Title: Type clamping device for typewriter
Inventor: HAMADA TSUTOMU
IPC: B41J1/14
Filed: 1981-06-05
Abstract: PURPOSE:To prevent types from dropping, avoid staggering in printing, restrict correctly the lines and columns printed on a recording paper and facilitate the adjustment of a printing mechanism as a whole, by a method wherein a type is rigidly clamped by amplifying a weak force immediately before printing. CONSTITUTION:When a type 3 is set in a predetermined position of a type bar 1 and an input cam 4 is rotated in the direction of an arrow Y, a type bar piece 2 enters a nick part 3' of the type 3 and a pressing arm 16 is moved by a projection 2', resulting in the condition of Fig 2. When the cam 4 is further energized continuously in the direction of the arrow Y, it starts to rotate around a pivot shaft for the type bar, resulting in the condition of Fig 3. At this point, a little gap S is provided between the outside peripheral surface of a pressing roller 18 and the outside peripheral surface of a drop-preventing cam 7. When the cam 4 is futher rotated, it collides against a projected part of an oscillating cam 7, resulting in the condition of Fig 4. In this case, even if the force of a pressing spring 8 is weak, it is amplified by a factor of several times by a wedge effect of the cam 7 and the roller 18, and the type bar piece is pressed through the principle of a lever. Accordingly, a sufficient force for clamping the type can be obtained.

Title: Ion thruster
Inventor: SMITH PETER
IPC: F03H1/00
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To prevent wear and corrosion of an accelerator grid obtaining reactive thrust by ion flow by composing the accelerator grid of a layer containing graphite and a support layer of the graphite contained layer. SOLUTION: A screen grid 7 maintained to positive potential cuts off ions drifting toward an accelerator grid 8 of negative potential. Ions 10 close to the screen grid 7 are attracted toward the accelerator grid 8 of negative charge to generate high speed exhaust flow and to impart reactive thrust to an ion thruster. To construct the accelerator grid 8, a molybdenum grid 14 is fixed to an upper surface 13 of a graphite block body 12 with an adhesive, and after cutting the block body 12 to form a reduced cylindrical block body, a lower surface of the block body is machined into the same curvature as the upper surface and into reduced graphite thickness. During machining, a molybdenum layer 14 structurally supports the thin graphite layer.

Title: Method and device for monitoring gas flow rate
Inventor: OKUMA HIDEAKI
IPC: F17D1/04
Filed: 1994-04-01
Abstract: PURPOSE:To monitor the gas flow rate with the saved power by using a one- pole double-throw type switch provided with a movable contact which is pivotably supported by a supporting point and two opposite contacts as a signal output switch of an ON-OFF type flow rate sensor to detect the presence/ absence of the gas flow rate in the gas piping. CONSTITUTION:In a switch of an ON-OFF type flow rate sensor, contacts (a), (b) are provided, and a movable contact (d) which is pivotably supported by a supporting point (c) is selectively abutted on these contacts (a), (b). When this switch is provided on a pressure sensor E of the piping system, the part between the contacts a-c is set to the closed condition, and the part between the contacts b-c is set to the open condition in the presence of the gas flow. The voltage is applied to the open contacts b-c and the open condition between the contacts b-c is confirmed. When the contacts b-c are closed, the current flows, and the voltage is dropped to allow the judgement of the open/close of the contacts. The presence/absence of the gas flow rate is judged by monitoring the open condition of the contacts b-c.

An n-type well CMOS tenology is coupled with the process of the CCD, for obtaining the best features from the both technologies of CMOS and CCD.  Thereby, the defect of the response to the blue light of the sensor, the defect of the lag of the image of the sensor and the defect of a high dark current in the sensor are minimized.

Title: Optical isolator
Inventor: MASUMOTO TOSHIAKI
IPC: G02B27/28
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To provide an optical isolator which uses a polarizer requiring no polishing process and which is more inexpensive without increasing the insertion loss or the loss in the opposite direction although the dispersion of polarized waves is zero. SOLUTION: The incident light in the forward direction is divided according to the components of polarized light by transmission or reflection by a first reflection type polarizer 1. The reflected light is converted by a first reflection mirror 3 into light in the parallel direction to the propagation direction of the incident light in the forward direction to enter a 45 deg. Faraday rotator 5 and to enter a second polarizer 2. The polarized light component transmitting through the first polarizer 1 is transmitted through the 45 deg. Faraday rotator 5 and then reflected by a second reflection mirror 4 to enter the second polarizer 2.  When the light is reflected by the second polarizer, the light is mixed with the light which is reflected by the first polarizer 1 and guided to the second polarizer and transmitted to transmit so that the optical path length of these optical paths is made equal to each other.
