Title: Sliding member
Inventor: ODA ISAO
IPC: F02F5/00
Filed: 1987-06-24
Abstract: PURPOSE:To obtain excellent wear resistance at a room temp. and, particularly, at a high temp. by transferringly sticking a metal on the sliding face of a metallic member to a ceramic member and forming a metal coated lubricating layer on the sliding face of said ceramic member. CONSTITUTION:A metallic member which slides against a ceramic member made of silicon nitride, sialon, a partially stabilized zirconia, or silicon carbide is formed with a metal containing 32 wt% or more of Mo, or 20 wt% or more of Co, or 84 wt% or more of Ti, or 5 wt% or more of W. When these two are used in combination for engine members, a tappet or a rocker arm and a cam, a valve and a valve seat, and a liner and a piston ring, a metal coated lubricating layer is formed on the sliding face of the ceramic member. Hence, excellent wear resistance at a room temperature and, particularly, at a high temperature can be given to these parts.

Title: Lead frame
Inventor: ARAI SHIGERU
IPC: H01L23/48
Filed: 1987-06-24
Abstract: PURPOSE:To improve productivity and solderability in a lead frame supported in cooperation of leads with an outer frame by so forming burrs formed by pressing at a lead group region as to be directed toward opposite side to a land contact face of the lead. CONSTITUTION:When a multi-lead frame 1 is so arranged that the main face of a film 10 is directed upward, burrs 11 of outer frames 3, 3 are directed upward, and burrs 11 of a lead group region A are directed downward. Since a recess 15 is so submerged at the center of a feeder 14, i.e., at a region opposite to the region A as to escape the burrs 11 protruded downward, the frame 1 is slidably contacted with the surface of the feeder 14 at the frames 3, 3 at both ends. Since the burrs 11 of the frame 3 are directed upward, the burrs 11 are not engaged with the surface of the feeder 14. Accordingly, an accident of improperly bending the leads or stopping a conveyance of a feeder can be avoided in advance.

IPC: B66B13/08
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To produce a structure which is not locally subject to bending to protect a cable, improve workability of the work for fixing the cable of a car door, and make the cable invisible from passenger side through door with a window to improve a design property. SOLUTION: When a car door is moved from a door-closed end position up to a door-open end position in the right drawing, a hanger 2 fixing side of a guide chain 13 is moved to the left. Since the guide chain 13 is regularly bent-deformed, constantly accompanied by a uniformly curved shape, at that time, a cable 12 is not locally subjected to repeated bending, torsion, and extension and contraction in a narrow space at the upper part of the door, and the cable can be moved with the opening and closing of the car door 1, with the length of the cable being minimized.

Title: Echo canceler type 2-wire/4-wire canceler
Inventor: YASUDA SUSUMU
IPC: H04B3/23
Filed: 1987-06-22
Abstract: PURPOSE:To judge a trouble of an echo canceler or the disconnection of a line in a communication unable state by detecting only a pseudo echo in a look-back mode to confirm the normal working of an echo canceler. CONSTITUTION:In a loop-back mode a switch 3 is set at a ground level with a switch 7 connected to a bit inverting circuit 6 and an estimated coefficient is fixed by means of a switch 13. Under such conditions, a pseudo echo signal produced by an echo canceler is supplied to a subtraction circuit 4 and an inverted pseudo echo signal is supplied to a wave detecting circuit 5. The pseudo echo signal undergone the wave detection and binary coding through the circuit 5 is supplied to an interface part 8 after the bit inverted by the circuit 6. The part 8 compares the transmission signal with the received pseudo signal. Then the normal working of the echo canceler is decided when the coincidence is obtained between said both signals. Thus the loop-back mode is through and a normal working state is reset.

Abstract: PURPOSE:To unnecessitate the setting of a user program, to unnecessitate the calculation load of a spline curve with a CPU, to guide the moving body to an arrival target point TP without specifying a path to the arrival target point, and to coincide the traveling direction of the moving body with the preset direction at the target point. CONSTITUTION:A moving body 1 in which a driving speeds of both driving wheels LW and RW are controlled independently of each other according to an arithmetic formula including parameters based on the positional relation with the arrival target point TP is guided toward the TP without specifying a route. Thus, the gain of an azimuth deviation being a parameter between the present traveling direction of the body 1 and the traveling direction at the TP included in the arithmetic formula is changed according to the distance between the body 1 and the arrival target point TP. Further, two types of parameter gains are provided to determine respective gains of the parameters so as to prevent the traveling route of the moving body from curing when shifting between the gains.
