Title: Sealed lead-acid battery
Inventor: YOSHINAKA MINORU
IPC: H01M50/528
Filed: 1987-04-08
Abstract: PURPOSE:To make battery structure simple and to make a battery small and lightweight by forming a recess in the central part between cells of a connector, and applying acid resistant oil to the recess. CONSTITUTION:A recess 10 is formed in the middle part of a connector 5 which connects between cells, and oil 9 having high viscosity is applied to the recess.

Title: Measuring device
Inventor: ARUFUREETO ATSUFUA
IPC: G01D5/245
Filed: 1984-05-01
Abstract: A measuring system for measuring the relative position of tool machine parts compensates for thermally-induced length changes of a spindle stock by means of a scale carrier which acts as an expansion element for a scale. This scale carrier is fastened at one end directly via a fastening element to the spindle stock and at the other end is connected with an adjacent end of the scale, which is mounted on the scale carrier so as to be shiftable in the measuring direction. If the plane of the tool connected to the spindle stock shifts by an amount  DELTA c in the measuring direction X as a result of temperature rises of the spindle stock, the scale carrier, operating as an expansion element, acts to pivot a rotatable element having an adjustable lever ratio in order to shift the scale in the same direction. In this way, the entire thermally-conditioned displacement of the scale is also made to equal the amount  DELTA c.

Title: Distance measuring apparatus
Inventor: SHIOMI YASUHIKO
IPC: G03B13/36
Filed: 1984-04-28
Abstract: PURPOSE:To prevent the lowering in distance measuring accuracy due to the effect of noise, by applying photoelectric conversion to the pulse light reflected from an object by a light receiving element and detecting the level of the DC component during output to connect a DC signal control circuit when the detected level is equal to or more than a predetermined value. CONSTITUTION:The pulse signal reflected from a subject is received by a semiconductor position detection apparatus PSD. PSD is biased by a power source Bat and forms a current I corresponding to the quantity of incident light when light is incident to a light receiving surface and signal currents IA, IB (wherein IA+IB=I) are outputted as position signals by a pair of electrodes. When the distance between the electrodes A, B of PSD is set to L and the distance from A to a light receiving point of (x), relations of formulae I, II is formed and the distance (x) is calculated from the relation of the signal currents IA, IB. When a DC signal control circuit not shown in the drawing is added so as to control I= IA+IB constantly, the current IA or IB is allowed to correspond to the distance (x) to calculate a distance. By this method, precise distance measurement can be performed without being obstructed by noise.

Title: Hue control circuit
Inventor: TANAKA SADAAKI
IPC: H04N9/45
Filed: 1980-06-26
Abstract: PURPOSE:To control the hue of a chrominance signal on the carrier wave with simple constitution by supplying two 90 deg. out-of-phase input chrominance signals to two variable gain circuits and by adding the outputs of those variable gain circuits together. CONSTITUTION:An input chrominance signal is supplied to a balanced modulator 1, and another chrominance signal shifted in phase via a 90 deg. phase-shifting circuit 7 is supplied to a balanced modulator 2. Then, the outputs of the modulators 1 and 2 are supplied to and added together by an adding circuit 8, thereby obtaining a hue-controlled output carrier from an output terminal 9. To control phase shifts of the modulators 1 and 2 with this circuit constitution, a gain control signal generating circuit 5 generates a gain control signal (a) varying linearly and a gain control signal (b') varying in an arc shape under the control of a potentiometer 12 and then supplies them to the circuits 1 and 2 respectively. Thus, the hue of the chrominance signal on the carrier wave is controlled over a 0-180 deg. range.
