Title: Optical pickup device
Inventor: HONDA SHUICHI
IPC: G11B7/135
Filed: 1990-02-05
Abstract: PURPOSE:To accurately execute tracking detection by setting up a distance from the incident light deflecting point of a deflecting member up to the center of a moving lens about twice as long as the focal distance of an objective lens to an optical disk. CONSTITUTION:When the distance from the incident light axis deflecting point P of the deflecting prism 20 up to the center of the objective lens 19 is l and the focal distance of the objective lens 19 to the optical disk 1 is (f), l=2f is set up. When a carriage 18 is rotated around the X axis rectangular to its seaking direction S only by angle theta, an offset value DELTAx between the incident light axis 23 to the prism 20 and reflected light axis 24 from the prism 20 is found out by the shown equation I. When l=2f is substituted for the equation I, DELTAx=0 is formed, so that even when the carriage 18 is inclined by the angle theta, the incident light axis 23 coincides with the reflected light axis 24 and accurate tracking detection can be attained.

Title: Multilayer printed wiring board
Inventor: KUWABARA NORIO
IPC: H05K3/46
Filed: 1990-02-07
Abstract: PURPOSE:To reduce a crosstalk caused by crossed interconnections by a method wherein an insulating layer is formed to be thicker than other signal-layer pairs and a signal-layer pair in which a signal line having a comparatively long section length has been wired is installed at a signal-line layer. CONSTITUTION:The distance (a) between a signal layer 2 and a signal layer 3 in a signal-layer pair 8 is set to be longer than the distance (b) between a signal layer 4 and a signal layer 5 in a signal-layer pair 9. A signal line having a comparatively long section length is wired in a signal-line layer of the signal- layer pair 8. By this constitution, the signal line which has been wired in the signal-layer pair 8 is hardly influenced by an interlayer crosstalk as compared with a signal line which has been wired in the signal-layer pair 9. When a wiring operation is executed to the signal-layer pair 8 hardly influenced by a crosstalk by crossed interconnections preferentially from a long interconnection, it is possible to design an interconnection which is hardly influenced by the crosstalk by the crossed interconnections as a whole substrate.

Title: Mounted structure of low tank
Inventor: ISOU KAZUYOSHI
IPC: E03D1/26
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To enhance workability by passing a bolt that is suspendedly installed on the bottom surface of a low tank through a mounting hole provided in a toilet bowl main body and the diameter of which decreases downward from the top. SOLUTION: To place a low tank 2 upright on the upper surface of the rear of a toilet bowl main body 1, tightening bolts 5 suspendedly installed on the bottom surface of the tank 2 are passed through mounting holes 6 formed vertically through the main body 1, and nuts are tightened around the bolts 5 from below the main body 1 for fixing. In this case, each hole 6 is formed into a taper shape whose diameter is decreased downward from the upper surface. Thus when the tank 2 is lowered toward the main body 1, the bolts 5 are so easily inserted into the holes 6 that a conventional strained job of lowering the tank 2 while looking at the bottom of the tank 2 in order to align the bolts 5 correctly with the holes 6 is not needed and an operation can be done while concentrating solely on the effort to connect a float valve to a wash water distributor.  Therefore, the tightening bolts can easily be inserted into the mounting holes, and the low tank can be mounted on the toilet bowl main body very easily.

Title: Paper drawing out device in paper counter
Inventor: IMAI SHIGETOSHI
IPC: B65H1/06
Filed: 1983-02-17
Abstract: PURPOSE:To improve the paper separating function as well as the accuracy in counting by taking in some sheets of paper by means of a draw-out roller and a take-in roller which have frictional and non-frictional surfaces respectively, sending them into a separating roller, and stopping the rotation of said separating roller as the paper enters said separating roller. CONSTITUTION:As a draw-out roller 3 rotates in the (b) direction, a take-in roller 7 which is frictionally brought in contact with the draw-out roller 3 rotates in the (c) direction. And, a separating roller 4 which is interlocked by means of gears 8, 9, rotates in the (d) direction. Thereby, some sheets of paper which are kicked out, are sent through each roller 2, 3, 7, and their ends are brought in contact with the separating roller 4. Thus, when some sheets of paper 1 enter the separating roller 4, a one-way clutch, not indicated in figure, operates and the rotation of both the separating roller 4 and the take-in roller 7, which is interlocked with the roller 4 through gears 8, 9, are stopped, separating the sheets of paper which are sent in piles. Thus, the separation of sheets of paper can be securely carried out improving the reliability.

Abstract: PURPOSE:To smooth a work to insert a hinge pin through a hinge member and mount the pin by a method wherein the hinge pin inserted in a door hinge member in a way to protrude a door support part from the car body side is brought into contact with a car body hinge member, and after dislocation of the pin, it is protruded by a given distance. CONSTITUTION:A door support part 14 is protruded toward the car body B side in a state in which a hinge pin 1 is inserted in a hinge member H2 of a door D by means of a mounting means F. The hinge pin 1 is brought into contact with a hinge member H1 of the car body B as displacement in a position of the two hinge members H1 and H2 is absorbed by means of a resilient member (a). Thereafter, through dislocation of the hinge pin 1 from the hinge member H2, the door support part 14 is protruded toward the car body B side by a given distance. Displacement in a position of the pin insertion holes of the two hinge members H1 and H2 is reduced as much as possible, and with this state, a mounting means F is actuated again to insert the hinge pins 1 in the two hinge members H1 and H2. This constitution smooths a work to insert the hinge pin through the hinge member and mount the pin and enables execution of an excellent work to mount the door.
