Abstract: PURPOSE:To remove a cross-talk component by a method wherein a beam of reflected replay light of a multiple recording medium is separated into corresponding components, they are detected independently and an operation processing operation is executed to a part between signals. CONSTITUTION:Rd represents a reflection factor at a time when no recording operation is executed; Rc, Rb and Ra are reflection factors at a time when lambdab and lambdaa as well as lambdaa and lambdab are irradiated respectively and a recording operation is executed. DELTAR1 (Rb to Rd) not equal to  DELTAR2 (Ra to Rc) and deltaR (Ra to Rb) not equal to  deltaR* (Rc to Rd). At this time, a reflection factor at lambdaa corresponds to a value which has changed Rb to Rd at an amplitude of DELTAR1/2 according to lambdaa (omega1) at a part not irradiated with lambdab. Consequently, a change DELTAR ch1 (proportional  replay output) in the reflection factor at lambdaa is a value which has amplitude-modulated a signal omega by omega2 (a signal at lambdab) and which has superposed the signal omega2. deltaR ch2 at lambdab can be found in the same manner. When xsi...eta are used as cross-talk parameters, nonlinear cross-talk terms corresponding to a product exist in a standardized reproduced output in addition to linear terms. In order to reduce a cross-talk component, a specific operation is executed by using respective standardized replay outputs, xsi and eta, and a portion mixed with a piece of information is removed.

Title: Temperature control device for electric carpet
Inventor: TOKUDA HIROBUMI
IPC: G05D23/24
Filed: 1993-11-22
Abstract: PURPOSE:To prevent the quick change of the temperature in a heating segment by controlling the temperature with a newly provided segment selecting switch until the target control temperature is attained because the temperature of a non-heating segment is not lowered to the room temperature and is kept at the high state for some time immediately after total heating is switched to partial heating. CONSTITUTION:When a user selects total heating with a segment selecting switch 7, for example, heaters H1, H2, H3 are set to the drivable state by a switching circuit 8. When the user sets a temperature regulator 6 to a prescribed level, the temperature and control voltage are determined, and a relay 5 is off-controlled based on them. When the user desires to change the total heating to the l/3 heating with the switch 7, for example, only the heater H1 is set to the drivable state by the switching circuit. When a high-level signal is outputted from a comparing circuit 9, a temperature control circuit 3 turns a switch 4 off to interrupt excitation. These actions are repeated to prevent uncomfortableness and a sense of incompatibility.

Abstract: PURPOSE:To prevent the physical quantity from increasing as the reliability of a bus interface part is improved by performing the error detection of the bus between a control part and an arithmetic part in the direction vertical to the respective bits of the bus. CONSTITUTION:A control part 10 reads a microcode out of a control storage(CS) 11 and converts it into an arithmetic part instruction code, and sends this instruction code out to the arithmetic part 20 through an instruction bus 30. At this time, vertical parity codes are generated in vertical parity generation parts 14 and 21 on the basis of the arithmetic part instruction code. When a parity decision instruction 19 in the CS 11 is read in, a control part 10 sends the generated vertical parity code out to the arithmetic part 20 through the instruction bus 30 and also outputs a parity decision signal 15 indicating the period of parity decision making through a buffer 17. The arithmetic part 20 receives this signal 15 and compares the parity code with a parity code generated in itself, and makes an instruction bus parity error signal 25 effective when they do not match each other.
