Abstract: PURPOSE:To improve the privacy and cipher performance of communication by sending a reset pulse of a PN code from a sender side to a receiver side via a telephone line at the start of transmission and resetting the PN code with the reset pulse. CONSTITUTION:A PN code reset pulse generating circuit 10 of a transmission section outputs a reset pulse at the start of transmission, a PN code generator 8 at the sender side is reset and initialized and generates a PN code in response to a clock from a clock generator 7. The reset pulse is sent to a reception section via an interface circuit 11 and a telephone line 12 and a PN code reset pulse generating circuit 19 is triggered via an interface circuit 20, then a reset pulse is given to a PN code generator 22, which is initialized. Thus, the production of the PN code is started in response to the clock from a clock generator 18 synchronously with the sender side. Thus, the privacy and cipher performance of communication are improved and the initial synchronization security is facilitated.

IPC: H01J29/04
Filed: 1987-12-25
Abstract: PURPOSE:To obtain a good image with small power consumption by intermittently heating a linear hot cathode. CONSTITUTION:A linear cathode 2 is intermittently heated. This intermittent heating can be performed, for example, when an electron beam is once emitted, the electron beam is extracted at some potential, then it is kept at the potential on the low potential side for a while without being immediately returned to the heating potential of the linear cathode 2, and it is again returned to the heating potential of the linear cathode 2. The power consumption is considerably reduced as compared with the heating time of the conventional linear cathode, and a good image can be obtained with less power consumption.

Title: Mask for exposure, and production of semiconductor device
Inventor: HASHIMOTO TAKEO
IPC: G03F1/70
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To surely detect exposure abnormality when the transfer of circuit patterns is executed with a scanning type projection aligner. SOLUTION: The patterns are formed by executing exposure by using a mask having check pattern 1 of a rectangular shape arranged zigzag with fine isolated dot patterns 2 in a direction parallel with the operation direction of the scanning type projection aligner. The isolated dot patterns 2 give rise to the deterioration of the pattern shapes sensitively to a fluctuation in process conditions, such as out-of-focus, and, therefore, the easy detection of the exposure abnormality in an inspection stage is possible. The dotty check patterns are small in the necessary area and the increase of a chip area is prevented.

Abstract: PURPOSE:To improve brake operation feeling by installing a controller which controls the operation of a pressure control valve based on signals from a brake operating force direction means and a vehicle deceleration detection means so as to attain vehicle deceleration which fixedly corresponds to operating force. CONSTITUTION:When a brake pedal 11 is depressed and master cylinder pressure reaches a preset value, a circuit for connecting a master cylinder 13 to respective wheel cylinders 15 is divided into a master cylinder side circuit P1 and a wheel cylinder side circuit P2.
