Title: Tilting device of optical horizontal plane
Inventor: TANAKA YUTAKA
IPC: G01C15/00
Filed: 1983-07-01
Abstract: PURPOSE:To obtain an optical horizontal plane tilting device which determines the set height of a light receiving sensor visually by constituting the device so that a visible light and an invisible light are irradiated with the same optical axis. CONSTITUTION:The light irradiated from an invisible light emitting element 11 becomes a parallel light by a lens 12, and the visible light irradiated from a visible light emitting element 8 becomes a parallel light by a lens 7, and they pass through a semitransparent prism 6 and are focused in a position of a focal length f2 by a correcting lens 5. The focused invisible light becomes a parallel light by an object lens 4 and is emitted in the horizontal direction by a double- reflection optical path changing prism 2, which is rotated with a certain rotation number, to form a laser horizontal plane of the invisible light. The angle of inclination of the horizontal plane is graduated to correspond to a scale 16 provided on a micro knob 15, and the laser plane and a visible light plane are inclined simultaneously.

Title: Float valve
Inventor: SAWANOBORI NORIO
IPC: F16K31/18
Filed: 1983-07-01
Abstract: PURPOSE:To realize automatic closure of a valve by empty weight when piping gets out into gas by providing a suction valve formed by a float, pilot valve and bellows. CONSTITUTION:When gas is absorbed from a suction pipe, since a float chamber is filled with gas, a float 4 lowers due to its empty weight and pushes down a main valve disc 1 through a pilot valve 2. When the suction pipe is immersed in liquid, the float 4 is gradually floated due to its buoyancy and the pilot valve 2 is put in open state. By pressure difference due to difference between the inside sectional area of bellows 3 and the area of the main valve, the bellows 3 contracts and the main valve disc 1 is raised.

Title: White compression device for video signal
Inventor: NOMURA MASAYUKI
IPC: H04N5/20
Filed: 1986-05-22
Abstract: PURPOSE:To widen the reproducing range of a gradation with scarcely deteriorating the picture quality by controlling the compression start point of a white compression according to the white peak level of a video signal. CONSTITUTION:According to the output of a differential amplifier circuit 7, the white compression start point is controlled and the output level of the differential amplifier circuit 7 is controlled by a control circuit 4. For instance, the output level of the differential amplifier circuit 7 is controlled so as not to have the compression start point below 80% of a standard signal level. In a white compression circuit 5, the output of the control circuit 4 applied to a control terminal 3, accordingly, the start point of the compression is changed correspondingly to the output of the differential amplifier circuit 7 to perform the white compression. Namely, when the white peak level is comparatively low, the compression start point is made high and when the white peak level is comparatively high, the compression start point is made low, thereby, the reproducing range of the gradation can be fully taken with hardly deteriarating the picture quality.

The shifting stage 30 is lifted by rotating an adjusting screw 40, and each electrode 40 of the semiconductor chip 10 is brought close to the bonded part 30a of each lead 3 so as to perform alignment. After that, each electrode 10a of the semiconductor chip 10 is separated from the bonded part 3a of each lead 3 by lowering the shifting stage 30 so as to adjust the quantity H of gal wing. This way, by the descent of the shifting stage 30 by the adjusting screw 40, the distance between each electrode 10a and the junction 3a of each lead 3 can be adjusted, so the adjustment of the quantity H of gal wing can be performed accurately and freely.

Title: Floating type magnetic head
Inventor: TSUCHIYA MASAHIKO
IPC: G11B5/60
Filed: 1988-05-16
Abstract: PURPOSE:To stabilize the depth of a gap by forming a ferromagnetic metallic film only for a prescribed thickness on the facing rear surface of the recording medium of a magnetic head core. CONSTITUTION:A metallic magnetic film 3 is formed only for a prescribed thickness at a recording medium facing surface and the thickness becomes the depth of a gap 6. Consequently, the length of a gap part 6 is determined by the thickness of a non-magnetic material 5 and the depth is determined by the thickness of the metallic magnetic film 3. A nonmagnetic material 4 is formed in order to prevent an I core 1 and a U core 2 from directly contacting at the gap part 6, the thickness of the same extent as the thickness in the vicinity of the gap part 6 of a U core 2 is satisfactory, and the thickness about 1-5 times as much as the thickness of the metallic magnetic film 3 is suitable. Thus, the depth of the gap 6 is stabilized and a magnetic head without a pseudo gap can be further obtained.

Filed: 1992-05-12
Abstract: PURPOSE:To facilitate adjustment of optical axis while preventing erroneous function due to optical interference with an adjacent photoelectric switch and to prevent deterioration in the detection of distance and of noise resistance. CONSTITUTION:A flash light circuit 13 outputs light pulses of such number as set by a flash light pulse number setting circuit 12 at a predetermined time interval in the first flash light operation. A light receiving circuit 15 receives the light pulse and delivers a light receiving pulse through an amplifier 16 and a comparator 17 to a detecting circuit 18, which outputs a light receiving detection signal. only when the number of light receiving pulse signal matches with a number N set by a light receiving pulse number setting circuit 22. When the number of pulse (n) is set at N, light receiving state can be detected only when a light pulse is received from the flash light circuit 13. This constitution prevents erroneous detection and facilitates adjustment of optical axis by obviating the necessity of making narrow the beam of flash light without sacrifice of detecting distance.

A high-order mode generated in the cavity 1 is coupled with a TM01, or TE11 mode generated in the pipe 3 and is absorbed by the absorber 4. The length of the pipe 3 is varied between the cavity 1 and one end of the absorber 4 using the mechanism 5 to move the absorber 4, and a Q value is adjusted to a minimum to match the electromagnetic field distribution of the high-order mode. The position of the absorber 4 is thus optimized and the aimed high-order mode is absorbed sufficiently.

Abstract: PURPOSE:To enhance reliability by depositing a laminated metal in such a manner as entirely covering the surface of metal wiring formed by lift-off method and thereby eliminating short-circuit between the adjacent wirings which is resulting from separation of pattern edge in the post processing after the formation of wirings. CONSTITUTION:The conventional processes are executed until a pattern of titanium and platinum is formed. Then, a photo resist pattern 4' is formed as a protection film of gold plating. This photo resist pattern 4' is formed on a spacer 3 formed by the lift-off method. Namely, the edge 8 of pattern of titanium and platinum is exposed before the gold plating and therefore the photo resist pattern 4' is formed so that the surface is covered with gold by the gold plating. When the gold plating completes, the pattern of platinum is perfectly covered with gold 7. Next, the photo resist pattern 4' is removed by the ordinary method and finally the unnecessary spacer 3 is removed, thereby completing formation of metal wirings.
