Title: Image pickup device
Inventor: OKINO TADASHI
IPC: G03B15/05
Filed: 1984-12-10
Abstract: PURPOSE:To distinguish the correct image pickup due to gain increase and that due to only flash light emission from each other and to report them to a photographing person by displaying the gain increase due to a gain increasing means and the dimming confirmation, which is attained when the quantity of light of an image surface reaches a correct value, in display modes different from each other. CONSTITUTION:The output of a photometric circuit A of a flash light emitting device is sent to a light emission stop circuit from a terminal P2. A window comparator B arranged in a control part is set to the operatable state when power is supplied tothe comparator B from a terminal P3. A variable gain increasing device C increases the gain of an input image signal from a terminal P4. If the exposure is sufficient by flash light emission, an indicator 17 is lit by the output of a comparator 12 to display the dimming confirmation. If a picture can be obtained by the increase of the gain is spite of underexposure, the output of the comparator B goes to the high level because the comparator B is so set that its output is in the high level only when the charging voltage of an integral capacitor 2 is between voltages V2-V4, and an indicator 16 is lit to display the increase of the gain. The voltage V2 indicates an allowable limit value of the exposure with which photographing is possible without increasing the gain, and the voltage V4 indicates that of the exposure with which photographing is possible by the increase of the gain.

Title: Toner residual detecting device
Inventor: TORISAWA AKIRA
IPC: G03G15/00
Filed: 1990-10-01
Abstract: PURPOSE:To detect the exchanging time of a developing device by comparing a signal value from a storage means with a signal value about toner residual in the developing device from a detection means through a comparison means. CONSTITUTION:When a new process cartridge 8 having different kind of toner is loaded in the device main body of an image forming device, an ID number is inputted and stored in a 2nd memory 25 from a microcomputer 30. At a stage where an image is formed by the cartridge 8, an initial current value which flows in an electrode 21 for detection from a developing roller 3b is converted into a voltage value through a conversion means 22 and stored in a storage area corresponding to the ID number in a 1st memory 24. The value of a ratio between a voltage value based on the initial current value and the voltage value transmitted through the electrode 21 and the means 22 from moment to moment is compared and examined by a comparison and decision means 23. When the value of the ratio attains a specified value, a warning signal is outputted to an exchanging display means 26. Thus, a developing device 3 is surely exchanged.

Title: Multiplex transmission speed data communication system
Inventor: MAEKAWA EIJI
IPC: H04L12/40
Filed: 1988-10-18
Abstract: PURPOSE:To allow plural pieces of sub-equipment to efficiently communicate through a common transmission path with main equipment by possessing a device to supervise a signal on a common outgoing transmission line and a device to control the sending of the signal to a common incoming transmission line by means of the sub-equipment, and automonously judging the propriety of communication. CONSTITUTION:Sub-equipment 2 to have a transmission speed different from that of the signal on a common outgoing transmission line 11 as the inherent transmission speed does not send a detecting signal from a signal detecting part 13, and since it does not sends a coincident signal from a speed conicidency detecting part 19, it does not transmits the signal to a common incoming transmission line 12, and the signals at the different transmission speeds do not collide on the line 12. Further, when the signal exists on the line 11 and the transmission speed of the signal corresponds to the transmission speed of the self-sub- equipment, the sub-equipment 2 sends the detecting signal from its detecting part 13, and since the consistent signal is sent from a detecting part 19, the equipment 2 can sends the signal onto the line 12, and the communication at the same speed is attained in the common transmission line. The propriety of the communication through the transmission line can be autonomously judged by the equipment 2 by sending a transmission stop signal 21 from a signal transmission control part B 20 to a main circuit part 16 by the device 2.

IPC: B42D15/10
Filed: 1993-10-19
Abstract: PURPOSE:To prevent the occurrence of cracking and obtain the excellent close adhesion with a substrate and high flexbility by washing the surface opposite to the grooved surface of a transparent substrate with a soln. prepared by diluting a hard coat soln. to a specific value and applying the hard coat soln. to the washed surface in such a state that a very small amt. of the diluted soln. is left on the washed surface and optically curing the same to form a hard coat layer. CONSTITUTION:The surface opposite to the grooved surface of a transparent substrate is washed with a diluted soln. 7 of 10-100ppm prepared by diluting a hard coat soln. consisting of a transparent photo-setting hard coat main agent and a solvent with the same solvent to set such a state that a very small amt. of the diluted soln. 7 is left. Next, a hard coat agent 8 is applied to the washed surface to be irradiated with light 9. At that time, since photo-setting is started in such a state that the interface of the transparent substrate 1 and a hard coat layer 2 is rich in the solvent as compared with the surface of the hard coat layer 2, the hardness of the hard coat layer 2 after curing becomes gradient in the thickness direction. In the photo-setting process, the interface of the diluted soln. 7 and the hard coat agent 8 is eliminated to form the hard coat layer 2.

IPC: E02D3/12
Filed: 1993-09-24
Abstract: PURPOSE:To heighten durability of packer rubber and to improve adhesion by adhering a check valve simply by way of attaching a check valve system on an injection pipe, arranging a packer device in the check valve device and sliding the packer rubber. CONSTITUTION:Inside of an injection pipe 1, a check valve device 2 is installed. When a ground improving material is injected in a drilled hole 5 and pushed out to a space 24 for a check valve from a hole 22 for the check valve, a check valve rubber 23 is opened. When the ground improving material is pushed out from the space 24 for the check valve to the hole 22 for the check valve, the check valve rubber is closed and back-flow is prevented. Thereafter, a double packer device 3 installed with an inner pipe 31 and an outer pipe 32 is arranged in the pipe 1. When a jack 4 is operated, both of the pipes 31 and 32 slide, and rubber 36 slides to a protruded part of a first cylinder 33. In the same way, rubber 37 slides to a protruded part of a second cylinder 34. Thereafter, the first and second packer rubber 36, 37 are adhered inside of the check valve. Consequently, it is possible to lessen liquid leakage of the ground improving material and to heighten injection pressure.
