Title: Photodetector
Inventor: NAGAI SEIICHI
IPC: G11B7/13
Filed: 1985-09-17
Abstract: PURPOSE:To obtain a photodetector which acts normal tracking operation by slanting a resonator end surface nearby a light emission point so that a part which has an angle smaller than 90 deg. to return light is obtained. CONSTITUTION:When a three-beam type optical disk is tracked by using a semiconductor laser diode chip 13, return light beams 11a, 11b, and 11c which are reflected by the disk return to the light emission point 8, a point 9 on the slanting surface 16 of the semiconductor diode chip 13, and a point 10 on the surface of the semiconductor laser diode chip 13 respectively. The return light beams 11a and 11c are reflected as usual, but the return point 9 of the return beam 11b slants at some angle, so reflected light 12b from the photodetection point 9 is reflected in a direction different from the return light 11b. Therefore, the return ligth from the photodetection point 9 to a subordinate beam is nearly eliminated as well as return light to the subordinate beam from above the surface of the semiconductor laser diode chip 13, so there is no influence upon the balance of the quantity of light between the two subordinate beams.

IPC: F16L47/02
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To improve workability by rotating an adapter against a saddle under a condition that a cap nut which is screwed around a male screw and has a pushing/ pressing part by which a flange is pushed and pressed to the end surface of a short pipe part, is loosened, and adjusting the direction of a snap tap connected to the adapter. SOLUTION: On end part of an adapter 20 is fitted to the inner circumferential surface of a short pipe part 30. A cap nut 22 is screwed around the male screw 32 of the short pipe part 30, and also the male screw 48 of a snap tap 18 is screwed in the female screw 58 of the adapter 20. When a water supply pipe 14 is connected to a main pipe 12 by using a snap tap 10 with a saddle, the faying surface of the saddle 16 is tightly stuck to the peripheral surface of the main pipe 12. Subsequently, a resin is heated and melted by using a current-carrying device, and the saddle 16 and the main pipe 12 are fused. When a fused part is cured, the adapter 20 and the snap tap 18 are rotated under a condition that the cap nut 22 is loosened, so that the direction of the snap tap 18 can be adjusted.  Then, the cap nut 22 is fastened and a flange 60 is pushed and pressed to the upper end surface of the short pipe part 30 by a pushing/pressing part 22a, thereby the adapter 20 and the snap tap 18 can be fixed to the saddle 16.

Title: Noise suppressing circuit
Inventor: MAEZATO SHINICHI
IPC: H04N5/21
Filed: 1989-08-10
Abstract: PURPOSE:To enable noise suppression processing wherein the contour of an image is held in real time with simple circuit constitution by substituting an optional picture element signal with a signal indicating the mean value of the video level of the optional picture element signal and the video levels of adjacent picture element signals around the picture element when the level of a contour signal is smaller than a specific value. CONSTITUTION:This circuit is equipped with a two-dimensional filter M1 which detects the contour of the image according to the output signals of delay lines D1-D9, a two-dimensional filter M2 which finds the mean value of output signals a1-a9, a comparator M3 which compares the contour signal (b) with a coefficient (k) ' and a switch circuit S1. Then the correlativity between the optional picture element and adjacent picture elements is decided with the level of the contour signal (b) and when the level is small, it is decided that there is the correlativity and the mean value of the picture element and adjacent picture elements is found; when the level large, on the other hand, it is decided that there is not the correlativity and the mean value is not found. Consequently, noises of the image can be suppressed without deteriorating the resolution of the contour part of the image and the processing is performed in real time with the simple circuit constitution.

Title: Sheet feeding device
Inventor: FUKAZAWA AKIRA
IPC: B65H3/06
Filed: 1990-08-03
Abstract: PURPOSE:To stop a separating roller at the time of excessive load and prevent the damage to a driving system by driving the separating roller reversely rotating to the feed direction through a friction member and an one-way clutch. CONSTITUTION:When a sheet to be fed between a feed roller 1 and a separating roller 2 is one, the frictional force between the feed roller 1 and the sheet is larger than the frictional force with the separating roller 2, so that the sheet is fed in accordance with the rotation of the feed roller 1. When two or more sheets are fed, the sheets are returned by the reversely rotating separating roller 2 except the sheet in contact with the feed roller 1 to present the double feed. A gear 3 for driving the separating roller 2 rotates the separating roller 2 by pressing a frictional member 4 into contact with a disk 5 fixed to the separating roller 2 by a spring 6 and prevents its normal directional rotation by an one-way clutch 9. Thus, when an excessive load is added to the separating roller 2, a slippage is caused between the disk 5 and the frictional member 4 to stop the rotation of the separating roller 2, and a damage to a driving system is prevented.

Title: Production of emulsion
Inventor: FUNADA KOICHI
IPC: C08J3/07
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To efficiently produce an O/W emulsion having a specified average particle size or smaller by a simple process with a simple apparatus by constituting a circulation system of an emulsifying vessel and a high-pressure homogenizer, and by charging an oil phase and a water phase at a specified wt. ratio into the emulsifying vessel and then mixing them under circulation while the oil phase is being added to the emulsifying vessel. SOLUTION: An oil phase and a water phase in a wt. ratio of oil phase/water phase of (0/100)-(40/60) are charged into an emulsifying vessel to produce an O/W emulsion having an average particle size of 1 μm or smaller. The oil phase and the water phase are separately charged into the emulsifying vessel without using a pre- emulsifying apparatus. Premixing after the oil phase and the water phase are charged is preferable, since the emulsifying time can be decreased in the mixing under circulation. It is sufficient if the premixing is done under unvigorous stirring by using an anchor blade or the like. Preferably, the addition of the oil phase is completed at an O/W ratio of at most (60/40).  The addition in the case when the mixing under circulation is done while the oil phase is being added may be carried out by any method other than the addition at one time, though the rate of addition is preferably not higher than the rate of liquid transportation by the high-pressure homogenizer.

The circuit 5 gives an alarm sound from a speaker 9 when the value of the current for driving the motor 2 detected by the means 6 is greater than a value set in advance by a load setting handle 10. In this way, an alarm giving means 11 is constituted from the control circuit 5 and the speaker 9.

Thus, a semiconductor layer of long life can be manufactured.
