Title: Lcd scrolling mechanism
Inventor: HAABEI UON
IPC: G06F3/048
Filed: 1992-08-19
Abstract: PURPOSE: To provide an automatic offset mechanism which can always handle the 1st line of an LCD as a line 0 without knowing the actual physical address of RAM data/information. CONSTITUTION: An LCD vertical scroll mechanism traces the address of information scrolled automatically on the LCD. When a frame signal is received, a counter 12 is initialized to a value latched in a vector register 14. A following BPCLK signal steps an adder 16 through a series of values. Those values are repeated by a segment driver through two bus selectors 22. One of bus selectors 18 is connected to a counter which is parallel to a subtracter 20. When the value from the counter 12 exceeds a specific value equal to MUX of the LCD, the subtracter 10 finds the difference between the specific MUX value and the value received from the counter and commands a parallel bus selector to repeat the difference to the RAM of a segment driver. The adder 16 is connected to another bus selector and vector register.

Abstract: PURPOSE:To facilitate connecting a signal source to an output coaxial line and to supply efficiently a switching electric signal in the matching state electrically by supplying the switching electric signal from the external to the electrode part of an optical switch through a microstrip line. CONSTITUTION:When the switching electric signal is supplied from one of microstrip lines 17 and 18, for example, the line 17 and the other 18 is terminated by a load resistance, the switching electric signal is coupled to a slot line 16 from the line 17 and is transmitted in the lengthwise direction of the slot line 16 and is coupled to the microstrip line 18 and goes to the load resistance connected to the microstrip line 18. In this case, the electric field of the switching electric signal is applied to the gap of the slot line 16 to switch the light. That is, the light incident from an optical waveguide 12 goes to an optical waveguide 13 in case of absence of the switching electric signal but is switched to an optical waveguide 14 while the switching electric signal is supplied.

Title: Logical integrated circuit
Inventor: KATO SHUICHI
IPC: H03K17/16
Filed: 1984-11-16
Abstract: PURPOSE:To avoid the simultaneous change of the output levels of all output buffers in a test mode by activating or inactivating successively at the prescribed time intervals the output buffers provided for each output of a logical circuit block. CONSTITUTION:The potential of a control pin C is set at a high logic level and all output buffers OB1-OBm are inactivated. Under such conditions, the desired signals are impressed to input pins I1-In. Thus an internal logic state of a logical block LG is set. Then the potential of a low logic level is impressed to the pin C, and buffers OB1-OBm are activated successively by a control circuit CG. Under such conditions, a tester produces a strobe signal and fetches output signals from output pins O1-Om to inspect them. Then the pin C is set at a high logic level to inactivate the output buffers. This avoid the simulta neous change of the output levels of all output buffers.
