Abstract: PURPOSE:To achieve an efficient dissolution of a reaction reagent in a simple structure and mixture/agitation with a liquid body to be inspected by forming a shape of a container which is opened upward and providing a pocket with a reagent storage portion at a bottom portion and an inclined bottom wall at one portion of a side wall. CONSTITUTION:A cuvette 10 is formed in a shape of a container which is opened upward entirely, its material is allowed not to react with a reagent with a certain degree of hardness and is suited for mass production relatively, and then it is formed to be disposable. A pocket 13 with a reagent storage portion 11 at the bottom portion and an inclined bottom wall 14 which becomes higher toward an outside at one portion of a side wall is provided. This cuvette 10 is set so that the pocket 13 faces an outside in rotary radius direction of a rotor 30 for reaction. Then, a reagent for reaction and a liquid inspection body are filled into the storage portion 11 and then it is pushed and then lifted toward an outside in rotation radius direction by centrifugal force due to rotation of the rotar 30 and then is retained at a specific position within the pocket 13. It drops naturally due to rotation stop and elevation is repeated due to repetition of rotation and stop, thus enabling the reagent to be dissolved, mixed, and agitated.

Title: Video signal recorder
Inventor: HIRASAKA HISAKADO
IPC: H04N9/83
Filed: 1992-02-07
Abstract: PURPOSE:To attain excellent recording by effectively utilizing a maximum recording dynamic range of a magnetic recording medium regardless of a level of an input chroma signal. CONSTITUTION:A video signal recorder applying a chroma signal to low frequency conversion and recording the converted signal onto a magnetic recording medium 16 is provided with a peak AGC circuit 32 detecting a peak level of the chroma signal for each prescribed period and controlling the gain accordingly at a post-stage after a burst AGC circuit 9 of a chroma signal circuit system and a recording level of a peak level is kept to a recording level upper limit V0 of the medium 16 for each prescribed period. Since the recording level of the peak level of the chroma signal for e.g. each one field period is subjected to gain control so as to reach the recording level upper limit V0, the maximum recording dynamic range V0 of the medium 16 is utilized effectively and excellent recording is attained regardless of the input chroma signal.

Title: Die for molding mount bracket made of resin
Inventor: HIDAKA TSUGUHITO
IPC: F28F21/06
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To restrain a rise of manufacturing cost of a mount bracket from rising while allowing the bracket to be applicable to various sizes of cores by forming a protrusion protruding toward the depth direction of a recess into an injection space at a portion corresponding to a bent part of the mount bracket in the injection space. SOLUTION: When a molten resin is delivered from an injection port 106 under a predetermined pressure, the resin is filled into an injection space 105. After completion of charging of resin, the resin is hardened and formed into a plate-shaped member. Since a mount bracket is formed by bending the plate- shaped member of resin, the shape of a die is simplified in comparison with a case in which a mount bracket having a cross-section formed into a U-shape beforehand is molded, and hence inferior dimensions and molding can be avoided. As a result, yield can be improved and hence manufacturing costs of mount brackets and also heat exchangers can be restrained from rising.

Title: Bar code reader
Inventor: MOTO KIYOSHI
IPC: G06K7/10
Filed: 1988-02-03
Abstract: PURPOSE:To read bar codes at a high speed by deciding the prescribed number of pseudo bar code signals if existing within a single scan as the real bar codes and immediately fetching these codes equivalent to one character. CONSTITUTION:Both bar and scan signals are supplied to a latch 2 from a signal detecting circuit 1. At the same time, the count data received from a self-driving counter 115 is also supplied to the latch 2. In this latch 2, the data b0-b13 are equivalent to the count data, i.e., the output of a counter 115 with the data of 16 bits, for example, together with the data b14 serving as the repetitive signals of '0' and '1' for each bar as the bar signals, and the data b15 serving as the repetitive signals of '0' and '1' for each scan as the scan signals respectively. Then the bar codes are read and the identity of bar codes is decided based on the number of aggregates of count values that are supplied during the change of the data b15. Thus the real bar codes are decided when the number of said aggregates are equal to the prescribed value.

Abstract: PURPOSE:To provide a combustion device capable of safely and surely detecting the danger of the exhaust emission after combustion in a combustion chamber such as a cylinder of the engine. CONSTITUTION:Carbon monoxide in the exhaust emission is detected by providing a gas detector 10 on an exhaust pipe 204 of the engine 61 (a combustion device 200) of an engine type heat pump 600. The air fuel ratio to a combustion chamber 203 is controlled by the detected output.

A control part 300 detects the condition of change of the output value Vkh in the purified condition and the output value Vki in the detected condition. When no outputs are given on both the output value Vkh in the purified condition and the output value Vki in the detected condition, an alarm is given that the gas detector 10 is in the disconnected condition. When the difference between the output value Vkh in the purified condition and the output value Vki in the detected condition is below the prescribed value, an alarm is made that the gas detector 10 is in the deteriorated condition.

Title: Injection molding machine
Inventor: KOYAMA HIDEKI
IPC: B29C45/84
Filed: 1994-01-27
Abstract: PURPOSE:To provide injection molding machine eliminating a labor of operating an emergency stop switch and an excessively large quantity of motion required of an operator to open a safety door and more immediately stopping an actuation of each part for ensuring the safety even in the case of identifying an abnormality in a semi-automatic operation, such as a condition setting of an experimental mold. CONSTITUTION:A limit switch SW3 is disposed opposedly to a tongue of a knob 10. Whether the knob 10 is operated is detected by a rocking position of the tongue. If a safety door 3 is not actually opened, an emergency stop function of an injection molding machine is actuated when the knob 10 is operated. In this manner, a time required from identification of an abnormality to an emergency stop is shortened. A force for actually moving the safety door 3 itself and such a work that a hand gripping the knob 10 is released to operate an emergency stop switch 7 are eliminated. Especially, a required time for an emergency stop in the case of identifying an abnormality in a semi-automatic operation, such as a condition setting of an experimental mold, can greatly be shortened.

Abstract: PURPOSE:To uniformly obtain surface roughness of a workpiece in its work surface removing deflection of a crossing part for its rotating axial center by forming a side surface in an obtuse angle for a ground surface and preventing abrasive grains from falling off from the crossing part between these ground surface and side surface further dressing this crossing part. CONSTITUTION:A grinding stone 7 places its cut-in direction almost vertical for a ground surface 3, and in a condition that the grinding stone 7 is mounted to a main spindle 10, crossing parts 6a, 6b of side surfaces 4, 5 and the ground surface 3 perform dressing by dressing wheels 8a, 8b.

By the grinding stone 7 thus performing dressing, a silicon wafer 1 can be ground in uniform surface roughness. Here the stone 7 forms its side surfaces 4, 5 in obtuse angles alpha, beta for the ground surface 3. Consequently, abrasive grains can be prevented from falling off from the crossing parts 6a, 6b of these side surfaces 4, 5 and ground surface 3.
