Title: Television receiver
Inventor: KUREHA TAKESHI
IPC: H04N3/16
Filed: 1980-10-09
Abstract: PURPOSE:To enable to make a horizontal scanning frequency n-times, in keeping the jumping scanning relation of a reception signal, by providing a means which adjusts scanning interval arbitarily, in a TV receiver which converts the horizontal scanning period into that of 1/n for display. CONSTITUTION:A synchronizing separation circuit 5 separates a synchronizing signal obtained from a demodulation circuit 2 into a vertical synchronizing signal and a horizontal synchronizing signal, and the former is applied to a vertical deflection circuit 6 and the latter is given to a multiplication circuit 7 and a signal generating circuit 9. The circuit 9 generates a pulse voltage of 50% duty cycle from the horizontal synchronizing singal. An amplitude generating circuit 10 adjusts this pulse voltage and supplies it to a superimposing circuit 12. On the other hand, a convergence signal generating circuit 11 produces a signal for convergence and supplies it to the circuit 12. In this case, the circuit 10 selects the polarity of the pulse voltage to a polarity giving opposite deflection to the vertical scanning signal, and supplies it to the circuit 12 after adjusting the amplitude of pulse voltage to an amplitude necessary to move the scanning line by 1/2 of the scanning line interval.

Title: Automatic chemical analysis
Inventor: TSUBAKIMOTO HIROKO
IPC: G01N33/543
Filed: 1986-06-18
Abstract: PURPOSE:To achieve a higher accuracy of an end point method, by a method wherein an object to be measured is made to react with a reaction reagent to preset a time range in which the object being measured gives stable reaction data and a statistic processing is performed about a plurality of data obtained within the time range. CONSTITUTION:Curves 1 and 3 indicate actually measured data. When the data between the points M and N is outside an allowable error range epsilon due to bubbles and foreign matters attached at a portion following a point P the data between the points P and N is corrected to obtain a correction data as shown by a curve 2. The data between the points M and N is outside the allowable error epsilon only at a point Q, the data only at this one point is corrected to obtain a correction data as shown by a curve 4. In this manner, a measured data is corrected when considered as subjected to a long-term disturbance such as caused under the influence of bubbles in the range previously specified by M and N. Then, an approximate straight line is determined by the least square method to obtain the most probable value at the final point N as specified from the approximate straight line thus obtained.

Abstract: PURPOSE: To remove organic matters in a BPSG film or a PSG film without giving adverse effect on the electrical characteristics of a semiconductor device by depositing an insulating film by using an organic-based source gas on a semiconductor substrate and thereafter performing a heat treatment under partial pressure of oxygen in a particular numerical range.

Title: Lead-acid battery
Inventor: OKAMOTO HIROSHI
IPC: H01M4/74
Filed: 1993-05-19
Abstract: PURPOSE:To provide a lead-acid battery capable of notifying the life end while avoiding a trouble by electrolyte shortage by limiting the intersection sectional areas of an expand network body successively small from the upper stage of the grid body. CONSTITUTION:After the long-term use of an expand network grid 1, the intersection parts 3 of the network skeleton are rapidly corroded in a highly concentrated diluted sulfuric acid by the reduction in level lower limit, and the superiority depends on the intersection area 4 of the sectional area seen from the direction vertical to the grid part plane of the part where the skeletons are duplicated in the intersection part. Thus, a grid in which the intersection area 4 is successively reduced from the upper stage of the grid body 1 is provided, whereby the intersection in the lower part is first corroded and broken in an electrolyte prior to the intersection in the upper part to lower the battery function while continuing it, so that a feeling of deterioration can be given to a user. Since the breakage is started from the lower part where the electrolyte is difficult to be short, a spark by rupture is difficult to cause, and safety is enhanced.

Title: Striker engaging fixture
Inventor: TANAKA SEIJI
IPC: F16B21/07
Filed: 1982-08-19
Abstract: PURPOSE:To ensure smooth and tight engaging motion of a damping part with a striker by providing guide piece having a low friction coefficient at the striker sliding part of the recess in the damping member. CONSTITUTION:When a striker S is squeezed into a striker locking fixture K, the striker S is struck to guide pieces 10 which cover the upper lower and internal faces of a recess 6 and is then guided into the recess 6, while sliding on the guide pieces 10. Since the guide pieces 10 have a lower friction coefficient than that of the striker S, frictional resistance which is produced at the contact part between the striker S and the guide pieces 10 may be extremely low so that the striker S is guided by the guide pieces 10 and smoothly travels to be toward the inside of recess 6 tightly locked there. Clearances 18 are provided between the guide pieces 10 and the holder 4, on account of which the damping member, 5 may be subjected to elastic deformation as much as the clearance 18 at the moment of strike, hence moderating the impact force.

Title: Manufacture of secondary battery negative electrode
Inventor: AKAGI RYUICHI
IPC: H01M10/0565
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To reduce the contact resistance between a current collector and a sintered body in a negative electrode containing silicon as active material by baking a coating film containing silicon and a base material consisting of a conductive metal foil or mesh. SOLUTION: To manufacture a secondary battery negative electrode, a binder and a solvent are added to a negative electrode material containing silicon to prepare a slurry. The slurry is then applied to a base material consisting of a conductive metal foil or mesh, and the solvent is removed to produce a coating film. The coating film is integrated into the base material and sintered by baking under non-oxidizing atmosphere. Since the contact area of the interface between the sintered body and the current collector is increased to integrate them together by baking under non-oxidizing atmosphere, the contact resistance between the sintered body and the current collector can be reduced, and a negative electrode consisting of a thin film improved in conductivity can be provided.
