Title: Lifting device
Inventor: TAKAHASHI KAZUYOSHI
IPC: A61G5/00
Filed: 1989-07-26
Abstract: PURPOSE:To constitute the device so that it can ascend and descend in a state that a horizontal state remains maintained by operating one main X link leg connected to the upper base, and also, operating a sub-X link leg by synchronizing therewith, and moreover, operating the other main X link leg by synchronizing with the operation of the sub-X link leg. CONSTITUTION:In a formed sink base, the upper base A1 being its upper part ascends and descends against the lower base A2 being its lower part by an expansion driving source 10 in a lifting mechanism 1. For instance, when the expansion driving source 10 is expanded, each upper end of main X link legs 20, 30, especially, each upper end positioned in the front side of the lower base A2 ascends so as to follow an expansion of the expansion driving source 10, allows the upper base A1 to ascend in a state that it remains maintained horizontally, and prevents that the upper base A1 ascends in a forward inclined state. When the expansion driving source 10 is expanded, sub-X link legs 40, 50 also operate synchronously under the interposition of a connecting rod 60. As a result, by an operation of a pair of left and right sub-X link legs 40, 50, the upper base A1 is not inclined in the horizontal direction but allowed to ascend, and since the main X link legs 20, 30 are also operated synchronously, the upper base A1 is allowed to ascend in a state that it remains maintained horizontally.

Filed: 1990-07-23
Abstract: PURPOSE:To enable fast access by comparing a value which is shifted by a constant level through a level shifting circuit from a dummy word line potential with a bit line precharging potential and detecting it, and starting bit-line sensing operation. CONSTITUTION:The device is equipped with a row decoder 16 which selects rows of a memory cell array 17, the level shifting circuit 13 provided at the output terminal of a dummy word line potential generating circuit 11, and a threshold circuit 14 which outputs a word line rise detection signal. The output potential of a dummy word line potential generating circuit 11 is passed through the constant level shifting circuit 13 and compared with the bit line precharging potential and when the precharging potential is exceeded, the word line rise detection signal WUP is outputted and used to start the bit-line sensing operation. Therefore, the delay time from the rising of the word line potential to the start of the bit-line sensing operation is a necessary irreducible value determined by the level shifting circuit 13. Consequently, the fast access becomes possible.

Title: Magnetic head
Inventor: IHARA KEITA
IPC: G11B5/127
Filed: 1986-08-19
Abstract: PURPOSE:To obtain a magnetic head advantageous for a narrow gap, and suitable for mass production, by filling a step between a metal magnetic material and other layers generated on the gap plane of a core having compound structure, with a nonmagnetic metal oxide in which the metal magnetic material is oxidized. CONSTITUTION:A thin metallic film magnetic material 8 is formed on a substrate 9 such as a glass group, etc., in which the magnetic material 8 and the substrate 9 are laminated alternately. By segmenting the blocks of a head core A5, and a head core B6 from the above laminated material, and grinding the gap plane 2 of the magnetic head, the step due to inclined abrasion is generated between the magnetic material 8 and the substrate 6. After the generation of the inclined abrasion, the film of metallic oxide is formed at the metal magnetic material 8 on the gap plane 2 by applying a heat processing. Since the volume of the metallic oxide increases larger than an original metal, the step between the magnetic material 8 and the substrate 9 is recovered. Afterwards, the gap 1 is stuck by a back gap 7, and is joined by pouring a bonding glass 3, thereby, the mechanical strength of the gap is obtained, and the magnetic head can be obtained by segmenting a head chip in the vertical direction of the gap plane 2.

IPC: G03G13/01
Filed: 1984-09-17
Abstract: PURPOSE:To improve gradation capacity from a low image density part to a high image density part by forming preliminarily a relatively rather underexposure electrostatic latent image and correcting this electrostatic latent image in accordance with the image density by digital erasing. CONSTITUTION:For the purpose of obtaining an ideal electrostatic latent image, an ideal exposure is determined for each image density, and the output of a color solid-state image pickup element in case of read of an original is checked when this determined exposure is set, and relations of a curve 4-1 are stored in a microcomputer. Since the original is read before the copy process, relations between the density of the color picture part of each color separation picture and the signal output and relations between the density of a neutral picture part and the output are obtained in accordance with read picture information. When a curve 4-2 indicates relations between the density and the output, an erase rate for a density x is determined on a basis of curves 4-1 and 4-2; and if this erase rate is, for example, 40% for a density x1, the area of the latent image part is set to Z or the latent image in 0.4Z area part is erased. Digital erasing is performed in accordance with this determined erase rate.
