Title: Excavation device
Inventor: MATSUI NOBUHIKO
IPC: E21B4/14
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To prevent breakage of an inner pipe due to vibration of an adapter by a method wherein air outlet and inlet are formed in the outer periphery of an adapter head, a piston chamber is formed in a central part, and an air chamber is formed on the piston head side during working, in an excavating device provided with an outer pipe having an outer bit, and an inner pipe having a downhole hammer. SOLUTION: Pressurized air supplied through an air inlet 11 passes through a first passage 13, a first air passage 9, a first air chamber 8a, and an inner pipe 30 to operate a downhole hammer. Further, a rotation force from a drive source is transmitted to an outer pipe 31 through an adapter head 2 and an adapter 4, and transmitted from a piston rod 21 to an inner pipe 30. However, a distance δ by pressurized air is formed in a first air chamber 8a. Since a second passage 10 has size enough to discharge a leakage content of a piston 20, the vibration force in an axial direction of an adapter head 2 is not transmitted to the inner pipe 30. Thus, since vibration does not interfere, the damage of the inner pipe 30 is prevented from occurring.

Abstract: PURPOSE:To realize a compact, light-weight and simple structure of a recording or reproducing device, by detecting the revolving speed of a guide roll which touches a recording carrier and is turned when the recording carrier is running, and controlling a reel motor. CONSTITUTION:A projected part of a loading ring 5 moves a slide plate 12 upward with the revolution of the ring 5, and therefore an engagement pin 12a implanted to the plate 12 engages a roll arm 11 to turn it. A guide roll 10 set at an end of the arm 11 goes into a tape lead-out route by the revolution of the arm 11. Thus a tape T touches the roll 10 over 180 deg.. When the roll 10 is revolved, the slit of a frequency generating disk 18 turns within a photocoupler 19 to produce a signal of a frequency corresponding to the tape traveling speed. This signal detects the traveling speed of the tape T, and also controls the speed of a reel motor.

Title: Signal testing device
Inventor: NAKAGAWA HIDETO
IPC: H04Q9/14
Filed: 1979-11-29
Abstract: PURPOSE:To improve the reliability of the  test result of a control required signal and to reduce a time lag until the result is obtained by making AND for mutually complementary party-side signals for the reception and test of the control-required signal. CONSTITUTION:Since control-required signals are sent onto transmission circuits 1a and 2a normally, there is no output to controller 8. Once control-required signals are outputted to transmission circuits 1a and 2s, receivers 9 and 10 hold signals 9a and 10a high and signals 9b and 10b low to open AND gates 12 and 13. If a code erro occurs on transmission circuit 1a and the control-required signals are not detected, receiver 9 holds signal 9a low and signal 9b high, so that neither AND gate 12 nor 13 will be opened. Therefore, the reliability of the result can be improved and the control-required signal is never outputted being delayed.

Title: Thread information collection method and recording medium recorded with thread information collection program
Inventor: KATAYAMA TORU
IPC: G06F9/46
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To easily collect the information on the thread switching operations by collecting the information on the thread states via one or both of the calling of a function and its return. SOLUTION: A function B is called at time T1 for a function A, and a thread information collection program 12 is called. When the next function X is called, a function Y is called at time T2 and then the program 12 is called. In such cases, the program 12 acquires a thread ID to identify the thread at time T2. Then the thread ID acquired at time T2 is compared with the thread ID stored at time T1. Thus, it's decided whether the threads are switched or not. If the threads are switched, this fact is recorded as the trace data.

Title: Semiconductor laser device and its preparation
Inventor: SUGINO TAKASHI
IPC: H01S5/00
Filed: 1978-12-18
Abstract: PURPOSE: To provide an active layer with rib type photo-waveguide passage structure, by forming the stair-like difference in a stage onto a surface of a substrate, and by successively growing a clad layer, the active layer, a clad layer and an ohmic electrode forming layer on that.  
     CONSTITUTION: When the crystals of a clad layer 9, 11, an active layer 10, 11 and an ohmic electrode forming layer 12 are continuously grown on a substrate 8 to which difference in a stage T is made up, the speed of growth of the difference portion in the stage T becomes faster than the speed of growth of a flat portion in the initial stage of growth. Since the characteristic is particularly remarkable about the growth of the clad layer 9, the thickness of the layer 9 is sufficient in order to prevent the absorption of light at a portion just above the difference portion in the stage T. In portions except the portion, light radiated in the active layer 10 can be absorbed to the substrate 8 by leaking all of the light to the substrate 8. The active layer 10 has two bends 17, 18. Thus, the thickness of the active region 10 becomes thicker than the flat portion only by 10∼20%, and a rib type photo-waveguide passage can be obtained.
