Title: Ignition timing control device in internal combustion engine
Inventor: YAGI SHIZUO
IPC: F02P5/15
Filed: 1985-08-09
Abstract: PURPOSE:To make it possible to effectively act engine brake, with the use of an instruction pressure signal responsive type ignition control device, by retarding the ignition angle or cutting off the ignition when a light load is detected during running at a high speed. CONSTITUTION:An ignition angle setting circuit 8 receives a read-out instruction signal from a decoder 11 and takes in the latch content of a latch circuit 10 as an instruction pressure peak position data. Then, it is determined whether the instruction pressure peak position data is greater than a desired instruction pressure peak position or not, and if it is greater, a spark advance is made by a predetermined angle while if it is less, a spark retardation is made by a predetermined angle to set an ignition angle. At this time when it is determined that the rotational speed of the engine is higher than a predetermined value and the opening degree of a throttle valve is less than a predetermined value, in accordance with a signal from an engine parameter sensor 12, it is judged that an engine brake condition is effected, and the desired instruction pressure peak position is shifted far from TDC in comparison with that in the normal operating condition.

Title: Preparation of vinyl chloride resin
Inventor: INAGE KOJI
IPC: C08F2/24
Filed: 1990-07-04
Abstract: PURPOSE:To eliminate the variation in polymn. time and prepare a vinyl chloride resin in a short time by charging a polymn. kettle with water and additives, feeding a surfactant beneath the water level in the kettle, subjecting the contents in the kettle to a vacuum deaeration treatment, feeding vinyl chloride, and starting the polymn. CONSTITUTION:After a polymn. kettle is charged with water and other additives, a surfactant (e.g. sodium dodecylbenzenesulfonate) is fed beneath the water level in the reactor; the contents of the kettle is subjected to a vacuum deaeration treatment to remove oxygen in the kettle and oxygen dissolved in the water; and vinyl chloride or a mixture thereof with a copolymerizable vinyl monomer (e.g. acrylic acid) is fed thereto to start the polymn. As the surfactant is fed beneath the water level, foaming during the vacuum deaeration treatment is avoided, and thus the polymn. time can be reduced.

Filed: 1981-10-31
Abstract: PURPOSE:To perform the accurate positioning of a head, by shifting the head until the coincidence is obtained between the scale number detected by a position detector and the arithmetic result of the scale corresponding to an access track and the compensated scale number in an access mode. CONSTITUTION:An optical disk 11 is turning at a constant speed. Thus the signals are delivered from a pulse generating circuit 26 with the detecting signals of different phases supplied from a detector 18 every time the scale has the correspondence successively at and after the scale at the initial position of an optical scale 17. Then an optical head 13 counts up a counter 27. The head 13 irradiates the reproduced beam on the disk 11 and converts the reflected beam into electric signals to deliver them to a CPU. The CPU detects the most inner circumference track with the electric signals supplied from the head 13 and delivers the detecting signals to a compensated scale register 20.

IPC: G01N27/26
Filed: 1981-10-30
Abstract: PURPOSE:To determine a potential gradient of a terminal ion exactly by recognizing the largest of potential gradients as such among ion component zones existing until the recognition time passes. CONSTITUTION:A potential gradient detector of an equispeed electrophoresis analyzer 2 outputs a signal beta to a data processor 3 which detects a potential gradient and a zone length of individual ion component zones based on the signal beta, while the signal beta is compared with a preset threshold V. The counting of time begins when the signal beta exceeds the value V to select ion component zones Ii contained in signals inputted until the recognition time predetermined is reached from the start of the counting. Then, potential gradient values Pi of the ion component zones are compared to select the largest potential gradient value. Thereafter, the device 3 recognizes the largest potential gradient value as potential gradient of the terminal ion to determine a PU value of the ion components which is outputted to a printer plotter 4.

Inventor: NAKAKOJI YOSHIHIKO
IPC: F04B7/00
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To avoid crossing in an advance-retreat member of a pressure introducing passage to respective cylinder chambers by arranging a pair of high pressure grooves respectively adjacent to the advance side and the retreat side of a low pressure groove in a spool holding hole, and respectively introducing fluid pressure to a first cylinder chamber and a second cylinder chamber from the nearest high pressure groove. SOLUTION: When servo spool 15 advances, a port 21 communicates with a high pressure groove 182 , and fluid pressure enters a cylinder chamber 9. On the other hand, a port 20 communicates with a low pressure groove 16, and a cylinder chamber 13 is opened to a low pressure area. Therefore, an advance-retreat member 1 is energized in the advance direction, and follows the servo spool 15. When the servo spool 15 retreats, the port 20 communicates with a high pressure groove 181 , and the fluid pressure enters the cylinder chamber 13. On the other hand, the port 21 communicates with the low pressure groove 16, and the cylinder chamber 9 is opened to the low pressure area.  In this way, the fluid pressure from a high pressure port 19 is branched off into high pressure introducing grooves 191 and 192 , and is introduced to the high pressure grooves 181 and 182 , and the high pressure grooves 181 and 182 are individually communicated, and are not crossed with each other.

IPC: B42D15/10
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To provide an optical card consisting of an optical recording member embedded in the recessed part of a card base material. SOLUTION: This optical card includes an optically recording member 5 with an optically recording layer 4 laminated on a transparent protecting layer 3 by covering a track pattern 2 formed on the lower surface of the transparent protecting layer 3, and a card base material 6, in the recessed part 7 of which the optically recording member 5 is embedded through an adhesive layer 8. The tensile strength of the transparent protecting layer 3 should be the same as or at least, approximate to that of the card base material 6. Alternatively, the difference between the tensile strengths of both transparent protecting layer 3 and card base material 6 is set to the range of 100kgf/cm<2> or less. Otherwise, the difference between the rupture elongation percentages of both is set to the range of 50% or less.  Since the bending stress generated in both transparent protecting layer 3 and card base material 6 when the card is bent, is almost equal, the stress acting upon the corner part of the recessed part 7 of the card base material 6, in which the optically recording member 5 is embedded, is reduced, so that the antibending strength of the card is increased.

Abstract: PURPOSE:To shorten the measuring time by supporting various kinds of objects to be tested suitably and automatically selecting a detecting position of a measuring chamber communicating with a concentration-measuring device in accordance with a shape of the object to be tested. CONSTITUTION:A fuel tank FT to be tested is arranged between boxes 10 and 20. Opening ends of the boxes are butted to each other to define a measuring chamber. A plurality of detecting members 80, 90 for supporting a contact element in a movable manner to the object to be tested are set inside at least one of the boxes. When the contact element is separated from the object to be tested, the communication of the measuring chamber and a concentration- measuring device 5 is shut by a communication-switching means. When the contact element comes into touch with the object to be tested, the measuring chamber is communicated with the concentration-measuring device. Therefore, each detecting member supports the object to be tested and at the same time, functions to connect the measuring chamber with the concentration-measuring device. A detecting position is automatically selected in accordance with a shape of the object to be tested.
