Title: Continuous casting method of ingot
Inventor: EKIMORI TERUMICHI
IPC: B22D11/128
Filed: 1981-12-30
Abstract: PURPOSE:To eliminate thoroughly the bulging strain of an initially cast ingot by applying positive driving force upon upper stream side rolls, applying negative driving force reverse to the direction where the ingot is drawn and guided upon lower stream side rolls and dispersing the driving force to plural rolls. CONSTITUTION:When the preceding end of an ingot arrives at driving rolls 21 via walking bars 4, negative driving force (braking force) is applied upon said rolls so that an initially cast ingot is begun to be applied with compressive force. Thereafter, braking forces are applied upon the driving rolls 22-25 of the 2nd group successively at every arriving of the preceding end of the ingot at said rolls and said forces are changed to positive driving in order of the rolls 21-24 through which the ingot passes or in succession, the braking forces are applied upon the rolls when the preceding end of the ingot arrives at the driving rolls 31 of the 3rd group. The braking upon the rolls 21 of the 2nd group is changed to the positive driving, and according to the progression of the preceding end of the ingot to the lower stream side, the driving rolls 32-35 of the 3rd groups are successively applied with the braking or the driving rolls of the 2nd group is changed over from the braking to the positive driving. By either of such changing, the working points of the compressive forces are moved from the upper stream to the down stream and to leveling points, whereby the compressive guiding of the initially cast ingot is completed.

Title: Sealed type lead-storage battery
Inventor: NAKAJIMA YUKIO
IPC: H01M50/121
Filed: 1985-09-25
Abstract: PURPOSE:To suppress the decreasing rate of water content in electrolytic solution by using an electrolytic tank made by injection molding of ABS resing to which mica is added. CONSTITUTION:An electrolytic tank made by injection molding of ABS resin to which for example, 40wt% of non-permeable mica of scale-like shape is added with the surfaces of the scale-like mica particles arranged to be parallel to the wall surface, is used. Because the mica is not permeable, water molecules going to pass the resin at right angles to the wall forming the electrolytic tank are prevented from going straight by the mica while being allowed to advance by roundabout routes. Therefore, travelling distance of the water molecules is increased, having the same effect as increasing the wall thickness, and the rate of permeation can be reduced and, in consequence, the decreasing rate of water can be suppressed to a low level.

Title: Method and device for measuring effective value
Inventor: SWIFT STEVEN D
IPC: G01R19/02
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To easily and accurately convert signals with a high crest factor which change with time to an effective value by processing input signals at the preceding stage of an effective value converter and determining the effective values of electric signals which change with time. SOLUTION: A measuring device 4 includes an amplifier 14, an ADC 16, a compensating circuit 18, an effective value conversion computer 20, and a display part 22. Input signals to be measured which change with time are amplified at the amplifier 14 of a non-linear transfer function, and the digital sample of its output is obtained at the ADC 16. Then the non-linear transfer function is compensated for at the compensator 18, and effective values are continuously obtained at the effective value converter 20. Therefore, by amplifying input signals which change with time by the non-linear transfer function, in other words, gain with a plurality of inclinations according to the amplitude of the input signals, it becomes possible to restrict the dynamic range of the effective value converter 20.  Therefore, even if the input signals are in a pulse shape with an especially high crest factor, it becomes possible to measure them easily and accurately.

Title: Disk reproducer
Inventor: OINUMA AKIRA
IPC: G11B27/34
Filed: 1981-12-26
Abstract: PURPOSE:To know simply the time elapsed or the residual time of a play for a reproducer of a constant linear speed system, by displaying the position of a pickup by means of a time axis of a disk play. CONSTITUTION:A disk 1 turns at a constant linear speed by a spindle motor 3 and produces a pulse signal 12 with the combination of a pulse disk 10 and a photointerrupter 11 and in response to the revolution of a feed screw 5 which shifts a pickup 4. The number of pulses produced at and after the track starting position of the disk 1 are counted integrally, and this count value is proportional to the radius position of the track. With a digital signal, the motor 3 is controlled so as to obtain a constant level for the relative linear speed between the pickup 4 and the disk 1. At the same time, the digital signal is converted into a real play time by an arithmetic circuit and then displayed at a display. Therefore the present position of the pickup 4 shows the time elapsed after the play is started.

Title: Image recorder
Inventor: NAGASHIMA KANJI
IPC: G02B26/10
Filed: 1989-08-18
Abstract: PURPOSE:To suppress unevenness in tint or color and irregularities in density by a method wherein a dot pitch in the direction of feed is determined to be 1/3n (mm/dot) or less independent of a dot pitch in the direction of main scan ning when the number of reflecting surface of a rotating polyhedron is (n). CONSTITUTION:In an image recorder 10, a dot pitch in the direction of feed is determined to be 1/3n (mm/dot) or less independent of a dot pitch in the direction, of main scanning, where (n) is the number of reflecting surfaces of a polygon mirror 16. Therefore, it is preferable that a beam spot on a recording material 40 is shaped to have a diameter in the main-scanning direction larger than a diameter in the feed direction. In this manner, unevenness in tint or color and irregularities in density caused by, e.g., an error of a reflectance of the polygon mirror attributed to a difference of a wave length of an optical beam are not visually conspicuous or recognized, even if occurred. An image with a good gray balance improved in color balance and density balance can be recorded all over the surface.
