Title: Forming method of can body
Inventor: YAGUCHI JIROU
IPC: C09J5/10
Filed: 1980-03-18
Abstract: PURPOSE: To prevent damaging of the surfaces of joint parts and exposing of adhesives and make sealing sure by interposing an adhesive in the joint part of a can barrel blank, hammering the same and locally heating the joint part, then pressing said part with cooled hammers.  
     CONSTITUTION: An adhesive 2 of thermoplastic synthetic resins or the like is interposed in the side edges of a can body blank 1, and the side edges are bent and combined. The joint part is striken with hammers 3, 4, at ordinary temp., whereby it is press-joined. Thence, the adhesive part is partially heated with high-frequency heating coils 5, etc., to melt the adhesive. Following to this, it is pressed and cooled by using hammers 6, 7 cooled to around -30°C and while the shape of the joint part is correctly held, the temp. is lowered down to the temp. necessary for the adhesive to set. By this method, the metallic cans having good quality are mass-produced at high yields.

Filed: 1983-03-04
Abstract: PURPOSE:To reduce the load on a CPU and to minimize the rotation wait time in reading operation by specifying a processing range and the number of constituent blocks of repetitive data and writing data on the 2nd and succeeding tracks while making a shift in starting position. CONSTITUTION:A repetitive data writing/reading circuit 22 controls a data buffer 23 while transmitting and receiving control information to and from a channel interface circuit 24 and a main control circuit 21. Namely, the number D of blocks within the processing range and the number U of repetitive data which can be retried on the 1st track are calculated firstly. Then, U pieces of repetitive data are written on the 1st track. In this case, the number of tracks to which writing should be performed is left, U pieces of repetitive data are written from the position which is Z sectors (as many as sectors to be shifted in writing between adjacent tracks) from the starting repetitive data on the last track. Consequently, starting sectors of respective repetitive data on respective tracks are dispersed at a maximum and the rotation wait time is minimized to reduce the load on the CPU.

Title: Optical information recording tape
Inventor: MIYAMOTO NORIFUMI
IPC: G11B7/2433
Filed: 1985-02-22
Abstract: PURPOSE:To obtain an information recording tape which permits rewriting by using a metal or alloy having at least two kinds of phases in a solid phase state and utilizing the change of the crystal structure arising from the transformation of said phases. CONSTITUTION:The recording medium consists of the metal or alloy which has at lest two kinds of the crystal structure in the solid state, maintains the crystal structure of one temp. region in the other temp. region and/or induces the volumetric changes different from each other in the crystal state. For example, a large difference in the spectral reflectivity of a reddish copper color and golden color is observed at about 500nm when the tape-shaped recording medium deposited by evaporation with a 14wt% Al-4wt% Ni-Cu alloy is subjected to heating and quick cooling and to heating and slow cooling. The information processing is therefore possible at this wavelength. The recording, reproduction and erasure of information are executed by the laser spot stopped down to 1.0 micron to several microns by an objective lens. The difference between recording and erasure is obtd. by varying the intensity of laser power.

Abstract: PURPOSE:To surely execute a breaking and cutting operation of a weak part without producing harmful broken pieces after a magnetic band has been wound by a method wherein a plurality of magnetic bands in which weak parts have been formed are piled up and wound. CONSTITUTION:Magnetic bands 40A to 40G are wound after weak parts 41A to 41G have been formed by the use of weak part forming mechanisms 36A to 36G at each prescribed position in a winding direction; after that, the weak parts 41A to 41G are broken and cut; a one-turn cut-type wound core is manufactured. During this process, a plurality of the magnetic bands 40A to 40G in which the weak parts 41A to 41G have been formed are piled up and wound. Since the plurality of the magnetic bands 40A to 40G are piled up and wound in this manner, a strength during their winding operation is enhanced as a whole; a sufficiently strong tension can be applied to the magnetic bands 40A to 40G during their winding operation; a swollen winding shape is not caused. Thereby, the weak parts 41A to 41G can be broken and cut surely without producing harmful broken pieces after their winding operation.

Title: Thrust bearing device
Inventor: WATANABE SHINTARO
IPC: F16C33/10
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To prevent generation of abnormal wear in the inner circumferential part of bearing by forming a ring-like groove having a smaller radius than that of the inner circumference of bearing on a collar slide surface, and forming oil discharge holes opened at the outer surface of collar while communicated with the groove of collar. SOLUTION: A ring-shaped groove 20 of a collar 4 is positioned on the inner circumferential side of inner circumferential shroud 11 of a thrust bearing 6 on the load side. Oil discharge holes 21 are formed in the collar 4 in communication with the groove 20 and the hole 21 is opened to the outer circumference thereof. Lublicant flowing out between the shroud 17 and the collar 4 enters and the lublicant is discharged through the discharge hole 21 by the action of centrifugal pump. The lublicant leaked out to the inner circumferential side of bearing by the above action is liable to flow to the groove 20, and thereby it does not stay in a gap 13 between the bearing 6 and a spacer 2.  Accordingly the lublicant is not subjected to viscous friction in the gap 13 so that the temp. thereof becomes high, resulting in elimination of abnormal wear in the innercircumference of thrust bearing on the side of load. leading to improvement of reliability.

Abstract: PURPOSE:To obtain high transfer efficiency and high linearity, by constituting a semiconductor with a tap, of N-number of independent charge transfer element (CTD). CONSTITUTION:A signal applied to an input terminal 26 is sampled at every constant period T by an input part 21-k (k=1-N), and is converted to charge at the same time. Subsequently, the signal charge concerned is injected to its corresponding transfer part 22-k, and also moves a transfer stage 25 by one stage each at every constant period T. The signal charge which has reached a tape circuit 23-k at every CTD is converted to voltage, and is led to the outside of a CTD 20 through a tap terminal 24-k. An output signal x(nT-kT) from each tap terminal 24-k, is multiplied by a weight coefficient wk by the first multiplier 28-k, its multiplied result is added by an adder 29 and becomes an output signal (y), and is fetched from an output terminal 27. A comparator 130 compares the output signal (y) with the referential potential, generates an output (a), subsequently subtracts (a) from (y) by a subtracter 131, and an error signal (e) is obtained. Subseqently, the weight coefficient wk is controlled so that the error signl (e) becomes zero.

Abstract: PURPOSE:To obtain smooth acceleration in an exhaust gas recirculating device, operating a recirculating valve controller and air-fuel ratio regulating valve at accelerating  operation, by delaying operation of the controller from operation of the regulating  valve. CONSTITUTION:If a throttle valve 6 is rapidly opened at acceleration, the atmospheric pressure in the upstream acts on the first pressure chamber 18a, simultaneously  a check valve 18d is closed, and a passage 19 is closed by a valve member 18c with  negative pressure in the second pressure chamber 18b, then the negative pressure in the chamber 18b is leaked to the atmosphere from a valve 18f, with delay of a certain  time, the valve member 18c is opened to release the passage to the atmosphere. Accordingly, at acceleration, intake negative pressure is applied to a passage 15 and to negative pressure chambers in valves 13, 16 via passages 14, 17, and flowing air from the  valve 13 to a pressure regulating chamber 12a is stopped to increase negative pressure  and increase the opening of an exhaust gas recirculating valve 9, then an air amount  from the valve 16 to an air bleed device 4 is decreased, thus a fuel amount delivered from a nozzle 3 is increased. Here the spring constant of a spring 13h is higher than  16h, and this causes close timing of the valve 13 to be delayed from 16, then a recirculating amount is never increased before increase of a fuel amount.
