Title: Length meter for stranded conductor
Inventor: TANAKA MASASHI
IPC: B21F7/00
Filed: 1988-12-23
Abstract: PURPOSE:To reduce length measurement error without enhancing measurement accuracy of a length meter and to make it possible to measure the length even in a narrow place where a length measurement wheel cannot be installed from underside of a cable by suspending the length measurement wheel from a projecting end of a frame above a capstan via a spring. CONSTITUTION:A length meter 5 for obtaining a specified length of a stranded cable 2 is formed with an L-shaped frame with its upper portion projecting. A length measurement wheel 57 is suspended from the projecting end 52 of the frame 51 via springs 54, 55 above a capstan 3, and is brought into contact with a conductor 2 wound on the rotating capstan 3 to roll on the conductor 2. The effect of the springs prevents the length measurement wheel 57 from bouncing excessively even if there is fructuation in the waviness of the stranded wire 2 and prevents the stranded wire surface from being bruised. This reduces the length measurement error without enhancing the accuracy of the length measurement and makes it possible to measure the cable length even in a narrow place where the length measurement wheel 57 cannot be installed from underside of the cable.

Title: Cleaning device for liquid surface
Inventor: OGURA SHIRO
IPC: E02B15/00
Filed: 1990-11-29
Abstract: PURPOSE:To automatically clean the surface of liquid by a method in which a hollow container is set to be immersed in a stored liquid, a filter to arrest dust in the liquid is set in the container, and a pump to discharge the liquid to the outside of the container is also provided. CONSTITUTION:A liquid 2 stored in a pool is directed through the weir side 3b of a hollow container 3 into the water region 6 of the container 3. In this case, dust floating on near the surface of the stored liquid is arrested into the region 6, and the coming liquid is filtered through the filter 9 to remove dust in the liquid. The liquid so clarified is directed into a drain region 7 and discharged to the outside of the container 3 by a drain pump 11, where the liquid is forcibly circulated repeatedly between the bottom of the surface of the liquid 2 for cleaning the whole of the liquid 2. The cleaning operation can thus be automatically made without resorting to hand.

Title: Dehydrating method of bound water in pisolite ore
Inventor: OKAZAKI JUN
IPC: C22B1/00
Filed: 1993-12-01
Abstract: PURPOSE:To dehydrate the water of crystallization in pisolite ore without requiring a high-temp. heat source and without generating thermal crack of the goethite part in the ore by irradiating the pisolite ore with electromagnetic waves and heating the pisolite ore to a specific temp. CONSTITUTION:The pisolite ore adjusted to a grain size of about <=10mm is supplied from an ore hopper 1 onto a conveyor 2 and the thickness thereof is adjusted by a cut off plate 3 to about <=100mm thickness. While this pisolite ore is continuously moved, the ore is irradiated with the electromagnetic waves of a frequency of about 2450MHz frequency from an electromagnetic wave generator 4 with an output of about 300W or over to 30kw/t-ore. Irradiation distances P1 to P2 are preferably about 50 to 100cm and the irradiation time about over 5 to 60 minutes. The pisolite ore is heated to 300 to 500 deg.C by such irradiation. As a result, the water of crystallization in the pisolite ore is removed without powdering the ore itself and the sintered ore having high strength is produced at a high yield.

Title: Quickly charging method
Inventor: ISHIMARU MASATOSHI
IPC: H02J7/04
Filed: 1987-12-23
Abstract: PURPOSE:To preferably quickly charge a battery by repeatedly charging and discharging the cooled battery, then shifting it to a large current-charging, switching to a small current charging if the voltage starts abruptly rising, pausing the charging at the peak voltage point, and setting an additional charging time by a timer. CONSTITUTION:When a start switch is closed, the temperature of a battery is detected by a temperature sensor. When it is lower than an ambient temperature, a temperature rising circuit is operated, discharging by a discharging circuit and charging by a constant-current circuit are repeated to raise the temperature to the ambient temperature. When the sensor detects that the temperature becomes the ambient temperature, it is charged by a large current set by a constant-current setter. If the temperature starts quickly rising to become a predetermined voltage, it is charged by the normal charging current set by the constant-current setter. When the voltage arrives at a peak, a delta peak detector detects it, and when the battery temperature is higher than the ambient temperature, the charging is temporarily stopped. Then, when the temperature falls, the time of the additional charging is set by a timer, and the charging is conducted. In this manner, it can prevent it from overcharging and quickly charge it.

Title: Method and device for processing optical information medium
Inventor: OBINATA KOKICHI
IPC: G11B11/10
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To allow an efficient processing for making information unreproducible in optical information media such as CD information under a clean working environment by applying microwaves to the above media and, by inflicting mechanical damages on the conductive film which forms the reflection film of an optical information medium by the high-frequency electric field of microwaves. SOLUTION: When a CD1 is irradiated with microwaves 2, its reflection film 12 is mechanically destroyed and cleavages 15 spread on the whole reflection film 12. In this case, this CD1 is particularly made unsusceptible to tracking servo of the reproducing device, inactivating the reproduction of information. For this purpose, it is desirable to set the irradiation period of microwaves 2 in the range of 1-10 seconds for one piece of CD. Too long irradiation of microwaves 2 beyond 10 seconds inductively heats insulators such as transparent substrate 11. Especially the packaging film of a plastic case might be molten.
