Title: Digital signal processing system
Inventor: PIITAA CHIYAARUZU IISUTEI
IPC: G10L19/00
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To prevent an S/N from being lowered due to incorrect subtraction of a noise from a quantized signal. SOLUTION: At a device for quantizing an input digital signal after adding a digital noise, an index signal is encoded into an output digital stream by changing the probability for a prescribed bit of the output digital signal to become '1' or '0' corresponding to the current state of an index signal showing the addition of dither noise. The index signal is decoded by detecting whether '1' or '0' exist a little more in data. Thus, the same dither noise can be exactly subtracted from the quantized signal.

Title: Molding of optical element
Inventor: NEGISHI HIROAKI
IPC: C03B23/22
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To provide a method for molding an optical element moderated in the concentration of inner stresses, preventing the generation of a heat bank, and capable of transferring a highly precise molding surface free from the generation of cracks by molding the optical element in specific conditions, when thermally softened glass elements are press-molded by a prescribed method. SOLUTION: A method for press-molding a desired optical element by carrying a thermally softened glass element for molding the optical element between a pair of molds 1, 2. Therein, plural glass elements 3, 4 comprising the same glass materials and used for molding the optical element are separately heated (e.g. the element 3 is heated with a heater 7, and the element 4 is heated with a heater 8), laminated to each other and subsequently press-molded with a pair of molds 1, 2. Namely, a heat bank is usually formed in the center of the molded product, when a glass element material is heated and subsequently press-molded with upper and lower molds into a convex lens. When the glass element 3 and the glass element 4 are superposed on each other and simultaneously pressed, the interfaces of the glass elements are however melted and eliminated to reduce the generation of a heat bank.

Title: Amplifying circuit
Inventor: SUZUKI TAKEFUMI
IPC: H02J1/00
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To prevent the breakdown of switching transistor and transistor of pre-driver and to permit stable amplifying operation, by forcibly turning ON the switching transistor when supply of a first power supply voltage or a second power supply voltage of a power supply circuit is suspended. SOLUTION: When a fuse blows due to the short circuit of a load and a low voltage VccL is no longer supplied, a cathode of a diode D4 is pulled toward a minus potential by a higher voltage -VccH irrespective of H, L levels of a control terminal. Therefore, a base current is supplied to the base of a transistor Q5 from GND via a diode D5 and the emitter of the transistor Q5 is forcibly pulled up to a minus voltage. Therefore, the transistor Q5 and a power transistor M1 turn ON to operate the transistors Q1, Q2 in order to prevent breakdown of the pre-driver transistor QA. Since the cathode of zener diode ZD2 is grounded, it can be protected in stable even if the high voltage -VccH varies.

Title: Anti-skid control unit
Inventor: MATSUDA TOSHIROU
IPC: B60T8/70
Filed: 1983-11-17
Abstract: PURPOSE:To correctly perform the next braking even if a target wheel speed is not attained by prohibiting a slip ratio signal and deciding a liquid pressure control mode based on only the wheel acceleration/deceleration when a preset acceleration is attained in response to the relatively high acceleration on a high-mu road surface. CONSTITUTION:When a wheel speed reaches a target wheel speed, a comparator 7 generates a slip ratio signal, operates an AV valve 13, and switches to a pressure reduction mode. A relatively large acceleration is attained on a high-mu road surface, and when this acceleration reaches a preset acceleration/deceleration a2, the output of the comparator 25 is made H, then when the acceleration/deceleration becomes lower than the preset acceleration/deceleration a2, the output of the comparator 25 is decreased to L. In response to this decrease, a one-shot multivibrator 26 prohibits a pulse and resets a flipflop 26. Thereby, an AND gate 18 is made a prohibit state and the slip ratio signal of the comparator 7 is blocked, thus the control is switched to that based on only the wheel acceleration/deceleration. Accordingly, the next cycle control can be correctly performed even if the wheel speed does not reach the target wheel speed.

By inserting a catch bar 5 between the closed 2-ply band films T, T and by fretting holding the film tip end part T1 with the catch bar 5, an object to be bound can be wound and bound easily and surely. The band film T is made of a single layer film blending or a jointly extruded film of a linear chain low density polyethylene and a metallocene polyethylene, which makes it possible to heat seal at a low temperature in a short time and to obtain stable binding.

Abstract: PURPOSE:To suppress formation of an inactive lead sulfate layer and increase standing performance after discharge by controlling amount of electrolyte so  that no free electrolyte exists and regulating electrolyte concentration so that it  keeps 10% or more when distance finished. CONSTITUTION:A paste-like active mass comprising PbO and water is pressed to a grid comprising lead-calcium alloy to form each of a cathode and an anode.
