Title: Data transmission system using ultrasonic wave
Inventor: TAKAGI MIKIO
IPC: H04B11/00
Filed: 1984-12-24
Abstract: PURPOSE:To attain the accurate transmission of data with no confusion of data by transmitting the collected data after converting them into the ultrasonic wave signals. CONSTITUTION:In case each unit data contained in the digital data consists of 8 bits, this unit data of 8 bits is divided into two parts, i.e., the first half of 4 bits and the second half of 4 bits respectively. Then a fixed transmission time interval T1 is set between both divided data of 4 bits each. At the same time, a fixed transmission time interval T2 is set also between unit data transmitted successively. In this case, both intervals T1 and T2 are different from each other. Then each divided data is converted into the excitation duration time T3 corresponding to the data contents. A fixed time T4 set in consideration of the rise time during which a piezoelectric element 26 is excited then an ultrasonic signal is radiated, is added to the time T3.

Title: Tape player
Inventor: OHASHI TAMAKI
IPC: G11B15/10
Filed: 1989-10-25
Abstract: PURPOSE:To stabilize an action by preventing the switching action of a head channel changeover switch when a rewinding lever moves forward. CONSTITUTION:By moving the rewinding lever 3 forward, the switching action of a switching means 20 in a tape traveling direction is allowed but the switching action of the head channel changeover switch 80 is prevented by actuating a preventing means 87. In such a state, the tape is switched to a reverse direction and intermusic detection is performed. According to the detec tion signal, a holding mechanism works to release a state where the rewinding lever 3's moving forward is kept, so that the lever 3 moves backward. In such a process, the switching means 20 is actuated again and the tape is restored to an original forward direction.

Inventor: MURAKAMI KENICHI
IPC: G06F11/28
Filed: 1987-10-31
Abstract: PURPOSE:To accurately grasp the degree of evaluation of a program to be evaluated by applying a system where the rate is measured for the instructions carried out at least once or more during evaluation of said program. CONSTITUTION:A system consists of an input device 1 which performs the input operations, a program comprehension rate measuring device 2, a CPU 3, a main memory 4, and an output device 5. The executed instruction area information is successively stored in the executing processes of programs 41-4n to be evaluated by means of a branch instruction interruption. Then the ratio of the executed instructions of the programs 41-4n is calculated based on the stored executed instruction area information after execution of the programs 41-4n. Thus it is possible to measure the ratio of the number of executed instructions as a program comprehension rate with no work applied to the programs 41-4n. As a result, the degrees of evaluation of the programs 41-4n can be accurately grasped.

Title: Ic memory card
Inventor: TANUMA HIDEYORI
IPC: G06F21/62
Filed: 1993-11-05
Abstract: PURPOSE:To prevent wrong read, write, and erase of an IC memory card by providing the IC memory card itself with a security management function. CONSTITUTION:The IC memory card 10 has a fixed password input buffer 15, and a fixed password peculiar to the card is stored there. The user password from a personal computer is stored in an input password buffer 14 of the card 10. This user password is compared with the fixed password by a control circuit 16 of the card 10 to verify the validity of the user password. In the case of the invalid user password, a ready/busy signal of the card 10 is kept in the busy state and is not changed to the ready state. Therefore, the card 10 doesn't accept the access command when it is issued from the personal computer, thus preventing wrong read, write, and erase.

Abstract: PURPOSE:To prevent the interior temperature of a freezer from rising at the time of defrosting by supplying power to a thermoelectric element whose heat releasing surface is thermally in contact with an evaporator which is detected to have frosted by means of a frost sensor. and providing a control means which operates a solenoid valve incorporated in the refrigerant passage for the evaporator which is detected to have frosted. CONSTITUTION:When a frost sensor 11a detects the frosting, a control circuit gives out a command to close the evaporator side solenoid valve 4a and supplies power to thermoelectric elements 21, 22. As a result, the evaporator 6a which has been detected to have frosted is cut off of the influent refrigerant to stop the refrigerating operation, and the frost on the evaporator 6a is melted away by being exposed to the heat from the heat releasing surfaces 21a, 22a of the thermoelectric elements 21, 22. Meanwhile, the evaporator 6b which is not frosted yet continues the refrigerating operation, and so, the interior space can be refrigerated adequately as a heat absorber 20 is cooled by being taken away its heat by the heat absorbing surface 22b of the thermoelectric element 22. When the frost sensor 11b detects the frost growth, a sole noid valve 4b on the side of the evaporator 6b is closed, and, at the same time, power is supplied to the thermoelectric element 23.
