Inventor: TANAKA SEIGO
IPC: F02D45/00
Filed: 1994-11-25
Abstract: PURPOSE: To reduce the harmful substance in exhaust gas which is generated at the time of start, and purify exhaust gas by changing a first valve means into first condition and closing a second valve means when rotary speed is a prescribed value and less, and changing the first valve means into second condition when rotary speed is a prescribed value or more. CONSTITUTION: When speed of an internal combustion engine 12 which is found out from detection result of a crank angle detector 41 is a prescribed value or higher, a flow-in switching valve 16 is changed in condition in which exhaust gas is led into an exhaust pipe 13a and also a pipe passage 34 is shut out showing a two point broken line 16a, exhaust gas which is discharged when the internal combustion engine 12 is started is reserved in a reserving means 15, and after that, exhaust gas which is discharged from the internal combustion engine 12 is led into a purifying means 14.  When the temperature of cooling water which passes a cooling means 22 is detected by a cooling water temperature detector 43 and the temperature is high, a flow-out valve 17 is opened, an outlet 37 is opened, and exhaust gas which is reserved in a reserving means 15 is led to a purifying means 14 through the pipe passage 35 and the exhaust pipe 13a.

Title: Semiconductor storage device
Inventor: HORIUCHI KATSUTADA
IPC: H01L27/102
Filed: 1987-11-20
Abstract: PURPOSE:To acquire a hyperfine and high integrative dRAM cell without developing troubles such as intercell interference, word wiring interference and alpha-ray soft errors, and without redistributing a p<+> impurity by completely partitioning a capacity element as well as a switching transistor from a semiconductor substrate. CONSTITUTION:A polycrystal Si film 12 operates as a plate electrode and constitutes a charge accumulating capacity element with an SiO2 film 11 and an N+ buried diffusion layer 2. Writing and reading of data (charge) to the capacity element depends on a bi-polar transistor which is provided with bilateral characteristics. A base leading electrode 14 which is used as a word wire is connected at a side wall of a base region 17. The electrode 14 is also composed self-matchingly with a monocrystal region. Only one contact hole is provided to connect bit line 21 and an emitter region 19, and accumulated capacity can be easily increased by increasing the area of an N+ buried layer side wall section. Each unit cell is constructed to be completely isolated from each other and from an Si substrate 1 through a plate electrode consisting of a polycrystal Si film 12. In this way, intercell interference and soft error defectives due to alpha-ray irradiation are essentially solved.

Abstract: PURPOSE:To increase high rate charge-discharge efficiency and to decrease self-discharge rate by specifying pore volume to 0.7-1.5cc/g, and the volume of pore having a pore diameter of 30Angstrom  or more or 17Angstrom  or less, and also specifying the contents of ash, sodium, and potassium. CONSTITUTION:Activated carbon fibers are specified so that the pore volume is 0.7-1.5cc/g, and the volume of pores having a pore diameter of 30Angstrom  or more or 17Angstrom  or less is 30% or less, and also ash is 0.2% or less, and the contents of sodium and potassium are 20ppm or less and 10ppm or less respectively. IN order that the volume of pores having a pore diameter of 30Angstrom  or more does not exceed 20% based on the total pore volume, activation time and activation temperature are controlled. Activated carbon fibers are washed with acid to remove ash so that the content of ash is 0.2% or less, sodium content is 20ppm or less and potassium content is 10ppm or less, then heated in an inactive atmosphere at 700-1,050 deg.C. By this heat treatment, pores having a pore diameter of 17Angstrom  or less are decreased.

Title: Spherical joint for space truss and member-jointed space truss structure using the joint
Inventor: IMAI KATSUHIKO
IPC: E04B1/342
Filed: 1994-10-31
Abstract: PURPOSE: To reduce an axial force to be transmitted to a connection spherical joint between a chord member and a brace or the like, and simplify the structure of the spherical joint to facilitate the joint work on the site. CONSTITUTION: In a spherical joint 2, a cylinder-shaped hole 2a is formed which allows a chord member 1 to pass through the center of a solid sphere, while a screw hole 2c is installed to a solid part 2b around the cylinder-shaped hole 2a so as to thread a connection bolt 3A on one hand. The spherical joint 2 is preliminarily welded with the chord member 1. A brace 4 is fastened with a bolt by using a joining device 3 on a truss construction site. The spherical joint 2 allows the chord member 1 to be passed, which prevents an axial force acting on the chord member from being directly exerted on the spherical joint 2. Therefore, in the manufacture of the joint 2, it is sufficient if the joint 2 can sustain a small axial force transmitted from the brace 4.  By such a construction simplification of the structure of the sphere-shaped joint 2 and reduction in the weight can be attained and onsite welding work may be eliminated and it facilitates assembling work of truss structure by a small bolt-connecting work.

Title: Bottle pocket fixture
Inventor: NAMIHANA ISAO
IPC: F25D23/04
Filed: 1990-10-30
Abstract: PURPOSE:To enable more positive mounting by simple constitution, and to improve appearance by making the width of the through-hole of an internal sidewall, into which the head section of a fixture is inserted, narrower than the maximum width of the head section. CONSTITUTION:A fixture 3 has only a bottle pocket 2 and a head section 3b for fitting. A cross section is formed in a wedge shape and the head section 3b has width W in the same manner as conventional devices, but a second through-hole 11b formed at the projecting-section nose section of an internal sidewall 11 is constituted so that width S<W. Consequently, the head section 3b of the fixture 3 is inserted while pushing and expanding the second through-hole 11b having narrow width, is projected and a root section having narrow width is held by the internal sidewall 11 having elastic force, thus preventing the slip-off of the head section 3b by a wedge effect. A notch section 11d having wide width is formed connected to the upper and lower sections of the second through-hole 11b, thus easily inserting the fixture 3. The head section 3b of the fixture 3 projected from the internal sidewall 11 is pushed into and fitted into the fitting section 2a having a C-shaped cross section of the pocket 2, but the head section 3b is not pulled into a door 1 on the fitting operation, thus improving the efficiency of assembly operation.

Title: Controlling apparatus for direction of laser beam
Inventor: KAMEYAMA TAKAHARU
IPC: H04B10/11
Filed: 1989-11-09
Abstract: PURPOSE:To control the direction of laser beams with high accuracy by automatically correcting the optical axis of the laser beams and automatically correcting the positional displacement of a target. CONSTITUTION:A gimbal part 11 adds scanning motion to a sending telescope 2 and a receiving telescope 1. The telescope 2 sends laser beams of a laser apparatus 13 to the scanning space, and the telescope 1 guides the receiving light to a dichroism beam splitter 3. The receiving light in the visible range is supplied to a pickup camera 5 which in turn searches for a flying object in the scanning space. After the flying object is found, the camera 5 continues to supply the positional information to a target tracing circuit 12. The circuit 12 generates and supplies a target tracing signal to the gimbal part 11. Moreover, the components of the receiving light outside the visible range are guided to a 4-quadrant photodetector 10. The detector 10 having a narrow visual field supplies the positional information of the flying object in the quadrant area to an angular error operating circuit 21. Then, the circuit 21 operates the angular error of the transmitted laser beams to the flying object. Since a driving circuit 22 and an automatic mirror gimbal 7 drives a reflecting mirror 6 so that the angular error becomes zero, the direction of the laser beams can be corrected with good accuracy.
