Title: Assembling method of inkjet head
Inventor: YASUHARA MASATOSHI
IPC: B41J2/16
Filed: 1988-04-19
Abstract: PURPOSE:To reduce the number of processes required for joining and to improve the reproducibility of said processes and the yield, by installing elements into each factor and fixing between said factors through ultrasonic welding. CONSTITUTION:A valve element 2 is sandwiched from opposite sides thereof by a pair of element holders 3a each using an energy director 3b. When ultrasonic wave is radiated, the energy directors 3b are melted, and therefore communicated with each other at the melting parts through a through-hole 2b formed in the valve element 2a. Thus, welding is completed. The valve element 2a is provided with a sliding part 4 and a stopper part 5. The sliding part 4 is slided by the pressure difference in an up-and-down direction of the valve element 2a. As a result of this, ink flows only in a normal direction 6 of the valve element 2a. When ultrasonic welding is carried out, the ultrasonic wave is radiated also onto the whole of the valve element 2a, and accordingly, the sliding part 4 of the valve element 2a having characteristic frequency several to several tens times of the welding ultrasonic wave is formed to vibrate. Therefore, the sliding part 4 is fixed by an electron wax 1 and then the welding operation is carried out. Thus, welding is completed without breaking the function of the valve.

The metal to be used for the passive state forming metal layers 2 is exemplified by, for example, Al, Ti, Cr, Co, Ni, Ta, Zr, etc. These metals oxidize rapidly in air and form the stable oxide film, i.e. passive films on the surface. The recording at a high rotating speed with a relatively low recording laser output is enabled in this way and the environmental resistance is simultaneously improved as well. High reliability is thus obtd.

Abstract: PURPOSE:To advance an inference in order to obtain a conclusion by deciding automatically the difference of conditions between the rule knowledges even though the complete coincidence is obtained between the accumulated rule knowledges and a given prior fact and correcting the rule most approximate to the prior fact. CONSTITUTION:A prior fact is inputted and stored in a prior fact storage means 1. Then the related rule knowledge is taken out of a rule knowledge storage 2 and collated with the contents of the storage 1. The trade-off relation satisfied between the rule knowledges is detected based on the contents of the storage 1. If a condition part is not completely coincident with the contents of the storage 1 at execution of an inference, the conditions are eased and added to the rule that is not conflicting with the prior fact based on the result of a trad-off relation detector 3. Then the rule knowledge is corrected and the inference is carried on. Thus it is possible to advance the inference and a proper conclusion is obtained even though the conditions of the accumulated rule knowledges are not completely coincident with the contents of given fact.

Abstract: PURPOSE:To reduce water pressure applied to the wall of embankment and make the wall in small thickness by placing caissons each having a plurality of chambers ring-shapedly at the sea ground, and introducing sea water so that the water level sinks gradually from the chamber nearer outside the embankment toward the one inside it. CONSTITUTION:Each caisson 1 is formed so that the top plate 3 lowers gradually from outside the embankment toward inside it, and such caissons 1 are put parallelly on sea ground so as to form a ring-shaped embankment. Sea water is introduced into chambers 7a-d in the caisson 1 so that the water level lowers from the chamber 7a at the outside of embankment toward the chamber 7d inside it. This lessens the water pressure applied to the walls of the caissons and bulkheads 6a, 6b, 6c inside it, which enables decreasing the wall thickness.

Filed: 1987-04-21
Abstract: PURPOSE:To prevent a decoder circuit from generating misselection which may be generated when the 1st line voltage exceeds the 1st power supply voltage by a prescribed value by connecting an element having characteristics of a diode between a 1st line connected to a NOR circuit and a 1st power supply. CONSTITUTION:An n-type MOSTR Qa1 is connected between the drains of n-type MOSTRs Q1-Qm and a power supply VCC. The gate and drain of the TR Qa1 are connected to the drains of the TRs Q1-Qm and its source is connected to the power supply VCC. When the voltage of a NOR node 11 exceeds VCC+VT, current is allowed to flow into the NOR node 11 side to prevent the voltage of the NOR node 11 from exceeding the voltage VCC+VT. As the result, the TR Qa1 acts as a diode. Consequently, the decoder circuit can be prevented from generating misselection which may be generated when the 1st line voltage exceeds the 1st power supply voltage by the prescribed value.

Inventor: KOKADO SEIYA
IPC: B41F21/00
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To eliminate a hindrance due to collision of-a cam with a cam follower. SOLUTION: A cam is composed of plate cams 41 of a high strength material and a plate cam 43 of an elastic member. The plate cam 43 has a shape projecting from the plate cams 41 and therefore a cam follower 3 comes into contact with the plate cam 43 before it comes into contact with the plate cams 41. The shape of the plate cam 43 changes due to a force of impact and thereby it absorbs an impact load. When the cam follower 3 comes closer to the cam, a part of the plate cam 43 is changed in the shape by being pressed thereby and the cam follower 3 comes into contact with the lateral sides 41a of the plate cams 41. The cam follower 3 moves along the shapes of the plate cams 41.
