Title: Processing method for silver halide color photographic sensitive material
Inventor: KAWAMURA TOMONORI
IPC: G03C1/035
Filed: 1989-11-10
Abstract: PURPOSE:To prevent the generation of unequal magenta in the color developing part in the case of use of a high silver chloride emulsion by processing the photosensitive material with a processing liquid having bleaching power within the specific time after color development processing. CONSTITUTION:The photosensitive material subjected to imagewise exposing is processed with the processing liquid having the bleaching power in succession to the color development processing. The photosensitive material has the silver halide emulsion layers contg. the silver halide particles substantially consisting of the silver chloride. After this photosensitive material is immersed into the processing liquid having the bleaching power, the emulsion surface of the photosensitive material is subjected to forcible liquid stirring within 30 seconds. The forcible liquid stirring refers to not the ordinary convectional flow of the liquid, i.e. the liquid circulating by, for example, a pump, but the forcible stirring by adding a stirring means. Thus, the generation of the magenta in the color developing part is prevented.

Abstract: PURPOSE:To simultaneously perform pulse motor driving processing by software and other processing by utilizing a time for performing the other processing by making a delay time variable corresponding to input data and including the other processing requiring a time longer than the min. pitch of said delay time. CONSTITUTION:It is investigated whether the number of copy papers are set by a number-of-copy paper setting means 11 and, when the number of copy papers are set, the number of copy papers are increased by one copy paper to be displayed on a display means 12 and delay of 500musec is performed. In the processing of the number of copy papers, a processing time of 500musec is constant regardless of the setting of the number of copy papers. That is, the cycle of the drive pulse of a pulse motor 7 is delayed by delay processing and number-of-copy paper processing of the processing time of 500musec is included within this delay processing. Therefore, the cycle of the drive pulse of the pulse motor 7 is not changed even if the number-of-copy paper processing is performed and the number-of-copy paper processing can be performed at least once per 500musec. As mentioned above, the driving control of the pulse motor and the number-of-copy paper processing exert no effect on each other and other processing can be performed simultaneously.

Title: Detector for battery deterioration
Inventor: MIYAZAKI SADAO
IPC: H01M10/48
Filed: 1988-11-21
Abstract: PURPOSE:To properly detect the deterioration of a battery by detecting a resistor temperature and turning off a battery charger and a switch when a detecting pulse circuit is out of order or a transistor is fractured. CONSTITUTION:A control circuit 32 turns off a battery charger 11 and turns on a magnet switch 12, thereby outputting a detecting pulse to a transistor 30. When the detecting pulse circuit and the transistor 30 are not out of order, a detecting pulse is properly outputted and the transistor 30 is turned on. Consequently, a voltage detecting circuit 31 detects voltage and the deterioration of a battery 13 is thereby detected. On the other hand, when the detecting pulse circuit or the transistor 30 is out of order at the time when the circuit 32 turns off the battery charger 11 ad turns on the switch 12, the detecting pulse and the transistor 30 remain turned on. When the temperature of a resistor 29 rises and a switch 33 is turned on, a relay 36 is energized and a light emitting diode 41 lights. As a result, an alarm signal is outputted and the switch 12 is turned off. Furthermore, a switch 33 is turned on and a transistor 17 is turned off, thereby turning off the battery charger 11.

Abstract: PURPOSE: To smoothen a forming work by forming while removing water drips in an air vent caused by dew condensation or preventing the freezing thereof by suitable means of air jetting, etc., at the time of forming at a low temp. CONSTITUTION: At the time of forming the blank cooled with cooling medium in a forming die 1, to the air vents 15 arranged in an upper and a lower dies 3, 5, the air is jetted from an air supplying source 25 through the piping 23 and an air pipe 19, or the air supplying source 21 is changed to a sucking device to suck the air in the air vent 15, and then, while removing the water drip in the air vent 15, the formation is executed. In the case of air-jetting, the warm dry air is desirably used, but since the jetting to the blank under a low temp. condition is not desirable, the jetting is executed in the interval after completing the formation, at which the upper die 3 reaches the lower dead center, and just before charging the following new blank into the lower die 5.  Further, in the case of air-sucking, it is desirable to avoid the generation of negative pressure at the time of taking out the formed produce from a lower die 5 after completing the formation.

Abstract: PURPOSE:To improve adhesion to rails in a wet condition by mounting a laser generating device for radiating at least one of the surface of the rails and the tread of each wheel on a vehicle and drying and cleaning the surface of the rails. CONSTITUTION:A laser generating device 4 is installed under the floor of a vehicle body 2 and its radiating port 5 is placed so as to radiate the surface of rails in front in the advancing direction of the vehicle. During the traveling of vehicle, e.g., at the time of rainfall, the laser generating device 4 is operated radiating laser 6 out of the radiating port 5 onto the rail surface, thereby momentarily drying up the rail surface to increase the adhesion coefficient between wheels 3 and rails 1 up to the value at the time of drying. Due to the radiation of the laser, not only water but also oil and other dirty material can be removed from the rail surface cleaning the rail surface. Hence, the slip of the wheels 3, etc., can be suppressed producing a large effect in improving vehicle performance.
