Abstract: PROBLEM TO BE SOLVED: To prevent scoring of substrate surfaces and stably contain the substrates by providing a recess holding the substrate laid flat and forming a step at the side face of the inside wall and projections having a curved face at the rear face respectively. SOLUTION: A tray 10 is provided with a circular recess 11 in plan view, for containing a substrate. A circumferential step 12 is formed at the side face of the inside wall of the recess 11 and about three projections 13 having a curved face are formed to protrude downward at the rear face. And about two vertival grooves are formed at the outer peripheral part of the recess 11. The front surface 22 of the substrate 20 is turned down and the slope face 21 for preventing etching of the outer peripheral face is disposed to contact the step 12 and the substrate is contained flatly. In this case, a jig holding the side face of the substrate 20 can be easily taken in/out owing to a vertical grooves formed at the outer peripheral part of the recess 11. When the tray 10' is stacked, the projections 13 are brought into contact with the rear face 23 of the substrate 20 in the tray 10. The substrate surface can be protectively packed by mounting a reinforcing plate on the stacked trays 10, 10'.

Title: Program division load system
Inventor: MAEZONO KAZUO
IPC: G06F9/445
Filed: 1990-10-09
Abstract: PURPOSE:To evade the useless application of a memory by recording the load request generated times for each division unit and releasing a real memory assigned to the division unit loaded earliest when the total memory capacity used by plural loaded division units exceeds the upper limit level of the available memory capacity. CONSTITUTION:A load time recording part 20 records the load request generated times in a division unit control table 70 and gives a processing request to a division unit selection part 30. The part 30 calculates the total value of the memory capacity used by the loaded division units by reference to a load state 74 of the table 70. When this total memory capacity exceeds the upper limit level of the available memory capacity, the division unit having the oldest load time is selected by reference to the column of a load time 75 of the table 70. Then a real memory releasing part 40 releases a real memory assigned to the selected division unit. Thus it is possible to effectively evade the useless application of a large memory capacity at execution of a large scale program.

Title: Semiconductor memory device
Inventor: NISHINO YOICHI
IPC: G11C17/00
Filed: 1985-12-02
Abstract: PURPOSE:To reduce the necessary area of a memory cell and to improve integration density by storing information by utilizing the state of a crystalline or amorphous columnar body formed projecting from the main surface of a semiconductor substrate. CONSTITUTION:The columnar body 5 is formed of a crystalline or amorphous semiconductor while projecting from the main surface of the semiconductor substrate 1. This columnar body 5 is a conductor when crystalline. When pulse current is fed thereto, on the other hand, the columnar body 5 is fused and solidified instantaneously and part or the whole of the columnar body 5 becomes amorphous to turn into a high resistance body. Thus, the difference in resistance value accompanying the change in the internal state of the columnar body 5 is utilized to store information. Fine columnar bodies are principal components, so the required area on the substrate is reduced greatly. Thus, the integration density is improved.

Title: Data storage device
Inventor: YAMAMOTO SHUHEI
IPC: G06T1/00
Filed: 1994-11-02
Abstract: PURPOSE: To store required data by progressing automatically the compression processing or delete processing or the like for data whose processing time comes among data stored in a storage means so as to utilize the storage means within its storage capacity efficiently. CONSTITUTION: Compression/delete time measurement sections 64a, 65a measure a time when each of image data stored in a memory 63d is to be compressed/ deleted based on a storage time stored in a storage time storage section 63c and a time count by a timer 61a. A compression/delete control section 61c gives a command of compressing/deleting data to compression/delete processing sections 64b, 65b when the compression/delete time comes based on the measurement by the measurement sections 64a, 65a. When an operation key 61d inputs the designation of compression/delete inhibit, the control section 61c inhibits compression/delete unconditionally. Thus, a limited storage capacity of the memory 63d is efficiently utilized.

Filed: 1985-11-30
Abstract: PURPOSE:To realize normal storage by dividing a data memory into plural areas and deciding the number of bytes or the number of bits as the processing unit to be accessed at each area. CONSTITUTION:A PROM 5 is divided into plural areas, an area number (00-FF) is given to them, and a byte number being each processing unit of the areas (01-FF), a head address of the areas and the final address of the areas are stored in the area (00) corresponding to the area number. For example, the processing number of bytes, e.g., the area (01) is bytes, the head address corresponds to an address aaa and the final address corresponds to an address bbb. Further, the by the number constituting each area is an integer multiple of the number of bytes adding property information to the number of bytes of the processing unit. For example, since the processing unit number of bytes of the area (01) is 5 bytes, the total number of bytes constituting the area (01) is an integral multiple (l) of 6 bytes. Thus, normal storage is realized.
