Title: Gear and power transmission device having the gear
Inventor: KAWAI TORU
IPC: F16H55/14
Filed: 1993-06-16
Abstract: PURPOSE:To increase the contact ratio, and to reduce the noise and the vibration, by providing two teeth rows to a single gear, and composing the teeth of both teeth rows slipping a half pitch each other. CONSTITUTION:A pinion 3 is formed integrally by a plastic material, for example, it has two teeth rows 3a and 3b, and the teeth of both teeth rows have a slippage of 1/2 pitch each other. When the pinion 3 is rotated by a motor 1, the gear 4 is rotated by the first teeth row 3a, and at the same time, a gear 5 is rotated by the second teeth row 3b. Since the pitch of the teeth row of the gear 5 is combined slipped 1/2 pitch by a pin 5a to the pitch of the teeth row of the larger diameter gear 4a of the gear 4, the gear 4 is rotated smoothly regardless of the difference of pitch of two teeth rows. And since the gear contact ratio between the gears 4 and 5, and the motor pinion 3 is made higher than the gear contact ratio in a normal single teeth row, the teeth bearing sound is small, and thereby, a noise and a vibration can be reduced extensively.

Title: Apparatus for inspecting surface state
Inventor: SATO YOICHI
IPC: G06T7/00
Filed: 1990-06-01
Abstract: PURPOSE:To enhance inspection accuracy by further comparing an adaptation coefficient corresponding to the difference between the density histogram of an object to be inspected and theoretical frequency with a threshold value when the standard deviation based on the density histogram of the pixel of an object to be inspected is judged to be abnormal. CONSTITUTION:A television camera 10 takes the image of the surface of a foamed sheet and transmits a multilevel image sampled in a pixel unit to an inspection apparatus 20. A density histogram is calculated with respect to pixel data and the standard deviation sigma is compared with a preset threshold value alphadev to inspect the surface state of an object to be inspected. In the case of sigma>alphadev, the average value mu of the density histogram and the theoretical fre quency of each density according to regular distribution having standard devia tion sigma are calculated. The adaptation coefficient F corresponding to the differ ence between the density histogram and the density frequency is calculated and compared with a preset threshold value alphafit and the surface state is judged to be normal at the time of F <= alphafit and abnormal at the time of F > alphafit to output a result.

Title: Folding monitor system of optical signal
Inventor: TAKAHASHI MASAAKI
IPC: H04B10/077
Filed: 1981-09-14
Abstract: PURPOSE:To realize a folding test with high reliability, by cutting of the ascending signal of a repeater at the next stage in a repeating device to which the folding is designated. CONSTITUTION:A terminal station TS is connected to numbers of repeating devices RP0-RP2,... having the same constitution via the ascending and descending optical transmission lines LA0-LA2,... and LB0-LB2,.... When the TS transmits the signal indicating the folding of the RP1, a receiving part RSA1 of a descending repeating part RA1 of the RP1 is folded via an optical switch control part SWC1 to turn on an optical switch SWA1. Then the received signal is relayed to the RP2 via a gate GA1 and a light emitting part LDA1 and at the same time transmitted to an ascending repeating part RB1 via the SWA1. In the RP2, the RSA2 detects the folding of the RP1 and turns off a gate GB2 via a gate control part SCA2 to cut off the ascending transmission signal. Thus the TS can receive only the signal folded from the RP1.

When these counted values are made to be the representative point of the phase space of the two-dimensional linear differential equation, the coefficient matrix is inferred by the least square method, and the obtained coefficient matrix element is made to be the two-dimensional fractal feature quantity. Thus, since picture discrimination by two-dimensional fractal dimension is realized, a natural picture and a complicated picture in a wide range can be identified.

Title: Production of ceramic sheet
Inventor: KAWACHI JUNJI
IPC: C04B35/632
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To obtain an excellent ceramic sheet having homogeneous texture and uniform thickness by using a clay produced by adding methyl cellulose as a binder and a fatty acid ester as a plasticizer to powder of ceramic raw material. SOLUTION: Clay for the ceramic sheet is produced by adding methyl cellulose as a binder and a partially esterified glycerol fatty acid ester as a plasticizer to a powdery ceramic raw material and kneading the mixture. The ceramic sheet is produced by the extrusion molding of the clay. As an alternative method, a propylene glycol fatty acid ester is used as the plasticizer. The amount of the plasticizer is preferably about 0.2-5 pts.wt. based on the ceramic raw material. An excellent ceramic sheet can be produced since the slippery between the particles of the ceramic raw material powder in the clay is improved by the addition of the plasticizer to decrease the extrusion resistance difference in the lateral direction of the sheet in extrusion molding.
