Title: Recording and reproduction system for control signal of rotary magnetic head type vtr equipped with fixed magnetic head for overall-width erasure
Inventor: OOTA YOSHIHIKO
IPC: G11B5/008
Filed: 1980-12-04
Abstract: PURPOSE:To prevent the absence of a control signal during recording and reproduction by using a fixed magnetic head for overall-width erasure of a special double gap type. CONSTITUTION:When a fixed magnetic head Hec has the same reproduction priority between gaps g1 and g2, an interval (d) between the gaps g1 and g2, the repetitive frequency (f) of a control signal, and the running speed V of a magnetic tape T are so determined that d=nv/f (where n=1, 2, 3...). When the gaps  g1 and g2 differ in polarity, on the other hand, d=(2n+1)v/2f (where n=1, 2,  3...). The control signal is recorded on the magnetic tape at the gap g2 in the  running direction X of the magnetic tape T and the control signal recorded on the magnetic tape T at the gap g2 is erased when passing on the gap g1. In reproduction, two reproduction outputs by the gaps g1 and g2 are synthesized and outputted.

Title: Suction implement for floor
Inventor: YOSHIMI KAZUYOSHI
IPC: A47L9/02
Filed: 1990-06-28
Abstract: PURPOSE:To enhance the wear resistance of a front wheel by adopting a front wheel whose wheel diameter is large, and also, to prevent a noise from being generated due to a rotation of the front wheel by forming a front wheel projection port on the floor surface, and supporting axially the front wheel projecting from the front wheel projection port with a rotary shaft of a rotary brush so as to be freely rotatable. CONSTITUTION:A wheel projection port 19 is pierced in a position corresponding to a front wheel 17 in the side part of a suction port 3 on the bottom face of the lower case 4, and the front wheel 17 projects downward from the wheel projection port 19. The front wheel 17 is attached to a rotary shaft 14 of a rotary brush 10, and supported axially with the rotary shaft 14 so as to be freely rotatable through a wheel bearing 18. Also, the front wheel 17 has the wheel diameter being a little larger than the rotation diameter of brush hair of the rotary brush 10. Accordingly, since the wheel peripheral surface of the front wheel 17 becomes long, even if it comes into contact with the floor surface, it comes to be scarcely worn, that is, the wear resistance becomes satisfactory and the front wheel 17 is not worn down. Also, since the wheel diameter is large, even if it runs on the flooring plate floor, a noise by a rotation of the front wheel 117 and abutting on the flooring plate floor is not generated, and accordingly, this suction implement contributes to quiet sound inversion at the time of cleaning.

The beam B is made incident on the end surface 55 of a 2nd substrate 50 and converged on a 2nd waveguide 52, and the light is propagated in the 2nd waveguide 52 as (z)-axial polarized light (TM polarized light) by polarization mode conversion coupling and projected as the shaped light from its end surface. Consequently, the light is converted to a shape which has excellent light convergence characteristics.

Filed: 1987-07-08
Abstract: PURPOSE:To obtain a buffered FET circuit capable of high speed operation by interposing a transistor (TR) of source follower connected to a load via a level shift diode between an inverter section and a buffer section. CONSTITUTION:An input signal is given to an inverter section comprising a TR 5 being a driver and a TR 4 being a load. Then the output of the inverter section is extracted from a connecting point of the TRs 4, 5 and inputted to a TR 9 of a source follower of a buffer section via a TR 6 of the source follower at an intermediate section. The intermediate section consists of a series circuit con]prising the said TR 6, a level shift diode 7 and a TR 8 being a load, and since a delay from a connecting point 1 to a connecting point 2 between the diode 7 and the TR 6 from which an output of the intermediate section is extracted gives an in-phase signal to the TR of the source follower, high speed operation is attained.

Abstract: PROBLEM TO BE SOLVED: To realize a filter device, whose attenuation characteristic can be arbitrarily varied and controlled, with a small-scale constitution by variably setting the cut-off frequency of the output characteristics, which do not include aliasing noises, and the resonance degree of shoulder characteristics. SOLUTION: A filter 1 can variably control a cut-off frequency FC by setting a filter coefficient CFC in coefficient multipliers 10 and 11 and a resonance degree QC of shoulder characteristics by setting a filter coefficient CQC in a coefficient multiplier 12.

Abstract: PURPOSE:To put a stable optical switch having minimal insertion loss into the practical use by abutting the end surface of an input side ferrule on that of an output side ferrule in a split sleeve and replacing an output side ferrule which is to be inserted. CONSTITUTION:Two optical fibers on the input side and two optical fibers on the output side abut on each other in sleeves 5 and 6 with the aid of ferrules on the both end parts. The input side and the output side are fixed to the sleeve and a ferrule holder 10, respectively. The energizing of a ferrule inserting and removing means 20 attracts the holder 10 to pull out the output side ferrule. In this state, when the rotating magnetic fields of a ferrule rotating means 30 are sequentially conducted, the holder 10 rotates by 180 deg.. When the energizing of the means 20 is stopped, the holder 10 returns to its original position due to the action of a spring, and the connection of the optical fiber is switched. Thus the stable optical switch having minimal insertion loss can be obtained.

Abstract: PURPOSE:To improve the effectiveness of defect inspection work by an operator by displaying only the defects which are easily overlooked in the center of a monitoring screen when an image in which a defect is found is displayed on the monitor for confirmation. CONSTITUTION:A wafer 1 exposed by using an reticle to be inspected is prepared and mounted on a X-Y stage.

If there is a defect in a light receiving area a31, the defect is transferred to the read out images. Those images are compared one another and only the image in which a defect is found is displayed. The defect confirmation by image comparison in this way is carried out for the whole light receiving areas a31, b32 and the address of the defect is simultaneously detected. In the case the range of the defect is within a set range, the image of the defect is displayed in the center of the monitoring screen to make the confirmation easy.
