Abstract: PURPOSE:To improve the resistance to scuffing, wear, etc. of a sliding member and to make the member usable at a high temp. by subjecting a powder mixture composed of Fe-Ni alloy powder and Ni self-fluxing alloy powder to plasma melt spraying on the surface of the base material. CONSTITUTION:The Fe-Ni alloy powder to be used contains, by weight %, 35- 55% Ni, 0-8% Cr, 4-10% Si, 0-2% C, 0-3% B, and consists of the balance substantially Fe. The Ni self-fluxing alloy powder consists, likewise by weight %, of 8-20% Cr, 1-4% B, 1-6% Si, 0.3-2% C, 2-6% Fe, 0-1% Co and consists of the balance substantially Ni. This sliding member is formed by forming a melt sprayed layer on the surface of the base material by plasma melt spraying of a powder mixture composed of 20-60wt% the above-described Fe-Ni alloy powder and 80-40wt% the Ni self-fluxing alloy powder.

Title: Discharge control circuit
Inventor: MATSUMOTO KATSUHIRO
IPC: G05F1/02
Filed: 1988-02-16
Abstract: PURPOSE:To accomplish high-speed and stable electric discharge machining by providing a reference voltage for detecting shortage of discharge, whereby after the start of discharge is detected, shortage of discharge is detected to stop and initialize pulse on-off cycle not contributed to machining. CONSTITUTION:Positive output voltage VP of a power supply PS for machining is applied to a machining gap between a machining electrode H and a work W through a transistor TR operated according to an on-off signal VG to perform discharge machining. When a discharge start signal OUT1 is output from a comparator OP1, FF1 is set by a differentiating circuit DF1, and when count values in counters CT1, CT2 reach pulse-on or pulse-off time data Sh, Sg, a pulse on-off source signal OUT3 is output. At this time, if shortage occurs, a machining gap signal V0 becomes larger than a reference voltage VB for detecting shortage of discharge, so that a shortage of discharge detection signal OUT2 is output from a comparator OP2 and FF1 is reset by a differentiating circuit DF2. Thus, useless pulse on-off cycle is stopped and initialized.

Filed: 1993-02-22
Abstract: PURPOSE: To automatically discriminate whether an inputted medium is positive or negative slide by defining a dark level and a light level with respect to a picture histogram so as to compare with a previously fixed threshold value. CONSTITUTION: The digital image of the inputted medium being negative or positive slide is received as an input. This digital image is the description of the inputted medium resolved to its color resolving components in the color coordinate system of RGB.

Next, an area of vary high contrast such as one typically generated at an edge part between a perforation and a film boundary and an area of very low contrast such as one typically generated within the perforation and the film boundary are removed. Concerning a histogram generated after removing, quantitative reference is used to discriminate negative or positive.

Title: Anamorphic f lens system
Inventor: KAWAMURA ATSUSHI
IPC: G02B27/00
Filed: 1978-03-23
Abstract: PURPOSE:To make it possible to reduce the pitch irregularity without any use of cylindrical or troidal lens at the side being scanned by using an anamorphic ftheta lens which has unique optical characteristics in two directions perpendicular to an optical axis. CONSTITUTION:An ftheta lens system 1 is arranged such that its iris PE is aligned with the reflecting surface of a rotary polygonal mirror 3. If this mirror 3 is turned in the direction of arrow, the line scanning operation is accomplished at a uniform speed with the spot of the reflected flux of light. In the direction z, since the image of the unidirectional light flux incident upon the reflecting surface is focused upon an image plane 2, no fluctuation takes place in the direction z on the image plane 2 even if the sweeping plane of the reflected light flux is vluctuated due to the fluctuations in the parallelism of the mirror surface of the mirror 3 with respect to the axis z. Thus, the irregularity in the pitch of the line scanning operation can be reduced. Thus, the irregularity in the pitch of the ftheta lens can be reduced merely by adjusting the position in high accuracy with respect to the reflecting surface of the mirror and to the scanning plane.
