Title: Ink jet head
Inventor: KINOSHITA MASATOSHI
IPC: B41J2/045
Filed: 1992-02-19
Abstract: PURPOSE:To shorten a bonding time and enhance a mass productivity by a method wherein positioning pins longer than a flow path are embedded in flow paths on the both sides, and the both ends of the positioning pins are used for positioning a nozzle plate and an ink supply means. CONSTITUTION:In a set of three substrates, i.e. a center piezoelectric substrate 1, and upper and lower piezoelectric substrates 2, the center piezoelectric substrate 1 is approximately twice larger in thickness than the upper and lower piezoelectric substrates 2 and longer in the direction of a flow path by the length for leading electrodes outside. The respective piezoelectric substrates are polarized by providing electrodes on the upper and lower surfaces thereof. When grooves serving as flow paths are formed on the polarized piezoelectric substrates, grooves are formed on the upper and lower surfaces of the center piezoelectric substrate 1 and on one surface of the upper and lower piezoelectric substrates. At this time, 34 grooves are formed for producing a head, e.g., having 32 nozzles in one line. The 1st and 34th nozzles are used for positioning. Positioning pins or plates 9 longer than a flow path are embedded in the positioning grooves. The piezoelectric substrates are boded to each other through an adhesive applied on the adhesive surfaces thereof. Ink supply paths are formed on the upper and lower substrates 2 by cutting. A nozzle plate is attached all over the flow paths.

CONSTITUTION:A light beam radiated from a light source 3 such as a semiconductor laser, etc., is propagated through an optical waveguide layer 2, converted to parallel rays by a plane lens 4, and this parallel rays, first, are deflected by a surface acoustic wave 6 radiated from a surface acoustic wave electrode 5, also condensed by a plane lens 8, and reaches a photodetector array 11. On the detector array, the position of a converging point of a converging beam 10 is proportional to the frequency of an electric signal applied to the surface acoustic wave electrode 5, but this operation is the operation of an optical spectrum analyzer. Subsequently, a part of a light beam deflected by the surface acoustic wave 6 is reflected by a waveguide type light beam splitter 7, and this reflected light beam is deflected again by a surface acoustic wave 13 radiated from a surface acoustic wave electrode 12. This deflected light is converged again by a plane lens 14 and reaches on a photodetector 15.

Title: Obstacle evading route searching method for mobile object
Inventor: TAKENAKA TORU
IPC: B25J13/00
Filed: 1993-01-28
Abstract: PURPOSE:To quickly decide a route to reach a target by setting virtually a viscous resistance coefficient distribution that is reduced as the distance increases from an obstacle or a mobile object and searching the route of the mobile object based on a variational principle as an extreme value problem of a universal function of the time, the energy, etc., needed for movement of the mobile object. CONSTITUTION:A moble object 10 arrives at its target point while evading the obstacles 12 and deciding a route 14. In an environmental map, a virtual viscous resistance coefficient distribution is prepared for each obstacle 12 in a form of contour lines. This coefficient distribution is monotonously reduced as the distance increases from the obstacle 12. The route 14 is decided so as to be locally minimized based on a variational principle, i.e., in a form where the basic physical rule is shown as an extreme value problem of a universal function. Thus, it is possible to quickly decide a smooth and useless route of the object 10.

Title: Method of sintering operation
Inventor: SATO KAZUAKI
IPC: C22B1/20
Filed: 1985-02-21
Abstract: PURPOSE:To make uniform the calcination in the transverse direction of a pallet in a DL sintering machine by changing the piling shape and gain size distribution of the raw material in an ore feed hopper so that the temp. of the sintering ore is uniformly distributed in the transverse direction of the pallet. CONSTITUTION:Compounded sintering raw material is charged into the ore feed hopper 3 and is charged onto the pallet 6 by a reciprocating conveyor 1 moving in the transverse direction of the pallet 6. The material is then ignited and is conveyed to an ore discharge part. Sintered ore 11 falls in the form of lumps in the ore discharge part. The temp. at the section of the sintered ore in the terminal part of the pallet is measured by a thermometer 8 and the temp. distribution in the transverse direction is detected by a speed calculator 9. The moving speed of the conveyor 1 is determined in accordance with the temp. distribution and the speed value is inputted to a speed control device 2, by which the above-mentioned moving speed is changed. More specifically, the grain size of the raw material is coarse or the packing density thereof is small in, for example, the low-temp. part and therefore the moving speed of the conveyor 1 in the stage of passing through the piling part of the raw material in the hopper 3 corresponding to the low-temp. part is lower than the moving speed in the other part. The piling shape of the raw material in the hopper is thus made into a projecting shape and the finely grained raw material is obtd.
