Title: Production of powdery zirconium dioxide
Inventor: STERZEL HANS-JOSEF DR
IPC: C01G25/02
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To obtain chloride-free zirconium dioxide powder without passing through a complex mechanical treating process by producing powdery zirconium dioxide from a soln. prepd. by dissolving a chloride-free zirconium compd. in a formic acidwater mixture.

The molar ratio between the formic acid and water is usually l:1 to 1:3 and the dissolution temp. is 50-90 deg.C. Evaporable components are removed from the resultant soln. advantageously by spray-drying the soln. and the remaining solid is fired to form zirconium dioxide. An additive stabilizing the tetragonal transformation of ZrO2 . as an end product to change to monoclinic transformation or a precursor of the additive may be added at any time.

Abstract: PURPOSE:To obtain a uniform and stable optical output, by controlling the current-controlling element of a first constant-current circuit through a second constant-current circuit in an electrophotographic printer and the like and by maintaining a light emitting diode-driving current at a specified value. CONSTITUTION:In the second constant-current circuit of an integrated circuit 11, by a specified constant-current value Ic through a resistor 5c and a reference voltage Vrf, a voltage comparator 6b applies a gate voltage VG1 to MOS transistors 4c and further 4b, electric current Ii flowing through a loading resistor 5b is identical with Ic, and the point B reference voltage Vr2 of the voltage comparator 6a of said first constant-current circuit is VDD-RIN(VDD-Vr1)/RE. Therefore, the MOS transistor 4a of the first constant-current circuit setting Vr2 as a reference voltage sets electric current Iz flowing through a resistor 5a as Iz=Io, and the driving current Iz of LED3 is determined by a high accuracy resistor 5c. Thus, it is possible to obtain a uniform and stable optical output.

Title: Film carrier and manufacture thereof
Inventor: OTA TADAKATSU
IPC: H01L21/60
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To produce a film carrier having high through-hole reliability by providing conductive parts formed by burying conductive wires in through-holes. SOLUTION: Wires 4 are bonded to through-holes 3 of 50μm diameter formed by an excimer laser through a polyimide film 1 75μm thick. After feeding the wire 4, without cutting it, it is bonded again to each hole 3 and cut to form a conductive part 3a. Cu is vapor-deposited to form a Cu layer 2 (upper surface 1). After cutting the wire and fed, the second bonding may be applied to the upper surface Cu layer, without twice bonding at the same hole. Thereafter the wire is cut. Thus it is possible to obtain a film carrier having a high through-hole reliability at low cost in a simple process.

Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To automatically open a door in case of an earthquake and, at the same time, to prevent the door from being opened when no one is in the house by providing a door lock releasing mechanism acting in correspondence with an earthquake sensor together with a door chain releasing mechanism, and adding a door opening prevention mechanism when no one is in the house. SOLUTION: When an earthquake sensor 1 detects an earthquake exceeding a certain level, a door lock releasing mechanism 2 and a door chain releasing mechanism 3 are operated by an output signal 1a of the sensor, and a door opening mechanism 4 is operated by an operating complete signal 2a of the door lock releasing mechanism 2 to open a door. Those operating mechanisms use form restoring force by heating of a form memory alloy spring or a direct acting actuator. As a door opening prevention mechanism no one is in the house, an inverted switch is operated when a door chain is locked and unlocked by sliding it up and down, and the earthquake sensor 1 is thereby turned ON/ OFF. Accordingly, the door is surely opened in case the earthquake occurs, an evacuation route is ensured and, at the same time, the opening of the door is prevented to secure safety when no one is in the house.

Abstract: PURPOSE:To convert usual power force into powerful one through a servo unit, transmitting this power to a crankshaft, by installing two crankpins in each central crankshaft, attaching a gear to one end, connecting two horizontal rods to these crankpins in a doglegged form each, pivoting each of the sliding ends to the crankpins, and pivoting the other ends to each stationary plate. CONSTITUTION:Each rotation of both crankpins 2, 3 of a central crankshaft 1 is very slow at both ends by operation of two horizontal rods 6, 7, but it becomes speedier in proportion as moving the center, and there is an angle difference in 90 degrees between then, through which they are pivotally attached to each of stationary plates 19, 20. Each of bearing holes 30, 31, 32, 33 of the horizontal rods is formed into a short groove hole so that these crankpins 2, 3 rotate smoothly. In this connection, crankpins 4, 5 of another central crankshaft 27 operate in the same movement as those of the central crankshaft 1. When a gear 28 being attached to the shaft 1 rotates at high speed, a gear 29 being attached to the crankshaft 27 rotates at low speed, so that it races together with a catch 37 transmissible to one direction alone. When the gear 28 is in slow rotation, it races together with a catch 36 transmissible one direction alone as one body with a gear 34, rotating a shaft 38 mutually, and a hoisting disk 39 attached is rotated, winding a rope 40, thus a load 41 is lifted up.

Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To reduce a man-hour for adjusting a mark sensor in a mark detecting device during production and when the kind of recording paper is changed and secure stable mark detection during operation. SOLUTION: A main control part 1 changes the supply voltage to a light source 21b by means of a voltage control circuit 23 and, using changes in the light source output, changes the light reflected from or transmitted through recording paper 5, so that the voltage received by a photosensor 21a changes. A comparator 22a compares an input voltage from the photosensor 21a with a reference voltage Vr to determine whether or not a mark exists. The mark detecting operation is repeated as the light source output is changed, and an optimum light source output is calculated from the number of mark detecting steps sampled, to adjust the light source output. Also, the light source output is changed into the optimum one by means of the number of mark detecting steps which result from mark detection during operation.
