Title: Gas discharge type light printing head
Inventor: TEROUCHI YUUJI
IPC: B41J2/447
Filed: 1988-02-05
Abstract: PURPOSE:To lessen emission start lag time with a small sized head, by a method wherein when discharge and emission are performed by impressing voltage to a printing anode and a printing cathode, auxiliary discharge is performed with a projection electrode and discharge start lag is controlled. CONSTITUTION:In a gas discharge type printing head wherein a printing cathode 12 and a printing anode formed by two substrate 11, 15 are opposed to each other via a discharging gas medium and light is emitted by impressing voltage, a projection electrode 18 is formed to the printing cathode 12 (or the anode 16) via an emission control film 13 to be positioned on the opposed printing anode 16 side. Then, when discharge and emission are performed by impressing voltage between both electrodes 12, 16, auxiliary discharge is performed with the projection electrode 18, and discharge start lag is controlled. Emission start lag time in an emission part can be thus decreased without arranging an auxiliary discharge electrode separately, and therefore, the head can be miniaturized.

Inventor: INOUE MASAYUKI
IPC: G03G15/00
Filed: 1987-02-04
Abstract: PURPOSE:To perform a compensation in accordance with the deterioration of a photosensitive body by estimating the deterioration of the photosensitive body based on the counted value of a counter corresponding to the quantity of prints and changing the potential difference between the photosensitive body and an electrostatic charger in accordance with this estimated deterioration. CONSTITUTION:The counted value of a counter 1 is counted up by one for every one print, and a signal control circuit 2 reads in the counted value from a terminal 22 and outputs a voltage corresponding to the counted value. A high-voltage constant current generating circuit 3 outputs a voltage proportional to the charging voltage from a terminal 34, and this voltage is inputted again from a terminal 33 through a resistance 6 to output the charging current while performing the feedback control. Since the output of the control circuit 2 is inputted to the high voltage constant current generating circuit 3 from the terminal 33 through a resistance 7, the current inputted to the terminal 33 is changed in accordance with the counted value of the counter 1 to change the charging voltage. Thus, the surface potential of the photosensitive body is kept constant with an inexpensive constitution.

Abstract: PURPOSE: To provide favourable buffer action in a frequency range in a broad band, especially for low frequency vibration by making a restriction by narrowing a communicating hole dimensionally set by forming it in a passage shape only in a range of a point limited narrow in the axial direction. CONSTITUTION: A channel cross-section 13 prepared in a direction of a working chamber 6 matches materially with a channel cross-section of a communicating hole 10. At the time when vibration is introduced to a support bearing 1, liquid exchange carried out between the communicating hole 10 and the working chamber 6 is never materially disturbed due to it. In the meantime, a restriction 12 formed restricted and non-flexibly limited is provided in an intermediate region between the other end of the communicating hole 10 and a compensating chamber 4, and its channel cross-section is made about 0.25-0.35 times as large as the channel cross-section of the communicating hole 10. Consequently, it is possible to provide another buffing effect by complementing buffing work based on a resonant effect, and excellent buffing efficiency is performed in an overall frequency range.  Additionally, it is possible to manufacture this bearing at low cost in comparatively simple constitution.

Title: Plate glass container
Inventor: FURUKAWA SHIGENOBU
IPC: B65D19/44
Filed: 1992-01-13
Abstract: PURPOSE:To reduce storage area by a method wherein a supporting member is provided to retain a pair of plate glass holding members at a predetermined inclination angle and the plate glass holding members are made foldable to a height lower than the place of folding main supporting members. CONSTITUTION:A pair of glass holding members 4 having a plurality of plate glass securely arranged in a stacked condition therebetween is retained stably by a supporting member 2 provided integrally with the rear side of the plate glass holding members. When the plate glass is stored in a plate glass container, the plate glass holding members 4 are both inclined by the supporting member 2 at a predetermined angle to the container bottom and, by such an inclination angle, the plate glass holding member 4 occupies a vertical plane space smaller than the vertical plane of the container. When the plate glass container is empty, the plate glass holding members 4 and main container supporting members 12a and 12b are folded to make the container lower as a whole. In this way the plate glass container can be reduced in the area required for storage.

Title: Resistor
Inventor: HIRAI TOSHIO
IPC: C23C16/30
Filed: 1989-02-02
Abstract: PURPOSE:To increase resistivity, and to reduce the temperature dependency of resistivity by using a composite material composed of boron carbide and conductive carbon as the material of a heating resistor employed for a thermal head, etc. CONSTITUTION:The electric resistance of a composite material, in which conductive carbon is dispersed into boron carbide in the magnitude of a molecular level through a chemical vapor deposition method, etc., is hardly influenced by a temperature though the relationship of the temperature of boron carbide and electric resistance displays a semiconductor-like behavior. A specific resistance value is made higher than that of interstitial type metallic nitride and carbide only by approximately one or three figures, and the length and size of a wiring and film thickness can be brought within the range of high reliability when the resistor is used as a thin-film resistor. Since the resistivity of a film has large temperature dependency when boron carbide is brought to 50mol% or more and oxidation resistance is deteriorated when boron carbide is less than 10mol% in the composite material consisting of boron carbide and carbon, it is proper that boron carbide is brought to 10-45mol%. The composition ratio of boron carbide and carbon is changed, thus arbitrarily setting the specific resistance value.
