Title: Alkaline battery
Inventor: AZUMA HACHIROU
IPC: H01M4/42
Filed: 1983-09-07
Abstract: PURPOSE:To improve weighing accuracy and stabilize the performance of an alkaline battery by preparing a negative agent from zinc powder containing at least 90wt% of spherical zinc particles having a mesh of 100-200 and a longer axis diameter/shorter axis diameter ratio of 1.1 or below. CONSTITUTION:Zinc powder containing at least 90wt% of zinc particles of 100- 200 mesh manufactured by a rotary drum method and having a longer axis diameter/shorter axis diameter ratio of 1.1 or below, is amalgamated with 10pts. wt. (to 100pts.wt. of the above zinc powder) of mercury to prepare a negative agent. Next, after a negative electrode 7 is formed by the negative agent, the negative electrode 7 is combined with a positive electrode 1, a separator 3, an electrolyte-absorbing body 4 and the like, thereby constituting a button-type silver oxide battery. As a result, weighing accuracy can be widely improved due to an improved fluidity of the negative agent achieved by restricting the form of the zinc particles. Consequently, it is possible to sufficiently cope with a decreased size of the battery and to stabilize the discharge performance of the battery.

Title: Vacuum collet
Inventor: TANIZAKI AKINORI
IPC: B25B11/00
Filed: 1982-09-22
Abstract: PURPOSE:To obtain the vacuum collet enabled to prevent an IC from receiving damage by a method wherein holes are pored at the notch parts of the four corners of the tip edges of the vacuum collet, and a shock absorbing material having elasticity is filled up in the holes thereof. CONSTITUTION:The four corners of the tip edges 20 of the vacuum collet are notched, the holes 21 are formed thereat, and silicon rubber 22, for example, is filled up in the holes 21 thereof as the shock absorbing material having elasticity. The IC chip 1 comes in contact with silicon rubber 22 only with the four corner parts thereof, and the four edges of the IC chip 1 never come in contact with the inside wall 11 of the vacuum collet. Accordingly, when tearing off of the IC chip from an adhesive tape 2 and equipment in a concave part 7 are to be performed, the IC chip comes in contact with silicon rubber 22 with any of the four corners thereof at first. At this time, because silicon rubber 22 has sufficient elasticity, damage at the four corners is avoided. Moreover, because none of the four edges of the IC chip comes in contact with the inside wall 11 of the vacuum collet, the four edges of the IC chip never receive damage, and even when the IC chip 1 is equipped in the recess part 7 of the vacuum collet in any condition, damage of the IC chip can be avoided.

IPC: G11B11/10
Filed: 1984-08-08
Abstract: PURPOSE:To improve a reproduced SN ratio by making the 1st light flux modulated to polarized status in accordance with information magnetically recorded on a recording medium interfere with the 2nd light flux having frequency different from that of the 1st light flux and detecting the information as the strength change of the interference light. CONSTITUTION:Light flux 11a radiated from a laser light source is divided into light flux 11b having P polarization and light flux 11d having S polarization. The light flux 11b is transmitted through a beam splitter 13 and converged upon a recording medium 15. The reflected light modulated by the medium 15 is reflected by the splitter 13 and transmitted through a beam splitter 18 as light flux 11c including both P and S polarization. On the other hand, the light flux 11d having the S polarization and reflected by a splitter 12 is made incident upon a frequency shifter 16 and frequency-deviated light flux 11e is reflected by a relector 17 and the splitter 18 and made to interfere with the light flux 11c on the basis of light mixing. The light flux 11f to be the interference light is turned to light flux 11b including only the S polarization through a detector 19 and detected through a condenser 20. Thus, the S/N ratio can be improved and reading can be attained.

Abstract: PURPOSE: To shorten the manufacturing process of a self-aligned transistor by forming a polysilicon layer on a base area and diffusing an impurity in the base area from the polysilicon layer after injecting the impurity into part of the polysilicon layer. CONSTITUTION: A polysilicon layer 20 is formed on a base area 18 so that the layer 20 can cover the entire surface of the area 18 and an oxide layer 30 is only grown on the part of the layer 20 exposed together with an eroded part immediately below a nitride side-wall area 28. Then the layer 20 is etched while the layer 20 is masked with the remaining part of a dielectric layer 22 and the oxide layer 30. After the layer 20 is etched, an emitter connecting section 34 and two base connecting sections 36 are formed by removing the dielectric layer 22 and oxide layer 30 by performing selective etching against silicon. The emitter connecting section 34 contains an N<-> -type impurity due to implanted arsenic and the base connecting sections 36 contain such a P-type impurity implanted into the sections 36 in the form of ions.  Therefore, both self-aligned emitter and base areas can be formed through one time of polysilicon layer treating process.

Filed: 1979-12-21
Abstract: PURPOSE:To make the video signal binary stably, by setting always the level of the background part of the signal output from the operating means to a constant value and by comparing the output signal of the operating means and a proper threshold level with each other. CONSTITUTION:Inversion sample holding circuit 3 outputs signal (r) when low- level sample hold instructing signal (q) is applied. Operational amplifier OP4 adds and amplifies output signal (r) of circuit 3 and video signal (n) to output signal (s). Since output signal (r) of circuit 3 has the same absolute value as the level of the background part of video signal (n) and has the sign opposite to that of this level, the level of the background part of signal (s) output from amplifier OP4 is zero. Even if the ambient temperature is changed to change DC components of video signal (n), the level of the background part of signal (s) output from amplifier OP4 is zero.

IPC: H01M10/60
Filed: 1984-08-09
Abstract: PURPOSE:To prevent the life of a storage battery from becoming short by reducing the pressure applied to the electrode group due to the expansion of the container caused by the temperature increase of the battery by causing a coolant to flow through the spaces of each partition wall which extend from the top to the bottom of the container. CONSTITUTION:Each of the thick partition walls 6 of a storage battery has spaces 7 extending from the top of the container 1 to its bottom. The top and the bottom of the container are provided with parts 9 each of which has one opening end 8 and the inner sides of which are continuous with the spaces 7 to form a path for air or water which is made to flow in the direction indicated by the arrow thereby cooling the storage battery. Owing to the above structure, it is possible to suppress the increase in the temperature of a large-capacity storage battery having a monoblock container which is caused either when the battery is used in a place with high atmospheric temperature or when the battery is charged or discharged with a high current level. Accordingly, the pressure applied to the electrode group due to the expansion of the container is reduced, thereby preventing the life of the battery from becoming short.
