Title: Filling apparatus
Inventor: SUGIYAMA NOBORU
IPC: B67C3/20
Filed: 1989-04-12
Abstract: PURPOSE:To permit a rapid and precise control of the liquid level of the contents of a container by effecting such a control as to make the liquid surface height of the filled contents constant independently of the container volume. CONSTITUTION:The containers 2 to be filled with the contents 1 are placed and weighed successively on a container weighting part 3. The weight data outputted from this weighing part 3 is compared at a computing part 5 with the weight data stored in a memory part 4 for storing a correlation between the weight and volume of a container, whereby the volume of the container commensurate with the weight is computed. On the other hand, the contents 1 are supplied from a filling part 6 and the starting and stopping of the filling and the filling speed are regulated by a control part 7. This control part 7 controls the filling part 6 based on the volume data from computing part 5, i.e. the filling part 6 is regulated so as to increase the filling amount when the container volume is large and decrease the filling amount when the container volume is small. This method can increase the reliability by consumers of the content volume of an article.

Title: Manufacture for magnetic head for flexible magnetic disk
Inventor: SHINDO NORIO
IPC: G11B5/127
Filed: 1987-04-15
Abstract: PURPOSE:To grind a magnetic head into a shape for obtaining an optimum abutment with respect to a magnetic disk by correspondingly arranging the magnetic head and a pad member with a flexible lapping disk sandwiched and abutting the pad member on the lapping disk. CONSTITUTION:A jig supports the magnetic head 1, which is permitted to deal with one side of the flexible lapping disk 4 which is fitted to a spindle 3 in a way that is rotates similarly with the magnetic disk and the pad member 7 is arranged on the opposite side of the magnetic disk 1 with the lapping disk 4 sandwiched.

Title: Superconducting transformer
Inventor: KISHIGAMI TOMOHISA
IPC: H01F6/06
Filed: 1990-04-06
Abstract: PURPOSE:To perform a transformer function without hysteresis from a primary winding to a secondary winding by performing transfer of a magnetic flux by means of a magnetic shield function of a superconductive material in a closed loop transmission path in a main body. CONSTITUTION:When high frequency current is supplied to a primary winding 2, no electromagnetic wave does not leak outside a transmission path 1a as a main body 1 is composed of a superconducting material. Since a slit 1b is formed on the transmission path 1a, current interfering with a change in its magnetic flux is not generated in the superconducting material so that the change in the magnetic flux can be securely transmitted. The change in the magnetic flux causes high frequency current to flow to a secondary winding to perform a transformer function. Since there is no magnetic body in a magnetic circuit at this time, the path can function as a transformer without hysteresis as well as it is not be magnetically saturated even if large current is made flow. In addition since no magnetic flux does not leak outside the transmission path 1a, radiation noise can be reduced by means of a magnetic shield effect.

Title: Zoom lens
Inventor: YONEZAWA YASUO
IPC: G02B15/16
Filed: 1991-04-01
Abstract: PURPOSE:To reduce the variation of an exit pupil by setting an entrance pupil on an object side by moving a 4th lens group among a positive, a negative, a positive, and a positive lens group to an image side and increasing the interval between the 1st and 2nd lens groups at the time of power magnification from a wide-angle end to a telephoto end. CONSTITUTION:When the zoom lens consisting of the lens groups G1-G4 which have the positive, negative, positive, and positive refractive indexes in order from the object side is varied in power from the wide-angle end to the telephoto end, a 4th lens group G4 is moved to the image side and the interval between the 1st and 2nd lens groups G1 and G2 on the axis is increased. Then, 0<(d12T- d12W)/(BfW-BfT)<=1 and BfW>BfT is satisfied where d12T and d12W, and BfT and BfW are the on-axis lens intervals and back focuses of the 1st and 2nd lens groups at the telephoto end and wide-angle end. Consequently, the zoom lens which has the entrance pupil on the object side about the 1st surface and extremely small variation of the exit pupil due to zooming is realized.

