Title: Solid lubricant
Inventor: HONDA FUMIHIRO
IPC: C10N40/04
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain a solid lubricant having a reactivity at a friction interface, capable of manifesting excellent lubrication activities at a high temperature for a long time, capable of preventing generation of seizing, and useful at a sliding part or the like exposed to a combustion gas by including a carbon powder and a specific metal powder. SOLUTION: This solid lubricant comprises (A) a carbon powder (e.g. a carbon black, a graphite) and (B) a group VIa, VIIa or VIIIa metal powder in the periodic table. Preferably, the lubricant contains 0.05-5 wt.% component B, and especially in the case of using nickel as the component B, contains 0.05-2 wt.% component B. When the lubricant is used at a sliding part, the component A is graphitized by a frictional heat, a tribochemical reaction and a catalytic action, and even when the component A is the graphite, the reorganization of the graphite layer is caused to prevent heightening of the friction coefficient caused in the time of sliding only with the simple graphite. As a result, excellent lubrication activities are manifested for a long period even at a high temperature.

Title: Extraction method for primary object
Inventor: KANESHIRO NAOTO
IPC: G06T7/00
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To improve the production efficiency of a print by extracting a primary object using the extraction parameter of an image whose the primary object is already extracted. SOLUTION: At a set-up part, the state of a primary part is classified into plural types and several methods from object extraction methods are selected according to the respective states of the primary part. Thus, a suitable primary extraction algorithm is set. In normal primary extraction, many objects are extracted corresponding to the top-bottom directions in all directions in order to extract a face in response to various images. Thus, the face is extracted by using the result. If the states of the primary part e.g., the top-bottom direction and the size, etc., are known, it is not required to extract the many objects in response to the various image states and if the objects are extracted in response to the states of the primary part, sufficiently high accuracy extraction is performed. Accordingly, the arithmetic time, etc., can be significantly shortened for an image having its preceding similar image and the high accuracy extraction can satisfactorily be performed.

Title: Ferroelectric liquid crystal electrooptic device
Inventor: SHIMODA SADAYUKI
IPC: G09G3/18
Filed: 1986-03-17
Abstract: PURPOSE:To set inverted pulse width to a proper value all the time and to stably drive liquid crystal over a wide operating temperature range by adjusting a reference clock within a specific range for the compensation of the switching temperature dependency of a ferroelectric liquid crystal cell. CONSTITUTION:Temperature compensation is so performed that the inverted pulse width tau is set in an area determined by an upper-limit line and a lower- limit line; and the oscillator of a variable frequency oscillator 11 is a multivibrator composed of two inverters, one capacitor C, and one thermistor R17 and its oscillation frequency (f) is 1/2.2CR. When the thermistor 17 has negative temperature characteristics, (f) becomes smaller and smaller as the temperature is lower and lower. When (f) decreases, the frequency of CL2 also decreases and inverted pulses which are in inverse proportion to it increase in tau. The thermistor varies in R according to an exponential function, so (f), therefore, taualso varies according to an exponential function. The temperature dependency of a switching speed varies according to an exponential function, so the temperature compensation which uses the thermmistor sets tau within a preferable area.
