Title: Timing correction circuit
Inventor: MAEDA TORU
IPC: G06F1/04
Filed: 1985-04-03
Abstract: PURPOSE:To give easily the optimum access timing to a peripheral device of a microcomputer by shifting directly the control signal through a shift register synchronizing with a clock signal or using another shifted signal. CONSTITUTION:The holding time of the write information has no margin if both an access signal 9 and an R/W synchronizing signal 2 are written at a time. The output QH or QD is defined as a correction signal 11 among those outputs 10 (QA-QH) that shifted 10 the R/W signal at the rise of a clock signal 1. Then an AND 5 is secured between the signal 2 and the signal 11. The rise edge 13 of the signal 2 is corrected 12 previously to secure an AND 6 with the R/W signal 3. Then an access synchronizing signal 9 of the write mode is delivered via an OR circuit 8 after separation from the road mode. This produced the margin of the write timing. In such a way, the synchronizing correction is possible with complete synchronization with a basic clock. This improves the working reliability of a timing correction circuit.

Title: Printer
Inventor: KENTO DEI BINSENTO
IPC: B41J25/308
Filed: 1989-03-20
Abstract: PURPOSE: To minimize the dislocation of distance causing a misalignment of printed characters by correctly maintaining a distance between a pen and paper, and flatness of paper during printing. CONSTITUTION: When paper 5 is subjected to print, a spacer 21 slides crossing over the print surface of paper. Since the spacer 21 is situated proximate to a printing area, it serves to flatten paper at the local region of printing. In order to flatten paper 15, force implied by the spacer 25 can be referred to 'contact force'. The contact force is decided by an ink jet pen 11 relative to a guide rod 20 and weight distribution of a carriage 13. Namely, the carriage 13 operates, as anticlockwise contact force maintains the surface on which the spacer 25 rides in contact with the surface of paper 15, to secure substantial paper flatness under the ink jet nozzle causing no excessive friction trapping.

Title: Work roll machining device for cold rolling
Inventor: IMAI HIROFUMI
IPC: B23K26/00
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To control variance of the depth of holes formed on a roll and to prolong the rolling life of the roll by providing a 'spatula' and/or a rotary electric grinder adjacently to the machining head that produces multiple holes on the roll surface with a pulsed laser beam and uniformizing matters sticking to the roll surface before the formation of the holes. SOLUTION: A means for uniformizing matters sticking to the surface of a roll 1a is constituted of a 'spatula' 2 for removing large deposits and a uniformizing part 3 for spreading a residual oil film or the like. For example, the 'spatula', which is a plate-like part made of 'Teflon(R)' with a thickness of 5 mm and a width of 100 mm, is installed on the roll 1 in the manner of being applied to the roll 1 at a measured angle of 50 deg. from the roll 1 surface. In addition, the uniformizing part 3 is such that, using a rotary electric grinder for waxing an automobile, a disk is rotated provided with a diameter of 200 mm and covered with a sponge-like outer skin.  The variance of the depth of machined holes on the roll, whose surface is uniformized by this means, is improved from the conventional 50% or so to 10% or less, with the life of the roll also improved within a similar range of about 10%.

Title: Massage machine
Inventor: YOSHIDA MITSUTAKA
IPC: A61H15/00
Filed: 1990-03-19
Abstract: PURPOSE:To constitute the massage machine so that it has durability, and also, can execute simultaneously both of a rolling massage by a massage body and a rubbing massage by a rubbing body by forming the outside peripheral part of the rubbing body and the outside peripheral part of the massage body to the same face or almost the same face. CONSTITUTION:Between a pair of massage bodies 6 being rotatable around a driving axis center P, a pair of rubbing bodies 8 are provided, and the respective rubbing parts 17 are placed relatively so as to approach and be separated gradually each other along the periphery of the driving axis center P, therefore, by a rotation of the massage bodies 6, a pair of rubbing bodies 8 execute mutually a far and near motion in the direction of the driving axis center P, and a rubbing massage is executed between a pair of rubbing parts 17. Also, in this constitution, the outside peripheral part of the rubbing body 8 and the outside peripheral part of the massage body 8 are formed to the same face or almost the same face. Accordingly, for instance, when the scruff of the neck is positioned between a pair of rubbing parts 17, while rubbing the scruff of the neck by the rubbing parts 17, simultaneously a rolling massage can be executed to a shoulder abutting on the massage bodies 6. In this case, since a weight load to a massage machine 1 can be dispersed and burdened, the durability is also enhanced.

Title: Nonvolatile semiconductor memory device
Inventor: KATO HIDEO
IPC: G01R31/28
Filed: 1993-03-29
Abstract: PURPOSE:To comfirm the proper operation of a memory cell in an over-erasing state. CONSTITUTION:In a teste mode, sources of respective cells are held at the ground level without selecting any of row line by a row decoder 23, as well. When an over-erased memory cell is present, the cell is allowed to be conductive according to the depression since the cell is depressed, thus the presence of the over-erased memory cell is detected by potential change based on the conduction on row lines. Besides, a means for the source bias is arranged so that the test potential suitable for the test are applied to each cell. Thus, a threshold value shifted faultly to the (positive) direction of the cell is detected. Thus, the over-erase state is detected more properly. Furthermore, the access of a high speed is obtained after the threshold value of the memory cell having the fastest erasure is erased until it is arrived to a predetermined value.

Abstract: PURPOSE:To improve the life of laser oscillation, developing a perhalogenide from an organic solvent of a dye laser wherein the laser oscillation is generated by excitation with energy applied to a laser dye solution containing an organic dyestuff and an organic solvent. CONSTITUTION:As a perhalogenide, the following are used: a total halogen substitution hydrocarbon group of perfluorohexan, perfluoroheptane, etc., and an alcohol group in which all of the C-H bonds of pentafluoroethanol and the like are converted into the C-X bonds. As a dyestuff, the following are used: rhodamine 6G, rhodamine B, phenyl biphenyl oxadiazole (PBD), etc. A laser dye solution is stored in a solution trap 2, and circulated in the direction of an arrow by a pump 1. An oscillated or amplified laser light 3 by an excitation light 5 is output. In the case where hexafluoroacetone solution of rhodamine 6G 5X10<-3>mol/l for example, is applied to the dye solution, the period when the laser output decreases up to 50% of an initial reference value is 1000 hr. Thus a dye laser whose life is remarkably improved can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a method for constructing a cast-in-site pile which can provide a large frictional force easily irrespective of ground conditions. SOLUTION: A hole 4 is drilled in the ground 2 to a depth matching the length of a pile to be constructed. Next, an injection pipe 6 is located at the center of the cross section of the hole 4, and the lower end of the injection pipe 6 is located near the bottom 402 of the hole 4.

The first cement milk 12 is left for one or two days and hardened, and before it is completely hardened, i.e., before initial strength of the first cement milk 12 is obtained, second cement milk 16 is supplied into the injection pipe 6 and is pressed from a filler port 10 into the first cement milk 12 as pressure is gradually increased.  Therefore, the first cement milk 12 more or less hardened is gradually broadened, whereby an increased diameter part 18 larger in diameter than other parts is formed.
