Title: Mim liquid crystal panel
Inventor: YAZAWA SATORU
IPC: H01L21/822
Filed: 1988-11-22
Abstract: PURPOSE:To produce a MIM liquid crystal panel in a short process with a good yield and to improve the reliability and the quality by forming the lower electrode of a thin film capacity with tantalum and tapering tantalum by etching and forming a part of a dielectric film of the thin film capacity as a tantalum oxide film where tantalum is subjected to anodic oxidation.

A thin film capacity 14 is formed under a picture element electrode 74, and tantalum is tapered by etching and is subjected to anodic oxidation, and the tantalum oxide film is formed on it by active sputtering. Disconnection due to a step is very reduced because the picture element electrode 74 is tapered through being formed on the tantalum oxide film, and an insulating film is fine and short-circuit between the picture element electrode 74 and the lower electrode (tantalum) of the thin film capacity 14 is very reduced because the anodic oxidation film is used. Thus, the panel which has a high reliability and is superior in temperature characteristic is produced with a good yield in a short process.

Title: Structure of tire whose air chambers are constituted with two layers by means of partition
Inventor: TENKAI KOJI
IPC: B60C11/16
Filed: 1991-08-26
Abstract: PURPOSE:To make travel on an iced or snowed or muddy road possible by conducting the changeover of general purpose automobile tires by simple operation as occasion demands so that they may have the same function as that of studless tires, spike tires or tires with chains, and also to realize tire structure which can maintain a necessary air amount so that a tire function may not be lost against a puncture during travel. CONSTITUTION:The inside of the air chamber of an automobile tire is made to be in two layers by providing a partition circumferentially, and arrangement is made so that pressure may be changed individually by fitting an air injection valve to each air chamber. When travel is made on an iced and snowed road or a muddy road, the pressure of a ground contact side air chamber 6 is lowered, and thus, grip force is increased, as a tire section shape is bent due to load and a ground contact area becomes large. Simultaneously, a studs 8 embedded at a shoulder portion 2 are brought into contact with the ground, and a spike function is obtained. As for a puncture during travel, it is so structured that even if an air chamber 8 out of the two air chambers is deflated, the air chamber 7 is not affected.

Title: Electrically operated fan
Inventor: TOYOSHIMA HISANORI
IPC: F04D29/16
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To prevent circulation of air flow while suppressing the increase in friction loss by disposing a sealing member exhibiting a specific value of elastic modulus at a position opposite to the end rim of a suction opening of the front shroud of a fan casing so that the sealing member is in contact with the end rim of the suction opening during assembly, and cut off thereby resulting from rotation of the impeller. SOLUTION: When assembling this electrically operated fan, a sealing member 35 is elastically deformed in pressure contact with a suction opening end rim portion 33c of a front shroud 33a of a centrifugal impeller 33. By the rotation of the centrifugal impeller 33 during the first operation of this electrically operated fan, the sealing member is cut off by the end of the suction opening end rim portion 33c of the front shroud 33a. Thus, the sealing member 35 and the suction opening end rim portion 33c of the front shroud 33a slightly contact with each other in a slightly slidable state. The sealing member 35 is made of a member exhibiting the elasticity modulus ranging from 20 to 50 kg/cm<2> . If it is less than 20 kg/cm<2> , the handling capability and assembling accuracy are lowered.  If it is greater than 50 kg/cm<2> , problems including deformation of the centrifugal impeller 33 or the mechanical loss when it is pressed arise.

Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To appropriately incorporate an inspection process of electric appliances in an assembling line by judging the quality of the electric appliances by whether or not they are within the prescribed range obtained based on prescribed continuos physical values measured beforehand. SOLUTION: If an environment temperature, etc., of an inspection system are varied, a judgment reference value which is applied in judging some external machine cannot be simply applied in judging another external machine. Therefore, a sample electric current value of a target appliance to be judged is set to a judgment target value Sn, and electric sample values obtained by tracing back in the past are set to S(n-1)-S(n-9). A judgment reference value of a judgment target value Sn is calculated based on the reference data S(n-1)-S(n-9).
