Filed: 1979-09-25
Abstract: PURPOSE: To improve operating characteristic by so constituting the device that automatic focus controlling may be changed over to at least two modes, the 1st operation mode performing focus controlling only once at the first photographing and the 2nd operation mode of performing it continuously during the photographing period.  
     CONSTITUTION: When a change-over knob 12 is set at the FA position, an automatic focus control circuit 21 is set to a mode which performs automatic focus controlling continuously during photographing, and performs focus controlling of the taking lens. When a button 15 is moved in the arrow direction in this state, the automatic focus control circuit 21 is locked of its operation. When the change-over knob 12 is set at the SA position, the mode of performing automatic focus controlling only once at the first photographing is set and when the button 15 is operated in the arrow direction in this state, the automatic focus controlling is accomplished once every time when it is turned on once.

Title: Small gear pump and water purification device using the pump
Inventor: HARADA YOSHIO
IPC: C02F1/00
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To feed a fluid along a plurality of directions with a single pump by using helical gears as a pair of fluid feed gears operated with a drive motor, and mounting a plurality of pairs of a suction pipe and a delivery pipe respectively on a casing with mounting directions kept opposite to each other. SOLUTION: When a drive motor 20 is normally rotated, a ball 16 in the valve 10 of a suction pipe 6 moves upward against the force of a spring 17, due to negative pressure and at the same time, a valve 18, while radially contracting, releases the pressed contact thereof with a support plate 13. As a result, a fluid is drawn into a easing 1 via the suction pipe 6, and the pressure of the fluid is raised, due to the engagement of a pair of helical gears 3. Then, the fluid rises in a delivery pipe 8 and the pressure thereof forcibly opens the valve 18. As result, the fluid is discharged outside. On the other hand, when the drive motor 20 is reversed, negative pressure is applied to the valve 11 of another suction pipe 7, and the valve inside is opened. Consequently, the valve 18 inside the pipe 7 is opened, thereby delivering the fluid from the suction pipe 7 to a delivery pipe 9.

An operation and storage device 6 successively stores a digital signal value that is its output signal and also calculates the difference between a digital signal value stored the last time and a digital signal value of this time. A deciding device 8 decides whether the difference of the digital signal values is within the set values stored in a setting device 7 with high accuracy in addition to whether the digital value of an analog signal is within an operation area. Thus, an A/D converting device which is highly safe can be obtained.

Title: Constant rotation control of diesel engine
Inventor: SANO YUKINORI
IPC: F02D41/40
Filed: 1984-06-18
Abstract: PURPOSE:To achieve stable rotation control by obtaining a target rotation from the sum of rotation detected through an acceleration and the idling based on the engine operating condition then determining the setting rotation from a regulated rotation obtained through proper processing of same rotation with said target rotation. CONSTITUTION:A fuel injection pump 1 will regulate the fuel injection by moving a rack rod 5 axially through an electromagnetic actuator 10 where the actuator 10 is controlled through a control circuit 13. Here, the sum of roration detected through an accelerator position sensor 14 and the idling to be determined from the engine operating condition is employed as the target rotation then the error between said target rotation and the actual rotation detected through a rotation sensor 12 is integrated to produce a regulated rotation. Then it is controlled such that the actual rotation is matched with the target rotation through fuel injection based on the setting rotation which is the sum of the target rotation and the regulated rotation and the fuel injection based on the actual rotation.

Title: Improved wall surface burner type duct heat and method of controlling thereof
Inventor: RARUFU AARU BUOSUPAA
IPC: F23C5/02
Filed: 1980-09-06
Abstract: A heater (2) for heating gases such as turbine exhaust gases to facilitate the extraction of the heat energy carried by such gases or flue gases to reduce their corrosiveness. The heater is defined by burners (16) installed on walls (8) of the duct (4) through which the gases flow. The burner can be operated with heavy fuel oil and normally uses no more primary air than is necessary to ignite the fuel oil atomized by the burner and sustain a flame (18). The flame is relatively long and narrow and is directed transversely to the gas flow into the duct. Upstream of the burner is a shield (22) to protect the flame from the gas flow. The shield communicates with a register (50) which collects an amount of gas sufficient to provide the balance of the combustion oxygen to fully combust all fuel. From the register the gas flows along inclined passages (66) to the side (24) of the shield (22) facing the flame, the passages directing the gas in the direction of the flame and at an oblique angle in regard thereto. The flame shield is shaped to approximate the outline of the flame. Gas not collected by the register is guided by the shield past the flame so as to achieve a uniform heating of the gas and thereby prevent the formation of hot spots in the gas downstream of the heater. For operation in gas streams having a low oxygen content the burner (234) is constructed so that the fuel-to-combustion oxygen ratio in the upstream and downstream portions (230, 232) of the flame (relative to the exhaust gas flow)  is substantially equalized.

Title: Bias magnetic field generator for photomagnetic recording
Inventor: OGAWA KOUICHI
IPC: G11B11/10
Filed: 1984-06-15
Abstract: PURPOSE:To make high-speed recording and erasing possible by forming the center part of a device, whose section has two recessed parts in one side, with semihard magnetic materials and forming the other parts with soft magnetic materials and winding a coil around one side of the center and flowing a pulse current corresponding to recording/erasing signal. CONSTITUTION:The center part of this device is formed with semihard magnetic materials 5, and the other parts are formed with soft magnetic materials 6, and a magnetic path having not a magnetic path length A-B but having a magnetic path length A-B-C is formed by magnetic materials; and since magnetic poles A and C or D different from each other are arranged close, demagnetizing fields acting among magnetic poles A, B, and C and among magnetic poles A, B, and D are reduced considerably because magnetic resistances between magnetic poles are very low, and a stable powerful magnetic field is generated just under the magnetic pole A. The surface of the magnetic pole A consisting of semihard magnetic materials 5 is arranged orthogonally to a track to record and reproduce information on and from the track. Since the intensity of the magnetic field impressed to a recording medium is determined by the sectional area and the residual magnetic flux density of the semihard magnetic materials 5, the inductance of the magnetic circuit is reduced without requiring the increase of the number of turns of the coil.
