Title: Container for semiconductor wafer cassette
Inventor: SEKIGUCHI TAKESHI
IPC: H01L21/673
Filed: 1990-01-17
Abstract: PURPOSE:To make adjustment so as to prevent the occurrence of a differential pressure even when a differential pressure is produced between the inside and outside of the title container by a temperature difference, etc., between the inside and outside so that no contaminated air can be sucked into the container by providing a differential pressure adjusting means which adjusts the differential pressure between the inside and outside of the container. CONSTITUTION:In the case a differential pressure is produced between the inside and outside of this semiconductor wafer cassette container 10 when the container 10 is moved with cassettes for wafer inside, the inside pressure of the container 10 is maintained at a fixed level by means of an elastic deforming section 12 which makes elastic deformation in accordance with the differential pressure. Namely, when the inside pressure becomes higher than the pressure of the outside air, the section 12 deforms outward and the volume of the container 10 increases, resulting in a reduction in the inside pressure and a balanced state between the inside and outside pressures. Therefore, entrance of the outside air into the container 10 can be prevented and the cleanliness in the container 10 can be maintained regardless of the change in the inside pressure.

Title: Shift device for inboard and outboard engine
Inventor: HARADA NORIMICHI
IPC: F16H63/30
Filed: 1982-01-22
Abstract: PURPOSE:To ensure shifting forward and backward by fitting a top expanded part of a shift arm operated by a remote control cable into a fork within the range of standard oscillation to complete clutch shifting and releasing it outside this range. CONSTITUTION:When an inner 38 of a remote control cable 34 moves from a neutral position to a forward side or a backward side, a shift arm 43 is oscillated. Within the range of the stroke of the cable 34 corresponding to a standard oscillation range, the displacement of a shift fork 45 is changed linearly to complete the shift operation. At this completion, a pawl part 26B or 26C of a clutch  26 is advanced to engage with a pawl part 24A of a forward gear 24 or a pawl  part 25A of a backward gear 25 to a rotate a drive shaft 27 forward or backward. When the shift fork 45 reaches the shift end, an expanded part 46 of the  shift arm 43 is released from an engaged face 49A or 49B of the fork 45 for running idle in oscillation. This construction permits to shift clutch without fail  even if the stroke of the remote control cable is changed.

Title: Magnetic head
Inventor: KITATANI AKIO
IPC: G11B5/23
Filed: 1991-01-25
Abstract: PURPOSE:To improve the mass-productivity by forming so as to prohibit the protrusion of low melting point glass to the bottom surface of an opposite side against the sliding surface and griding the sliding surface by making the bottom surface in the opposite side against the sliding surface as a reference plane. CONSTITUTION:Since the depth of the groove 5 is formed so as to be shallower from the surface corresponding to the sliding surface 15 to the surface 14a corresponding to the bottom surface in the opposite side against the sliding surface 15, the low meting point glass 3 is not protruded on the surface 14a when the low melting point glass is filled. Thus, the surface 15a corresponding to the sliding surface 15 can be ground flatly by making on the surface 14a corresponding to the bottom surface 14 in the opposite side against the sliding surface 15 as a reference plane. Thus the rereferencing stage is unnecessary, when the surface 14a is used as a reference plane, and also the degradation of the accuracy by rereferencing does not occur and the mass-production of the magnetic head is improved.

Title: Faraday rotating device
Inventor: KOMATSU JIYUSAKU
IPC: H01S3/101
Filed: 1979-01-25
Abstract: PURPOSE: To simultaneously obtain the uniformity in time and space with a simple constitution by winding an auxiliary coil around a main coil in the specific direction.  
     CONSTITUTION: An auxiliary coil 8 is wound around a main coil 2 which contains a Farady roating element 1 coaxially at the central part, in such a manner that the direction of magnetic field becomes opposite from that of the magnetic field produced by the main coil 2. A main coil switch element controller 17 is operated by an external signal to let a switch element 3 conduct, thereby flowing current in the main coil 2 while absorbing the current having undergone polarity inversion by a diode 5. The intensity of the magnetic field growing in the main coil 2 is detected with a detector 14 and is inputted to a comparator 15. When the magnetic field intensity reaches the specified value, an auxiliary coil switch element controller 16 is operated to flow current to the auxiliary coil 8 through the switch element 9. Thereby, the non-uniformity in the time and space of the magnetic field produced by the main coil 2 is corrected by the non-uniformity in the time and space of the magnetic field produced by the auxiliary coil 8.

Title: Processing device of video signals
Inventor: KATO SHIRO
IPC: H04N5/21
Filed: 1985-01-21
Abstract: PURPOSE:To efficiently remove noise components near the start edge of the horizontal synchronizing signals among the signals by so arranging that a recursive comb-line filter is caused to act at only near the horizontal synchronizing signals among input video signals. CONSTITUTION:The video signals inputted from a terminal 11 are passed through a delay circuit 13 to be video signals delayed by time TD. The delayed video signals are inputted to one input of a switch SW21 and to the recursive comb-line filter 14. The filter 14 has a unit time delay quantity having an integral number of times of a horizontal scanning period and its output is outputted to the other SW21. The start edge of the horizontal synch signals in the input video signals is detected by a pulse generator 12 which then produces the control pulse of a time interval TC(>TD) beginning with the edge to control SW21. This SW21 selects the output of the filter 14 during the control pulse period and selects the delayed video signals during the periods other than the pulse period. In such a manner, noise components free from vertical correlation in the vicinity of the horizontal synchronizing signal can be efficiently removed.
