Title: Display device
Inventor: KAJIWARA AKIRA
IPC: G02B26/10
Filed: 1989-08-04
Abstract: PURPOSE:To reduce the cost of the device and to allow the easy execution of maintenance by driving one horizontal scanning device to scan a laser beam in a horizontal direction and driving the other perpendicular scanning device to scan the laser beam in a perpendicular direction, thereby displaying images on a screen. CONSTITUTION:The laser beam generated from a laser light source 11 is reflected to the horizontal direction reflecting mirror 12 rotating in the horizontal direction to plot images in the horizontal direction on the screen 14. The laser beam reflected by the horizontal direction reflecting mirror 12 is then reflected by the perpendicular direction reflecting mirror 13 rotating in the perpendicular direction and falls onto the screen 14 to form a light spot. The laser beam plotted in the horizontal direction is plotted in the perpendicular direction by the perpendicular direction reflecting mirror 13 at this time. Since the electron beam generator is constituted of the laser light source, the display device is inexpensively constituted and the display device having high accuracy is obtd.

Title: Optical recorded information reading device
Inventor: NAKADA JUNICHI
IPC: G11B7/00
Filed: 1986-08-29
Abstract: PURPOSE:To obtain a reading RF signal having the frequency characteristics approximate to a fixed amplitude with sharp rise and fall, by securing coincidence of phases between the output signals of a pair of photodetecting elements which are set adjacent to each other in the direction parallel to the tangent of a recording track of a disk and then adding both output signals together to obtain the reading RF signal. CONSTITUTION:The photodetecting face of a 4-split photodetecting element is divided into four pieces by a dividing line 2 set in the direction parallel to the tangent of a recording track of a disk and another dividing line 3 orthogonal to the line 2. The outputs of photodetecting elements 1a and 1b and 1b and 1c that received the reflected light from a recording face are added with each other by adders 4 and 5 respectively. A phase difference detecting circuit 9 detects the difference of phases between both adders 4 and 5 and switches a changeover switch 6 to the side (b) to secure coincidence of outputs between both adders 4 in terms of the phase via delay circuit 7. The outputs of both adders 4 and 5 are added together by an adder 8 and therefore a reading RF signal is obtained. This RF signal has a waveform which is free from rise and fall distortions, the reduction of amplitude, etc.

Title: Surface reforming of metallic material by underwater high-speed two-phase jet
Inventor: SATOU KAZUNORI
IPC: B23P17/00
Filed: 1992-07-30
Abstract: PURPOSE:To reform the surface of a metallic material where a tensile stress resides so as to generate a contraction stress, by blowing in the air current near the upstream side of an exhaust nozzle to inject an under-water high pressure jet, and injecting a mixture of a liquid and a gas. CONSTITUTION:By reducing the diameter 3a of a nozzle to inject a high pressure water 8 under the water, and blowing in a compressed air 9 in the form of minute bubbles at the upstream of the nozzle, the generation of the cavitation of the water jet injected from the nozzle is expedited by a strong disturbing operation by the blown-in bubbles. That is, by utilizing the complex breakdown pressure generated by the blown-in bubbles and the cavitation (the blown-in bubbles exercise the role of cushioning to moderate the shock pressure of the temperature), the residual stress on the surface of an under-water is structure material is converted from the tensile stress side to the contraction stress side.

Abstract: PURPOSE:To well correct aberration with a smaller number of lenses by providing the IVth group contg. a lens which has a positive refracting power and at least one face of which is an aspherical face and the Ist group which executes focusing as the entire part or a part thereof moves along the optical axis. CONSTITUTION:Zooming is executed as the IInd group 2 and the IIIrd group 3 move simultaneously along the optical axis while maintaining the image plane in a specified position. The focusing is executed as the entire part or a part of the Vth group 5 moves along the optical axis. A stop is disposed in proximity to the IVth group 4 on the object side or image plane side of the IVth group 4. The rays arriving at the center of the image plane pass the relatively high position of the lens of the IVth group 4 in this way.

Title: Actuator
Inventor: TODOROKI TSUNEHIKO
IPC: F24F13/14
Filed: 1985-09-17
Abstract: PURPOSE:To make it possible to instantaneously and positively carry out the changeover between a cool heat source and a hot heat source and to carry out an alternating operation such as an air flow direction changing plate by combining a snap operation with the operation of a shape memory alloy (SMA), and providing a time delay to lever operation and passage switching operation. CONSTITUTION:When an SMA 20 is cooled with a cool heat source, it is elongated by a bias spring 21 and a lever begins to move. However, a passage switching plate 16 for idly moving a lever end engaging portion 17 in a slide groove 18, does not move. When the lever further moves and reaches a line connecting a fulcrum 14 to an offset point 22, the end engaging portion 17 is at a terminal point of the idle movement, the snapping operation of a snapping operation acts and, at the same time, the lever moves the passage changeover plate 16, closing a cool heat source passage 11 and opening a hot heat source passage 12. Since the SMA 20 is exposed to the hot heat source, it overcomes the force exerted by the bias spring and begins to move, moving the lever 15, closing the hot heat source with an action reverse to the above described action and opening the cool heat source passage. The downstream space is exposed alternately to the hot heat source and the cool heat source and makes it possible to carry out the alternating action of the lever.
