Title: Circuit for detecting deterioration of electrolytic capacitor
Inventor: WATANABE JUN
IPC: H01G13/00
Filed: 1986-12-27
Abstract: PURPOSE:To enhance the reliability of a power source circuit, by providing a low-band filter circuit for removing the high frequency noise contained in a detection voltage level to a comparing circuit performing the judgement of the deterioration state of a smoothing capacitor. CONSTITUTION:The voltage between the terminals of a smoothing capacitor 18 is taken out and the high frequency noise containing in said voltage is removed by a low-band filter circuit consisting of resistors R1, R2 and a capacitor C1. The ripple voltage thus obtained is set to a detection voltage level to be inputted to the negative side terminal of a comparator 28. The comparator 28 compares said detection voltage level with the reference voltage level inputted to the positive side terminal of said comparator 28 and outputs a high level output signal only for a period when the detection voltage level is lower than the reference voltage level. At this time, a predetermined width is generated at the operation point of the comparator 28 by the action of a histeresis resistor 7. Therefore, when the ripple voltage increases by the deterioration of the capacitor and becomes larger than the operation width of the comparator 28, the output signal of the comparator 28 is smoothed by an integration circuit consisting of a resistor R8 and a capacitor C3 and a comparator 44 or an alarm 46 is appropriately energized.

Abstract: PURPOSE:To reduce running costs for a railway snow-melting apparatus and to ensure insulation between two rails by a method wherein the snow-melting apparatus is constructed of heat sources heat-generating panels composed of insulating bodies, and pipes that induce heat medium liquid from the heat sources. CONSTITUTION:A railway snow-melting apparatus B is constructed of a plurality of heat sources 4, heat-generating panels 5... composed of insulating bodies and placed at intervals in pairs between sleepers 1, 1, and pipes 7, 7 that are placed in zigzag between the sleepers 1, 1 and are arranged for circulatory passage of heat medium liquid supplied from the heat sources 4 and for heating the heatgenerating panels 5, 5. Rails 3 and ballasts between the rails 3 are warmed by the heat-generating panels 5 and the pipes 7 that are heated up by circulation of the heat medium liquid. The heat medium liquid is then returned to the heat sources 4 for recycling after heat is radiated therefrom. Thereby, snow melting in a wide area extending over the rails 3 can be made, while insulation between the rails 3 is maintained so that normal functions of automatic signals and crossing gates can be ensured.

IPC: H04N1/40
Filed: 1990-11-15
Abstract: PURPOSE:To reduce the cost and to simplify the manufacture by using a dark correction circuit and a shading correction circuit whose hardware configuration is identical and forming a picture correction circuit not requiring a divider. CONSTITUTION:When a picture data Vi is inputted to a dark correction circuit 5, a subtractor 11 is used to calculate a difference Vi-Bi with a black reference data Bi stored in a line memory 13 for data correction and a transformation circuit 31 applies logarithmic transformation to send log(Vi-Bi) to a shading correction circuit 6, stored in a line memory 23 and used for a reference of shading correction. A subtractor 32 of the correction circuit 6 takes a difference between log(Vi-Bi) and log(Wi-Bi) and a transformation circuit 33 applies inverse logarithmic transformation to obtain (Vi-Bi)/(Wi-Bi) to apply shading correction. Since the dark correction circuit and the shading correction circuit are identical in terms of the hardware, the circuit is simply and inexpensively manufactured.

Title: Fluid pressure source device
Inventor: YAMADA TOMOJI
IPC: F04B49/06
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To ensure accumulator pressure even if a pressure switch is damaged by estimating and calculating a pressure reducing rate of a fluid pressure line while indicating high pressure by a pressure detecting signal of the pressure switch for detecting pressure of the fluid pressure line, and driving a fluid pump for a setting time when the pressure reducing rate exceeds a setting value. SOLUTION: When a normal pressure detecting signal is outputted by a pressure switch PH, accumulator pressure of an accumulator ACC received delivery pressure of a fluid pump HP is held to a setting pressure or more by a first pressure increment control means ECU. However, when a pressure detecting signal indicating low pressure is not generated by failure of the pressure switch PH, the number of applying of fluid pressure on a load such as a wheel cylinder is countered by a countering means ECU. When the number exceeds a setting value, the fluid pump HP is driven for a setting time by a second pressure increment control means ECU, and the counter value of the countering means ECU is reset. It is thus possible to ensure accumulator pressure suitably regardless of failure of the pressure switch PH.

Title: Production of paper for photographic printing paper
Inventor: KATSURA TORU
IPC: D21H21/04
Filed: 1990-11-15
Abstract: PURPOSE:To obtain paper for photographic printing paper having superior photographic properties and safety while controlling slime by adding a specified slime controlling agent to a cationic starch and an alkyl ketene dimer and then adding the resulting paste to paper stock. CONSTITUTION:Alkyltetrahydro-1,3,5-2H-thiazianine-2-thione as a slime controlling agent is added to cationic starch having <=5% concn. of solid matter and an alkyl ketene dimer and then the resulting paste is added to paper stock. The amt. of the cationic starch added is regulated to about 0.5-5.0wt.% of the amt. of solid matter in the paper stock. Since the slime controlling agent is previously added to the cationic starch as a principal nutrient for microorganisms instead of the conventional addition to paper stock, the slime controlling effect is enhanced. Paper for photographic printing paper having superior photographic properties and safety to the human body can be obtd. while controlling slime.
