Title: Level meter device of accoustic apparatus
Inventor: HIRAYAMA ETSURO
IPC: G09G5/00
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To immediately display a level meter during the analog recording to adjust the recording level by automatically switching the display of the level meter to ON when analog recording is carried out and the level meter is OFF during the recording operation. SOLUTION: With an instruction for analog recording by a key matrix 7, an audio input signal 12 is level-adjusted by VR1. Thereafter, the signal 12 is recorded to a mini-disk via optical pickup assembly 15 from an analog/digital converter 10. In this case, even when an instruction is issued to made off the level meter display of the display unit 8 with the key matrix 7, the level meter display is automatically turned OFF with the control of the system controller 5 during the analog recording and the recording level can be adjusted using VR1. Thereby, the procedure to manually turn ON the level display can be eliminated to improve application flexibility.

Title: Multi-optical beam scanner
Inventor: KAMIOKA MAKOTO
IPC: G02B26/10
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To provide an optical device, in which the required output power of the light source is reduced, the quality of the picture is improved and the mass-productivity is increased, by providing a shaping lens system, a polarizing means, an optical element, a deflector and a scanning lens system. SOLUTION: When optical beams 3a and 3b, which are linearly polarized and have mutually different polarization directions by 90 degree, are made incident on a prescribed polarization beam splitter 4, the beam 3a is reflected at an approximately 100% level by the splitter 4 and led to a deflector 24. On the other hand, the beam 3b passes through the splitter 4 at an approximately 100% level and is led to the deflector 24. The beams 3a and 3b, which are let to the deflector 24, are deflected by the deflector 24, pass a scanning lens system 25 and scan a surface 30 to be scanned.  Thus, by converting the two beams 3a and 3b, which are to be made coincident on the same directional optical axis, into mutually different linear polarization directions by 90 degrees and passing them through the splitter 4, the loss of the light quantities of the beams 3a and 3b, which are led to the deflector 24, is suppressed and as a result, the required output power of the light source is reduced.

IPC: B60L3/00
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To eliminate a current transformer for the detection of the misignition of a thyristor in a DC filter circuit. SOLUTION: A current applied to a thyristor 11 is detected simultaneously with a current applied to a conventionally provided filter capacitor 5 by a current transformer 17 which detects the current applied to the filter capacitor 5 and supplied to a thyristor operation judging means 22. If the current transformer 17 detects a current whose direction is opposite to the direction of the current normally applied to the filter capacitor 5 and the detected current value is approximately equal to a value which is obtained by dividing the voltage of the filter capacitor 5 which is detected by a voltage detector 16 by the resistance value of a resistor 12 and, further, an off-instruction is given to the thyristor 11, the thyristor operation judging means 22 judges that the misignition of the thyristor 11 exists.  With this constitution, by changing wiring patterns 20 and 21 only a little, a current transformer which is required in a conventional constitution for the detection of the thyristor current in addition to the current transformer 17 for the filter capacitor 5 can be eliminated and hence the number of components is reduced.

Filed: 1980-03-18
Abstract: PURPOSE: To improve sealing performance and durability of a mechanical seal, by applying porous chrome plating over one of the sliding surfaces of the mechanical seal and making the other with a carbon material.  
     CONSTITUTION: In a mechanical seal 30 shown in the drawing, a rotatable ring (rotary piece) 38 is made of a carbon material, and porous chrome plating 40 is applied over the surface of a sheet ring (fixed piece) 31 onto which the ring 38 is urged by the resilient force of a spring 36. With such an arrangement, it is enabled to lower the friction factor on the contact surface and also to reduce their specific wear remarkably. Therefore, in a mechanical seal 30 for use, for instance, in a swash plate type compressor in which rotation is continued with supply of a small amount of or no lubricating oil, the amount of leakage oil can be reduced to less than one half of that in the conventional arrangements. Further, leakage of oil during long use can be also lessened and durability of the seal can be improved if they are compared with those of a seal consisting of a combination of a high-hardness layer and a carbon material.
