Title: File control system
Inventor: TOMIYAMA TAKUJI
IPC: G06F12/00
Filed: 1987-09-08
Abstract: PURPOSE:To ease the deleting standard of files and to improve the operating performance of a user to files by controlling the writing/reading dates and the minimum number of days to be preserved from the end of the writing/ reading actions of data against the files. CONSTITUTION:When the writing/reading action of a file are carried out, a date updating means 6 writes the writing/reading date into a file control information storing part 2 and at the same time starts a file deleting means 9 every prescribed period. Then a comparison means 7 compares the writing/reading date with the number of days stored by a limit day number setting means 8. When the limit number of days pass over from the writing/reading date of the file, this file is deleted out of a large capacity storage device 1. As a result, even such a file that has the small reference value and small updated value is never deleted for improvement of its practical application as long as said file receives accesses every day.

Title: Light source device
Inventor: KURUMAYA HARUMICHI
IPC: G02B23/26
Filed: 1991-09-05
Abstract: PURPOSE:To reduce the size of a light source and reduce the heat diffusion by providing a concave mirror which guides the light from the light source forward and interposing a reflecting mirror between the concave mirror and a rod lens, and setting the angle of incidence on the rod lens to less than a critical angle. CONSTITUTION:The light from the spot light source 39 such as a halogen lamp is guided to the end part 42 of the rod lens 41 close to the light source 39. Further, the light from the light source 39 is reflected by the concave mirror 43 and guided to the end surface of the rod lens 41. The reflecting mirror is interposed between the concave mirror 43 and rod lens 41. This reflecting mirror is formed in a shape of a hollow frustum which is tapered so that the reflecting surface decreases in diameter toward the rod lens 41; and the light from the light source 39 and the light reflected by the concave mirror 43 are guided and made incident on the end surface 42 of the rod lens 41. In this case, the angle of incidence of the light on the end surface 42 of the rod lens 41 is selected below the critical angle of the rod lens 41, so the light is reflected totally in the rod lens 41 and transmitted with high efficiency.

IPC: F02B19/18
Filed: 1982-12-25
Abstract: PURPOSE:To reduce the throttle loss and heat loss, and consequently improve the fuel consumption and exhaust smoke by a structure wherein the exit angles of an auxiliary combustion chamber nozzle at the opening ends of a main combustion chamber side and of the auxiliary combustion chamber side are specified each other so as to form the precombustion chamber nozzle in a curved bore. CONSTITUTION:The exit angle theta2 made by the axis line of an auxiliary combustion chamber nozzle 3 at the opening end of an auxiliary combustion chamber 2 side is set at 90 deg. or less. The auxiliary combustion chamber nozzle 3 is formed in a curved bore so as to establish a relationship of theta1<theta2; where theta1 is the exit angle made by the axis line of the auxiliary combustion chamber nozzle 3 at the opening end of a main combustion chamber 1.

Title: Cooling device
Inventor: TANAKA KOJI
IPC: F25B1/00
Filed: 1987-09-10
Abstract: PURPOSE: To prevent an evaporator from being frozen even if the evaporator is being operated under a lack of gas by a method wherein a sensor for preventing a frozen state of the evaporator is fixed to a refrigerant inlet pipe passage of the evaporator. CONSTITUTION: A cooling cycle is formed such that a compressor 1 is operated and refrigerant discharged out of the compressor 1 flows in sequence from a condenser 2, a pressure reducing device 3 and an evaporator 4 and is returned back to the compressor 1, resulting in that a dwelling room 5 is cooled. When the saturation temperature of the refrigerant flowing in a refrigerant inlet side pipe passage 7 of the evaporator 4 is lowered to less than 0 deg.C during this cooling operation, this temperature is detected by a sensor 6, a freezing prevention signal is generated from a controller 8 and then a capability of the compressor 1 is reduced. Even under this situation, if the temperature is lowered below -1.5 deg.C, the operation of the compressor is stopped, the evaporating temperature of the evaporator 4 is increased to prevent freezing from being carried out.  As described above, there occurs a lack in the circulated amount of refrigerant applied for sensing a saturation temperature of condensed liquid refrigerant flowing into the evaporator 4. Even if the device is operated in a state of lack of gas, a freezing of the evaporator 4 is prevented.

Title: Phase correction system
Inventor: OGAWA TORU
IPC: H04L27/18
Filed: 1988-09-09
Abstract: PURPOSE:To reduce the time when data communication is disabled by allowing a master station MODEM to detect a phase deviation, informing it to an opposite MODEM and allowing an opposite MODEM to correct the phase deviation. CONSTITUTION:A controller 9 of the master station MODEM 2 identifies the opposite MODEM, a phase deviation detection circuit 11 detects the phase deviation of a signal wave sent from the slave station MODEM 6 via a private line 5 and the detected phase deviation is informed from a MODEM section 10 to the opposite MODEM. Upon the receipt of the notice of the phase deviation, the phase correction circuit 16 of the opposite MODEM corrects the phase deviation. Thus, the rewrite of the correction value of the line distortion is not required and the time when the data communication is disabled is reduced.

IPC: G01N30/62
Filed: 1990-08-29
Abstract: PURPOSE:To shorten the time until the concentration of the measured constituent is stabilized and improve the reliability of the analyzed value by confirming the stability of the concentration of the measured constituent at the time of calibration, and performing sampling many times if it is not stabilized. CONSTITUTION:If an adsorptive measured constituent is contained in an actual sample, the concentration C of the measured constituent is changed at the time of calibration. When the change quantity ( c/ t) of the concentration C per unit time exceeds a preset value (k), the analysis sequence is switched. The normal state is changed to the state with the increased sampling frequency, the device is operated fixed times, then the operation is resumed in the normal state. The action to check the necessity for the sequence switching based on the change quantity is repeated. When the change quantity becomes a preset value or below, the stationary operation is resumed in the normal state. The instability of the concentration C can be dissolved in a short time. When the stability of the sample concentration C is confirmed, the reliability of calibration is improved.

IPC: G03G15/02
Filed: 1984-10-30
Abstract: PURPOSE:To make ripples smaller while the rise responding speed of the surface potential of a photosensitive body is increased, by changing the responding speed of an inversional amplifier circuit in accordance with the difference between the output voltage of the inversional amplifier circuit and that of a reference power source. CONSTITUTION:A DC high-voltage power source 1 compares the output voltage of a reference power source 2 and that of an inversional amplifier circuit 3 with each other and, when the output voltage of the circuit 3 is a little higher than that of the power source 2, generates a lower high voltage. When the output voltage of the circuit 3 is much higher than that of the power source 2, the power source 1 generates a higher high voltage. A controller 7 compares the output voltage of the reference power source 2 and that of the inversional amplifier circuit 3 with each other and supplies such control signals to the inversional amplifier circuit 3 that delay the responding speed of the circuit 3 a little when the latter is a little higher than the former and increase the responding speed the latter is much higher than the former. In short, the controller 7 changes the responding speed of the inversional amplifier circuit 3 proportionally to the difference between the output voltage of the inversional amplifier circuit 3 that of a reference power source 2.
