 is formed by diffusion of a diffused object from the diffusion source layer 14, the junction depth becomes shallow. Thus. it becomes possible to miniaturize an element and form a device itself compactly.

Title: Liquid drop-dropping apparatus
Inventor: TAKADERA YOSHIKAZU
IPC: B01L1/00
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To correctly adjust the amount of one drop of liquid and surely drop one drop of liquid by setting a branch pipe having an air reservoir at a buret and switching a two-way valve thereby dropping the liquid drop by a pressure of the air reservoir. SOLUTION: A two-way valve (e) is registered with a position where a buret pipe (a) upper than a branching start end of a branch pipe (d) communicates with the branch pipe (d). As a result, a liquid in the pipe (a) is supplied to an air reservoir (c) via the branch pipe (d) owing to a pressure difference between liquid levels in the pipe (a) and air reservoir (c). At this time, the air in the air reservoir (c) is compressed thereby to balance the pressure difference of the liquid levels in the pipe (a) and air reservoir (c), so that a fixed amount of the liquid is supplied. Thereafter, the two-way valve (e) is turned 90 deg. in the counterclockwise direction. Since the branch pipe (d) is communicated with a buret pipe (b) lower than the branching start end of the branch pipe (d), the liquid is discharged until the air reservoir (c) is turned to a normal pressure.  When the fixed amount of the liquid is discharged and the pressure in the air reservoir (c) is balanced with the atmospheric pressure, the liquid is not discharged any more.

Title: Detecting system for disconnection in digital output circuit
Inventor: CHIBA YOSHIHIRO
IPC: G01R31/02
Filed: 1980-06-17
Abstract: PURPOSE:To reliably detect a disconnection of power output elements with a simple circuit, by connecting a resistor to each of power output parts in parallel to provide a detecting circuit to detect the change in resistance resulting from the disconnection of power output elements. CONSTITUTION:When one of drivers DR0-DR3 is on (off), and the one of relays RY0-RY3 which corresponds thereto has been disconnected, the potential at one of points P0-P3 is extremely lower than before the disconnection of the relay, and the output of one of inverters INV0-INV3 becomes H. Consequently, an AND circuit is opened to report abnormality. In this case, because the potentials at the points P0- P3 are independent of the on and off of the drivers DR0-DR3, the disconnection accident of the relays can be detected independently of the on and off of the drives. By such a constitution, the disconnection of power output elements can be reliably detected with a simple circuit by using inexpensive parts or elements.
