Title: Servo device of magnetic recording and reproducing device
Inventor: NISHIJIMA HIDEO
IPC: G11B15/467
Filed: 1983-04-15
Abstract: PURPOSE:To reduce the deterioration of S/N ratio, etc. in picture quality at the place near a joint area by deciding the phase jump of a capstan servo system of a consecutive recording mode from the resolution of the clock frequency which produces a reference signal. CONSTITUTION:When a pause switch 19 is operated, a record state (''L'' period) is set with a delay equivalent to a period of time required for matching of phase between the synchronizing signal on a magnetic tape 1 and the synchronizing signal to be newly recorded as shown in a waveform 21 given from a system controller 20. Then a signal generator 33 delivers at least >=1 shot pulse outputs 34 which are synchronous with the output 28 of a frequency divider 18. Thus a frequency divider 32 is preset. At the same time, a switch 12 is inverted. Then the input to be supplied to a phase comparator 15 is changed to the output 28 of the divider 18 from a reproduction synchronizing signal 27. The phase jump which is generated at this time point is set at maximum (2pi/M) radian as shown by a waveform 35 in the figure, where M defines the dividing ratio of the divider 32.

IPC: A61B5/023
Filed: 1988-03-22
Abstract: PURPOSE:To completely return mercury into a mercury sump from a mercury passage in association with the closing of a lid by connecting an air pump to the top end of the mercury passage through a tube and by operating the air pump in association with the closing of the lid. CONSTITUTION:When a lid 13 is opened, since a lever is upright, a valve 26 is opened so as to communicate a mercury passage 1 with a mercury sump 2. At this time, in an air pump 19, a rod 23 fully extends while a piston in a cylinder 20 is positioned in the lowermost part so as to open a hole formed in a side wall, and accordingly, the inside of the cylinder is communicated with the atmospheric air so as to enable measurement of a blood pressure. After use, when the lid 13 is made to be side-long, the lid 13 is moved about a shaft 30 as a center, and at this time, a roller 29 pushes up the rod 23. Then, a piston 22 blocks up a hole 22 while performing a pump action so as to drive air previously trapped in the cylinder into the mercury passage 1 through a tube 28. As a result, mercury 12 is returned into the mercury sump 2 from the mercury passage by way of a communication pipe 3, and the lever 25 is folded so as to close the valve 26.

Title: Fitting type connecting mechanism
Inventor: TANAKA TETSUO
IPC: H04B1/38
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To prevent a shaft and flange part from slipping off from a hole even if, for example, a hand is detached from a portable telephone at a time point when the shaft and the flange part is moved to a small hole part by arranging a narrow part on a boundary part between a large hole part and a small hole part in a hole. SOLUTION: In the case where a shaft 22 is moved from a large hole part 33a of a hole 33 to a small hole part 33b, the shaft 22 abuts on a shaft 37 when the shaft 22 reaches a boundary part between the large hole part 33a and the small hole part 33b of the hole 33. When force is applied on the shaft 22, the shaft 22 rides over a narrow part generated by the projection part 37, and is moved to the small hole part 33b. When the shaft 22 is inserted into the small hole part 33b, the projection part 37 is acted as a stopper in the case where the shaft 22 is moved to the large hole part 33a.  If a hand is detached from a portable telephone at the time point when the shaft 22 is moved to the small hole 33b and the portable telephone falls down by a self weight, the shaft 22 and the projection part 37 abut on each other, and thereby, the shaft 22 is prevented from moving to the large hole part 33a. Since the shaft 22 is held in the small hole part 33b, the shaft 22 and the flange part 23 are prevented from slipping off from the hole 33.

Title: Method of preventing sticking of oil carbide to pipe worked by cold pilger mill
Inventor: SHIKINE YOSHIYUKI
IPC: B21B21/00
Filed: 1985-03-28
Abstract: PURPOSE:To remove easily the oil sticking to a worked pipe by forming the passage in a crank chamber into a channel or pipe and supplying the same oil as the oil used in drawing thereto during the time when the pipe passes through said passage thereby cooling the pipe. CONSTITUTION:The product pipe 6 heated up by drawing is cooled as the pipe enters the passage 20 if the pipe is drawn while the same oil as the roll oil used in the drawing part is thoroughly supplied to the passage from an oil nozzle 27. More specifically, the oil entering the passage 20 through an oil accepting port 22 contacts with the outside surface of the product pipe 6 while flowing toward the outlet side and cools the same. The pipe during working progresses intermittently and rotates at a prescribed angle at every one progress and therefore the entire circumference is uniformly cooled by contacting with the oil even if the pipe 6 is not thoroughly submerged in the oil in the passage 20.

Title: Semiconductor ic device and manufacture thereof
Inventor: TANIGUCHI TAKASHI
IPC: H01L27/04
Filed: 1984-04-04
Abstract: PURPOSE:To contrive the reduction in manufacturing cost by a method wherein the mutual wiring of logical circuits of the (i-1)-th layer and the i-th layer is made only as the input wiring from the i-th layer to the (i-1)-th layer, and the (i-1)-th layer is inspected by impressing a potential as required. CONSTITUTION:Logical circuits 1, 2, and 3 are laminated in the order of (i-1), (i), and (i+1). Nodes N1-N3 of the input signal from the layer 3 to the layer 2 are connected to the same pad 6. In this case, no input of all the logical circuits is open. When signals of high potential are impressed on the inspection pad 6 by connecting power sources and grounds for every layer, a gate NAD1 becomes equivalent to an inverter, and a three-input gate NAD2 equivalent to a two-input gate; besides, a gate NOR1 to which the output of IV1 has been connected becomes equivalent to the inverter. When a signal is given to each input pad 4, the output corresponding to the logic up to the i-layer 2 appears in the pad by its combination. If it is different from an expected logical value, it is judged as defective below the i-layer 2, and the manufacture of after (i+1)-layer is stopped. This construction enables the reduction in cost by shortening the time for manufacture and inspection.
