Title: Beam conversion device
Inventor: YOSHIFUSA KOJI
IPC: G11B7/135
Filed: 1989-12-28
Abstract: PURPOSE:To realize the miniaturization of a device and the reduction of cost by determining properly the apex angle of a prism and the position of the prism relative to the axis of the incident light of a laser, and simultaneously, providing an antireflection film on a plane of incidence, and shaping a laser beam into a circular shape, and simultaneously, bending it by a prescribed angle. CONSTITUTION:Light from a semiconductor laser element 1 is stood into 90 deg. by the prism 5, and is converged to the reading surface 7 of an optical disk 6 through an objective lens 4. Light flux reflected at the surface 7 returns through the same route, and is diffracted by a hologram diffraction element 8, and enters a light receiving element 9. In this constitution, by making an angle theta1 of incidence from a collimate lens 3 at the prism 5 and an angle theta2 of outgoing to a plane 11 into the prescribed values of about 75 deg. and about 15 deg. respectively, a standing angle can be made into about 90 deg., and simultaneously, the light flux of the element 1 can be shaped from an ellipse to a circle. Further, the antireflection film 13 is provided on the plane 11 so as to suppress reflection loss. Thus, a beam shaping optical system need not be provided, and the miniaturization of the device and the reduction of cost can be attained.

Title: Production of compact carbonaceous plate
Inventor: KAWASAKI AKIYOSHI
IPC: C04B35/52
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To efficiently produce a compact carbonaceous plate having high flexural strength by blending carbonaceous powder with a thermosetting resin to prepare a mixture including a specific quantity of a phenolic resin, by hot- forming the mixture under a pressurized condition at a pressure not lower than a specific pressure value to form a plate and by firing it in a nonoxidative atmosphere to carbonize it. SOLUTION: This compact carbonaceous plate is produced by the dry blending of carbonaceous powder (graphite) with <=10 wt.% phenolic resin having ca. 20 μm particle diameter, by hot-forming the mixture under a pressurized condition at >=50 kgf/cm2 pressure to form a plate and by firing it in a nonoxidative atmosphere to carbonize the thermosetting resin (phenolic resin). When firing, part of the thermosetting resin is thermally decomposed and is volatilized, but the compact state of the carbonaceous plate is retained even after being fired as the content of the thermosetting resin is originally small and therefore the sufficiently compact carbonaceous plate is produced on the first forming and firing. When a metal mold for molding has been grooved, the surface of the carbonaceous plate can be imparted by preferred grooves.

Title: Dozing driving preventing device
Inventor: YAMAURA YOSHIO
IPC: B60H1/24
Filed: 1992-12-25
Abstract: PURPOSE:To prevent a dozing state without discomfort by stitching a valve to the outside air lead-in side when air pressure at the time of detecting traveling for a fixed time in the detected driving state is the threshold value or less, and operating a blower with a shutter closed until the air pressure exceeds the threshold value. CONSTITUTION:A driving state is detected by a driving state detecting means 1, and air pressure in the vehicle interior at the time of detecting traveling for a fixed time in this driving state is detected by an air pressure detecting means 2 and inputted into a control means 8. When the detected air pressure is the threshold value or less, a change-over valve 4 is driven by an actuator 5 to switch to the outside air lead-in side from inside air circulation. A blower 3 is thereby operated, and an air outlet shutter 6 for opening/closing the vent hole of a rear pillar is closed through an actuator. When the air pressure exceeds the threshold value, the blower 3 is stopped. The total quantity of oxygen is thereby increased to prevent driving while dozing without performing unpleasant control such as changing body sensory temperature to a driver or the like.
