Title: Ink-jet recording device
Inventor: SATO KOICHI
IPC: B41J2/175
Filed: 1988-06-07
Abstract: PURPOSE:To supply ink positively, and to conduct the excellent operation of recording without damaging even the effect of bubble retention by forming a bubble retention section to at least a part of an ink feed path to a recording head from an ink storage section and installing a branch path bypassing the bubble retention section. CONSTITUTION:When ink is filled, bubbles stay in a section 3-3. A bubble retention section fills the role of the absorption of an impact in the direction of a multi-nozzle 3-2 from the rear (the ink feed path side) at the time of head scanning and the absorption of pressure to the rear at the time of discharge-that is, in the direction of an ink feed path 3-4 from the multi-nozzle 3-2. When a majority of bubbles stay in the section 3-3, the supply of ink is often interrupted, but normal setting can be executed because ink is fed by a second feed path 3-5 even in this case, and an effect as the pressure absorber of bubbles in the section 3-3 is not damaged. It is preferable that the second feed path 3-5 is formed in structure, in which bubbles are difficult to stay, by the constitution of an extremely smooth curve shape, etc. at that time.

Title: Elastic surface wave matched filter, receiver using the same and communications system
Inventor: YOKOTA AKANE
IPC: H03H9/42
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To eliminate an input signal component that operates as a noise component and to obtain a stable output peak signal by arranging 1st and 2nd output IDTs, so that the phases of elastic surface wave which is inputted to both are reverse to each other and taking out the differential outputs of both output peak signals. SOLUTION: Because elastic surface wave signals which are separately excited by input IDTs 112 and 111 become reverse phases to each other, and in output peak signals which are acquired by output IDTs 132 and 131, their phases are mutually inverted. Input signal components which operate as noise components come directly from a bonding wire 1211 for an input signal to bonding wires 1221 and 1231 for an output signal. However, an input signal component of a noise component can be eliminated by getting a differential output of the output peak signals of both output IDTs 132 and 131 by using a converter 161. With this, it is used as an synchronization detecting element, the jittter of a synchronization signal is reduced, the synchronous acquisition of a code and a clock becomes accurate and reliability is improved.

IPC: C08L55/00
Filed: 1979-10-29
Abstract: PURPOSE: To prepare a resin composition having excellent surface matting effect without lowering the moldability and physical properties, by using a composition of a specific terpolymer and a block copolymer as a main component.  
     CONSTITUTION: 100pts.wt. of a copolymer of an aliphatic vinyl compound, a conjugated diene compound and an aromatic vinyl compound, is blended with 3W 20pts.wt. of a block copolymer of an aromatic vinyl compound and a conjugated diene compound, containing 50W90wt% of the conjugated diene unit and having carboxyl groups at the terminals of the molecular chain. The block copolymer can be prepared by reacting CO 2  with the terminal Li of a copolymer obtained by the anionic polymerization of the above monomers using an organic Li compound as a catalyst, thereby carboxylating the terminal of the copolymer. Higher content of the terminal carboxyl groups results in higher matt effect.

Title: Control method of operating excavator for pile driving
Inventor: MIZUNO TOSHIYUKI
IPC: E02D5/34
Filed: 1982-08-09
Abstract: PURPOSE:To reduce the number of workers necessary for watching the conditions of pile construction all the time by a method in which the actual load of an excavator blade is compared with a set load for the excavator blade when cement mortar, etc., is injected, and the drawing speed of the excavator blade or the speed of an injection pump for cement mortar, etc., is controlled. CONSTITUTION:The actual load of an excavator blade, measured by a load meter 9 provided to the hanging part 8 of the excavator blade, is compared with a set load for the excavator blade when cement mortar, etc., is injected. The drawing speed of the excavator blade or the speed of an injection pump for cement mortar, etc., is controlled on the basis of the compared results. For example, when the head 1a of an earth auger 1 is higher than the injection height of cement mortar and a space is formed between the head 1a and the cement mortar, the actual load shown by the measuring signal A of the load meter 9 becomes heavier than a set load value (alpha) because the buoyance of the cement mortar does not work. The compared results of both the load values to be compared by a comparator circuit 18 are sent as output signal B to a recorder 19, etc., and displayed there. Accordingly, on the basis of the compared results, the drawing speed of the earth auger 1 or the rotation of the injection pump for cement mortar is adjusted by an operator.
