Title: Magnetic recording medium
Inventor: NAOE MASAHIKO
IPC: G11B5/851
Filed: 1983-02-07
Abstract: PURPOSE:To obtain a magnetic recording medium which excels in both mechanical strength and chemical stability by forming the magnetic layer of the recording medium so as to satisfy the prescribed conditions. CONSTITUTION:The following conditions are satisfied with a magnetic layer 10 formed on a substrate 6 of a magnetic recording medium. That is, the layer 10 is equal to a continuous magnetic layer containing mainly iron oxide (a); the layer 10 has >=1.0 ratio of the remaining magnetization in the inner direction of the layer 10 to the remaining magnetization in the vertical direction (b); and the layer 10 has 100-5,000 Oe coercive force (c) respectively. The vertical magnetic fields are formed on the surfaces of targets T1 and T2 of a counter target sputtering device, and plasma of high density is formed between these targets. Then a target material is educed on the substrate 6. Thus the layer 10 of iron oxide is formed on the substrate 6 by means of a target material Fe (containing Co of 1-atom %) and an introduction gas Ar+O2 and under the conditions (a)- (c). Thus it is possible to obtain a magnetic recording medium which excels in both mechanical strength and chemical stability.

Abstract: PROBLEM TO BE SOLVED: To provide an acoustic device generating sound at a constant tempo, even if there is no electrical energy source such as a battery and a commercial power supply. SOLUTION: A music box 1 is provided with a generator 60 which converts kinetic energy from a spiral spring 11 to electrical energy and a rotation control means is driven by the electrical energy from the generator 60 for governing the rotation of a rotor 61 at a constant speed. Therefore, a rotating disk 52 driven operatively associated with the rotation of the rotor 61 can also be rotated at a constant speed. Thus, music can be played at a constant tempo without an electrical energy source such as a battery.

Title: Molding device for plastic ferrule for optical connector
Inventor: KAWAKITA MOTOYA
IPC: B29C45/36
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To enable prevention of defective products and omission of an inspection stage for products after molding by detecting broken core pins by a pin sensor at every shot before molding. SOLUTION: The rear surface of a V-groove formed portion B of a movable mold M2 is provided with a load cell holding part 39. This load cell holding part 39 is forward and backward movably provided with a load cell 40 as the pin sensor. A spring 50 wound to the outer peripheral part of a shaft 42 is disposed between the rear surface of the load cell 40 and the inside wall of the load cell holding part 39. The spring 50 absorbs the pressure that the detecting rod 41 of the load cell 40 receives when the load cell comes into contact with the core pin 10, thereby preventing excessive-pressure on the core pin. The position of the load cell 40 is detected by a position sensor 44. When the pressure is not detected even in a detection forward limit position forward of a detection reference position, judgment is made that there is a failure on the core pin.  The signal is then outputted to stop molding.

Inventor: MORI TAKESHI
IPC: H01G4/12
Filed: 1991-02-13
Abstract: PURPOSE:To provide a screen for screen printing capable of printing a film of uniform thickness over the entire of the screen. CONSTITUTION:The throughput amount of paste can be restricted proportionately to the thickness of a mask 1b on a screen by causing the mask 1b to become gradually thinner toward the center of the screen.
