Title: First-in/first-out type memory
Inventor: SAKAKIBARA JUNICHI
IPC: G06F5/06
Filed: 1984-10-12
Abstract: PURPOSE:To attain a first-in/first-out (FIFO) type memory of a high speed and large capacity by applying a system where data are written and read to the RAM addresses in the ascending order and therefore using a RAM in place of a transfer register. CONSTITUTION:The data supplied from outside via a signal line 105 are latched by an input register 17. Thus the data given from a control circuit 19 cannot be supplied and the data of the register 17 are written to a RAM11 via an address counter 12. Thus the input of data is possible again with a signal line 102. When a writing action is over, an up-down counter 14 is counted up. Then a maximum value detecting circuit 15 checks whether the buffer of the RAM11 is filled up or not. If the buffer is filled up, an input unable state is set. While the output on a signal line 106 is set under an unable state when it is decided by a minimum value detecting circuit that no data to be read out exists.

Title: Ink jet printer
Inventor: MINEMOTO HITOSHI
IPC: B41J2/385
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To stably discharge coloring material particles even if no discharge time is continued for a long time by judging the lapse time from when the applied voltage to a discharge electrode is turned off by OFF time judging means, and varying the applied voltage to the discharge electrode in response to the time judged by the judging means. SOLUTION: A control circuit 44 decides the discharge voltage Vb to be given to the discharge electrode 64 in response to print information 30a, and outputs it as a print signal 44a to a voltage applying circuit 42. OFF time judging means 40 extracts the lapse time T from the information 30a. The circuit 44 applies a moving voltage Vc before the voltage Vb is applied when the lapse time is judged to be a predetermined time or more. Since the coloring material particles 58 are moved to the end 641 of the discharge voltage 64 by the voltage Vc but regulated to the degree that the particles 58 are not flown as particle group 59, the particles 58 are moved to the end 641 of the electrode 64. Thereafter, the voltage Vb is applied to the electrode 64 but at this time the particles 58 are concentrated at the end 641 of the electrode 64, and hence they fly without delay.

As the vinyl monomer, a monomer different from the monomer component which constitutes the main chain of the macromer is preferably used for the purpose of the formation of a comb-shaped copolymer.

Filed: 1989-08-22
Abstract: PURPOSE:To even hardness by repeating pressurizing and depressurizing by a unit of block composed of a specified number of disk-formed sheet-like members, and manufacturing a lamination roll by the unit of block. CONSTITUTION:Flanges 5 are fixed to a shaft main body 2 provided with fine ports on an outer periphery thereof, while a block made by superposing a specified number of sheet materials 1 is inserted in the shaft main body 2. Pressurizing and depressurizing are excerted thereon in order to recover the compression to a certain extent and attain a temporary tightening condition. Temporary tightening of the block is succeedingly performed several times. The compression is not recovered even under a depressurized condition, which is a reference condition where the first block reaches preset hardness. Against the reference, then the compression processing ratio of the next block is determined. A number of blocks are sequantially processed with the compression ratio. The final block is press-fitted by pressurizing through a guide post 6 provided on the shaft main body 2, and a locking nut 7 is screwed thereon for terminating the manufacture.

Title: Manufacture of fine electrode
Inventor: MIURA AKIRA
IPC: H01L21/28
Filed: 1989-08-22
Abstract: PURPOSE:To allow the tip of an electrode to be sharpened by laminating the first metal and the second metal as the electrode in order and arranging a conductor slightly above a polygonal cone to apply an electric field between the second metal and the conductor while heating the first metal. CONSTITUTION:A silicon board 1 has conical protrusion formed and turned into SiO2 by means of thermal oxidation. The protrusion is covered to form the first metal 12 made of Pt, e.g. and the first metal 12 is covered to form the second metal (W) 13, and a conductor 4 is formed slightly above the protrusion. Then a current is carried from a power supply to the Pt for heating them. As a result, a temperature in the vicinity of the tip of the protrusion is higher. When hundreds voltage is applied in between the W and the conductor 4 which are spaced at a few mum in such a state, the atoms of the second metal (W) 13 are attracted to electric field and moved to the tip rolling over and over to sharpen the W into a pyramid so that the tip of the electrode 2 can be sharpened even in atomic units. It is thus possible to obtain a sharp-tip fine electrode 2.
