Title: Sealed electric compressor
Inventor: TANAKA YASUHIKO
IPC: G11B11/105
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To retain and improve the performance of a compressor while improving the performance of a muffler by opening via a branch pipe a sealed small chamber for taking in/out a part of suction gas, on the way of a reed valve for opening/closing an inlet hole and a pipe line extended from the inlet hole to a suction muffler. SOLUTION: A compression unit 5 in which a compression element 3 and a motor are integrated in its upper and lower parts, is elastically supported by a spring 6 in the sealed case 2 of a sealed electric compressor 1. A branch pipe is arranged by being branched away from a pipe line 18, and a sealed small chamber is connected the terminal thereof. In a suction process, when a reed valve 15 is opened, refrigerant gas is led to flow into a cylinder by being passed from a suction muffler 17 through the pipe line 18. Next, when a piston 12 is lifted and a compression process is set in, the reed valve 15 is closed so that gas in the pipe line 18 is rapidly dammed, passed through the branch pipe, and filled into the sealed small chamber. Therefore, the upstream flow of gas in the pipe line may not be stopped, and gas in the sealed small chamber is imediately led to flow into the pipe line.

Title: Stepping motor and its manufacture
Inventor: YAMAMURA YOSHIYA
IPC: H02K37/14
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To provide a stepping motor which can curtail the manhour in molding of parts, and besides can be assembled easily and with high accuracy, and can reduce the manufacture cost as far as possible, and its manufacture. SOLUTION: It is so arranged that an R shape does not arise at the junction between a curling ring yoke 26b and a flange plate 32 by welding a flange plate 32 to the lower brim of a curling yoke 26, made by curling a striped- shaped sheet metal roughly into the shape of a ring, thereby forming a casing 20 without performing the drawing, thus the processing to escape this R-shaped part is made needless. For a motor component to be accommodated in the curling yoke 26, the upper outer brim of the stator 24 is fixed to the top brim of the curling yoke 26, thereby being fixed and retained.

IPC: B65D35/00
Filed: 1991-01-29
Abstract: PURPOSE:To preserve a granular agent stably for a long period of time without generating the reduction of a content due to decomposition and evaporation of an effective component or solidification of the granular substance even when the granular substance contains a chemical compound which is unstable to water or oxidation by putting the granular substance in a container of an aluminum single layer tube or aluminum laminated tube. CONSTITUTION:A granular state agent is put in a tube container made of aluminum or aluminum laminate. In the case of aluminum tube, the thickness of the aluminum shall have strength which does not rupture easily, and on the inner surface, a thermoplastic adhesive is coated in order to heat-seal the bottom part after a granular agent is filled. In the case of aluminum laminate tube, since the tube strength is reinforced by the laminated resin film, etc., the thickness of the aluminum is made to be equivalent to a thin aluminum foil which is enough to prevent moisture, air and effective component from permeating, and one with thickness of approximate 15mum is used. Also, for a shoulder part A of the tube, a resin of which permeability for moisture, air and effective component is small such as high density polyethylene, etc., is used.

Title: Gradation display system
Inventor: MOBARA YASUHISA
IPC: G06T5/00
Filed: 1987-01-19
Abstract: PURPOSE:To increase the number of display gradations without receiving any limit of image resolution ratio between an input and output by using a means which defines several picture elements of a picture as one block and expanding the picture into a density pattern for each block for display of gradation. CONSTITUTION:Picture data having gradations and inputted from an input device 1 is converted into digital gradation signals of 4 bits, for example, for each picture element by an A/D converter 2. These gradation signals are stored in a picture memory 3. In case multilevel data stored in the memory 3 is intermediately displayed in a binary values of black and white, only 16 gradations (4X4) are shown as long as the output side has (4X4) image resolution, for example, with respect to the image resolution of the input side. In this case, four picture elements which approximate the multilevel data on the memory 3 are put in one group to show 64 gradations (8X8). Thus it is possible to increase the number of gradations to be displayed without receiving any limit of the image resolution ratio between the input and the output.

Title: Terminal network controller
Inventor: TANABE MINORU
IPC: H04L29/00
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To reduce a power supply load by providing a switch to a MODEM and a DTMF section so as to allow a power supply of a telephone line to activate an off-hook detection circuit. SOLUTION: In the case of call communication by a terminal network controller, a control section 9 closes a line interface section 1 to set a 3rd switch means 7 ON and then to set a 1st switch means 4 ON. A control section 9 allows a DTMF processing means 3 to make dialing of a telephone number of a notice destination and to make line connection to the communication destination and turns off the 1st switch means 4 and turns off a 2nd switch means 6. Then transmission data are modulated by a MODEM processing means 5 and sent to a telephone line 2. Furthermore, a reply signal received from a center equipment or the like is demodulated by a MODEM processing means 5 and the control section 9 makes a reception processing. When data communication is finished, the control section 9 turns off the 3rd switch means 7 and a MODEM LSI 8 reaches a standby state.

IPC: B65G17/38
Filed: 2012-01-11
Abstract: The invention relates to mechanical engineering, in particular to the dismountable hauling chains of conveyers. Such chains can be used in various branches of agriculture and industry for provision operation of continuous scrapper conveyors transporting various loads (for example, dusty, fine grain, hot, abrasive loads etc.) in horizontal, inclined or vertical directions. The proposed technical solution laminated chain is characterized by construction of chain axes and plates. The aim of the invention is to increase service life of flat-link chains by using chain with one-sided turn of its links. The ends of axes are formed with concave working planes, but the figurative holes of both plates are formed asymmetric and are offset radially relative to the axis of symmetry of the plates. Such chain construction allows to reduce the dimensions and metal consumption of chain links and eliminates excess movement of its pivots.

Abstract: The present invention teaches that relatively low levels of serum progesterone, 1 to 6 ng/ml, may be used to prevent endometrial cancer. The vaginal delivery of progesterone using a cross-linked polycarboxylic polymer produces this low serum progesterone level while also providing the full secretory transformation of the endometrium, indicating the efficacy of the progesterone. Such low levels of serum progesterone will decrease the risk of breast cancer experienced by women undergoing hormone replacement therapy ("HRT") and minimize the potential of other undesirable progesterone associated side effects.
