Patent JP-H0249294-A (JP)
Title: Semiconductor memory cell
Inventor: IRIKITA SHIGEYOSHI
IPC: H01L27/102
Filed: 1988-08-10
Abstract: PURPOSE:To form a high-speed semiconductor memory having large capacity by composing load resistance of active resistance by a field effect transistor, heightening the ratio of a reading current to a holding current, and reducing a chip area. CONSTITUTION:Under a held state, diodes D1 and D2 and transistors TRsQ3 and Q4 are under a cutoff state, a holding current IH is applied through a TRQ5, and although the current IH lowers the collector potential of a TRQ2, the TRQ3 is not made into a conductive state. Further, voltage VBE between the base and the emitter of the TRQ4 is approximately OV, under a non-conductive state, and stable in the held state. On the other hand, under a selected state, the potential of a word line WT rises to high potential VWTH, and a reading current IR is applied through the TRQ5 to the TRQ2. In such a manner, the load resistance of TRsQ1 and Q2 is composed of the field effect active resistance with TRsQ5 and Q6, and while the load resistance can be high under the held state, the load resistance can be low under a read state. As the result, the ratio of the reading current IR to the holding current IH becomes larger, and the chip area can be reduced by providing gate electrodes G1 and G2 for the upper parts of TRs3 and 4 and forming the TRsQ5 and Q6.

Title: Endoscope
Inventor: MORI TETSUAKI
IPC: A61B1/00
Filed: 1989-08-01
Abstract: PURPOSE:To enable a tip side of endoscope to be made slim by forming an annular concave part on outer peripheral face of a bending piece at the endmost tip of the endoscope, fitting and fixing a cover member of the bending piece to the concave part. CONSTITUTION:A tip construction 21 is cylindrical in shape and formed with a tip hardware 25, which is made small in diameter by a step at its rear end side. The endmost bending piece 26 is fit and fixed to the outer face of the small diameter part of the tip hardware 25. This bending piece 26 is cut out annularly at e.g. its outer periphery of front end side to form an annular concave part 63 with a diameter made smaller by the depth of cut-out. As a tip of a blade 61, which covers at least a bending part 22, is received in this annular convex part 63 and fixed by solder 64, the tip construction 21 is prevented from becoming large in diameter. Furthermore, holes 65 are formed by turning down slit parts at the top, bottom, right and left of the concave part 63, and every wire 57i is inserted through the holes and fixed to the concave part 63 with silver solder 66.

Title: Brake hydraulic control device
Inventor: TANGE KENJI
IPC: B60T8/48
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent the air from being trapped into a brake liquid by setting an intake passage and a discharge passage coaxial to the straight axis of a conduit. SOLUTION: An intake valve 22 and a discharge valve 23 are caulkedly fixed within a pipe line 3. More specifically, the pipe line 3 is separated to two lines by a housing space 5, the discharge valve 23 is fixed to the master cylinder side line 3a, and the intake valve 22 to an ABS control reservoir 1 side line 3b. Since the discharge valve 23 and the intake valve 22 are arranged within the straight pipe line, considering the flowing passage of a brake liquid by a plunger pump 2, the passage for sucking the brake liquid from the ABS control reservoir 1 and the passage for discharging the sucked brake liquid are concentrically linearly arranged. When the passage for sucking the brake liquid and the passage for discharging the brake liquid are laid in concentrically linear state, air, even if included in the brake liquid, is never trapped.

Title: Valve timing control device of internal-combustion engine
Inventor: NAKAMURA NORIHIKO
IPC: F01L1/34
Filed: 1982-11-19
Abstract: PURPOSE:To prevent the ignition time from being staggered by switching the ignition time when the valve timing is switched. CONSTITUTION:A distributor 36 has two contacts 130A, 130B operating at two different angle positions. When the valve timing is set to the first value, an output High is outputted from an input/output port 83. Accordingly, a transistor 132B is made off and 132A is made on, thereby the ignition time is determined by the contact 130A. When the valve timing is set to the second value, an output Low is outputted from the input/output port 38. Therefore, the transistor 132A is made off and the transistor 132B is made on, thus the ignition time is determined by the contact 130B. Accordingly, the ignition time is not staggered even if the valve timing is changed.
