Title: Solar water heater
Inventor: AYUSAWA MASANOBU
IPC: C22C9/04
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To enhance dimensional accuracy of water channel and corrosion resistance by composing the water channel of a brass member having apparent wt.% content of Zn within a specified range, containing Sn at a ratio within a specified range, and having crystal texture of specified average grain size or less. SOLUTION: A channel unit 6 is formed by forging a brass member having apparent content of Zn in the range of 37-46 wt.%, containing Sn by 0.5-7%, and having such a crystal texture as the average grain size is 20 μm or less. Since a brass member having such a crystal texture includes β phase in crystal texture, cutting performance is enhanced and since Sn is contained in β phase, resistance against dezincification corrosion is enhanced. Furthermore, high temperature corrosion resistance is enhanced and erosion resistance is also satisfied. Consequently, a water channel member excellent in resistance against high temperature corrosion, dezincification corrosion and erosion and excellent in cutting performance can be obtained.

Title: Fuel injection control device
Inventor: YOSHIOKA SHIGEKI
IPC: F02C9/28
Filed: 1982-04-14
Abstract: PURPOSE:To prevent decrease in a fuel injection quantity when a battery voltage drops, by arranging such that there may take place a reduction of resistance value in a resistor connected with a solenoid valve for controlling an electric current in response to a voltage drop, in a fuel injection control device for a gas turbine engine. CONSTITUTION:While a start signal S7 is retained ON, a transistor 8 is turned ON and a relay 9 is energized, thereby causing a contactor of the relay 9 to switch ON for starting an operation. Upon the contactor of the relay 9 being switched ON, the relay 10 is also energized for turning ON all of its four contacts. Thus, a resistor R2 is short-circuited and solenoid valves 6 and 7 are brought into contact with a battery VB solely via a resistor R3. In this manner, solenoid valves 6 and 7 are energized with an ample voltage even when a battery voltage drops at the start-up operation, thereby allowing these valves to receive an ample driving current in response to signals S5 and S6 indicative a fuel injection timing.

Title: Wave guide type light/sound spectrum analyser
Inventor: NISHIMOTO YUTAKA
IPC: G02F1/125
Filed: 1987-03-18
Abstract: PURPOSE:To enhance a dynamic range, by mounting a metal membrane to a wave guide before non-polarized light is removed from the wave guide. CONSTITUTION:A metal membrane 25 composed of aluminum, chromium, gold or titanium is mounted between a collimation lens 13 and the position where collimated beam 15 is polarized by an elastic surface wave 19. When both of P- and S-polarized beams are mixed in the laser beam incident on a wave guide 11 from a beam source 12 and further incident on a removing end surface 23, the S-polarized beam component is absorbed by the part of the membrane 25 to be attenuated since the vibration direction of an electric field is parallel to the thickness direction of the wave guide 11. Since the P-polarized beam component crosses the vibration direction of the S-polarized beam component at a right angle, said P-component propagates without being almost affected by the membrane 25. Therefore, the beam incident on the end surface becomes only the P-polarized beam component and the removal of non-polarized beam 17 into the air from the wave guide 11 is performed according to the object and the non-polarized beam reflecting from the end surface 23 is almost lost. By this method, the enhancement of a dynamic range can be achieved.

CONSTITUTION:In the operation of a circuit, printing data 18 is inputted to a register 33 at first. Thereafter, the printing data 18 of one line is held to a latch circuit 34 and, at the same time, the correction data of the light emitting data of an LED array unit is inputted to a correction data latch circuit 30 from a correction memory 12. This circuit 30 outputs the correction data to the AND gate circuit 35 of the LED driving IC driver 11 of each LED. The coincidence of the printing data and correction data held to the latch circuit 34 is taken by the circuit 35 and the driver circuit is digitally driven only for an output time of '1' to be subjected to the light emission of an LED array 10. By this method, light emitting time can be controlled at the LED array unit of each stage.

Filed: 1985-03-26
Abstract: PURPOSE:To eliminate transmission modulation components invaded in a reception wave by modulating the 2nd local oscillating section of the reception side with a transmission input signal in a transceiver where received local oscillation output is modulated to generate a transmission frequency. CONSTITUTION:A voice signal 113 inputted from a microphone is fed to the 1st local oscillating section 10 at simultaneous transmission/reception. The local oscillation section 10 is used in common as a transmission modulation stage to send a transmission frequency signal 10a modulated by the voice signal from an antenna 1 via a transmission/reception common use filter 2. On the other hand, the input signal received from the antenna 1 is converted into the 1st IF signal 104 by the 1st reception mixer 4. In this case, a voice signal component 22 is included in the 1st IF signal 104. The 2nd local oscillation section 11 is modulated by a signal phase-shifting the transmission voice signal 113 thereby eliminating an unnecessary transmission voice signal included in the 1st IF signal 104.

Title: Image forming method
Inventor: WANO MASAHIRO
IPC: G03G15/00
Filed: 1986-03-19
Abstract: PURPOSE:To attain recording at a low voltage without thickening an image carrier by impressing a prescribed electrostatic charge voltage to the image carrier by a switching means to uniformly charge the image carrier, exposing a positive image by an exposing means and then impressing a developing bias voltage to the positive image to develop it. CONSTITUTION:The switching means 6 connects an electrifying power supply 4 at the 1st rotation of the image carrier 1 to uniformly electrify the image carrier, and at the 2nd rotation, connects a developing bias power supply to form a toner image on the image carrier 1. Namely toner is prevented from being transferred from a rotary brush 1a to the image carrier 1 by impressing the electrifying voltage to the rotary brush 3a and selecting the reverse polarity of the toner to electrify the image carrier 1. Therefore image formation is restricted only the process of positive exposure and positive development to stick the toner with the reverse polarity to the charge of an image part. Consequently, the image carrier 1 can be electrified by a developing means 3 and one recording can be executed by two rotations of the image carrier 1.
