Title: Electronic part supplying apparatus
Inventor: OTSUKA RYOJI
IPC: H05K13/04
Filed: 1990-02-09
Abstract: PURPOSE:To make it possible to replace an electronic parts supplier while an electronic parts packaging machine is operated by making it possible to move the specified section of the electronic parts supplier outside the moving range of the head of the packaging machine. CONSTITUTION:The head 1 of an electronic parts packaging machine is located to the predetermined position where the electronic parts of an electronic parts supplier 4 can be sucked by an XY robot 2. The electronic parts are sucked, located to the predetermined position on a printed circuit board 3, and packaged. The electronic parts supplier 4 is divided so as to be removed by the blocks for simultaneous replacement of a plurality of blocks. Each of the blocks of the electronic parts supplier is equipped with an air cylinder, by which the electronic parts supplier is slid by the blocks. When for example the parts in the block B of the electronic parts supplier run out, information from the packaging machine moves the block B of the electronic parts supplier to the outside of the moving range of the head of the packaging machine for replacement of the electronic parts supplier.

Title: Thread delivery device for sewing machine
Inventor: ITO HIDEKAZU
IPC: D05B45/00
Filed: 1990-02-10
Abstract: PURPOSE:To surely perform a sewing operation even when stitch balancing thread tension is set weakly by supplying sewing thread with prescribed length by driving a thread piece with a driving means by a control means when a thread delivery operation from the thread piece by the needle thread take-up of a needle thread take-up mechanism is performed. CONSTITUTION:When a needle bar 3 is descended by the rotation of a sewing machine main spindle 4, the needle thread take-up 11a is also descended in accordance with the above descent, and at this time, the sewing thread 6 for stitch formation is supplied to a sewing needle 2 side. Following that the sewing needle 2 is pierced through cloth and one stitch is formed on the cloth, the needle bar 3 is ascended, and the needle thread take-up 11a is also ascended accordingly. At this time, when a detection signal is detected by a rotary position detector 5 prior to the ascent of the needle thread take-up 11a, a driving motor 9 is driven, which turns the thread piece 7 in a thread delivery direction, and the sewing thread 6 with prescribed length can be delivered. Therefore, it is possible to prevent the rolling frictional force of the thread piece 7, etc., from functioning of thread passing resistance even when the setting of passing resistance by a stitch balancing thread tension pan 10 is set weakly, and to always set appropriate stitch balancing thread tension, which forms the stitch uniformly and regularly.

Title: Image forming device
Inventor: YASHIKI YUUICHI
IPC: G03G15/04
Filed: 1982-03-01
Abstract: PURPOSE:To prevent electrical sticking of a variety of dust, etc. and the corrosion on  the surface of image sensing elements, by forming protective layers consisting of  phenolic resins on at least one of the light incident end face and light exit end face of  an image forming optical system using a small diameter array of a short focus. CONSTITUTION:The end face of an image forming optical system 3 using a small image  forming element array 1 of a short focus is easy to pick up dust as said surface is  charged electrostatically to an extremely high potential by corona discharge. The element surface 1 is also corroded by the corrosive materials, such as nitric acid, formed  by the ozone generared by corona discharge, ionized gaseous molecules, steam, etc., on  account of which a considerable decrease in the performance of the optical system  results. The protective layers consisting of phenolic resins formed on the three end  faces of the image forming optical system are extremely hard, are highly mechanically  durable, have relatively low electrical resistance, and are extremely stable to corrosive  materials such as acids and alkalis. Therefore, said protective layers decrease the generation of electric lines of force having a dust collecting effect, and prevent the corrosion on the surfaces of the image forming elements occuring in exposure to the  corrosive chemical seeds generated from corona electrifiers, etc.

Abstract: PURPOSE:To form an ideal seal line on the sides of both rotors at the time of operation and improve compression efficiency by obtaining a tooth form including a quantity of interference caused by the thermal expansion of both female and male rotors at the time of operation and determining the tooth forms of said both rotors at the normal temperature. CONSTITUTION:Female and male rotors F, M which are arranged in such a way that the gap between tooth surfaces are zero at the normal temperature, are assumed, while the quantity of interference epsilon1-epsilon7 at each tooth form point in the axial plane of rotation of both rotors F, M caused by thermal expansion at the time of operation, are obtained. And, the tooth form of the rotor F at the normal temperature as shown by the solid line is corrected to be a tooth form as shown by the broken line so as to absorb the quantity of interference. Also, the quantity of interference epsilon1-epsilon7 includes the actual quantity of interference plus a gap for safety and a gap for coating, between tooth surfaces as mentioned below, i.e., when obtaining the correction of the female rotor F, it is necessary to give consideration to a gap for safety between tooth surfaces of rotors at the time of operation and a gap for coating. Thereby, an ideal seal line can be formed between both rotors F, M at the time of operation, improving compression efficiency.

Abstract: PURPOSE:To improve the flowout efficiency of combustion gas with a simple construction by constituting an exhaust valve from a main exhaust valve provided with a combustion gas path and an auxiliary exhaust valve inserted relatively slidably in the main exhuast valve to open and close the combustion path. CONSTITUTION:An auxiliary exhaust valve 2 is relatively slidably inserted in a main exhaust valve 1 formed with a combustion gas path 3 for affording communication between the bevelled surface and end face of the valve. Thus, when the valve is closed, the auxiliary and main exhaust valves 2, 1 abut respectively against a valve seat 1a of the main exhaust valve 1 and a valve seat 4 to interrupt the flow of gas. On the other hand when the valve is opened, the respective main and auxiliary exhaust valves 1, 2 are both opened. As the opening area of the valve is increased, a gas outlet is also produced near the center of the main exhaust valve 1 so that the efficiency of flowout of combustion gas is improved. Thus, the efficiency of scavenging is improved and the rate of fuel consumption can be reduced.
