Title: Optical recording medium
Inventor: YAMANAKA HIDEO
IPC: G11B7/24024
Filed: 1990-03-13
Abstract: PURPOSE:To lower a surface wobbling acceleration and to provide the excellent adapta bility to driving of a high rotating speed by providing square notched parts in the peripheral edges of the substrates of the optical recording medium of a sticking type having recording layers via an adhesive layer between two sheets of the substrates. CONSTITUTION:Two sheets of the substrates 1a and 1b, with their surfaces having the recording layers positioned on the inner side are disposed to face each other and are stuck via the adhesive layer 2. The outer peripheral edge parts on the inner side of such substrates 1a and 1b are formed with the notched parts 3a and 3b. Namely, the outer peripheral edge parts on the inner side of the substrates disposed to face each other have the step by the notched parts 3a and 3b. The application of a pressure to the notched parts 3a and 3b is low and the strains generated within the substrate planes are relieved therein when the pressure is applied by a press to the substrates at the time of sticking of the substrates. The planes of the substrates 1a and 1b having the recording layers are thereby relatively flattened. There is not much increase in the surface wobbling acceleration in spite of an increase in the rotating speed in this way and the recording medium is hardly affected by a change in the rotating speed of recording, reproducing and erasing. The excellent interchangeability of driving is obtd. as well.

Title: Control system for memory
Inventor: AOKI MASASHI
IPC: G06F3/12
Filed: 1990-03-15
Abstract: PURPOSE:To effectively use a memory by suitably extending or reducing any areas and using the memory to be successively updated when the memory is used while being divided into an area, which is not erased in a normal operation, and the area to be successively initialized. CONSTITUTION:When it is requested to allocate the area of a frame memory (FM) 23, it is decided whether the allocation is for a permanent area (PM) or a temporary area (TM). In the case of the PM, the presence/absence of an idle space in the FM 23 is investogated in an order from a low address (AD) to a high AD. In such a case, when there is no idle space, the processing is finished, and when there is the idle space, one block (BL) of the FM 23 is allocated. Then, the PM end AD allocated for next search is set to a PM search AD 21a and the processing is finished after setting the PM start AD of the PMBL and the PM end AD to a PM pointer. When allocating the TM, the FM 23 is searched in an order from the high AD to the low AD, and when there is the idle space, one BL is allocated from the high AD to the low AD. Then, a TM search AD 21b is set to the end AD of the new BL and the TM pointer is updated. Similarly, the release of the FM 23 is executed by the AD 21a and the 21b and the processings of the PM and TM pointers as well. Thus, both the PM and the TM can be effectively utilized by being suitably extended, reduced and updated.

Abstract: PURPOSE:To smooth the temperature distribution of a battery and improve the charge efficiency by providing such a constitution that the oxygen gas absorptive performance of a negative electrode is more excellent in the outer circumferential side than in the central side, in an electrode group in which a positive electrode and the negative electrode are spirally wound through a separator. CONSTITUTION:Nickel positive electrode 1 and negative electrode 2 are spirally wound through a separator 3 to form an electrode group. A hydrogen storage alloy which is inferior in oxygen gas absorptive performance and has a small average grain size, is used on the central side of the negative electrode, while a hydrogen storage alloy which is excellent in oxygen gas absorptive performance and has a large average grain size, is used on the outer circumferential side. Hence, exothermic reaction is mainly caused on the outer circumferential side easy to release heat and reduced on the central side difficult to release heat. Thus, the temperature distribution in the battery is smoothed, the charge efficiency of the positive electrode is improved, and a reduction in capacity can be suppressed. By reducing the temperature in the battery, the deterioration of the negative electrode is suppressed, and cycle characteristic is improved.

The tip of the tapered end is cut into a semi-circular shape with a pivot hole as a breakpoint. The series of slats are fitted to the back side up to the outermost slat. Then, the tip of the pivot is fastened by a nut to structure the frame of the sunshade. The sunshade is installed by placing the pivot to the upper right/left corner of the windshield by the vehicle roof. Further, each slat is provided with a drawer at the tapered end gradually. This drawer is pressed by the starting device on the outermost slat, the series of slats therefore open/close.

Title: Image display device for scanning type electron microscope
Inventor: OTSUKA SHINOBU
IPC: H01J37/22
Filed: 1987-03-20
Abstract: PURPOSE:To make it possible to display in a high expansion and in a high view field in a same image screen at a time by making the magnification display devices different in the X direction and in the Y direction crossing square to the X direction, and displaying at a time. CONSTITUTION:When the magnification in the Y direction is wanted to make larger than that in the X direction, the output amplitude of the Y direction deflecting signal variable circuit 10-2 is made smaller than that of the X direction deflecting signal variable circuit 10-1 to make the width of the electron beam scanning in the Y direction shorter than that in the X direction. As a result, an image expanded in the Y direction is displayed on the CRT 14. On the contrary, when the magnification in the X direction is wanted to make larger than that in the X direction, the output amplitude of the X direction deflecting signal variable circuit 10-1 is made smaller than that in the Y direction deflecting signal variable circuit 10-2. Since the magnification in the X direction and in the Y direction of the sample image can be set at will, a high expansion and a high view field image can be displayed in a same image screen at a time.
