Patent JP-S6475198-A (JP)
Title: Rotary jig
Inventor: KURIHASHI KATSUMI
IPC: B23K37/04
Filed: 1987-09-14
Abstract: PURPOSE:To facilitate operation and to reduce the manufacturing cost of a rotary jig by preparing an engaging part at each tip end, fitting a pair of supporting legs whose lower ends are pivoted to a base and closing or opening the supporting legs with energizing members. CONSTITUTION:A pair of supporting legs 1 are arranged to clamp a long-sized article W to be worked and an engaging part 8 to each tip end and each lower end to the base 2 are pivoted by pins 3. In addition, a coil spring 4 is arranged as an energizing member between a fixing plate 5 of each leg 1 and the base 2. The supporting leg 1 is put by a spring 4 in an open state to hang up an article W to be worked and the supporting leg 1 is put automatically in a closed state. In this case, a chain 6A is wound up and down by a chain block 6 to turn the article W to be worked. Since the lowermost part of each leg 1 is connected by a pin and each upper end is fixed by engaging, the bending moment acting on the leg 1 reduces. This makes the jig lighter in weight, smaller in size and reduces its manufacturing cost. Further, since the operation is simple, work is facilitated.

Title: Adsorbing material
Inventor: OKAMOTO KUNIO
IPC: B01J20/28
Filed: 1982-12-23
Abstract: PURPOSE:To reduce remarkably desorption of adsorbed gas by forming a coating layer having micropores on the surface of activated carbon, and reducing the sectional area at the inlet of each micropore the activated carbon itself as compared with the sectional area of each inner micropore. CONSTITUTION:A coating layer 3 made of a polymer compd. having no gas absorptivity and micropores opened through the surface is formed on the surface of activated carbon 1. As the polymer compd., ethyl cellulose, acetyl cellulose, nitrocellulose, polyvinyl butyral, etc. are used. The micropores 4 of the coating layer 3 reduces the sectional area of each micropore of the carbon itself at the inlet remarkably as compared with the sectional area of each micropore at the inner deep part, thus reducing remarkably desorption of the gas adsorbed by the carbon 1.

Title: Loading device for paper feed cassette
Inventor: TAKEMURA SHUHEI
IPC: B65H1/12
Filed: 1986-09-29
Abstract: PURPOSE:To make the loading and removing of a cassette so easy, by installing a device which converts the normally constant displacement of a displacement member by the paper feed cassette into force of a presser spring of a cassette bottom plate presser arm according to a quantity of sheets inside the cassette. CONSTITUTION:At the time of a cassette 1 being loaded, a slant face 4 of a cam 2 presses a cam follower 5 down by the forward movement, rotating a lever 7, and a gear 8 is rotated thereby, and a gear 11 is reversed, whereby a presser arm 16 is rotated upward via a presser spring 13. When the cassette further goes forward, a projecting part 3 of the cam 2 enters a groove part of a cassette receiver 21 and it is positioned. At this time, the cam follower 5 has already entered beneath the cam 2, pressing this cam 2 to the upper direction. Pressing force of stacked sheets to a paper feed roller is designed as related to displacement of the presser spring 13 and a quantity of sheets so that it is kept constant. Therefore, at the time of loading, the cassette can be loaded with only such force that is equivalent to force of the presser spring 13 corresponding to the sheet quantity, so that loading and removing of the cassette is performable with small force.

Title: Fuel cell
Inventor: OOGA SHIYUNSUKE
IPC: H01M8/06
Filed: 1983-12-08
Abstract: PURPOSE:To obtain a fuel cell whose deterioration rate of electrolyte is small and electrolyte replacement is rarely necessary even if air is used as oxidizing gas by preventing penetration of carbon dioxide to an electrolyte line. CONSTITUTION:A fuel gas is extracted from a fuel gas circulation line 10 with an extracting pipe 14 and introduced to an electrolyte tank 32 as shown by arrow F. The extracted fuel gas covers the surface 32a of the electrolyte as cover gas and exhusted outside from a small hole 32d as purge gas, or burned if necessary. By this process, contact of electrolyte with carbon dioxide is prevented, and deterioration of electrolyte caused by carbonate produced by contact of carbon dioxide and alkaline electrolyte is decreased. Since the liquid surface of the electrolyte tank is kept under atmosphere and does not vary virtually, electrolyte volume resulting from liquid level of electrolyte is accurately controlled.

Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To heighten holding capacity by composing a sub-chuck device of a band plate like sub-chuck member for gripping a casing tube, and a sub-chuck cylinder for enlarging/contracting the sub-chuck member. SOLUTION: While rotating a casing tube 12 gripped by a chuck member 9 of a main chuck device 7, an elevating frame 3 is lowered and pushed into the ground by an elevating cylinder 4 to excavate sediment in the tube 12. Reinforcements are arranged in the tube 12, and concrete is placed. A sub-chuck cylinder 16 is then contracted to contract the diameter of a sub-chuck member 15 to grip the tube 12, and then the tube 12 is pulled out by one stroke part of the elevating cylinder 4. The grip of the tube 12 is released, and the cylinder 4 is shortened to lower the frame 3. The tube 12 is gripped by the chuck member 9. The frame 3 is then raised, and after placing concrete in the tube 12, the tube 12 is pulled out. The same process is further repeated to construct piles.

Title: Motor structure
Inventor: MATSUURA HIDEMI
IPC: H02K1/26
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To suppress increase of iron loss due to field variation acting on a pole end by forming the stator tooth surface of a motor irregularly thereby decreasing the gap width. SOLUTION: The stator 10 of a motor has irregular tooth surface 11 having radial length varying stepwise in the circumferential direction. The gap between the stator 10 and a rotor 1 is minimized. Since the irregular tooth surface 11 is provided, eddy current loss due to leakage flux in the gap can be reduced on the stator tooth surface and motor efficiency can be enhanced because exciting current can be reduced by decreasing the equivalent gap length.

Title: Camera
Inventor: SASAKURA TAKAO
IPC: G02B7/28
Filed: 1991-09-11
Abstract: PURPOSE:To prevent the focusing rate of automatic focusing (AF) from lowering by extending the focusing width of the AF and stopping down a diaphragm for several steps when a still video back (SV back) is attached. CONSTITUTION:As to a camera Y, the SV back 7 is attached to the back cover part of the camera which photographs a video by using a silver salt film. An automatic focusing control means A extends the focusing width of the AF when the SV back is attached to the camera Y. At such a time, an automatic exposing control means B executes automatic exposing based on a reference value which is set to a direction where the diaphragm is more stopped down that at the diaphragm value in ordinary automatic exposing. Namely, when the state of the back cover of the camera Y is detected to find that the back cover is the SV back 7, the numerical value of the focusing width used for deciding focusing on an AF action is set larger than that in an ordinary silver salt camera. Since the video is easily blurred when the focusing width is extended, the diaphragm is more stopped down by a couple of steps than at the diaphragm value at actual photographing in order to make the depth of field deep.

Abstract: PURPOSE:to execute an exponent-vector conversion by a small circuit quantity, by constituting an exponent-vector converting circuit in a digital processing circuit, of a gate circuit and a multiplying circuit. CONSTITUTION:When a binary expression of a code length (n) has been sent in order of N0 N7, alphaN<0> alphaN<7>.<128> are outputted to a bus line Y, and sent to a multiplying circuit 2. From an output Z of the multiplying circuit 2, outputs multiplied by alphaN<0>-alphaN<7>.<128> are outputted successively. Its output is fetched in a register 3, and output to the other input terminal X of the multiplying circuit 2. Also, to X, the contents of the register are set in advance so that '1' is outputted, when Y has outputted alphaN<0> has been outputted first. When alphaN<7>.<128> has been outputted, alpha<n> is generated. A clock pulse HCK is outputted from a clock oscillator, while N0-N7 are being outputted. In this way, a conversion from an exponent expression (n) to a vector expression alpha<n> can be executed by a gate circuit and a multiplying circuit which have been simplified.
