Title: Steel sheet having fine appearance after coating and superior pressability
Inventor: KURIMOTO MIKIO
IPC: C25D5/26
Filed: 1987-12-02
Abstract: PURPOSE:To obtain a steel sheet having fine appearance after coating and superior pressability by arranging many recesses each having specified dimensions and a flat bottom in the smooth surface of a steel sheet at regular proper intervals. CONSTITUTION:Recesses each having 2-7mum depth, 20-200mum diameter and a flat bottom are arranged in at least one side of a steel sheet at regular intervals. The interval between the adjacent recesses is made 1/3-3 times the diameter of the recesses and the surface roughness Ra of the smooth part is regulated to <=0.2mum. The recesses may be formed by projectingly patterning a work roll for temper rolling by etching or laser beam machining and by transferring the pattern to the steel sheet as a recessed pattern. The recesses are desirably arranged in a checkered or zigzag state. A coating film may be formed on the steel sheet by surface treatment such as electroplating, chromating or chemical treatment.

Title: Hot-water supplier
Inventor: MARUYAMA HIROKI
IPC: F24H1/10
Filed: 1992-10-16
Abstract: PURPOSE:To obtain hot-water of a desired temperature immediately upon dis charging hot-water again, permit the prompt rise-up of a hot-water temperature and prevent the generation of overshoot. CONSTITUTION:When the temperature TH of hot-water in a hot-water discharging passage 3a is low, a condition switching means 9 switches the operating condition of the supplier into forced accelerating condition, in which a heating amount FOUT is increased to the composite amount of a specific correcting amount dF and a necessary combustion amount F. When the temperature TH of hot-water in the hot-water discharging passage 3a is risen, a mixing control unit 6 chokes the flow rate of hot-water and increases the flow rate of water. When a hot-water temperature in the hot-water discharging passage 3a is increased sufficiently in such a control, the condition switching means 9 switches the operation into balanced condition wherein the amount of heating FOUT is the necessary amount of combustion F.

A 1st bias power terminal 18 is connected to a connecting point between a 1st termination resistor 7 and a 1st capacitor 13 via an inductance 28, a 1st resistor 29 and an inductance 27, and a 2nd bias power supply terminal 17 is connected to a connecting point between a 2nd termination resistor 6 and one end of a 2nd capacitor 12 via an inductance 26, a 2nd resistor 30 and an inductance 25. Since the resistors 29, 30 are inserted in the series resonance circuit in such a way, the Q of the resonance circuit is deceased to relax a sudden change in the input and output impedance. Thus, the band characteristic is improved.

Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To remove a reception signal inputted to a transmission system and to evade oscillation by providing a limitter in a reception system so as to use an amplitude comparing circuit in the transmission system. SOLUTION: Light inputted to a photodiode 30 is optic/electric-converted and inputted to a reception signal processing part 40. It is amplified by an amplifier 41 and amplitude-limited by the limitter in a reception signal processing part 40. On the other hand, a signal inputted from a synthesizing part 50 is compared in the comparing circuit 22 and outputted to a driving circuit 21 when amplitude is more than a set value and LED 10 is driven. The unrequired reception signal which is inputted to a transmission signal processing part 20 by way of the synthesizing part 50 is removed by providing the limitter 42 and the amplitude comparing circuit 22 so that the relative interference of the reception system with the transmission system is reduced.  Thus, transmission-reception signal is transmitted with one line but oscillation is not executed and favorable transmission-reception is executed.

Abstract: PURPOSE:To automatically take out a blow container one at a time in order to pack the same with a liquid by fixing a container support member capable of supporting the lowermost blow container so as to be covered therewith to the upper surface of a lift stand inclined with respect to a horizontal surface. CONSTITUTION:Separation pawls 9A, 9B capable of separating the uppermost blow container from other containers X are fixed to the upper part of a magazine main body 8. Each blow container magazine 6 has a lift stand 10 positioned in the magazine main body 8 to receive the received blow containers X and a container support member 11 is fixed to the lift stand 10 and supports a large number of the blow containers X so as to be covered therewith. Since the position of the center of gravity of the blow containers held to a folded state is made eccentric in such a state that the neck parts x1 of the blow containers X are retracted and a large number of blow containers X can not be set an orderly stacked state on the horizontal lift stand 10, the lift stand is inclined by an angle theta with respect to a horizontal plane. In this case, the angle theta is set to about 20 deg., however, when said angle theta is within a range of 10-35 deg., the same purpose can be achieved.

Title: Diesel cycle engine using differential drive supercharger
Inventor: KANESAKA HIROSHI
IPC: F02B39/06
Filed: 1991-09-09
Abstract: PURPOSE:To restrict the maximum combustion pressure within an allowable range so as to improve reliability interposing a rotary valve in the intake passage of an engine, while providing a supercharger pressure sensor, so as to substantial regulate a compression ratio according to the supercharger pressure. CONSTITUTION:When drive load is increased driving torque transmitted to a supercharger 10 by a differential gear mechanism 2 is also increased in proportion thereto. Supercharger pressure generated by a supercharger 10 is increased and the maximum combustion pressure becomes excessive, but the high supercharger pressure detected by a supercharger pressure sensor 17 is immediately transmitted to an actuator 16. Consequently, a regulation lever is moved by the actuator 16, and the closing time of a rotary valve 12 is quickened, and the maximum combustion pressure is decreased by closing it during an intake stroke. Consequently, torque at the time of low speed operation of an engine for a vehicle is enforced, and while conventional effect of differential drive supercharge is being maintained, reliability of the engine by using the differential drive supercharger may be improved without damage of the engine caused by the maximum combustion pressure beyond a design value.
