Title: Drop preventing device for lifting type safety gate
Inventor: DOIMARU HAJIME
IPC: B30B13/00
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent a safety gate from being dropped immediately when a rope is cut by a method wherein an oscillating piece having a hanger pulley and oscillatable within a vertical plane including a rack is provided with a stopper tooth engageable with the rack and an energizing means for energizing the oscillating piece toward a direction to cause the stopper tooth to be engaged with the rack. SOLUTION: In the case that a safety gate 5 is hung, a tension force T is applied to a wire rope 14, an oscillating piece 11 is pulled inwardly against an energizing force of a coil spring 24 and oscillated in one direction, resulting in that a stopper tooth 18 is moved away from a rack 8 and so the safety gate 5 can be ascended or descended without any trouble at all.  During a time in which the safety gate 5 is being ascended or descended and the safety gate 5 is lifted up to its upper limit position, if a wire rope 14 is cut, a tension force T acted on the wire rope 14 is eliminated to cause the oscillating piece 11 to be released from the tension force T and at the same time it is oscillated toward the other direction by an energizing force of a coil spring 24 and the stopper tooth 18 is engaged with the rack 8, so that the safety gate 5 is supported at the rack 8 and prevented from being dropped.

Title: Input device for character or the like
Inventor: MAKINO HITOSHI
IPC: G06F3/023
Filed: 1987-02-10
Abstract: PURPOSE:To reduce the burden of an operator and to shorten input time by displaying characters on a second screen when characters are selected from characters or the like displayed on the first screen of a dichotomous display screen and performing the editing processing when an editing icon is selected. CONSTITUTION:An initial picture is displayed on a display part 6, and it is discriminated by a discriminating part 2 whether the input from a key input part 1 indicates a cursor movement or selecting key. In the case of the selecting key, a code table storage part 7 is referred to code the selected character by a code converting part 3. When this code is an editing icon key, an editing code processing part 4 performs a pertinent processing; but when it is not an editing icon code, the selected character corresponding to the code is displayed on a part of the display part 6. If said input indicates the cursor moving key, the cursor on the display part 6 is moved and a table itself of displayed characters or the like is scrolled by a display control part 5. Thus, all contents can be seen even if the capacity of the display part 6 is smaller than that of a character storage part 8.

IPC: H05B3/00
Filed: 1995-02-17
Abstract: PURPOSE: To provide a fixing device in which the temperature of the non-paper- passing area of a fixing roller is prevented from excessively rising and which does not have danger of causing such accident as a firing so as to have high safety in the case a small-sized recording paper having narrow width passes through. CONSTITUTION: A paper-passing-reference position 5 by which one side end of the recording paper P is aligned is set on one end of the fixing roller 35, and a thermistor 4 is arranged outside the position 5 on the roller 35. A halogen lamp (not shown in a figure) arranged inside the roller 35 has heating characteristic that heating value at the non-paper-passing area is smaller than that at the paper-passing area of the minimum size paper P including the position 5 by such a means of changing the number of turns of an inside heating element per unit length. As a result, the distribution of the surface temperature of the roller 35 in the case of non-fixing is kept nearly constant at the paper-passing area and is gradually lowered toward end from the vicinity of a boundary between the non-paper-passing are and the paper-passing area at the non-paper- passing area.

Title: Permanent magnet having excellent abrasion resistance and crack resistance, and manufacture thereof
Inventor: OKI TSUGUAKI
IPC: H04N7/00
Filed: 1988-02-09
Abstract: PURPOSE:To improve abrasion resistance and crack resistance, by coating a magnetic material that is formed by metallurgically combining powder for a permanent magnet with a nonmagnetic metal coating material having excellent abrasion resistance. CONSTITUTION:A magnetic material 1 is coated with a metal coating material 2. The magnetic material 1 and the metal coating material 2 are diffuse and bonded. The magnetic material 1 is a magnetic material wherein, e.g., powder for a rare earth magnet is metallurgically combined. The metal coating material 2 is a nonmagnetic metal material having excellent abrasion resistance such as, e.g., high Mn steel and austenite based stainless steel. Therefore, a magnet has the excellent abrasion resistance of the metal coating material 2, and the magnetic material is protected by the coating of the metal coating material 2. Thus, breaking and cracking are prevented. Since the magnetic material 1 and the metal coating material 2 form a unitary body as a material composition by the diffusion and bonding, bonding of both material is very rigid. Thus, the magnet having the excellent abrasion resistance and crack resistance can be obtained.
