Title: Ink injection device
Inventor: SUGAWARA HIROTO
IPC: B41J2/045
Filed: 1993-10-20
Abstract: PURPOSE:To easily form an electrode and enhance the reliability by forming a wall of polarized piezoelectric ceramic and providing both an ink liquid chamber and an electrode which generates an electric field orthogonal to the polarization direction of the wall by a part of the wall. CONSTITUTION:When an ink liquid chamber 112b is selected according to the desired printing data, negative driving voltage is rapidly impressed to an electrode 113c and electrodes 113b, 113d are grounded. Since the specific permittivity of air filled in the insides of split grooves 116 is very small in comparison with piezoelectric ceramic in the upside of side walls 111 in which the split grooves 116 of side walls 111b, 111c are formed, electric field does not almost act on piezoelectric ceramic. Thereby a driving electric field acts on only the lower parts of the side walls 111d, 111c. The side walls 111b, 111c are rapidly deformed in the direction of the inside of the ink liquid chamber 112b by piezoelectric thickness sliding effect because the driving electric field is orthogonal to the polarization direction 4.

Title: Controller for instruction cache memory
Inventor: NISHIKAWA KOJI
IPC: G06F12/08
Filed: 1988-10-18
Abstract: PURPOSE:To take an instruction out of a rewritten data area with no reference to a main storage by rewriting the contents of an instruction cache memory as well as the contents of a data cache memory. CONSTITUTION:When the computing result stored in a register 20 is written into a data cache memory 5a, the instruction given from an instruction cache memory 2a is discontinued. Then an access is given to a D data address array 17b of the memory 5a and therefore the contents of the register 20 are written into a designated area of a D data array 19b. At the same time, the contents of the register 20 are written into an I data array 19a of the memory 2a via an operand address at the cache hit. Thus in case an instruction corresponding to the rewritten area of the array 19b is taken out hereafter, the relevant instruction can be taken out via the array 19a with no access given to a main storage. In such a way, the instructions can be taken out at a high speed.

Title: Sheet feeding device
Inventor: YASUKAWA YUKIO
IPC: B65H3/06
Filed: 1986-11-04
Abstract: PURPOSE:To make it possible to deliver securely sheet by sheet, by making the sheet conveying speed of a sheet feeding/conveying body slower than that of a printing device, and delaying the feeding timing of the next sheet at the difference of the conveying speeds, in a printer or the like. CONSTITUTION:Papers P set on a sheet feeding table 113 are squeezed to a sheet feeding roller 85 by a spring 111, separated by a separating pawl 115 by the rotation of the roller 85, delivered to a printing device 1 sheet by sheet at a speed Vf, held between a platen 19 and a pressure roller 33, and fed at the conveying speed Vp of the platen 19 hereafter. In this case, since the relation of the speed is set as Vp>Vf, the sheet feeding roller 85 is rotated by pulling of the papers P. Therefore, the speed to rate a gear 107 through a gear 89 is faster than the speed to rotate the gear 107 by pushing the left end 109L of a groove 109 by a connecting pin 105, resulting in the connecting pin separated, and the sheet feeding roller 85 starts to feed the next sheet slower at the difference of the both speeds. In such a way, sheets can be delivered securely sheet by sheet at an interval.

Title: Editing device and edited signal decoding device
Inventor: SHIMODA KENJI
IPC: H04N5/91
Filed: 1992-09-30
Abstract: PURPOSE:To prevent the disorder of a picture at an editing point. CONSTITUTION:A header extraction circuit 40 extracts an edited header from an edited signal. An edited signal is decoded by a variable length decoding circuit 42, a reverse quantization circuit 43, and a reverse DCT circuit 47, and the decoded output is outputted through a switch 44. In the case that it is shown by the edited header that a frame after the editing point is compressed between frames, the switch 44 selects the output for displaying a substitutional picture from a constant picture circuit 50 instead of the output of the reverse DCT circuit 47. Thus, even in the case that data after the editing point are interframe data, the picture can be prevented from being disordered at the editing point.
