Title: Eyesight testing device
Inventor: YOSHIMURA KAZUHIRO
IPC: A61B3/02
Filed: 1991-07-15
Abstract: PURPOSE:To present a target identical in accuracy to a device in which a target is disposed at a position isolated by a distance equivalent to an eye examination distance by making a projected screen a reflective type, and concurrently using a part of the screen as a reflecting member guiding a target projecting beam to the screen. CONSTITUTION:A screen 20 is made of metals, and is of a reflective type. A target beam projected on the screen 20 is reflected by a mirror 19 and a mirror 18, and it is reflected by a mirror 21 thereafter. The target beam reflected upward by the mirror 21 is reflected toward an examined eye by a mirror 22. The mirror 22 is revolved around a mirror shaft 23. A mirror driving plate 28 fitted onto the mirror 22 come in contact with a cam 26 to transmit the action of the cam 26 to the mirror 22, so that the angle of the mirror can be changed. This constitution thereby enables an examinee to see a target at the center section of the mirror even if the direction of a visual axis to the opening section is changed due to change in position for the examined eye.

IPC: G11C11/409
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To enable normal operation with a power source wiring of ordinary wiring width, by successively executing precharge by each one bank or dividedly to suitable plural blanks when the precharge of the entire bank is executed by a collective instruction, thereby suppressing a peak current. SOLUTION: An all bank precharge signal latch 6 is set by an all bank precharge signal outputted via a command decoder 3 and a precharge enable signal is turned to H. As a result, a counter 7 raises a count value from zero to 7 at every frequency-divided clock. At the time of returning to 0, latch 6 is reset, to turn the precharge signal to L. A precharge signal generator 8 forms precharge signals PR0 to 7 by ANDing of the precharge enable signal and the decoding signal of the value of the counter 7. Since the respective banks of a DRAM core 5 deactivate a word line and a sense amplifier in response with the precharge signal input and precharge the bit line, the simultaneous precharge of the plural banks is not executed.
