Title: Polishing method
Inventor: EHANA YOZO
IPC: B24B37/005
Filed: 1984-11-30
Abstract: PURPOSE:To prevent a part to be polished from generating on its polished surface a fine flaw, by increasing before stopping a rotation the reverse pressure of a cylinder larger than that when the part is polished and decreasing a polishing pressure applied to an upper polishing plate. CONSTITUTION:A glass surface plate 2, being a part to be polished, is set to a hole in a carrier 1, and the glass surface plate 2 is held between upper and bottom polishing plates 3, 4. The upper polishing plate 3 is connected with a working rod of an air cylinder 6 fixed to a vertically moving plate 5. The air cylinder 6, decreasing its upper pressure A to zero while increasing its bottom pressure B to be applied and applying the reverse pressure, regulates a polishing pressure by adjusting weight applied to the glass surface plate 2 from the upper polishing plate 3. And if the air cylinder 6 increases its bottom pressure B larger than that in polishing when the bottom polishing plate 4 is stopped, the air cylinder 6, lifting the upper polishing plate 3, reduces the polishing pressure. Consequently, the glass surface plate 2 enables its polished surface to be prevented from finely flawing.

Title: Liquid crystal display device
Inventor: YOSHIMOTO HATAAKI
IPC: G02F1/136
Filed: 1989-09-29
Abstract: PURPOSE:To obtain the liquid crystal display device having a high luminance and scarcely causing a crosstalk by setting an interval between a picture element electrode and a signal electrode so as to become shorter than thickness of a varistor. CONSTITUTION:An interval l1 between a picture element electrode 3 and a signal electrode 4 is shorter than thickness l2 of a varistor 5. A varistor voltage between the signal electrode 4 and the tip of the varistor 5 is higher than a varistor voltage between the signal electrode 4 and the picture element electrode 3, therefore, it does not occur that a current flows to a scanning electrode 7 on a second substrate through the tip part of the varistor 5 from the signal electrode 4. Accordingly, a normal matrix circuit of a liquid crystal and the varistor 5 is formed, and no variance is generated in the contrast of each picture element. In such a way, the normal matrix circuit of the liquid crystal and the varistor is formed and the display having a high luminance and a high contrast can be executed.

Title: Image data processor
Inventor: OKAMOTO SHIRO
IPC: G03G15/01
Filed: 1986-10-23
Abstract: PURPOSE:To precisely reproduce a single color through a simple operation and to save coloring materials by controlling a specific color, the sequence or a sequence controller based on the data about the levels of plural color components and their ratio. CONSTITUTION:Based on the ratio of data about plural colors apart from the specific color, specific coloring is carried on. When a controller 63 detects that almost all pieces of image data Y', M' and C' (41-43) are smaller than some threshold L through an I/O port 62, the controller 63 instructs a printer part to limit an image forming process to one black color. If only the data Y' is smaller than the threshold L and the others are larger, they are regarded as a single color of a component Y. A control signal is outputted to the controller 63 so that a printout in one color corresponding to the component Y can be available. Even if some component of the entire picture of an original exceeds the threshold L but negligible, the controller 63 regards it as a black one and processes it similarly.

Title: Structure of underground tank
Inventor: SHIMIZU TORU
IPC: E21D13/00
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To avoid dense arrangement of reinforcements even when a side wall and a bottom plate are rigidly connected, by forming a polyhedral underground tank of which the under face of the bottom slab projects downward. SOLUTION: This underground tank is a hydraulic pressure-resistant slab type reinforced concrete tank provided with a bottom slab 1 which can withstand and underground water pressure. When constructing it, a continuous underground wall 2 is constructed first in the periphery of the construction site to cut off water. Then, the site surrounded by the continuous underground wall 2 is excavated down to the under face of the bottom slab 1. Then, concrete is placed for the bottom slab 1 and the side wall 3. The side wall 3 and the bottom slab 1 are rigidly connected to each other without joints between them. The bottom slab 1 is so shaped that the under face 5 projects down. That is, the central part is projected down most to form many slope faces at the periphery. Accordingly, the under face 5 has such a shape that the spherical surface is combinedly constituted of many planes.  In this way, the flow of stresses in the fitting part of the side wall 3 and the bottom slab 1 is made smooth and hence, excessive bending moment generating in the structure is moderated.

IPC: B41J25/308
Filed: 1989-09-28
Abstract: PURPOSE:To stably set a proper printing gap value by a method wherein a planetary gear is separably set between a plurality of gears, the planetary gear is pressed by a spring in a gear engaging direction, and a power transmission is released by the planetary gear. CONSTITUTION:At the time of a printing gap adjustment, a gap adjusting motor 8 rotates a main shaft 3 through an idle gear 7, a planetary gear 6, an idle gear 5, and a shaft drive gear 4 to move a carrier frame 9 forward and backward. At this time, the planetary gear 6 is pressed on the idle gear 5 with a predetermined tensile force by a tension spring 10 to conduct a power transmission. In this manner, a gap adjusting arm 1 formed integrally with the carrier frame 9 abuts against a platen 2 as the carrier frame 9 moves toward the platen 2 to serve as a stopper. The abutting position at this time is used as a reference in a paper thickness detection. After that, a reverse load when the gap adjusting arm 1 comes into contact with the platen 2 becomes larger than the tensile force of the tension spring 10, and the teeth of the planetary gear 6 are skipped, which results in the release of the power transmission.

Abstract: PROBLEM TO BE SOLVED: To make an empty beverage container crushable by hand and deformtive to a great extent by crushing and also to make a condition for being deformative discernible. SOLUTION: After a rib-equipped cap 1 having a rib 1e and a groove 1c at its cap-side spiral protuberance 1a is screwed down onto a beverage cotainer having a protuberance 2c at its spout-side spiral protuberance 2b, the rib- equipped cap 1 is loosened slightly, making the protuberance 2c and the groove 1b engaged with each other, and thereby the beverage container is tightly closed with an opening of a spout 2a closed with the rib 1e. However, as a force is applied to the beverage container by crushing the container by hand, the rib-equipped cap 1 is pushed up and air inside the beverage container is discharged to the outside. Furthermore, a change in the states before and after the engagement of the protuberance 2c and the groove 1b can be discerned certainly by a looseness in the state of the rib-equipped cap, the beverage container can be crushed without fail for disposal.

IPC: B01D33/048
Filed: 1988-10-07
Abstract: PURPOSE: To squeeze material without applying a bending effect on squeezing rollers by disposing a plurality of squeezing rollers on rigid roller races enclosing a drum apart prescribed spacings and passing filtering webs between the drum and the squeezing rollers. CONSTITUTION: This press-filter is provided with the draining drum 8 and the many squeezing rollers 52 coupled to each other so as to form a chain between the curved rigid roller races 48a to 48b. The filtering webs 16, 24 including the material 90 to be drained pass between the drum 38 and the many squeezing rollers 52. The curving of the rigid roller races 48a to 48b is so formed that the spacing 1 between the drum 38 and the squeezing rollers 52 decreases during rotation. As the material 90 advances forward, the material is gradually compressed and is compressed by receiving the shearing effect every time the material passes the squeezing rollers 52. At this time, the squeezing rollers 52 are supported by the rigid roller races 48a to 48b and are capable of withstanding the pressure at the time of squeezing the material 90 without receiving the bending effect.
