Title: Optical device and image forming device
Inventor: YAMAGUCHI MASAO
IPC: G02B13/00
Filed: 1997-08-14
Abstract: PROBLEM TO BE SOLVED: To improve picture quality by converging light beams deflected by a deflecting means so as to scan a prescribed screen at a constant speed and specifying the specified conditional expression. SOLUTION: A finite lens unit is formed by holding a semiconductor laser element, a finite focal lens and a diaphragm intergally. Then, this optical device satisfies conditional expressions I and II. In the expressions, f is the focal length of the finite focal lens, LG1 is the distance between the semiconductor laser and the finite focal lens, n is the refractive index of the finite focal lens, αG, αU are linear expasion coefficients of the finite focal lens and the holder, λis the oscillation wavelength of the semiconductor laser, Km, Ks are longitudinal magnifications of the main scanning direction and the subscanning direction of the whole of an optical system and ωm , ωs are beam diameters of the main scanning direction and the subscanning direction of the whole of the optical system.  Thus, even when an ambient fluctuation is generated, however the focal length of the finite focal lens is fluctuated, the distance between the semiconductor laser element and the finite focal lens is changed by the thermal expansion of the holder in which the laser element and the finite focal lens are integrally held to cancel the change of the focal length.

Title: Injection molding process of both surfaces molding and injection molding machine
Inventor: IWAHASHI TETSUO
IPC: B29C45/32
Filed: 1989-08-25
Abstract: PURPOSE:To remove the necessity of providing a through hole in the center of a mold by a method in which plastic material is simultaneously injected into the molds respectively positioned between a stationary platen and a movable platen on both surfaces of the stationary platen, and is simultaneously molded with the molds at both surfaces. CONSTITUTION:Left and right movable platens 14 are respectively moved to a stationary platen 12 with a mold-opening and closing cylinder. Movable molds 15 are closely fixed to stationary molds 13 by a mold-clamping cylinder. Plastic material is injected into left and right cavities 24 from an injection device 16 through a manifold 20, and is molded simultaneously with left and right molds. Thus, since the material is simultaneously molded with left and right both surfaces, the molding with high productivity is achieved. Since the through hole for an extension nozzle is not formed on the molds in the injection molding machine 10, a cavity 24 is freely arranged, and the diversification of the molda ble shape of a molded object is achieved. For instance, a large molded object may be molded by using the almost whole surfaces of the molds 22.

Title: Rain sensor
Inventor: ADACHI SHINJI
IPC: G01N27/22
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a rain sensor which hardly deteriorates by arranging a pair of comb-shaped electrodes 1a and 1b on the rear surface of a ceramic substrate 2 having a detecting surface on its front side in a mutually facing state and detecting water drops adhering to the detecting surface of the sensor from the change of the capacitance between both electrodes. SOLUTION: The rain sensor is constituted by forming the surface of a ceramic substrate 2 as a detecting surface 3 and forming comb-shaped electrodes 1a and 1b on the rear surface of the substrate 2 in a mutually facing state by screen printing. The substrate 2 closes the top opening of a thin box 4 and a detecting circuit 5 is provided on the bottom of the box 4, with the input terminal section of the circuit 5 being connected to the electrodes 1a and 1b. The circuit 5 is provided with a CR oscillation circuit and outputs the change of the capacitance between the electrodes 1 and 1b when water drops 6 adhere to the detecting surface 3 after converting the change into the change of the oscillation frequency of the oscillation circuit. Thus the circuit detects the change of the oscillation frequency and outputs rainfall signals by issuing alarms, turning on red lamps, etc.  Since the detecting surface 3 has an excellent deterioration resistance and the electrodes 1a and 1b do not receive the water drops 6 directly and have excellent deterioration resistances, the rain sensor can be maintained easily.