Title: Hard laser marked wafer and manufacture thereof
Inventor: MATAKAWA SATOSHI
IPC: B23K26/00
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent the surface of a wafer from being damaged during abrasion by eliminating reduction in flatness of the wafer which is attributable to hard laser marking. SOLUTION: An etched wafer is subjected to hard laser marking. An annular projecting part (a) is formed around the edge of a hard laser mark forming part. The marked surface of the wafer is ground, using a #1500-#3000 resinoid bond grindstone manufactured by Disco Kabushiki Kaisha. The part (a) is shaved. Then, the ground surface of the wafer is polished to mirror surface finish. The surface of the wafer, which has been flattened with the part a removed by grinding, is polished. As a result, the problem of the planarity of the wafer being reduced due to hard laser marking can be eliminated. This also prevents the surface of the wafer from being damaged, due to debris of the part which fell from the hard laser mark forming part during polishing.

Title: Tester of blower
Inventor: ATSUNO YOSHIKI
IPC: F04B51/00
Filed: 1984-05-11
Abstract: PURPOSE:To determine the dynamic characteristics of a blower by applying abrupt pressure changes in an environment where the blower is operated and measuring and recording the activities of the blower at that time with a pressure sensor and a wind speed sensor. CONSTITUTION:Normally, a blower 2 is operated so that the wind flows in the arrow direction into a pressure change room 1 from the outside. On the other hand, the high-pressure air is stored in a chamber 4 from a compressor 3 via a valve 5. Under this condition, when an instantaneous release valve 6 is operated, the high-pressure air in the chamber 4 abruptly flows into the pressure change room 1, thereby the pressure P2 in the pressure change room 1 is quickly changed. The operation points of the blower at this time are detected by a pressure sensor 7 and a wind speed sensor 8 and are simultaneously recorded by a recorder 10. Thereby, the dynamic characteristics of the blower 2, when the pressure of an environment where the blower 2 is operated is abruptly changed, can be determined. In addition, the dynamic characteristics in response to individual conditions can be determined by changing the initial pressure in the chamber 4 and changing the pressure changing states in the pressure change room 1.

Title: Magnetic recording/reproducing method
Inventor: IDE AKIFUMI
IPC: G11B5/008
Filed: 1990-04-09
Abstract: PURPOSE:To cope with a different signal form and to cope with different magnetic tape width and different track length by providing one pirce or more of gap parts on both ends of a track formed on the magnetic tape and on other part than both these ends. CONSTITUTION:A data train 18 shows a length equivalent to just one track length of an output data train of a format device 5, and is provided with gaps 19, 18C and 20. Also, since one track is formed by a just half of the data train 18, it is divided into two in the part of the gap 18C and becomes two pieces of tracks. As a result, even if track length decreases, a gap is formed in both ends of the track, therefore, a recordable/reproduceable format is obtained. That is, in order to correspond to a relative speed of N folds and track length of 1/N, the gap is placed so as to divide the track length into N in general. In such a way, even in the case of a different relative speed, different magnetic tape width and different track width, information can be recorded and reproduced effectively.

Title: Overcurrent protective method for power unit and overcurrent protective circuit
Inventor: SUZUKI KAZUYA
IPC: H02M3/28
Filed: 1990-04-09
Abstract: PURPOSE:To suppress the increase of output currents by narrowing the on pulse width of a switching element at the time of overcurrent occurrence and also lowering the reference voltage for overcurrents in a DC-DC converter, or the like. CONSTITUTION:The overcurrent detecting circuit 15 of a control circuit 14 is composed of an operating circuit 15B, etc., and compares the output of a current peak detecting circuit 16 with the reference voltage for overcurrents. If the current of a switching element increases by the occurrence of an output short accident, or the like, a control circuit 14 narrows the on pulse width of the switching element 4. The capacitor 15F, which is charged in on period, discharges electricity during the period when there is no on pulse, so the charge voltage of the capacitor 15F falls. Accompanying this, the voltage of the reference input terminal of an operating circuit 15B falls, and the difference between the detection signal and the reference voltage for overcurrents enlarges. This way, the increase of output currents resulting from the delay of the control circuit 14, etc., is suppressed.
