Title: Bobbin thread breakage-detecting method for sewing machine
Inventor: TANAKA HIROSHI
IPC: D05B51/00
Filed: 1993-06-28
Abstract: PURPOSE:To stop a sewing machine automatically by indirectly judging the breakage of a bobbin thread by measuring the consumption quantity of a needle thread at every specified period of time when detecting the breakage of the bobbin thread in a sewing process by a sewing machine. CONSTITUTION:A bobbin thread 2 is put in a loop of a needle thread 1, which is formed at the bottom dead center of a sewing machine needle, and a sewing motion is advanced, and the needle thread 1 is fed and consumed by an entanglement with the bobbin thread 2. At this time, if a breakage of the bobbin thread 2 generates, there is no entanglement of the needle thread 1 with the bobbin thread 2, and the needle thread 1 linearly runs on the surface of a cloth in the cloth advancing direction. For this reason, the consumption quantity of the needle thread 1 becomes smaller by a portion for the entanglement with the bobbin thread 2, and a difference in the consumption quantity of the needle thread 1 per a unit period of time is generated before and after a breakage of the bobbin thread 2. By utilizing this principle, the generation of a breakage of the bobbin thread 2 can be indirectly detected by monitoring the behavior of the needle thread 1 only. Therefore, by this detection, a sewing machine device can automatically be stopped.

Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To enable a tester to easily observe an eye to be tested by making the eye to be tested to see a distant view outside. SOLUTION: A luminous flux from a vision fixation light source 28 is reflected by a mirror part 20b of a light split member and passed through light splitting members 14, 1, etc., and made thinner at a pupil (P) then projected onto an eye to be tested. The eye (E) to be tested can view a light source 28 for vision fixation overlapped on a distant view outside through a light splitting member 1 regardless of the visibility, and then the visual axis coincides with the measurement light axis O1. The reflected light from the anterior part of the eye (E) to be tested by a light source for an anterior part lighting around the light axis O1 reaches a tester's eye (e) through the light splitting members 1, 14, and a unit, etc., and the tester's eye (e) observes the eye (E) from the diagonally directing light axis O4.  Thus, the tester can easily observe the distant view eye (E) to be tested without interruption in the front sight field of the eye (E) to be tested by the tester's eye (e).

Filed: 1992-08-10
Abstract: PURPOSE:To improve the system throughput of the multi-access system of a token passing system and to simplify address processing. CONSTITUTION:Normally, four token packets 5-8 rotate on a loop. A node 3 for which a transmission request is generated sets a first light wave length selection switch 10 so that the wave length lambda1 of a token corresponding to the node 1 of the transmission destination is pulled inside the node and the rotated token 5 is pulled inside the present node. Then, the output wave length of an E/O 14 provided with the light source of a variable wave length is set at the address wave length lambda5 of the transmission destination node 1 and a data packet 9 is transmitted from the second input terminal of the first light wave length selection switch 10 by the wave length lambda5 corresponding to the transmission destination node 1. After completing the transmission of the data packet 9, the output wave length of the light source of the variable wave length is switched to the token wave length lambda1 for the node 1 and the token packet 5 is transmitted.

Title: Manufacture of semiconductor device
Inventor: SAITO SHUICHI
IPC: H01L21/322
Filed: 1991-08-26
Abstract: PURPOSE:To prevent the trouble of the increase of leakage currents within a certain specified range of the dosage of implantation when ions having high energy are implanted. CONSTITUTION:The generation of a defect generated at the time of implantation, oxygen in a substrate 1 and a secondary defect after heat treatment is related to the increase of leakage currents. Consequently, boron is implanted and a B<+> implanted layer 6 is formed, and silicon is implanted at the same position as said boron and an Si<+> implanted layer 7 is formed. That is, the Si<+> implanted layer 7 is formed into the B<+> implanted layer 6. Accordingly, defects are confined in the B<+> implanted layer 6, thus reducing leakage currents within the range of the dosage of all borons. The effect is acquired even when the positions of the generation of the defects are formed in the B<+> implanted layer 6 or at deeper positions or under a field oxide film 5 at that time.

Abstract: PURPOSE:To easily discriminate the life of a photosensitive body by disposing a feed pawl to be periodically oscillated, a rotating body to be rotated in a constant quantity by the oscillation of the pawl and an actuator spirally advanced cooperatively with this constant-quantity rotation on a photosensitive body side. CONSTITUTION:The rotating body 2 is drastically decelerated and rotated at the constant quantity each slightly by the oscillation of the feed pawl 1 which is periodically oscillated in synchronization with the rotation of the photosensitive body 6. The actuator 3 is spirally advanced in an arrow (d) direction when the rotating body 2 is rotated slightly. Namely, the rotating speed of the photosensitive body 6 is extremely lowered and is converted as the moving quantity of the spirally advanced actuator 3. A detecting electrode 4 and an earth electrode are operated by the movement of the actuator 3 to operate a device 9 for displaying the life of the photosensitive body, by which the grounding of the conductive layer of the photosensitive layer 61 of the photosensitive body 6 is interrupted. A user is, therefore, able to easily check the cumulated number of rotation, i.e. life, of the photosensitive body 6.

IPC: F02G1/05
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent the abnormal heating of a heating tube by providing a control device for receiving the signal from a pressure sensor and for opening or closing an open valve and a bypass valve when abnormality occurs so as to control the operating gas pressure inside a Stirling engine at the set value. SOLUTION: When abnormality occurs, a gas supplying line and a gas discharging line of an operating gas circuit are communicated with each other, and an atmospheric air discharging open valve 10 is opened so as to discharge the operating gas of a Stirling engine 1. When the operating gas pressure inside the Stirling engine 1 becomes 0, the Stirling engine 1 is stopped. Operating gas pressure is detected by a pressure sensor 11, and when the operating gas pressure at a constant pressure or less is detected, the open valve 10 and the bypass valve 9 are closed so as to stop the discharge of the operating gas. With this structure, since the operation is performed in the non-load idling condition and the heater tube 15 absorbs the heat so as to lower the temperature, abnormal heating can be prevented.
