IPC: H01L23/14
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To obtain a production method of a flexible circuit board for TAB in which an oxide deposited during high temperature cure processing for suppressing production of whisker (acicular crystal) on the surface of tin plating being applied to a copper foil lead is removed. SOLUTION: The method for producing a flexible circuit board for TAB comprises a tin plating step, a sodium triphosphate neutralization step, a high temperature curing step, and a tin oxide removing step, i.e., a reprocessing step of sodium triphosphate. The processing conditions of sodium triphosphate are generally set as follows; concentration 1.5-3.0%, liquid temperature 50-60 deg.C and processing time 30-60sec. Since an oxide deposited on tin plating through high temperature curing can be removed, bondability to semiconductor can be enhanced and stabilized for following step.

Title: Method for growing oxide superconductor single crystal
Inventor: NOMURA SHIYUNJI
IPC: C01G29/00
Filed: 1988-08-19
Abstract: PURPOSE:To obtain a high-quality and large-sized Bi-based oxide superconductor single crystal by adding a flux consisting of a Pb compound to a raw material powder of a Bi-based superconductor and growing the single crystal according to a flux method. CONSTITUTION:A Bi-based superconductor powder or raw material powder capable of providing the Bi-based superconductor by heating is mixed with a flux consisting of a Pb-containing compound and the resultant mixture is kept at a high temperature, homogeneously melted and then annealed to grow a single crystal. Since Pb is used as the flux, a high Tc phase can be readily deposited to grow a high-quality single crystal without impairing superconductive characteristics. PbO, PbF2, PbCl2, etc., are used as the Pb-containing compound. If the concentration of the Pb compound is <=2%, the high Tc phase is hardly deposited and crystals will scarcely grow. Thereby, the mixing ratio of the flux to the oxide superconductor is preferably 2-30mol%.

Abstract: PURPOSE:To reduce the inter-channel frequency characteristic deviation due to a tuner and the deterioration in the frequency characteristic due to a standing wave generated at the antenna end by discriminating the frequency characteristic of a demodulated video signal so as to control the oscillation frequency of a local oscillator in the tuner. CONSTITUTION:A reference signal extracted by a waveform extraction circuit 4 passes a low frequency band pass filter 5 selecting a low frequency component of the signal and a high frequency filter 6 selecting a high frequency component of the signal respectively, detected by detectors 9, 10 and converted into a DC voltage. Then a difference 11 of the detected voltages is compared at a comparator 7 with a difference 13 of the detected voltages when the frequency characteristic of a reference voltage 12 (the difference 11 of the detection voltage when the frequency characteristic of the demodulated video signal 3 is a prescribed frequency characteristic) and the difference is fed to a local oscillator control signal 8 by using the difference as the control voltage to control the local oscillating frequency of the local oscillator in the tuner 1. Thus, the frequency characteristic of a demodulation video signal 3 is kept constant and a stable picture is obtained.

Title: Oil seal and its manufacture
Inventor: KOBAYASHI NOBUYUKI
IPC: F16J15/328
Filed: 1985-09-17
Abstract: PURPOSE:To prevent a leak of fluid when a shaft and a seal lip are in a stationary state, by providing a no-threaded region in a seal surface of the seal lip providing a threaded groove. CONSTITUTION:An oil seal 1 is equipped with a seal lip 2, and the oil seal 1 provides in its seal surface 10 a threaded groove 9 to be engraved.

Title: Shape conversion method, storage medium recorded with its conversion procedure and shape conversion device
Inventor: SAKAI MINORU
IPC: G09G5/36
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a shape conversion technique for easily generating a three- dimensional shape from a given two-dimensional graphic (character data of a bit map font, for example). SOLUTION: A two-dimensional shape expressed by a bit map is inputted and the three-dimensional shapes are made to correspond to the respective bits constituting the two-dimensional shape. In converting a two-dimensional shape expressed by a rectangular bit map of I×J into a three-dimensional shape, for example, '0' is inserted into 'i' and 'j' (step S1) and an appropriate three-dimensional shape is allocated to a bit Pij against all the combinations of 'i' (0<=i<=I) and 'j' (0<=j<J) (steps S2-S7). Thus, the original rectangular two-dimensional shape of I×J is converted into a three-dimensional shape by synthesizing them.

Title: High carbon steel having excellent blanking workability
Inventor: FUJITA TAKESHI
IPC: B23B27/14
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To obtain a high carbon steel having an excellent blending workability by allowing the steel to contain a specified amt. of C, regulating the average grain sizes of ferrite and carbides respectively to specified ranges and regulating the ratio of ferrite grains contg. no carbides to <=a specified value. SOLUTION: C forms carbides in the steel, applies hardenability and is incorporated by 0.2 wt.% for this purpose. The average grain size of ferrite is regulated to >=2 μm, and that of carbides is regulated to 0.3 to <1.6 μm. Then, the ratio of ferrite grains contg. no carbides is regulated to <=30%. By these, as the higher the average grain size of ferrite is, the softer the stock is made, and loads on working tools are reduced. Furthermore, by reducing ferrite grains contg. no carbides, their coagulation with working tools is reduced to suppress seizure. Moreover, by finely dispersing carbides, its frictional resistance at the time of blanking reduces, so that the wear of working tools is reduced and prolong tool lives.
