Title: Corona charger
Inventor: KOMATSU TORU
IPC: H01T19/04
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To obtain a corona charger for which peak discharge electrodes are used so as to eliminate the adverse influence of ozone generation by holding ozone decomposing materials in an electrode supporting body. SOLUTION: An aluminum sheet having, for example, 1mm thickness is used for a holding plate 31 as an electrode plate 3. Electrode members 32 are formed by etching only on one surface of the holding plat 31 in such a manner that the peaks of the plural peak discharge electrodes 32a line up at a pitch of 2mm on a straight line existing in the position retreating by, for example, 0.5mm from the front end of the holding plate 31. For example, AgO is used for the ozone cracking materials. The ozone cracking members 33 which are fixed only to the surface of the holding plate 31 not formed with the electrode members 32 are used. As a result, corona discharge is generated by the peak discharge electrodes 32a and, therefore, the ozone generation is lessened. Since the generated ozone is cracked by the ozone decomposing members 33, the problems by the generation of the ozone are eliminated.

Title: File management system
Inventor: NAKATSUCHI YOSHIMASA
IPC: G06F12/00
Filed: 1990-11-14
Abstract: PURPOSE:To efficiently access a record and to prevent the useless security of resources by allocating a long time to a file with high using frequency and automatically opening a file with low using frequency in accordance with the contents of data. CONSTITUTION:An access file management part 5 inspects the using frequency of an instantaneously accessible file based upon information stored in an access file using state instructing part 12. A data processing procedure part 2 opens allocation to a file whose using frequency is less than a previously set level and the opened file name is deleted from the instructing part 12. On the other hand, allocation to a file whose using frequency is higher than the previously set level is continued as it is and only the instructing part 12 is initialized. Consequently, the execution of useless resource allocation can be prevented.

Title: Switching regulator controlling ic
Inventor: SHINGU KAZUHIRO
IPC: H02M3/28
Filed: 1987-12-04
Abstract: PURPOSE:To detect a period of time during which an overcurrent limitation works, by using a D-type FF receiving outputs of SRFF and PWM comparator, and a transistor which is turned ON and OFF by the output of the D-type FF. CONSTITUTION:When an output signal D of SRFF 4 is on a low level at the time of falling of an output signal E of a PWM comparator 7, an output signal G of a D-type FF 22 also is on a low level and causes the charging of a monitoring time setting capacitor 28 with a constant current from a constant current power source 24 through a transistor 25. After the charging is conducted for a certain period of time and the voltage of a terminal 27 reaches a reference voltage 29, an output signal I from a comparator 30 is transferred to a high level so that a latching circuit 31 operates and its output becomes a signal J. After that, when the overcurrent state is over, the signal G shifts to a high level to return to the initial state. In this manner, it is possible to decrease the numbers of external parts and the terminals of a switching regulator controlling IC.

Title: Snow-melting system
Inventor: MORIOKA HIROSHI
IPC: E01H5/10
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To supply hot water to sprinkling pipes when outside air temperature is low and it snows so as to provide the required snow melting functions by combining a heater which supplies hot water to the sprinkling pipes with a controller. SOLUTION: A number of sprinkling pipes P having nozzles specified intervals are installed on the surface G of the ground where snow melting is required. A snowfall sensor 21 is installed outdoors, and when it snows the sensor outputs a snowfall signal S1. A temperature sensor 22 is also installed outdoors to measure outside air temperature K. In addition, a temperature is set by a setter, along with a reference temperature at which snow accumulates, and a comparison circuit determines whether or not the heater operates. If the snowfall signal S1 is issued and the outside air temperature K is lower than the set temperature, a control signal S7 is fed to the heater 14 to cause the sprinkling pipes P to sprinkle hot water to melt the snow.  When the outside air temperature K is high, the signal for operating the heater is not fed, but a control signal S6 is fed so that a pump 12 and a switching valve are actuated to open to melt the snow with water.

Title: Charge adjustment machine of parking lot
Inventor: SATO NORIMASA
IPC: G06Q30/04
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To surely issue a service ticket to a parking lot user by issuing the service ticket recording the service contents for the user according to parking time at the time of a charge adjustment. SOLUTION: At the time of the adjustment of parking charge, a CPU 21 performs a judgement as to whether a service ticket is issued or not. This judgement is performed by depending on whether parking lot using time is more than the time necessary for issuing the service ticket or not. When the time is more than the necessary time, the issue of the service ticket is judged. In the case of the issue of the service ticket, the service contents according to the parking time that a receipt issuing part 27 already calculates is magnetically printed on a parking charge receipt by a printer 29, the receipt which is also used as the service ticket is issued with the dropping of change via a receiving port. Thus, the charge adjustment of the parking lot user is terminated.  If the user who receives the receipt which is also used as the service ticket uses the receipt as the service ticket when the user uses the partking lot next time and performs a charge adjustment, the user can use the parking lot for nothing or at the lower price than normal parking charge.

IPC: B29C44/00
Filed: 1993-11-16
Abstract: PURPOSE:To simplify construction work, to give prescribed water retention properties to earth and sand on a surface and to make it possible to maintain the water retention properties for a long period by a method wherein the rate of the number of gap parts of specified maximum diameters is made a prescribed value or above to the total number of gap parts in the section of a foamed molded body. CONSTITUTION:When the maximum diameter of a gap part 3 is made L in a foamed molded body 1 which is formed by joining a plurality of foamed chips 2 together and has the gap parts 3 communicating with one another, the rate of the number of the gap parts 3 of which L is 2mm through 10mm is made 0.9 or above to the total number of the gap parts 3 of which L is 2mm or above. Thereby the flow of water through the molded body 1 is made gentle, the possibility that sand sprinkled on the molded body 1 is let to flow with the water through the gap parts 3 communicating with one another is eliminated and also a force drawing the sand into the molded body 1 is made small. Since the water permeates at a moderate velocity through the molded body 1 and is discharged outside the foamed bodies 2, moreover, regulation of water permeability in the range of a minute quantity is enabled and the permeability can be controlled so that the sand on the molded body 1 may not be dried.

Inventor: JIEIMUZU II UIRIAMUZU
IPC: G03G13/01
Filed: 1990-11-15
Abstract: PURPOSE: To use the same development system to form a 3-level image highlighted by color and a 2-level black image by performing switching between the standard DC mode and the chopper type DC bias mode. CONSTITUTION: In the 3-level highlight color mode, rolls 35 to 38 are alternately biased to a high-level voltage VBias and a low-level voltage VBias through bias power sources 41 and 45 for CDC bias. In the monochromatic black print mode, a conventional DC bias is given to rolls 37 and 38 through a switch 49 by a standard bias power source 43. The latitude of exposure for operation in the 3-level highlight color mode is extended by switching from the DC bias to a black developer housing to a chopper type DC bias. Thus, a black copy with high quality is obtained, and a 3-level image highlighted by color is formed.

When no voltage is applied, incident light is diffracted at the time of incidence and of incidence on the diffraction grating again after passing the lambda/4 plate 4 for two times, and no light scattering and advancing in the forward direction is generated, then, a non-display state is generated, thereby, display with high visibility can be obtained.
