Title: Enclosed type lead storage battery
Inventor: YONEZU KUNIO
IPC: H01M2/12
Filed: 1984-03-30
Abstract: PURPOSE:To miniaturize the captioned lead storage battery with higher reliability by forming an exhaust part into a structure having a non-porous plastic sheet with small holes disposed in close contact with both sides of a porous sheet. CONSTITUTION:When the interior of a lead storage battery is pressurized with non-porous plastic sheets 3 and 2 respectively directed toward the inside of the battery, gas in the battery is discharged from a small hole 3' via the interior of a porous sheet 1 and from a small hole 2'. In contrast with this, when the interior of the battery is reduced in its pressure, the fresh air enters from the small hole 2' via the inside of the porous sheet 1 and from the small hole 3'. A gas permeation speed is increased with the areas of the small holes 2', 3' much more increased. The gas permeation speed in the porous sheet 1 is more reduced the thinner the thickness and the longer the distance between the small holes 2' and 3'. Accordingly, areas of the small holes 2' and 3', the distance therebetween, and the thickness of the porous sheet 1 are combined to provide optimum values whereby the gas permeation speed is set to the optimum value. In addition, with the porous sheet 1 being water-repellent, even if acidic mist produced in the battery sticks thereto, holes of the porous sheet 1 is not blocked and thereby the gas permeation speed can be kept constant.

Inventor: ISHII KAORU
IPC: B23K33/00
Filed: 1982-04-20
Abstract: PURPOSE:To perform double-side butt welding without entry of air in the regular welded bead, by grooving the root part of the groove on the side opposite from the side where materials to be welded are tack welded by a sealing bead, etc. then performing regular welding. CONSTITUTION:A sealing bead (tack welding bead) 3 is formed in the part of the groove 2 on the lower side of materials 1, 1a to be welded, whereafter a groove 7 wider several times than a root 4 is formed by means of a jig 10 such as a circular saw over the entire part of the root 4 from the groove 2a side, in the case of double side butt welding. The part of the groove 2a and the groove 7 is then subjected to regular (arc) welding. The air in the groove 7 is easily expelled by an inert gas in the stage of regular welding and the formation of a blow hole in the regular welded bead 5 is obviated. It is effective to groove only the part having a level difference particularly when the level difference is produced in the part of the grooves 2, 2a.

Filed: 1984-03-30
Abstract: PURPOSE:To attain more sure air-tight sealing by forming a sealing face of an opening of a box type package to a lower side and taking the reference plane as the sealing plane so as to ensure the flatness of the sealing face. CONSTITUTION:In the manufacture of the box type package 11, the sealing plane 15 of the opening is formed to the lower side conversely as a conventional method where a raw material such as glass is flowed into the die. In this case, since the sealing face 15 is taken as a reference, the flatness of the sealing plane is kept in an excellent way. Thus, in putting a piezoelectric vibrator into the package and covering the sealing face, since the flatness of the sealing face is ensured, the air-tight sealing is attained. Dotted lines in Fig. show the case that a little raw material is given and a pool 65 is provided when much raw material is used. In both the cases, there is no problem in covering a cover and air-tight sealing and the flatness of the sealing face is ensured.

Title: Colorimetry sensor device
Inventor: SAKAI SHINJI
IPC: G01J5/10
Filed: 1984-03-30
Abstract: PURPOSE:To convert a signal into a digital signal by giving an offset to an output of a colorimetry sensor so as to allow each colorimetry sensor to be brought into a prescribed level range thereby using a simple A/D converter. CONSTITUTION:The light current flowing to a colorimetry sensor 4 comprising R and B sensors is fed selectively to a log amplifier section 5 comprising a decoding section 1 and a switch section 3, subject to logarithmic compression and amplified, outputted by a final amplifier section 6. Input terminals A, B of a selection input terminal 2 are controlled by an output of a system controller 13 and the output of the R and B sensors or a constant current is outputted to a Vout depending on the values of the A, B. Since plural stages of offset adjustment are conducted by a final amplifier 6, the dynamic range is widened remarkably. That is, even if the Vout is out of the range of permissible input 0.3-3V of an A/D converter 11, the range is restored within 0.3-3V by giving an offset voltage.

Title: Screen control system
Inventor: OBATA AKIHIKO
IPC: G06F3/0481
Filed: 1987-03-19
Abstract: PURPOSE:To simplify the addition of applications as well as the change of the screen constitution by performing a series of processes via the message communication carried out between objects by means of a pointer. CONSTITUTION:There is no module controlling an entire screen, and the coordinates are analyzed by a cooperative action of patterns (objects serving as modules respectively) on a display. Each object has its own procedure as well as its own state and starts an application via the message communication carried out between objects. In such a case, the state of each object includes the pointers to its own coordinate position as well as to its related objects. In such a way, the state of the screen of each object is controlled by itself and therefore the screen constitution can be easily changed just with the local comprehension of the constitution.

Output signals Q1-Q3 of the counter 70 are decoded at an analog multiplexer 90, and an analog switch is sequentially turned on from the most significant digit of a meter switch 80 every circulation of the above advancement, to read out numerals of each digit. Since a current flows to a transistor TR1 which is turned on according to the numerals read out, the transmission end potential of the collecting station drops. Quick and accurate data can be transmitted by monitoring this potential drop at the collecting station.

Filed: 1991-03-28
Abstract: PURPOSE:To enhance reliability in start control of motor and to realize downsizing and noise suppression. CONSTITUTION:Upon turn ON of power, AC current is fed to the main winding (L1) of a motor (10). The AC current is rectified through a bridge rectifying circuit (BG) and a thyristor (SCR) is turned ON according to the rectified output and thereby a triac (TR) is turned ON to feed an AC current to an auxiliary winding (L2). At the same time, a capacitor (Cc) in a time constant circuit (TC) is charged according to the rectified output from the bridge rectifying circuit (BG). When the potential of the capacitor (Cc) reaches a predetermined level, a transistor (Q1) is turned ON and thereby the thyristor (SCR) is turned OFF while the triac (TR) is turned OFF. Consequently, current flowing through the auxiliary winding (L2) is interrupted thus finishing the starting operation.
