Title: Printer
Inventor: IGUCHI KOJI
IPC: B41J11/42
Filed: 1988-07-21
Abstract: PURPOSE:To correct a line feed pitch accurately and increase the accuracy of a printing position by seeking the distance between mark intervals of printing paper to be transported and correcting the line feed printing interval in accordance with the ratio of the obtained mark interval distance and a theoretical value. CONSTITUTION:Marks 11 on the printing paper 3 to be transported by a transport device 9 are detected by a detection device 10, and the interval between the first mark and another mark that follows is measured by a counting device 12 using clock pulses. Then the number of clock pulses in the interval of lines to be corrected is calculated using an arithmetic/logic operation device 13 based on the measured number of clock pulses, the specified number of lines, printing size setting, the established number of clock pulses corresponding to the specified interval between the marks 11 and the established number of clocks for interval between lines. The line feed pitch for a printing process that follows is selected depending upon the calculated number of clock pulses in the interval between printing lines. Consequently, the misalignment of line feed is accurately corrected.

Title: Method for molding thermoplastic resin foam
Inventor: YAMAGUCHI KENJI
IPC: B29K105/04
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To prevent steam holes from being blocked and improve the productivity of a foam by a method wherein forming methods containing no vacuum cooling are included midway through the repeated and continuous formings of thermoplastic resin foams. SOLUTION: Steam holes 3 are provided on the portions facing to a cavity of a male mold 1a and of a female mold 1b. Through steam valves 11, a steam is introduced in a steam chamber 4 so as to heat and fuse resin beads in the cavity through the steam holes 3. Next, after the mold 1 is cooled with cooling water nozzle 5, the steam chamber 4 is evacuated with sucking means 40 so as to quickly vacuum-cool the mold 1. After that, a formed body B is taken out of the mold 1. In this case, in order to prevent the steam holes 3 from being clogged, after the predetermined number of continuous shots, this vacuum forming is executed without evacuating the steam chamber 4 at cooling by discharging cooling water through drain tubes 20 and then the formed body is allowed to cool.  As a result, during the continuous forming, an inorganic matter lift in the steam holes is also washed away together with the efflux of the cooling water.

Title: Pneumatic tire
Inventor: DOBASHI HIDEYUKI
IPC: B60C15/06
Filed: 1993-07-23
Abstract: PURPOSE:To suppress the vehicle noise (inter-vehicle sounds) without being followed by a deterioration in the steering stability. CONSTITUTION:A hard rubber chafer 8 disposed for suppressing the volume of a hard rubber filler 7 surrounded by a carcass 5 and its up-wound portion 6 and disposed at a position corresponding to a rim flange located axially outwardly from the carcass up-wound portion 6 is increased in thickness from the radially inner side toward the radially outer side, and a thickest portion thereof is provided at a rim flange upper-end portion that is flared axially outwardly. Therefore, the rigidity of a side wall 2 is less influenced with respect to the vertical or radial deformation. When, on the other hand, the side wall 2 receives an axial external force in a condition of being vertically load deformed, the thick-walled portion of the rubber chafer supported by the up- wound portion of the carcass ply advantageously suppresses the deformation of the side wall in cooperation with the upper end portion of the curved rim flange. This enables the reduction in the inter-vehicle sounds without the steering stability being impaired.

Title: Measuring method for displacement of diaphragm in liquid discharge head provided with diaphragm
Inventor: HAYASHIZAKI KIMIYUKI
IPC: B41J2/175
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring method in which a displacement up to an attenuation state is measured on the basis of a sudden change in a diaphragm installed at a liquid discharge head by a method wherein a displacement in one point on the diaphragm and a prescribed displacement amount in which a displacement amount obtained regarding every diaphragm out of a plurality of diaphragms are compared with a prescribed displacement amount which is decided in advance. SOLUTION: When a manual measurement is decided, the initial position of a diaphragm is first confirmed. After that, the measurement is performed along a movement point which is decided in advance by a user. On the other hand, when an automatic measurement is selected, a host computer makes the user confirm the initial position of the diaphragm. After that, the measurement is performed along a measuring point which is decided in advance by the user. When the initial position is displaced due to the mounting operation of a jig or due to an irregularity in the manufacture of a liquid discharge head, the position of a stage is corrected on the side of the user. In this state, a displacement measuring apparatus sequentially measures a plurality of diaphragms constituted on the liquid discharge head. When it reaches a final point, measured data is transferred to the host computer from a converter 11. The host computer judges the displacement amount of every diaphragm on the basis of the data.
