Abstract: PURPOSE:To allow production without brazing Al materials and jigs and without sticking carbon to the surfaces of the Al materials by using the jigs having ceramics surface on the surfaces which come into contact with the Al materials as the jigs which come into contact with the Al materials. CONSTITUTION:Al tubes 10, fins 11 and header tanks 12 are first prepd. and are combined to the form of a heat exchanger. The fins 11 and the jigs 13 for shape retention consisting of SiC, Si3N4 or ceramics such as Al2O3 are disposed in all the spacings between the adjacent tubes of the assembly. A flux consisting of an aq. suspension of a complex mixture composed of AlF3 and KF as raw materials is coated on the assembly and the assembly is heated in an inert gaseous atmosphere, by which the tubes 10 and the fins as well as the tubes 10 and the header tanks 12 are brazed. The heat exchanger is thus produced. The tubes 10 and the jigs 13 are not brazed in this case and the surfaces of the tubes 10 are clean.

Title: Back all right (automobile tiltable telescopic corner pole)
Inventor: NAKADA JUNICHI
IPC: B60R21/00
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To avoid damaging an automobile or an object by bringing an automobile being parked contacting with an obstacle. SOLUTION: An automobile tiltable telescopic corner pole for use on the front and the rear bumpers of an automobile comprises an antenna. The antenna is connected with a thin wire lead to the driver's seat and then mounted with a lever, which allows the operation of the antenna from the driver's seat to hold it vertical with a spring at the running of the automobile and horizontal at the parking thereof. Pulling the lever brings horizontal the antenna which then retracts when contacting with an object. Pulling back the lever brings the antenna extended. The antenna is telescopically structured and thus easily telescopes with the spring mounted in the intermediate portion thereof. When the horizontally held antenna retracts, the spring in the antenna-guide cylinder is compressed and depresses the switch of a buzzer to bring its electrodes closed and thus generate a buzzer.

Title: Martensitic stainless steel
Inventor: UEHARA NORIOKI
IPC: C22C38/20
Filed: 1980-10-22
Abstract: PURPOSE: To obtain a stainless steel enabling cold heading, has good workabilities, exhibits high strength after heat treatment thereof, and is anticorrosive property more than a conventional one, by specifying the composition of a steel.  
     CONSTITUTION: The martensitic stainless steel consists of 0.15W0.50% of C, 0.50% or more of Si, 0.30W2.00% of Mn, 1.0W3.0% of Cu, 0.20% or more of Ni, 13.0W 17.0% of Cr, 0.02W0.10% of N and balance of Fe and unavoidable impurities. To obtain hardness and strength higher than SUS410, C is required in an amount of the minumum, but of the amount exceeds the maximum, the cold heading properties and the anticorrosion properties will be deteriorated. The Cu seves a principle role to make up the lowering of the anticorrosiveness resulted from the higher C content, and the amount of Cu is required to be equal to the minumum or more, but if it exceeds the maximum, it will result in season cracking. Although the Ni improves the anticorrosion, the amount cannot be increased because that will adversely affect the cold rolling. To improve the anticorrosion, the amounts of Cr and Cu will be increased, and the minimum is required, but if the amounts exceed their maximums, the hardness and strength will be lowered. A screw of the present steel exhibits high strength that endures self-tapping etc.

Further, since the duration time of SS1 is set so that it can be given as required to standstill the motor 1 at a new step position for the braking torque, then the print head 5 is stopped newly to the digit without residual vibration.

Title: Memory control circuit
Inventor: TSUDA TOSHITAKA
IPC: G11C7/00
Filed: 1982-08-27
Abstract: PURPOSE:To simplify the constitution of an address supply/counter circuit of a memory which performs writing for each row and reading for each column of the n-row/n-column matrix data, by selecting and combining the outputs of a pair of counter circuits to form addresses. CONSTITUTION:Selecting circuits SEL1 and SEL2 are controlled via a control circuit CTL so that the clock count output of an n-notation counter circuit CNT3 is used to a lower bit and the output of an n-notation counter circuit CNT4 is used to an upper bit respectively. Thus an address is formed, and an access is given to the row and the column of an (nXn) matrix memory MEM with upper and lower bits of above-mentioned address respectively. Then the writing is carried out for each row. In the same way, a reading address of each column is formed by changing the combination of the outputs of circuits CNT3 and 4. As a result, it is not needed to use a counter which forms the writing and reading addresses independently of each other. This simplifies the constitution of an address supply/counter circuit by common use.
