Title: Error restoring method
Inventor: CLOUTIER JOSEPH E
IPC: H04L1/18
Filed: 2000-05-24
Abstract: PROBLEM TO BE SOLVED: To shorten the time for retransmitting an error information block (e.g. deteriorated frame) and to improve the throughput of a communication channel where information is transported by applying a data puncture operation to information transmitted by a communication system, based on information on a received signal.

Filed: 2000-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a developer concentration measurement device for wet type printing machine which can measure the concentration of developer so that it becomes the actual concentration even when the developer is contaminated. SOLUTION: This measuring device includes a housing 50, a developer oil film forming means arranged at the housing 50 so as to form a developer oil film, a light source unit 81 for irradiating the oil film of the selected color developer with color light corresponding to a wavelength area whose light transmissivity is relatively low with respect to the selected color developer and a sensing means 86 provided corresponding to the unit 81 and including a photodetector receiving the light transmitted through the developer oil film. Thus, since the concentration of the developer is measured by irradiating the thin developer oil film with the color light in the wavelength area having the relatively low light transmissivity with respect to the selected color developer, the effect of the other mixed color toner is relatively small.

Title: Semiconductor integrated circuit and is control method
Inventor: TOMITA HIROYOSHI
IPC: G11C29/04
Filed: 2000-06-06
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit in which an internal circuit can be operated at high speed, in technology by which operation speed of a semiconductor integrated circuit is increased. SOLUTION: A command take-in circuit 1 takes in a command signal deciding circuit operation synchronizing with a clock signal, and outputs it as an internal command signal. An address switch circuit 2 receives a command signal and permits transmitting an address signal to an internal circuit. An internal circuit 3 receives an address signal before taking in a command signal, and starts to operate. Consequently, the internal circuit 3 can be operated at high speed. Also, the address switch circuit 2 receives an internal command signal or a clock signal, and prohibits transmission of an address signal to the internal circuit. Therefore, even if an address signal is changed after a command signal is taken in, the internal circuit 3 is never operated as changing. Therefore, power consumption is reduced.
