Title: Lcd contrast adjusting system
Inventor: TAKAHASHI SHUNJI
IPC: G02F1/133
Filed: 1994-09-27
Abstract: PURPOSE: To hold a good display contrast even when there is a severe difference between temperatures when starting of use and after the lapse of a fixed time by making a control automatically change operating voltage with the passage of time in accordance with a preset value for the fixed time from start of operation and to fix it as predetermined after the lapse of the fixed time. CONSTITUTION: For use in a vehicle in winter, e.g. with a severe temperature change, a user pushes a power switch 1 and also a contrast control switch 5. Then, an output voltage control mode is selected in a control 2, relatively high voltage is output during starting use and the voltage is gradually dropped with a time passed and variable voltage to be fixed voltage is output after a certain time passed. In this way, during a low temperature, that is a poor contrast, operation is kept at a high operating voltage, with heating gradually working and the contrast being gradually recovered, the operating voltage is dropped accordingly and the display contrast is held constant.

Title: Reduction in inhibiton of nucleic acid amplifying reaction
Inventor: DANIERU ERU UTSUDAADO
IPC: C12Q1/68
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To reduce the inhibition of the nucleic acid amplification in a biological sample by bringing the sample into contact with an anionic solid phase, bonding an inhibitor of nucleic acid amplification to the solid phase, separating the anionic solid phase bonded to the inhibitor of the nucleic acid amplification from the sample and then amplifying the nucleic acid in the sample.  
     SOLUTION: A sample is brought into contact with an anionic solid phase such as a cation exchange resin or an anionic siliceous substance so as to bond an inhibitor of nucleic acid amplification in the sample to the anionic solid phase, and the anionic solid phase and the inhibitor of the nucleic acid amplification bonded thereto are then separated from the sample. The nucleic acid contained in the sample is subsequently amplified to thereby reduce the inhibition of the nucleic acid amplifying reaction and amplify the nucleic acid in the sample containing the inhibitor of the nucleic acid amplification. When the inhibitor of the nucleic acid amplification is a glycoprotein, the sample is preferably pretreated with a glycosidase so as to completely remove carbohydrates from the glycoprotein and the removing treatment of the inhibitor of the nucleic acid amplification is then preferably performed in the anionic solid phase.

Title: Tip saw
Inventor: BABA KOICHI
IPC: B27B33/08
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce generation of a crack of a tip body, by retreating and tilting the head part of a tip body contacting edge facing to the direction of rotational cutting at a cemented carbide tip body-mounted recess part formed on an blade plate peripheral part, relative to the direction of rotational cutting compared with the base part. SOLUTION: A blade plate 1 is so composed that the peripheral part has a wave shape and that a pocket 14 for installing a tip body 2 on the side facing to the direction of rotation of a wave-shaped recess part 13. Especially, the pocket 14 is so formed that the head part of the rear edge (edge part facing to the direction of rotational cutting) is retreated and tilted (the rear edge line C is retreated by an angle θ relative to the radial line B from the center A) relative to the direction of rotational cutting compared with the base part. The tip saw is rotated in the prescribed direction and cuts an object with the cemented carbide tip body 2 on the head of the tip saw.  In this case, as the rear edge of the pocket 14 is retreated and tilted the force received by the blade plate 1 deviates and does not function as a strong compressive force to the tip body 2, therefore, generation of a crack on the tip body 2 is reduced remarkably.

Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of maximum cooling ability due to entrainment of high temperature air with cold air by arranging an auxiliary door part bending from the tip of a main body part to a hot air passage on the front end side of a face door main body part. SOLUTION: On the front end side of a door main body part 20a with a dimension sufficient for switchingly opening/closing a face opening part 17 and a communication passage 22, an auxiliary door part 20b is arranged while bent into an L-shape. In this case, the door main body part 20a, the auxiliary door part 20b, and a rotary shaft 23 are integrally molded of proper resin. In a maximum cooling time in a face mode, air around a heater core 9 is heated to a high temperature and raised toward a hot air passage 14 side because of natural convection.  In this way, however, the auxiliary door part 20b in the face door 20 shuts off the upper part of an outlet part of the hot air passage 14 in a face mode time, so that movement of high temperature air accumulated in the hot air passage 14 toward an air mixing chamber 16 side can be excellently prevented by means of the auxiliary door part 20b.

Filed: 1991-10-04
Abstract: PURPOSE:To prevent an existed compiling unit from being abolished even if the same name as the existing compiling unit is erroneously given in the preparation of the compiling unit. CONSTITUTION:A job control language execution part 1 checks and executes job control language. A first check part 2 compares a member name with the program name of an input library, which is shown by an input library name. When the member name is the same as the program name, control is shifted to a second check part 3. When they are not, an ID name error is displayed in a display 5. Then, the processing of the second check part 3 is to retrieve whether a compiling unit name prepared in the execution of job control language exists in a CU library 7. When it does not exist, execution is shifted to translation by a translation part 4. If it exists, the CU name error is displayed in the display 5 and execution is terminated as an error. The compiling unit generated by clearing two checks is outputted to the CU library 7.

Title: Battery pack
Inventor: TAKATSU KATSUMI
IPC: H01M2/20
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To realize thinning of a battery pack used in a portable information instrument. SOLUTION: This battery pack 1 is composed by storing a battery 3 and a battery protection device 8 between an upper case 2a and a lower case 2b of a pack case. The battery 3 is devised to be thinned by storing a generating element in an outer case formed by a laminate sheet. As the face of the lower case 2b, facing to the battery 3, is formed as a thin-walled elastic deformation face 15, the battery 3 does not expand so as to increase the thickness by a secular change, but deforms with keeping the plane state by elastic deformation, therefore, the occurrence of drum-shaped swelling of the battery pack 1 or bad influence on an instrument caused by the swelling can be prevented.

Title: Optical disk device
Inventor: INUI TOSHIHARU
IPC: G11B19/12
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To quickly discriminate the kind of a disk only by clamping without driving an optical pickup by detecting a quantity of light to be transmitted through a clamping area and comparing it with a value measured previously corresponding to the kind of such a disk. SOLUTION: When a plastic layer 1 of the clamping area 12 is specified as a polycarbonate of transmissivity 90%, and an adhesive layer 7 as transmissivity 80%, the whole light transmissivity is 72%. Then, the quantity of light transmitted through the clamping area 12 is detected by a photodetector such as a photodiode, etc., to take it out as a voltage. Subsequently, this voltage is compared with prestored voltages corresponding to such kinds of disks as a single substrate disk formed by one substrate and a disk formed by sticking more than one substrate together, so as to discriminate the kind of this disk. Then, since a detecting means for discriminating an optical disk is in the clamping area, space saving of the disk can be realized, and hence an information recording area is enlarged.

Abstract: PURPOSE:To aim at fuel economization and noise prevention by storing the optimum normal horsepower of a hydraulic pump for maximum speed at time of noload of an engine to each workhour mode of construction machinery in memory, and controlling this hydraulic pump and the engine at a mode changeover. CONSTITUTION:A normal horsepower curve setting group 9 of a hydraulic pump 4 and a desired speed setting group 10 for an engine 1 corresponding to the normal horsepower both are made inputtable into a memory 11.
