IPC: B29C45/68
Filed: 1984-08-21
Abstract: PURPOSE:To detect the contact of a moving platen with a mold and to enable automatic mold thickness adjusting operation by a method wherein a motor is stopped by the time-up signal of the timer which is set with the drive of the motor and reset by the output signal of a driven member operation detector. CONSTITUTION:The mold thickness adjusting mechanism 2 connected to the shaft 1 of a motor M moves a moving platen to come in contact with the mold. When the motor M is driven and an output pulse signal from the proximity switch 8 of a sensor S are counted, a counter 12 is reset in every set value and a timer 13 is reset and the timer 13 does not output while the mold does not come in contact. However, when the mold comes in contact and the movement of the mold thickness adjusting mechanism 2 or the movement of the moving platen is stopped, the movement of the motor shaft 1 is stopped as well, pulses are not inputted from the sensor S to the counter 12, the count is stopped and no output is produced. Accordingly, the timer 13 operates the indicating device 15 at its set time to indicate the mold to come in contact.

IPC: G11B15/17
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To prevent the selling of an illegal copy of information recording medium by providing in advance a nearly planar LC resonance circuit on the normal recording medium. SOLUTION: When a video cassette tape 10 is inserted into a video deck 1 from the cassette inlet/outlet port 2 of the deck 1, an LC resonance circuit 20 provided on the case 11 of the tape 10 is resonated by a radio wave transmitted from a transmitting-receiving section 3 and a resonant wave is generated. When the resonant wave is not received by means of the section 3, a control section 4 discriminates the tape 10 as a copy and ejects the tape 10 as it is from the port 2. When the resonant wave from the surface of the case 11 is received by means of the section 3, the frequency of the resonant wave is analyzed. When it is confirmed that the frequency coincides with one reference frequency as a result of comparison, the control section 4 discriminates the tape 10 as a proper product and instructs an information reproducing section 5 to make normal reproducing operations.

Abstract: PURPOSE:To resolve a fear that a film is left unphotographed or a power source voltage is wasted and a motor is worn down, by correcting a prescribed time related to the change of a driving mode or warning with power source voltage information of the motor. CONSTITUTION:When a release button is pressed in to the first stage, information of a prescribed time T2 attained by correcting a reference time Tm with digital conversion information Tv of a power source voltage VB and digital conversion information Tt of a temperature sensor is outputted to a T2 memory.

Title: Data transfer circuit
Inventor: ANDO KAZUMASA
IPC: G11C11/409
Filed: 1995-07-10
Abstract: PROBLEM TO BE SOLVED: To output the output signals by the same enabling signal and to dynamically hold the output signals when the enabling signal is inhibited in order to reduce the charging/discharging currents of buses. SOLUTION: The signals are outputted to the buses BUS0 to BUSn-1 from the tri-state buffers 120 to 12n-1 while an output enabling signal E0 is kept at '1'. When the signal E0 is changed to '0', the buses BUS0 to BUSn-1 are set in the dynamic holding states. Then the output data transition detection circuits 110 to 11n-1 detect the changing buses. The detected buses are short- circuited to a dummy signal line 15 by the control signals sent from the output data transition extension circuits 110 to 11n-1 . The short-circuited signals are set in the dynamic holding states and their electric charge are continuously shifted until these signals have the same potentials. When the signal E0 is set at '1' after the shift of the electric charge is over, the analog switches 130 to 13n-1 are turned off and at the same time the signals are outputted from the buffers 120 to 12n-1 .

Filed: 1984-08-21
Abstract: PURPOSE:To prevent an unnecessary label from being issued by issuing a label on condition that gross weight decreases below 0g temporarily and then the load on a counter pan varies by more than a specific value and becomes stable. CONSTITUTION:The charge balance consisting of a counter pan 2, measuring part 3, label printer 4, keyboard 6, setting switch 13 for interlock switching, display device 15, etc., is provided with the automatic processing circuit which consists of a CPU20, I/O block 21, ADC22, etc. Further, the gross weight is below 0g unless an article is placed on the scale plate, so a 0g confirmation flag is set to ''1'' and the condition of label issue is satisfied, so a label is issued when an article is placed to place a load. Thus, the label is issued and then the 0g confirmation flag is set to ''0'', so that no label is issued even when the scale plate 2 is touched with a hand. Consequently, only one label is issued for each article and no unnecessary label is issued.
