Title: Lubricant for injection sleeve used in die casting
Inventor: SUWAPON KUMARU BOJIYU
IPC: C10N10/08
Filed: 1993-08-25
Abstract: PURPOSE:To reduce the amt. of reaction gas generated on supplying a molten metal into an injection sleeve while maintaining lubricity not inferior to that of a conventional lubricant by adding a small amt. of a fine silicone powder to a powder mixture comprising a thermal insulating powder as the major component and a lubricating powder as the minor component. CONSTITUTION:A thermal insulating powder prevents a molten metal supplied into an injection sleeve from getting into contact with the inner surface of the sleeve, examples being Al2O3, TiO2, SiO2, talc, and spinel. A lubricating powder improves the lubrication between the inner surface of the sleeve and the outer surface of a plunger chip and is used in an amt. of 16wt.% or lower of the total amt., and a self-lubricating powder such as stearic acid or a stearate can be used as the lubricating powder. A fine silicone power supplements the lubricity of the lubricating powder, pref. comprises spherical particles with particle sizes of 0.3-20mum, and is used in an amt. of 6wt.% or lower of the total amt.

Title: Cover body linking mechanism for electronic apparatus
Inventor: KUZUMOTO HIROYUKI
IPC: G06F1/16
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To hold the display section, i.e., the cover body, surely and stably at an arbitrary angle by arranging a frictional body, an urging means and a face pressure control member sequentially on a coupling shaft with the cover body supported rotatably on the body side. SOLUTION: When a cover body 15 is turned from a 90 deg. position toward a 180 deg. position where the cover body 15 intersects a computer body 12 substantially perpendicularly, a cam member 22 turns along with a linking shaft 19 and a cam member 21, being recovered by releasing a coned disc spring 23, presses a curved protrusion 21a gradually through a curved protrusion 22a. Consequently, the cam member 21 is separated by a maximum distance from the other cam member 22 and an annular frictional body 20c is compressed strongly. Frictional force between the annular frictional body 20c and an annular frictional body 20a increases the operating force required for turning the cover body 15.  It is balanced with the downward turning force caused by the self- weight of the cover body 15 and the actual operating force is kept at a substantially constant level at the time of opening/closing the cover body 15. Furthermore, the cover body 15 can be held surely and stably at that angular position.

Title: Control circuit of self-holding solenoid
Inventor: YANAGAWA MASASHI
IPC: H01F7/18
Filed: 1988-08-25
Abstract: PURPOSE:To obviate the need of providing a solenoid with a sensor for detecting position of a plunger by detecting counter electromotive force generated across a coil based on movement of the plunger when the coil is not excited, and exciting the coil based on a detection signal thus obtained for returning the plunger to the attracted position. CONSTITUTION:A self-holding solenoid 1 detects counter electromotive force generated in a coil 3, when a plunger 5 attracted to a yoke 2 is released from the attraction as the plunger 5 is held by the magnetic force of a permanent magnet 4. A first gate circuit outputs, based on the detected counter electromotive force, an output signal for attracting the plunger 5 to the yoke 2. Thereby, the plunger 5 is attracted again to the yoke 2 automatically. According to such arrangement, even if the self-holding solenoid 1 is subjected to any mechanical shock apt to remove the plunger 5, the plunger 5 can be kept in the attracted position stably. Further, since removal of the plunger 5 can be detected based on counter electromotive force generated in the coil 2, there is no need of providing the solenoid 1 with a sensor for detecting position of the plunger 5.

Title: Paddy working machine
Inventor: OKUDA HIROSHI
IPC: A01C11/02
Filed: 1992-08-10
Abstract: PURPOSE:To prevent erroneous measurement of the mud hardness due to a detection failure of a mud hardness sensor and to prevent an elevation control failure by elevatably supporting the sensor to the machine body side, not to the working unit side. CONSTITUTION:The position of a seedling planting unit 3 is controlled to a preset height from the paddy surface (G) based on a detected value by a height sensor 16. If the mud on the paddy surface (G) is hard, a mud hardness sensor 1 is shaken by a mud pressure from a prescribed position upward on the basis of an arm 2. In this case, the sensitivity of elevation control is changed to the insensitive side. On the contrary, if the mud on the paddy surface (G) is soft, the sensitivity is changed to the sensitive side. In case the mud hardness sensor 1 is moved not downward, but unexpectedly upward following an upward movement of the seedling planting unit 3 from the preset height, it judges that a waste straw, etc., is attached to the sensor 1. The sensitivity of elevation controller is, therefore, not changed and the second actuator 11 is operated to the elevation side so as to elevate the sensor 1 and to remove the waste straw. On the contrary, in case the sensor 1 is moved downward following a downward motion of the seedling planting unit 3, the second actuator 11 is operated to the descent side so as to move the sensor l along the bottom of a locally recessed part.
