Title: Hot water producing device
Inventor: FUJISATO KIMIHIKO
IPC: F24H1/00
Filed: 1993-11-25
Abstract: PURPOSE:To provide a hot water producing device which is constituted to increase an amount of hot water fed to a user and eliminate a fear of an excessive load being exerted on a pump device and reduce incurring of a heat loss. CONSTITUTION:Water in a tank 1 to which cold water C is fed is discharged by a pump device 4 and water delivered from the pump device 4 is recovered to the tank 1 through a circulation passage 5. A mixer 6 is arranged in a position situated downstream from the pump device 4 in the circulation passage 5. By inputting hot water to the mixer 6 and blowing steam S in an air bubble state in hot water, the temperature of hot water is increased. Hot water which is heated, is taken out of a user piping 12 branched from the circulation passage 5. A recovery pipe 14 arranged downward from a take-out part 5b of the user piping 12 of the circulation passage 5 has a flow passage narrower than other part of the circulation passage 5. This constitution suppresses a flow rate of hot water H recovered in the tank 1 and provides a sufficient amount of hot water fed to the user side.

Title: Waterproof/heat insulating board
Inventor: NISHIWAKI KOKICHI
IPC: B32B5/18
Filed: 1994-11-30
Abstract: PURPOSE: To provide a waterproof/heat insulating board provided with a waterproofing function and a heat insulating function as a single member, by integrally molding a skin layer in both surfaces of a foam layer having a closed cell. CONSTITUTION: In both surfaces of a foam layer 2 formed of hard polystyrene of 3000kg/cm<2> or more elastic coefficient to have 0.02 to 0.05 apparent specific gravity and a 5 to 10mm thick closed cell, a 100 to 200μm thick skin layer 3 is integrally molded to constitute a waterproof/heat insulating board 1. Here by setting plastic to that having a 5000 to 7000kg/cm<2> elastic coefficient, this waterproof/heat insulating board is made of so-called semihard or hard plastic. When the apparent specific gravity of the foam layer is less than 0.02, compression bending strength is decreased, and when the apparent specific gravity exceeds 0.05, heat conductivity is increased. When a thickness of the foam layer is less than 5 to 10mm, heat insulation is decreased.  By making the foam layer function as the heat insulating layer and the skin layer function as the waterproof layer, mechanical strength of the board can be particularly made excellent.

Title: Self-held delay solenoid
Inventor: HIDA ETSUJI
IPC: H01F7/16
Filed: 1987-12-21
Abstract: PURPOSE:To enable a plunger to be self-held in suction state at stroke end, by delaying working speed in either suction or anti-suction of the plunger. CONSTITUTION:During suction action of a plunger 3, a check valve 12 is released, and the air within a plunger sliding space A is immediately discharged from a large air hole 10 to the outside, and thereby the suction action of the plunger 3 is rapidly performed. On the other hand, during anti-suction action of the plunger 3, external air is introduced little by little from a small air hole 9 into the plunger sliding space A, and thereby return action of the plunger 3 is slowly performed. At this time, the check valve 12 is closed, and thereby passage of air through the large air hole 10 is blocked. When the plunger 3 reaches stroke end, even if current flow through a magnetic coil 2 is interrupted, both the plunger 3 and a fixed iron core 4 form a part of a magnetic path of a permanent magnet 16 in a body, and therefore this solenoid is self-held.

Title: Automatic printing selector device of printer
Inventor: TAGUCHI NORIYUKI
IPC: B41J2/315
Filed: 1987-12-18
Abstract: PURPOSE:To identify the type of paper at the time of start and remove an ink ribbon in the thermosensitive paper mode, while permitting the ink ribbon to exist automatically in the thermal transfer paper mode, by identifying whether or not print exists by means of a detection signal from a printing detector and controlling a printing operation and an electromagnet. CONSTITUTION:The existence of print is detected by a printing detector set nearby in a direction opposite to the advance of a thermal head 5, and if print is detected, the thermosensitive paper mode is selected as a result of decision to permit a subsubstrate 16-3 to rotate at a specified angle with the help of a spring-fitted hinge. In this way, an ink ribbon 4-1 is allowed to pass through paper 1 and the thermal head 5 to perform printing. If print is not detected, the thermal transfer paper mode is selected as a result of decision to return a carriage 16 to a start position according to the instruction of a control circuit. At the same time, an electromagnet 16-2 embedded in the carriage 16 is excited to attract an attraction plate and rotate the subsubstrate 16-3 to an arrow direction D. In this way, the substrate is caused to come into contact closely with a substrate 16-1 and the ink ribbon 4-1 is inserted between thermal transfer paper and the thermal head 5. In this state, the thermal transfer paper is printed by starting the device again.

Filed: 1988-12-22
Abstract: PURPOSE:To prevent the eccentricity of a photosensitive drum with respect to a driving shaft by interposing an elastic body positioning the photosensitive drum in the thrust direction between a positioning means, which is fitted to a drum driving shaft and is positioned in the thrust direction, and the photosenditive drum. CONSTITUTION:To position for photosensitive drum 6 in the thrust direction (s), the elastic body 8 interposed between the flange part 61 of the photosensitive drum 6 and an object 9 which is fitted to the drum shaft and is positioned in the thrust direction is pushed. In this case, a V-shaped groove 61a and a driving pin 7a are free in the thrust direction (s), whereas in the rotating direc tion (r) they are connected when the drum driving shaft 7 is driven. However, they have a clearance with some range. Consequently, even if the groove 61a and/or the driving pin 7a is out-of-center, an unnecessary stress does not arise between the driving pin 7a and the groove 61a. Thus, the eccentricity of the photosensitive drum with respect to the driving shaft can surely be prevented.
