Title: Semiconductor laser device
Inventor: SHIMIZU YUUICHI
IPC: H01S5/00
Filed: 1983-06-29
Abstract: PURPOSE:To perform a stable oscillation with sufficient light output in practice by setting the reflectivity of two resonator ends to 0.45 or higher and 0.80 or lower. CONSTITUTION:The reflectivity of a light in an oscillating wavelength of its laser at two resonator ends are set to 0.45 or higher and 0.80 or lower. Since the reflectivity of the oscillating length of the resonator end of a semiconductor laser is sufficiently higher by approx. 0.3 of the case of the cleavage surface of the semiconductor crystal of laser medium in such a structure, the ratio of the returning light of the light itself into the resonator is decreased. Further, since the reflectivity of the resonator end is sufficiently high, the light energy stored therein is high, and the influence by the light incident from the exterior is less, thereby obtaining stable oscillated state.

Title: Non-contact type ic card
Inventor: MATSUKAWA KOICHI
IPC: G06K19/07
Filed: 1993-04-21
Abstract: PURPOSE:To provide a non-contact type IC card which can reduce power consumption in a simple circuit constitution by using a processing circuit which performs the prescribed arithmetic processing when a switch circuit controlled by a timer circuit is kept in ON state. CONSTITUTION:A battery 11 always energizes a timer circuit 12 and a memory 10d. The circuit 12 functions to transmit the output signals to keep a switch circuit 13 in ON state for a period between 6:00 and 20:00 in a day. Then, the circuit 13 is kept in OFF state in other time bands of the day. A processing circuit 10 receives the supply of power from the battery 11 in the ON state of the circuit 13, and an IC card performs the prescribed ticket examination processing in response to the polling received from the main body of an automatic ticket examining machine. Because no power is supplied to the circuit 10 in the OFF state of the circuit 13, the consumption of the battery 11 is suppressed so that the service life of the battery 11, i.e., a card main body C' can be increased.

Abstract: PURPOSE:To correct a tool-position of a cutting tool with high accuracy by allowing a measuring device capable of longitudinal positioning of an optical outer diameter measuring device and a tool post to be connected and disconnected while a lathe machines a work. CONSTITUTION:NC device 40 commands a slide rest 7 to travel and an optical outer diameter measuring device to automatically travel to a specified position of a work 11. By a travel-completion signal from the NC device, the optical outer diameter measuring device starts the measurement of the work 11 and corrects the tool position of a cutting tool after completion of the measurement. The NC device 40 then commands the optical measuring device to travel to a following measuring position. In this manner, when the required measurement is completed, the slide rest 7 travels in the opposite direction from a headstock 1 to disconnect a connecting rod 35 from a second slide 22 at a specified posi tion, and then moves to a specified position. The outer diameter of the work 11 is thus quickly measured without being in contact with the measuring device with high precision, and the tool-position of the cutting tool can be corrected with high accuracy.

Abstract: PURPOSE:To secure an excellent braking characteristic irrespective of weather or the like as well as to curtail the material cost, by using granular pulverized slags as granular matter preventing the slipping and skidding of a locomotive upon being scattered between a rail and a wheel tread. CONSTITUTION:Granular matter 1 in a sand box 2 installed in a locomotive 9 passes through the inside of a sand scattering pipe 3 and is scattered between a tread 19 of a wheel 4 of the locomotive and a rail 5 by dint of compressed air. And, the scattered granular matter 1 is treaded down by the wheel 4 whereby mutual frictional force between the wheel 4 and the rail 5 is increased. In consequence, the slipping and skidding of the wheel 4 are prevented from occurring, thus tractive force and braking force of the locomotive 9 are all improved. In this case, a pulverized slag is used as the granular matter 1. And, as for the pulverized slag, those made in a blast furnace and a converter are used. According to these slags, an excellent braking characteristic is securable irrespective of weather conditions, while the material cost is sharply reducible as compared with natural sand.
