Title: Zigzag sewing mechanism of embroidery sewing machine
Inventor: TAJIMA IKUO
IPC: D05B35/08
Filed: 1990-08-16
Abstract: PURPOSE:To reduce production cost and driven load and improve accuracy by transmitting the vertical motion of a lever driving member through only a connecting member to a zigzag lever to rotate the connecting member together with a rotary bushing about its own axis relatively to the lever driving member. CONSTITUTION:While a connecting member 96 is fitted in a groove 74 formed vertically relative to the outer peripheral surface of a rotary bushing 70, the connecting member is engaged with a lever driving member 92 not to move vertically. When a drive shaft 108 pivotably reciprocates together with a driving lever 109, a lever guide shaft 100 moves vertically so that the lever driving member 92 together with the connecting member 96 moves vertically along the outer periphery of the rotary bushing 70. Thus, a zigzag lever 76 pivots (swings zigzag) about the axis of a lever pin 78. Thus, the number of parts of a zigzag sewing mechanism can be reduced and the accuracy therein can be improved while the production cost and a driven load for the zigzag sewing motion are reduced.

Title: Deflection yoke
Inventor: KOIZUMI HIROHISA
IPC: H01J29/82
Filed: 1990-08-16
Abstract: PURPOSE:To ensure the action of a uniform clamping force as a whole by forming a projection on the inner side of a deflection yoke clamping band in the vicinity of a section where a clamping force is weak. CONSTITUTION:A clamping band 5 has a section for setting a clamping screw 6, and four inner projections 7 at an angle of approximately 45 deg.C with a straight line A between the aforesaid section and the center of the band 5. When the screw 6 is tightened, the projections 7 give a strong clamping force F' to a deflection yoke clamping section 4 and an image receiving tube neck 3. This clamping force F' can be made equivalent to a clamping force at points C and D by pertinently setting the extent of the projections 7. Consequently, it is possible to make uniform a clamping force applied from the clamping band 5 to the image receiving tube neck 3 via the deflection yoke clamping section 4.

Abstract: PURPOSE:To prevent a breakage caused by freezing in a heating heat exchanger by a method wherein a fan motor is operated with forced air under a control of a timer circuit, a cooling heat exchanger temperature sensor and a microcomputer if a temperature of the cooling heat exchanger is decreased even if an indoor device is being stopped in its operation. CONSTITUTION:If it is assumed that a stopping instruction is sent to a cooling outdoor device and a cooling heat exchanger 22 is kept at a temperature of 0 deg.C irrespective of elapsing of a specified period of time, a microcomputer 5 judges that a cooling outdoor device 26 shows leakage in solenoid valves 30-a and 30-b in a freezing circuit or a control circuit at the cooling outdoor device 26 shows a runaway and a fan motor 9 is stopped, thereby the refrigerant is flowed and abnormally cooled. It further outputs signals to a fan motor circuit 6 and a display lamp control circuit 12. Irrespective of the fact that the outdoor device 21 is stopped, a fan motor 24 is operated with strong air, an abnormal cooling of the cooling heat exchanger is prevented through a heat exchanging operation with indoor air, thereby a breakage of the adjoining heating heat exchanger 23 caused by its freezing is prevented and at the same time an operation display lamp 13 is illuminated to display the abnormal state.

Title: Circuit supervisory unit
Inventor: TAKAI HITOSHI
IPC: H04N7/16
Filed: 1985-09-30
Abstract: PURPOSE:To accurately grasp the occurrence of a failure at each home terminal equip ment and to discriminate the place of the failure by providing a means that decides in which branch of a transmission path the failure has occurred to a supervisory terminal equipment when a failure detection signal from a tap-off having a failure detector that detects the abnormality of a down transmission signal is received. CONSTITUTION:Each of tap-offs 50-58 is equipped with the failure detector that detects the abnormality of the down transmission signal in its inside. When the failure is generated at, for example,a branch 32 out of branches 30-49, (the occurrence of the failure at nodes 71-75 is considered as the failure at the branch to which the node is connected) the failure is detected at tap-offs 54-57 connected to the branch 32. When the failure is detected, the tap-off transfers the failure detection signal of the tap-off to the supervisory terminal of a head end 25 as an up transmission signal. The failure detection signal is demodulated at a reception demodulation circuit 17 in the supervisory terminal, being sent to a control circuit 20. At a storage device 26, a corresponding table between each branch of the transmission paths and the terminal equipment that is connected to each branch and is equipped with the failure detector is stored, and the control circuit 20 discriminates the branch where the failure is generated while using the corresponding table.

CONSTITUTION:A flat plate-like thick and porous material is used to constitute the duct and is formed into a tubular shape by fasteners 2. One end of the duct 1 is connected to the air sending port of an air-conditioning equipment directly or indirectly and the other end thereof is closed. The duct is made of the porous material such as cotton cloth, wire mesh, a film-like material or the like, therefore, respective fine holes on the whole surface of side wall of the duct 1 become blow-off ports and air of slow speed is blown off therefrom whereby the air conditioning of an objective room may be effected. When the duct 1 is utilized for the transfer of air-conditioning air, the duct is provided with a film or film of coating 4 of rubber, synthetic resin or the like on the inside of the duct 1. The ventilation from the side wall of the duct 1 may be controlled by making the film or the film of coating 4 with proper size and configuration. In such ventilating method effected by the air leaking duct, the side wall of the duct 1 becomes blow-off ports and big amount of air, having very slow blow-off speed, may be blown off into a room uniformly in accordance with the purpose of the air conditioning.

Title: Optical pickup
Inventor: ITONAGA MAKOTO
IPC: G11B7/135
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To suit it to recording/reproducing of optical disks with different thickness by moving a position of an optical element focusing light outgoing from a semiconductor laser element in the optical axial direction. SOLUTION: When the optical disk D of a DVD is recorded/reproduced, a distance between the semiconductor laser element 1 and a collimate lens 4 is set large, and its outgoing light is made so as to become parallel rays of light. This outgoing light is focused on the recording surface of the optical disk D by an objective lens 5. The reflection light is returned inversely on an optical path to be made incident on a photodetector 7. In the case of a CD, the collimate lens 4 is brought more close to the semiconductor laser element 1 side being a light source by a prescribed distance L1 than the case of the DVD. Thus, the light outgoing from the second surface 4B of the lens 4 is converted into the diffused light. The luminous flux size of the diffused light is set so as to become smaller than the case of the DVD.

Abstract: PROBLEM TO BE SOLVED: To enhance the lifetime of an element by providing irregularities on the interface between a negative electrode and an n-type contact layer, thereby lowering the forward voltage and reducing generation of heat. SOLUTION: An n-type contact layer 11, an n-type clad layer 12, an active layer 13, a p-type clad layer 14 and a p-type contact layer 15 are formed sequentially on a substrate 10, thus constituting a double heterostructure.

An insulation layer 30 is formed between the positive electrode 20 and the negative electrode 22. Since irregularities are provided on the surface of the n-type contact layer 11, contact area between the negative electrode 22 and the n-type contact layer 11 is increased, and the resistance is decreased thus lowering the forward voltage of the element.
