Title: Image forming device
Inventor: FURUKAWA TOSHIRO
IPC: G03G15/10
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To make maintainable the liquid repellency of a developer holding means having many minute holes for holding liquid developer such as mesh, etc., over a long term by providing a means for applying substance inferior in wettability to the liquid developer and having the liquid repellency or lyophobic property. SOLUTION: A scraper 7 is provided on a downstream side in a rotating direction from a position where the liquid developer 4 is supplied by a developer supply roller 5. In a state where the tip part of the scraper 7 comes into contact with the surface of a developer holding roller 3, the roller 3 is rotated and the amount of the liquid developer 4 on the roller 3 is adjusted to proper amount by the scraper 7. Besides, the scraper 7 itself is formed of silicone rubber or silicone resin, so that the surface of the roller 3 is coated with the silicone oil by performing scraping actions, and then the surface of the roller 3 always achieves the liquid repellency. Thus, the fine image is prevented from being painted out.

Title: Backfilling method for buried pipe
Inventor: NASU TAKU
IPC: E02B9/06
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To provide a simple backfilling method in which a pipe can be stabilized even when the ground is displaced by taking into account a displacement of the ground due to an earthquake when the pipe is buried so that damage to the buried pipe can be reduced. SOLUTION: A shock absorbing layer 12 is formed in a trench at a horizontal position in a direction normal to the axis of a pipe. The layer 12 has a compressive rigidity smaller than that of the ground 1 and has a vertical thickness equal to or less than the diameter of a buried pipe 3, and hence even when the ground is displaced in the transverse direction of a buried pipe 3, the layer 12 is compressed and deformed to absorb the displacement of the ground and even when the layer is compressed to its limit so that the layer loses its displacement absorbing ability and is rigidified, an influence on the pipe 3 can be maintained as much as the influence on an ordinary backfilling material 2 only.

Title: Exposure controlling method for color picture enlarger
Inventor: URYU TAKESHI
IPC: G03B27/73
Filed: 1989-03-08
Abstract: PURPOSE:To duplicate a color image with depth by keeping cyan filter density constant with respect to both a reference original image and an target original image. CONSTITUTION:The density of a cyan color filter 8C is kept constant with respect to both the reference original image and the target original image. To cope with an unbalance between colors occurring in the duplicated color image in order not to apply correction of the density of the cyanic filter 8C, the correction value for the density of the cyan color filter 8C, which is omitted from the correction value of the density of the cyan color value of the densities of yellow and magenta color filters 8Y and 8M, is subtracted. Consequently the suitable color balance can be obtained by using the subtracted value as the density of color filters 8Y and 8M. A high-quality color image with depth can thus be duplicated.

Inventor: OKUBO HISAKAZU
IPC: G03G15/16
Filed: 1994-03-24
Abstract: PURPOSE:To prevent the local concentration of stress on a transfer material carrying sheet and prolong the life of a recording material carrying sheet when repeated deformations are applied by forming a pressing member into a rotor made of an elastic body. CONSTITUTION:A roller center shaft 12a and a roller barrel section 12b are integrally formed by adhesion, and they are rotatably supported on a separating arm 20. The roller barrel section 12b is made of an elastic body such as a polyurethane foam body. When a pressing roller 12 is moved and a transfer sheet 6 is deformed, the pressing roller 12 is applied with the tension load of the transfer sheet 6 and deformed. The end sections of the pressing roller 12 are easily deformed, the center section is hardly deformed, thus the end sections of the pressing roller 12 are deformed after the transfer sheet 6 while the deformed quantity of the transfer sheet 6 required for separation is maintained. Large stress is not concentrated on the transfer sheet 6 at the end sections. The stress distribution occurring on the transfer sheet 6 can be nearly unified in the deforming action conducted for separation.

Abstract: PURPOSE:To avoid firing, smoking and smelling caused by an overcurrent by a method wherein a fuse composed of the narrowed part an electric source wiring is provided in the electric source wiring in a semiconductor chip. CONSTITUTION:A fuse 12 composed of the narrowed part of an electric source wiring 11 is provided in the electric source wiring 11 in the semiconductor chip of a semiconductor device whose bonding wires are molded in a range. As relatively large heat is generated in a very small portion when an overcurrent is applied to the wiring, the temperature of the fuse 12 reaches the melting point and the fuse is fused without fail. With this constitution, firing smoking and smelling caused by the overcurrent can be avoided.

Title: Disk reproducing device
Inventor: ARAMAKI JUNICHI
IPC: G11B19/06
Filed: 1991-02-26
Abstract: PURPOSE:To know the set time of a disk by producing a warning if an unloaded state or a reproduction mode of the disk is detected at the set time. CONSTITUTION:A timer mode is selected with operation of a key of a key operating part 10 end then a desired time or period is set. Thus the corresponding signal is supplied to a CPU 9 and the timer mode is set based on this signal. At the same time, the date on the desired time or period are stored in an internal memory (not shown in the diagram) of the CPU 9. Under such conditions, the CPU 9 supplies a display signal corresponding to the key operation to a display part 11 and the prescribed display is carried out. Then the CPU 9 starts the measurement of time and searches a focus at the set time to decide the presence or absence of a loaded disk 1. Based on this searching result, the CPU 9 decides whether an optical disk 1 is kept in a reproduction mode or not and whether the disk 1 is loaded or not. Then a warning tone is produced by a buzzer 14 under the due conditions.

IPC: F24F7/10
Filed: 1978-05-04
Abstract: PURPOSE: To prevent the abnormal run of a driving motor for a ventilating fan, by opening an energizing circuit for the motor after a prescribed time when an air pressure type shutter of a ventilator does not open.  
     CONSTITUTION: A knob 21 is operated so that the energizing circuit for the driving motor 6 is closed through a power switch 22 and a thermistor 25. When the driving motor 6 does not rotate, namely, the ventilating fan does not rotate because of the damage of an auxiliary coil of the driving motor 6 or the like and when the air pressure type shutter does not open due to a trouble, a shutter switch 13 is not opened by the shutter 12. As a result, the thermistor 25 of positive characteristic shows a high resistance and substantially opens the energizing circuit for the driving circuit motor 6 to prevent its abnormal run. The opening of the energizing circuit is indicated by lighting on an alarm lamp.
