Title: Safety indwelling needle
Inventor: NAKAJIMA HIROAKI
IPC: A61M5/32
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To provide a safety indwelling needle with a good operability capable of being used in the state that a housing is shrunk to a compact size with outstandingly simple means and being wasted and retained as such without contacting the needle with a simple operation that the housing itself is only elongated after used without using a conventional needle guard requiring a time to slide and assemble. SOLUTION: A housing 1 is removal-stop connected by a plurality of connection tubes 1a1, 1a2, 1a3 and is assembled so as to elongate/shrink in a longitudinal direction. As a removal-stopping method of these connection tubes 1a1, 1a2, 1a3, the connection tubes 1a2, 1a3 inserted are formed so as to be gradually thick toward a base end side and may be assembled such that a press-contact force is cooperative not so as to be removed off at a terminal end. Accordingly, before using, the housing 1 can be retained in the state that the housing 1 is shrunk to a short size and after using, a needle 3 can be wasted and retained as such with a simple operation that the housing 1 itself is only elongated.  So long as the connection tubes 1a2, 1a3 are pushed and returned in resistant to the removal-stop press-contact force, the housing 1 is not easily shrunk and an unintentional needle-sticking accident by a used needle can be prevented.

Title: Automatic white balancing device
Inventor: MINOBE TADASHI
IPC: H04N9/73
Filed: 1988-03-11
Abstract: PURPOSE:To realize accurate white balance at low cost by correcting the level ratio of a color signal separated from a video signal based on a discriminated spectral characteristics at the value equal to the level ratio obtained with the natural light or the light of an incandescent lamp. CONSTITUTION:The spectral characteristics of photoelectric transducing elements 1a-1c are different from each other and scattered properly within a range of the spectral characteristics of an image pickup device 4. An arithmetic means 3 discriminates the spectral characteristics of the external beams incident on the elements 1a-1c based on the relation between the input signals Aa and Ac and also outputs the gain control signals Aa1 and Ac1 which are obtained by giving the correction to the input division values Aa and Ac respectively. In other words, the level ratios among color signals R, G and B are corrected in accordance with the discriminated spectral characteristics of an illumination light source. So the said level ratios are equal to those obtained with the natural illumination light. Thus it is possible to ensure an easy white balancing action even with an illumination light source having the special spectral characteristics.

Title: Composite material of ceramic and metal
Inventor: YAMANE KENJI
IPC: B23P11/02
Filed: 1985-03-22
Abstract: PURPOSE:To produce a low-cost composite material, by a method wherein a ceramic base material is shrink-fit in the fastening part of a ceramic member, consisting of a metallic base material, which is low cost and easy to machine, through a metal having the low coefficient of expansion. CONSTITUTION:A pure titanium ring 3 is shrink-fit in an alloy 1 made of stainless at about 220 deg.C (as shown in fig. A). Thereafter, the titanium part is cut (as shown in fig. B), and a seal ring 2 made of ceramic is shrink-fit in the titanium part at about 220 deg.C. In which case, fastening allowance of ceramic is about 0.04mm, and even if ceramic is cooled to a room temperature, it is prevented from break. Further, even if it is heated to 180 deg.C, the pure titanium ring and the seal ring are prevented from separation. Thus, only a fastened part during shrink-fit of the metallic base material 1 forms a metal 3 which is difficult to machine and has the low coefficient of expansion, and other part forms a metal which is low cost and easy to machine, and this provides a low cost composite material in terms of both a material cost and easiness in machining.

Title: Distortion correcting method for display device
Inventor: KABURAGI CHIHARU
IPC: G02F1/133
Filed: 1991-03-22
Abstract: PURPOSE:To stably and accurately correct the distortion of a display image by sampling the angular velocity of a reflecting mirror which moves reciprocally in a specific range and controlling the light emission intervals of a light emission element array according to the sampled value. CONSTITUTION:An AD converting circuit 3 samples and digitizes the angular velocity signal 101 of the oscillatory mirror according to a sampling signal 106 and a decoder 4 outputs an address corresponding to the value of the sampled angular velocity to a ROM 5. The ROM 5 stored previously with correction quantities corresponding to respective angular velocity values loads a correction quantity in a specified address to a counter 6, which performs counting operation by the correction quantity. A control circuit 7 on receiving the counting end signal of the counter 6 sends a strobe signal 105 to an LED array 2, which emits light. Consequently, even if the angular velocity deviates from an expected value owing to the solid difference, disturbance, and secular change of the oscillatory mirror, the light emission interval control over a line matching the actual angular velocity signal variation is performed.

The rod lens 12a which constitutes the rod lens array 5a is formed of >=2 kinds of polymerizing monomers which differ in polymerizing speed and refractive index after polymerization and has a refractive index shown by an expression I. In the expression I, n(r) is the refractive index corresponding (r), (r) the distance from the center, n0 the refractive index in the center, and A<1/2> a refractive index distribution constant. The variance of the refractive index distribution constant is therefore small and the height of the lens can be made constant; and the need for a lens position fine adjusting mechanism is eliminated and the device which has the frame and a housing molded in one body is obtained. Consequently, the low-cost, high-performance image sensor which is easily assembled and adjusted is obtained.

Title: Three-position operation mechanism for electronic equipment
Inventor: HOSOYA RYOZO
IPC: H01H33/40
Filed: 1993-02-23
Abstract: PURPOSE:To prevent an intermediate position stopper and a mode switching mechanism from competing with each other and enable accurate positioning at an intermediate position by structuring stopper functions and the mode switching function individually at the intermediate position and providing the stopper functions on both sides. CONSTITUTION:At the time of operation from a movement position of a mode 1 to the intermediate position, a driving lever 5 rotates anticlockwise and receives an operation load by a lower latch 19 through the connection shaft 10 of a mode switching lever 9, and an upper latch 15, an adjusting bolt 18, and a bearing 22, thereby functioning as a stopper. When a mode switching lever set frame 12 is lifted in this state for mode switching, the intermediate position stopper pin 11 and an intermediate position stopper hole 13 do not compete with each other and it is not necessary to reset the mechanism body after its operation. When the adjusting bolt 18 is made long, the angle of rotation up to a collision becomes small and when the bolt is made short, the angle of rotation becomes large. Consequently, the positioning at the intermediate position is adjustable and the correct intermediate position is obtained.
