Title: Method for cleaning blade of electrophotographic copying machine
Inventor: IIDA HARUKI
IPC: G03G21/10
Filed: 1983-08-03
Abstract: PURPOSE:To prevent a photosensitive body from damage due to the pressing force to a blade by charging the photosensitive drum before the formation of an image on the photosensitive body, making the photosensitive body adsorb toner passing through a blade part, discharging the photosensitive body to reduce the surface potential of the photosensitive body, cleaning the photosensitive body with a brush to make the photosensitive body execute a series of operation. CONSTITUTION:A main charger 4 is actuated, the photosensitive body 1 is rotated in the arrow direction by starting a main motor, and when toner 3' passed through the blade 2 and adhered to the surface of the photosensitive drum passes the main charger 4, voltage almost equal to normal charging voltage is applied to the toner 3'. When the photosensitive body 1 is irradiated by an erasing lamp 5, the part adsorbing the toner 3' is kept at the absorbing status as it is, so that the toner 3' passes without being adhered to a seal member 8 and the most of toner 3' is removed by a developing brush of a developing device 7. Immediately after the removal of the toner, normal copying operation starts. The residual toner 3' without being removed by the developing brush is cleaned by the actuated blade 2.

Title: Label, manufacture of label and plastic vessel with label
Inventor: FURUSAWA NOBUO
IPC: B29C45/14
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To enable simultaneous sticking of a label with formation of a plastic vessel irrespective of the quality of the vessel subjected to adhesion, by a method wherein a sealant layer is constituted of linear-chain low-density polyethylene and surface treatment is applied at least to the surface of the sealant layer which is subjected to the adhesion. SOLUTION: A sealant layer of a label is formed of linear-chain low-density polyethylene and surface treatment is applied at least to the surface of the sealant layer to be subjected to adhesion. As for the linear-chain low-density polyethylene, linear-chain low-density polyethylene synthesized by such a catalyst of a single site series as represented by a metallocene catalyst, for instance, is used. Accordingly, an oxide layer is formed on the surface of a linear-chain low-density polyethylene film in the case when the surface thereof is subjected to corona discharge treatment or by exposing it to ozone gas under the condition of high-temperature melting. An oxide of this oxide layer or an active oxidation seed acts effectively and a large strength of adhesion to a plastic vessel is obtained. Thereby the label can be stuck simultaneously with formation of the vessel.

Title: System and method for compacting data by buffer control
Inventor: CHIYAARUSU ESU UEEBUAA
IPC: G06F5/00
Filed: 1989-06-07
Abstract: PURPOSE: To prevent buffer overflow and underflow by increasing or reducing the truncation of a digital sample signal according to the increment or decrement of fullness respectively. CONSTITUTION: As the fullness of a transmitting buffer 36 increases more, the truncation of an input to a digital compressing filter 28 is increased more, and an average encoder output bit rate is reduced below the bit rate of the channel so as to reduce the fullness of the buffer 36. Also, when the fullness of the buffer 36 reduces below a prescribed threshold level, a means which changes the operation of a variable word length encoder 30 is given so that it may operate with out of range(OOR) operation mode independently of the range of a supplied input signal. Thus, the bit rate to the buffer 36 is increased. Thereby, the overflow of the buffer 36 is eliminated and also the underflow of the buffer 36 is avoided.

Abstract: PURPOSE:To increase the size of a spraying nozzle and to facilitate the adjustment of a spacing between nozzle terminals so that mass production is enabled by communicating plural pressure equalizing chambers provided in the flow passages, on the upper stream side of the spraying nozzle, for a liquid spraying medium for atomizing and cooling a molten metal flow by means of plural pipes. CONSTITUTION:This device is constituted of outside and inside nozzle cylinders 6a, 7a respectively provided with the nozzle terminals 1a, 2a, an upper plate 8 of the pressure equalizing chamber and a cylinder 9 of the pressure equalizing chamber and is internally constituted of the 1st and 2nd pressure equalizing chambers 3, 4 and the plural communicating pipes 5 communicating these chambers, etc. Since the pressure equalizing chamber 3 can be formed relatively small, the liquid pressure to be impressed between the nozzle terminals can be minimized. The influence by the liquid pressure impressed on the wall surfaces of the chamber 3 and another pressure equalizing chamber 4 is not received between the nozzle terminals and, therefore, the adjustment of the spacing between the nozzle terminals is easy. Furthermore, a sufficient volume can be provided to the chamber 4 and the uniform pressure obtd. in the chamber 4 can be introduced into the chamber 3 without largely changing the same. The desired purpose is thus attained.

Title: Adjusting device for resonance frequency of resonance type oscillation detector
Inventor: TAKEUCHI KIYOSHI
IPC: G01H13/00
Filed: 1980-10-16
Abstract: PURPOSE:To sorten the time required for adjusting operation by cutting the oscillator of a detector intermittently and by detecting the frequency of free oscillations of the oscillator while a cutter is separated from the oscillator. CONSTITUTION:A sub-assembler 2 is fixed on a fixed table and while a resonance frequency is measured by a frequency measuring instrument 15, the diaphragm composed of a piezoelectric body 28 and a mtallic body 29 is cut with a rotary grindstone 16. This grindstone 16 has a projection part 16a at some part of its circumfrenece, and the projection part 16a cuts the diaphragm intermittently. When this projection part 16a is separated from the diaphragm 26, the waveform of free oscillation is a sine wave and the frequency corresponds to the resonance frequency of the diaphragm. Therefore, the frequency of the free oscillations is read by a measuring instrument 15 from the output of the sub-assembler 2 to find the resonance frequency of the diaphragm. Thus, while cutting operation for adjusting the resonance frequency is performed, the frequency of the free oscillation is measured to facilitate adjusting operation,thereby shortening the time required for the adjusting operation.

Abstract: PROBLEM TO BE SOLVED: To monitor the alarm of a repeater in a fire alarm system even in the case of disconnection accident by providing a cascade circuit for directly outputting the input of a main track when a branch circuit is normal and outputting it through an alarm circuit in the case of abnormality. SOLUTION: At normal time, a fire alarm system 1 does not invert the polarities of main tracks L1 and C1 and opens a relay rf1. In the case of accident such as a branch circuit 10b is disconnected, the fire alarm system 1 inverts the polarities of the main tracks L1 and C1 after the repeater, where the disconnection occurs, so that a terminator 30 is turned into non-conduction. Therefore, a receiver can detect the disconnection in the fire alarm system 1 by detecting non-conduction of the main tracks L1 and C1. Besides, even when a fire occurs at the time of such disconnection fault, the relay rf1 is closed and the main tracks L1 and C1 are short-circuitted so that the receiver can detect the fire in a residential ward, where the fire alarm system 1 is installed, by detecting short-circuitting of the main tracks L1 and C1.
