Title: Full-wave rectifier
Inventor: IKEHATA MASATOSHI
IPC: H02M7/21
Filed: 1991-10-08
Abstract: PURPOSE:To symmetrically output half period of a rectified output current with respect to an input voltage signal. CONSTITUTION:If an input voltage signal v1 is at a duration of a half period of a positive side in a case where the signal is input to an input terminal 11, an emitter current of a transistor Q11 flows to a resistor R11. Accordingly, a collector current of the transistor Q11 is output to a rectified output current terminal 12. Then, when the signal is at a duration of a half period of a negative side, an emitter current of a transistor Q12 flows to the resistor R11. Therefore, a collector current of a transistor Q13 is output to the terminal 12. Since a current amplification factor of a common-base type transistor is the same as that of a transistor having the same polarity, the collector current of the transistor Q11 becomes the same value as that of the transistor Q13. That is, the rectified output current becomes symmetrical to the signal v1 in each half period.

Title: Air flow direction changing device
Inventor: MUTO YOSHIO
IPC: F24F13/15
Filed: 1985-11-20
Abstract: PURPOSE:To make it possible for a user to readily select whether a louver is stopped by taking an air flow direction at the stop position of the louver into consideration beforehand by stopping the louver at a predetermined position when a louver for changing the air flow direction is stopped in an air conditioner or the like. CONSTITUTION:When a drive switch 48 is opened, power supply from a power source VDD which has been applied to the terminal 47 of an OR circuit 45 is stopped. However, since one input terminal 46 is of a high level voltage, a drive motor 32 does not stop. Thereafter, when light emission of the light emission element 40 of a photointerrupter 39 is detected by a light receiving element 41 via a cutaway portion 42, the OR circuit 45 outputs a low level voltage to make a transistor 50 non-conductive and d-eenergize a relay coil 54. For this reason, a relay switch 53 is opened and power supply to the drive motor 32 is stopped. Since position where the cam plate 35 stops upon this occasion is a position where the louver faces the front surface, hot air is discharged constantly toward the front surface at the time of stopping the cam plate 35.

Abstract: PURPOSE:To expand the degree of freedom of an optical wavelength split multiplex transmission system by using a frequency conversion system to apply frequency conversion to a signal before it is inputted to an optical transmission section in advance so as to almost avoid the electric crosstalk between signals. CONSTITUTION:A frequency converter 16 applies the frequency conversion to a signal frequency conversion inputted from an information signal input terminal 10 into the frequency of f3-f2.

An optical signal in a wavelength lambda1 is led to an optical recep tion section 6 and an optical signal in a wavelength lambda2 is led to an optical reception section 7 while being branched respectively. A signal passing through a band pass filter 18 is frequency-converted by the frequency of an oscillator 15 at the frequency converter 16 and the information signal of the frequency component f2 is outputted at a terminal 13. The signal is converted into an optical signal while electric isolation is applied in advance and the optical isolation is applied between optical signals by optical wavelength multiplex.

Title: Alkaline battery separator and alkaline battery using the separator
Inventor: TANAKA MASANAO
IPC: H01M2/16
Filed: 1993-09-24
Abstract: PURPOSE:To provide a separator almost free from the ingress of an electrolyte, while having the high capability for holding an electrolyte and almost ensuring freedom from short-circuit due to dendrite by forming the separator out of water flow leno nonwoven fabric containing the bridged state of polyvinyl alcohol having the specified constitutional unit. CONSTITUTION:An alkaline battery separator is constituted of water flow leno nonwoven fabric containing the bridged state of polyvinyl alcohol having a constitutional unit expressed by the general formula I, where R1 stands for a quaternary aromaticity complex cyclic residual group containing nitrogen, R2 for a hydrogen atom or an alkoxy group and R3 for a hydrogen atom or an acyl group. Also, (m) stands for 0 or 1, and (n) for a natural number between 1 and 6. For an alkaline battery, this separator is employed. The bridged polyvinyl alcohol has affinity with an electrolyte, and is excellent in holding the electrolyte. In addition, the fiber of the water flow leno nonwoven fabric is generally oriented toward a thicknesswise direction. Thus, a certain degree of thickness can be maintained against the expansion of an electrode or the like. Thus, the separator comes to have the higher capability of holding the electrolyte.
