Title: Harmful light shielding device of zoom lens
Inventor: OGAWA HITOSHI
IPC: G02B7/00
Filed: 1979-11-05
Abstract: PURPOSE: To enable harmbul light to be well shielded in a wide range from wide angles to telephoto in a zoom lens having a diaphragm which shields harmful light behind the rear part lens group by so constituting that this diaphragm is moved in follow up to the movement of the rear part lens group.  
     CONSTITUTION: As a zoom ring 4 is rotated, a front part lens group 2 and rear part lens group 3 move in the optical axis direction, thereby changing the focal length. At this time, the arm 6 integral with the frame body 5 of the rear part lens group 3 also moves in the optical axis direction. If it is assumed that this moving direction is the right direction of an arrow, a diaphragm means 9 tries to rotate in the arrow (a) direction because the pin 8 of the arm 6 is held fitted in the groove 10 of the diaphragm means 9. On the other hand, the pin 14 of the diaphragm means 9 is held  fitted in the groove 15 of a rear cover 13; therefore, the diaphragm means 9 provided with a diaphragm moves and comes to the position where it well shields flare.  Thereby, the harmful light of all the range from wide angles to telephoto is well  shielded and the images of good quality is given.

Abstract: PURPOSE:To reproduce medium and low sound regions, by arranging the disc shaped 2nd piezoelectric oscillator at the center of each upper surface of a plurality of disc shaped 1st stage piezoelectric oscillators and driving the oscillators through the superimposition of each oscillation amplitude of the 1st and 2nd stage piezoelectric oscillators. CONSTITUTION:Three disc-shaped piezoelectric oscillators 5 made of a piezoelectric plate 52 sticked with a brass thin plate 51 are closely arranged, and legs 53 are bonded at the inside of bottom of a frame 2 and fixed. The disc-shaped 2nd stage piezoelectric oscillator 6 is bonded to the upper surface center of each piezoelectric oscillator 5 with the legs 63. The top of a circular cone type diaphragm 4 made of paper is bonded at the upper surface center of the oscillator 6. When the center of the oscillators 5 is bent, the center of the oscillator 6 is interlockingly bent. That is, the amplitude of the oscillators 5, 6 is superimposed to double the oscillation amplitude of the diaphragm of a speaker. Thus, a driving source enabling large amplitude and vibration can be constituted and medium and low sound region can be reproduced.

Filed: 1988-06-13
Abstract: PURPOSE:To reduce the response delay of an air-fuel ratio sensor in the transition to the feedback control by reducing the heating faculty of an air-fuel ratio sensor in the open loop control, in comparison with that in the feedback control. CONSTITUTION:In a control unit U, a signal for closing a relay switch 24a is outputted in the feedback control for air-fuel ratio, and an air-fuel ratio sensor 17 is kept at a prescribed activity temperature by a heater 21. While, in the case of the air-fuel ratio which is leaner than the air-fuel ratio in the feedback control in the open loop control for the air-fuel ratio, the control unit U opens the release switch 24, and the heating of the air-fuel ratio sensor 17 by the heater 21 is suspended. Therefore, the responsiveness in the transition from the open loop control to the feedback control is sufficiently secured, and the increase of the actual air-fuel ratio to an extremely rich state exceeding the theoretical air-fuel ratio can be prevented.

Title: Mass energy analyzer for neutral particles
Inventor: KARAUSHI HIROTERU
IPC: H01J49/46
Filed: 1989-06-06
Abstract: PURPOSE:To enhance the accuracy of analysis for the mass energy of neutral particles with low energy by dividing an electrostatic deflection plate which imposes electrostatic fields, into plural numbers to the directions of Larmer radii of incoming ions which are discriminated by means of Larmer revolution, and thereby also permitting the electrostatic fields which are to be generated for respective divided electrodes, to be variable. CONSTITUTION:Incoming neutral particles (n) are ionized by neutral gas in a stripping cell 3 through the exchange of electric charge so that they are forwarded to a deflection electric magnet 4 as a incoming ion. In the deflection electric magnet 4, a magnetic field H is imposed onto the incoming ions so that Larmer revolution of the incoming ions are thereby made. The incoming ions wherein the Larmer revolution occurs, come in a divided type electrostatic deflection plate 10. Voltage in response to the energy of each incoming ion, is applied to each electrode 11-1 through 11-5 of the divided type electrostatic deflection plate 10. This permits an electrostatic field wherein no orbital dislocation takes place of the incoming ion owing to the leakage of electric fields, to be generated in each divided electrode 11-5 through 11-1. This constitution therefore allows the incoming ions to be displaced by the electric fields to the direction of the axis (z) of coordinates, the displacement Z corresponds to the value of the mass of each neutral particle, thereby making it possible to detect the mass and energy of the neutral particle.

Abstract: PURPOSE:To partially reinforce a casting by preliminarily embedding a reinforcing material having a low m. p. into part of an expendable pattern then executing casting by using such pattern. CONSTITUTION:A foaming agent is impregnated into polystyrene and is heated to foam in a metallic mold. The expendable pattern 10 having a runner 12 and a sprue 13 is manufactured by such method. Plural pieces of tin (Sn) wires 14 are preliminarily embedded at prescribed intervals into the part C of the pattern 10 corresponding to the desired part of the casting. A molten metal adjusted in components to meet the characteristics of the casting in the position corresponding to D of the pattern 10 is then poured into the mold through the sprue 13. The molten metal flowing into the part C melts the wires 14 and is replaced with the pattern 10. The structure having much pearlite is formed in the part C of the product and the structure having much ferrite which does not receive the influence of tin is formed in the part D by the above- mentioned method. The casting is thus partially reinforced.
