Title: Image forming system
Inventor: SUZUKI YOSHIYUKI
IPC: H04N1/405
Filed: 1986-11-14
Abstract: PURPOSE:To control the diameter of an abjective picture element by controlling the luminous quantity and laser emitting time based on the relation between the objective picture element and its adjacent picture elements. CONSTITUTION:When the objective picture element 'X' is included neither in an edge nor in a thin line, analog switches 113, 114 are turned off, the luminous flux quantity of laser is L1 and a converting curve gamma1 of the ROM 102 of a pulse width modulation is selected and a conventional state is attained. On the other hand, when the objective picture element 'X' is included in the edge or thin line in parallel with the scanning direction of the laser, the analog switches 113, 114 are turned on and the luminous quantity of laser is small as L3. Thus, in case of the image scanning system, the thick black thin line and the thinned white thin line in parallel with the laser scanning direction is compensated. In the background scan system, the thicked white thin line and the thinned black thin line in parallel with the laser scanning direction are compensated efficiently.

Title: Ambient air detecting apparatus
Inventor: MANAKA JUNJI
IPC: G01J1/02
Filed: 1994-11-02
Abstract: PURPOSE: To prevent gases and water from adhering to an ambient air sensor and precisely detect the ambient air in the environment by heating the ambient air sensor at low temperature by applying small electric current at normal time. CONSTITUTION: Small current is applied to an atmospheric sensor to carry out heat radiation at as low temperature as about 100 deg.C, so that adhesion of gases and water to the atmospheric sensor which sometimes causes a detection error can be prevented. Detection of ambient temperature is carried out during the low temperature heating period and detection of the atmosphere is carried out during the time when the atmospheric sensor is heated to high temperature. In this ways, heating to high temperature can be done only by increasing the intensity of the current to be applied to the atmospheric sensor.  In the case, for example, 2mA current is for the time of low temperature heating and 8mA current for the time of high temperature heating, a rated current power source with 6mA should be prepared and detection can be carried out only by turning the rated current power source on or off. Consequently, not like a conventional one, a switching circuit is made no need and a pause period in which gases and water adheres to the atmospheric sensor can be shortened. As a result, the atmosphere in the environment can be detected precisely.

Abstract: PROBLEM TO BE SOLVED: To fix a heat insulating plate with ease and provide a flat surface without difference in the level by fixing heat insulating plates to a concrete surface and making a nearly I-like joint member intervene in the joint section of the heat insulating plate. SOLUTION: A heat insulating plate 20 is formed in such a way that the front side is made flat and the back side is provided with water introducing grooves 21, which vertically and horizontally cross each other at a specified interval. In the next step, the heat insulating plates are arranged on the floor face 1b of the concrete surface 1 connected to each other through a joint member 30 and are fixed through fixing nails 4. This joint member 30 is formed of a long member with nearly I-like cross sections, which is composed of the upper and lower base section and perpendicular sections. The water introducing grooves 21 on the back face prevent the generation of high back pressure in the heat insulating plate 20.  Due to the nearly I-like shape of its cross section, durability is maintained against both of the pressures applied from the front and back sides of the heat insulating plate 20. This constitution prevent back pressure from applying to the insulating plate 20 even if ground water leaks, preventing heat insulating performance from lowering.

Title: Current direction detecting method for higher harmonic in distribution line
Inventor: ITO KATSUJI
IPC: G01R29/00
Filed: 1992-10-09
Abstract: PURPOSE:To provide a method for detecting the direction of current of higher harmonic flowing through a distribution line easily. CONSTITUTION:A capacitor Caa (or capacitors Caa, Cab, Cac) is connected in parallel with a section of predetermined length of distribution line and a series circuit of a switch SW11 and a capacitor Cb is connected between two lines on the side closer to power supply or load than the joint of the capacitor Caa. Capacitance of the capacitor Caa (or capacitors Caa, Cab, Cac) is then regulated to form a parallel resonance circuit, along with the inductance L of the distribution line, for the higher harmonic current flowing through the distribution line. The switch SW11 is then closed and the higher harmonic current of phase A is detected on the side closer to power supply or load than the joint of a capacitor Cb. Since higher harmonic current, flowing in from power supply side or load side, can be blocked by means of the parallel resonance circuit, direction of higher hatmonic current can be detected upon detection of presence of higher harmonic current.
