Title: Controller for engagement pressure of friction element
Inventor: KATO YOSHIAKI
IPC: G05B11/36
Filed: 1992-07-16
Abstract: PURPOSE:To allow the control gain of friction element engagement pressure to match the required engaged states of friction elements by varying the control gain with the low and high pressure regions of the engagement pressure. CONSTITUTION:A valve 6 determines control pressure Ps in accordance with a duty ratio D. A selector valve 11 does not output gain changing pressure Pg as long as the control pressure Ps is in a low region less than a set value. While the control pressure is in the low region, an engagement pressure control valve 7 varies engagement pressure Po at a small gain which corresponds only to the control pressure Ps delivered to a chamber 7b. When the control pressure Ps enters a high region in excess of the set value, the selector valve 11 produces the gain changing pressure Pg. The gain changing pressure Pg increases the force to energize a spool 8 leftward in Figure, so that the engagement pressure Po is controlled at a high gain.

Title: Production of cyclopentanone
Inventor: TAKEHIRA KATSUOMI
IPC: B01J27/00
Filed: 1983-10-11
Abstract: PURPOSE:To produce the titled compound useful as a raw material of monomers of synthetic polymers such as sebacic acid for the production of 6,10-nylon, economically, by efficiently oxidizing cyclopentene with a peroxide in liquid phase in the presence of a noble metal catalyst. CONSTITUTION:Cyclopentanone is produced by the oxidation of cyclopentene with a peroxide such as hydrogen peroxide, tert-butyl hydroperoxide, etc. in liquid phase, i.e. in an organic solvent such as alcohol, ether, ketone, ester, etc., in the presence of a noble metal catalyst such as palladium, rhodium, platinum, iridium, etc. Cyclopentene used as a raw material can be produced economically in high yield by the partial hydrogenation of cycloepentadiene existing abundantly in the 5C fraction of the naphtha cracking mixture. The peroxides exemplified above are advantageous from practical point of view because the former compound forms water as by-product and the latter compound is soluble completely in an organic reagent and is stable.

Title: Printing head
Inventor: KIMURA KOICHI
IPC: B41J2/275
Filed: 1988-07-29
Abstract: PURPOSE:To obtain the uniform return of each of printing levers by excluding the close contact state between the movable yoke part of each of the printing levers and an iron core and reducing the movement difference between all of the printing levers by bringing a part of each of the printing levers into contact with a stopper part before the movable yoke part of each of the printing levers collides with the iron core. CONSTITUTION:When a printing signal is supplied to a drive coil 8, a part 4e of a printing lever 4 collides with a stopper part 15 immediately before a movable yoke part 4d collides with the rear of an iron core 7a and the printing lever 4 becomes impossible to further shake. The leading end part 4b of the printing lever 4 is advanced by the shaking of the printing lever 4 and the printing energy of an electromagnetic drive apparatus 6 is given to a printing element 1 and this printing element 1 advances to perform printing. After printing, since the attraction force from a core body 7 is not already exerted on the printing lever 4, the printing lever 4 receives the return force of a return spring 5 to retract but, since there is a slight gap between the movable yoke part 4d and the iron core 7a, the adsorption force between both of them is weak as compared with a close contact state and the printing lever 4 begins to move in order to immediately return and rapidly returns to the original stand-by state.

Title: Covered cemented carbide cutting tool
Inventor: UCHINO KATSUYA
IPC: C23C28/04
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To improve the abrasion resistance of a cover layer and prevent the occurrence of damage and peeling by forming an outer layer with κ-type aluminum oxide, and providing a region where grains having the α-type crystal structure and grains having the κ-type crystal structure are mixed directly above an inner layer. SOLUTION: Cemented carbide is used as a base material, an inner layer and an outer layer are provided on the surface, and the inner layer is formed with two layers or more of Ti(CwBxNyOz), where w+x+y+z=1 and w, x, y, z>=0. The mixing ratio of α-type aluminum oxide grains and κ-type aluminum grains directly above the inner layer is preferably set to κ/α=1 to 4 to obtain the κ-type aluminum oxide layer on the outer layer. When the κ/α ratio is kept in this range, high degree of adhesion and the formation of the final κ-type crystal structure aluminum oxide layer can be easily reconciled. The mixed state of κ/αexists not only in the first line, and the κ/α ratio is decreased toward the upper layer and becomes zero in the film.

IPC: G02F1/1335
Filed: 1988-08-01
Abstract: PURPOSE:To obtain the active diffraction grating which can be controlled electrically by making at least one surface of a transparent plate irregular in parallel stripes. CONSTITUTION:On a substrate 1, a transparent electrode 2 is provided and driven by a voltage source 4, but the surface of one of two substrates 1 or the transparent electrode 2 on the substrate 1 is made irregular in periodical stripes to generate a slight difference in panel thickness. An electric field E(x) applied to liquid crystal when a voltage V is applied between the electrodes of the panel because of the slight difference in panel thickness is represented as E(x)=V/d(x). Here, d(x) is the distance between the transparent electrodes and even if the same voltage V is applied according to the irregularity of the panel, the electric field E(x) applied to the liquid crystal is different. When a sufficiently high voltage is applied, the entire surface of the liquid crystal enters a nematic phase, but when the voltage drops, liquid crystal molecules go to parallel to the substrate selectively where the electric field is weak in recessed parts and spiral axes are arrayed in a specific direction to enable diffracted light to be converged on a specific position, so that the diffracted light and transmitted light can be switched with the voltage.
