Inventor: OOE KATSUHIRO
IPC: H01L23/50
Filed: 1988-06-22
Abstract: PURPOSE:To improve a yielding rate and productivity of dies by providing a communicating path at a die so that its path has a blow-off port corresponding to the pointed end of a punch which is inserted into the lowest position and that the inside of an opening of the die communicates with the outside through the communicating path, thereby connecting the space in the opening of the die which is confronted by the punch to an air source. CONSTITUTION:A communicating path 13 is provided at a die 11 in such a way that its path has a blow-off port 13a corresponding to the tip of a punch 5 which is inserted to the lowest position. The inside of an opening 11d of the die communicates with the outside through the communicating path 13, and a space 12 in the opening 11d of the die which is confronted by the punch 5 is connected to an air source. Accordingly, a parted lead connecting piece 1c which is attached to the tip of the punch 5 is separated from the punch 5 by an air circulation which comes in the opening 11d of the die through the communicating path 13. Pressure welding of foreign materials to a lead 1a of a lead frame 1 is thus prevented and then leads of high quality improve a yielding rate and productivity of dies.

Inventor: KOBAYASHI TOMIYA
IPC: B65D25/34
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To improve press-processability by forming a coated film obtained by applying a paint containing wax and Butyl cellosolve and drying it, on the surface of aluminum or aluminum alloy. SOLUTION: A coated film obtained by applying and drying a paint containing wax and Butyl cellosolve is formed on the surface of aluminum or aluminum alloy. This coated film is constituted by applying and drying a paint containing wax and Butyl cellosolve after aluminum or aluminum alloy foil has been annealed after rolling. When a paint containing wax is applied in advance to form a coating film on the surface of an aluminum material, as the coating film serves as a lubricating film in a press-processing, a press-oil is not required. When only paint containing wax is applied, the appearance deteriorates, but when Butyl cellosolve is contained in the paint, deterioration of the appearance can be solved.

Abstract: PURPOSE:To increase the water absorbing speed of a water removing roller for sheet etc. by providing the roller having water absorptiveness with an anisotropical water penetration film, which allows penetration of water only in a single direction, and by orienting the water penetrative direction toward the core of roller. CONSTITUTION:This water removing roller is made in such a construction that a water absorptive member 12 is laid over a core 13 consisting of metal or plastics, and thereover an anisotropical water penetration film 11 is arranged in such a way that the direction of water penetration is oriented toward the core of roller. As such as anisotropic penetrating film 11 is used films in different materials designed for dialysis, ion exchange, reverse penetration and out-of-limit filtration, or otherwise a functional high polymer film or a vesical diaphragm. To provide drive motive for this anisotropic water penetration, paper impregnated with salts suitable for the film for the purpose, for ex. table salt in high concentration, is used for said water absorbing member 12 on the core side. Thus the water absorbing speed can be made 3-5 times as high as figures available from any conventional arrangement, and thus this is suitable for continuous high-speed processing and capable of processing in a quantity 3-5 times as great as the conventional saturated processing unit.

Filed: 1990-06-13
Abstract: PURPOSE:To measure density and the amount of moisture highly efficiently and stably by using a phoswich-type detector which is constructed by combining an NaI scintillator and a plastic scintillator optically with one photomultiplier tube. CONSTITUTION:A gamma-ray and a fast neutron-ray radiated from a radiation source 1 are transmitted through a substance 20 to be measured and are detected by a plastic scintillator 15, while the gamma-ray is detected also by an NaI scintillator 4. A pulse- shape discriminating circuit 16 separates a detection signal by the scintillator 15 from a detection signal by the scintillator 4 by utilizing a difference in a pulse rise time between the two signals. Next, the counting rate Np per unit time of the separated detection signal from the scintillator 15 and the counting rate Nc of the detection signal from the scintillator 4 are counted. Then, CPU 19 distributes the counting rate Np to a gamme-ray contribution part Ngamma and a fast neutron-ray contribution part Nn on the basis of a distribution ratio determined by the construction of a phoswich-type detector 3 and the radiation source 1m and calculates the amount of moisture of the substance 20 to be measured on the basis of the counting rate Nn of the fast neutron-ray and the density on the basis of the counting rate Ngamma of the gamma-ray.

Filed: 1979-12-03
Abstract: PURPOSE: To prevent the misreading of the information, by providing a counter the initial value of which is decided in accordance with the signal supplied from a storage device and a means which reads the above-mentioned signal in separation from the prescribed information and then renewing the initial value by a comparison given between the comparison information obtained from the read-out information and the information to be compared which is stored previously in the storage device.  
     CONSTITUTION: The information recorded to the magnetic disk 52 is supplied to the RD terminal of the disk controller 51 via the waveform producing circuit 53 and in synchronization with the fundamental clock signal as well as to the counter 55. The counter 55 takes out the initial value from the latch circuit 54, and the W signal is delivered only for the prescribed counting period after the initial value. The controller 51 separates the input signal of the RD terminal into the reference signal and the data bit D. The comparison information detecting means 56 produces the comparison signal from the D signal, and this comparison signal is compared with the memory information read out to the detecting/holding means 57 of comparison to be compared through the comparing means 58. Thus the contents of the length circuit 57 are changed by the initial value changing means 59. As a result, the misreading of information is avioded.

Abstract: PURPOSE:To prevent occurrence of sagittal image surface inflection, by respectively providing a positive and negative lenses in front of and rear of a cylindrical lens and making a luminous flex incident to the cylindrical lens frontally by bending the flux before and after the cylindrical lens only. CONSTITUTION:A scanning optical system containing the surface inclination correcting optical system of a rotating polygon mirror 4 is composed of a positive lens 1, cylindrical lens 2 having a positive power in the direction vertical to the deflecting surface, and negative lens 3, successively from the reflecting point of the polygon mirror 4. A luminous flux L deflected by the reflecting surface of the rotating polygon mirror 4 is refracted inward by the positive lens 1 and made incident on the cylindrical lens 2 almost frontally. The luminous flux projected from the cylindrical lens in parallel with the optical axis is again expanded outward by the negative lens 3. Thus a sufficient scanning width can be obtained. Quantitatively, it is possible to control the sagittal image surface inflection and tangential image plane inflection to sufficiently small values by making the curvature of each lens surface optimum.

Title: Sheet feeder
Inventor: OGANO AKIRA
IPC: B65H3/52
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To provide a sheet feeder capable of discharging sheets one by one when sheet double feeding occurs. SOLUTION: When a sheet S is fed, a second upper roller 22 is rotated in a rotational direction opposite to the sheet feeding direction. Accordingly, when the double sheets S are fed overlappingly each other, a flexure of the sheets S is generated. The flexure of the sheets S is detected by a sensor 31 so that the double feeding of the sheets S is detected. When the sensor 31 detects the double feeding of the sheets S, a second lower roller 21 is rotated in its normal rotational direction and the second upper roller 22 is rotated in the opposite rotational direction. As a result, of the overlapping sheets S, the sheet S on the second lower roller 21 side is discharged, and then, the sheet S on the second upper roller 22 side is discharged by switching the rotational direction of the second upper roller 22 to its normal rotational direction.
