Abstract: PURPOSE:To prevent a motor of a captioned unit such as a motor for a sunroof of a car and the like from stopping due to acceleration or deceleration by constructing to restrain stopping of the motor on the basis of a protective means against load variations corresponding to the acceleration or deceleration of the car. CONSTITUTION:The load of a driving mechanism is detected by a resistor 40, and compared with reference values set by an addition circuit 80, a memory circuit 140, a timing circuit 150 and a delay detection level check circuit 90 by a comparison circuit 100 and if the loads are over the set values, a motor stop circuit is operated to stop the motor. While, on the other hand, an acceleration or a deceleration is detected by an acceleration converter 300 and is inputted into a comparator 203 via an absolute value circuit 201 to be compared with a set value. If it is over the set value, a transistor 203 is on to intercept the output of the comparator 100 to keep a transistor 121 in off-position to restrict the operation of a motor stop circuit 120. This construction permits to prevent the motor from stopping.

Filed: 1986-03-20
Abstract: PURPOSE:To attain the control of plural computer interfaces having different code systems for control instructions by using a code deciding means, a data holding means, a code decoding means and a signal selection/output means. CONSTITUTION:A control signal selecting/distributing device 4 identifies the codes of the control data on data buses D0-D7 based on a control code system.

Filed: 1984-03-31
Abstract: PURPOSE:To improve the reliability of discrimination by inputting the same optical signal to >=N (N>=2) sets of optical signal transmission lines, synthesizing outputs of each line at the reception side in the same ratio and making it effective when the output is >=1/2 of the total synthesized signals. CONSTITUTION:The same optical signal is transmitted from a transmission terminal in the same output level to >=N sets, e.g., 3 optical signal transmission optical fiber cables 1a-1c. Outputs Pa-Pc from the optical fiber cables 1a-1c are synthesized in the same ratio by a photocoupler 11 of a signal discriminator 10, the output P0 is subjected to photoelectric conversion 12 to produce an output S0. WHen the output S0 is half of the output or over when no fault exists in the optical fiber cables, the signal S0 is discriminated as an effective signal. Thus, the discrimination with high reliability is attained with simple constitution.

Title: Electrode for electron gun
Inventor: ENDO SATORU
IPC: H01J29/50
Filed: 1987-03-20
Abstract: PURPOSE:To obtain a highly accurate focus property even in a large size tube by making the thickness of an electrode plate 0.4 to 1.0 times the diameter of an electron beam passage hole, and forming the thickness of a recessed plate in an even thickness of 0.1 to 0.2 times the diameter of the electron passage hole. CONSTITUTION:At the second grid electrode 1, three electron beam passage holes 2 are formed on a straight line, and around the electron beam passage hole 2, a slit-form recess 3 is formed in the x direction (horizontal deflecting direction). In this case, when the hole diameter of the electron beam passage hole 2 is made D, the thickness of the electrode plate T is set at 0.4 to 1.0 D, and the thickness of the plate at the recess 3 (t) is set at 0.1 to 0.2 D. Since the thickness of the recess 3 (t) is very small as 0.1 to 0.2 D, and the depth of the recess 3 is large, the scattering angle of the electron beams in the horizontal deflecting direction (x direction) is much larger than that in the vertical direction (y direction). Therefore, a highly accurate focus property can be obtained even in a large size tube.

CONSTITUTION:The spectral sensitivity distribution of the green-sensitivity silver halide emulsion layer giving its density DG as follows; DB = DGmin + 0.7, where DBmin is its minimum density, gives the maximum sensitivity Slambdamax at the wavelength lambdamax, which is in the region as follows; 530 nm <=lambdamax<=560nm, and the sensitivity Slambda500 at 500nm wavelength is as high as >=1/4 time the maximum sensitivity Slambdamax, and the sensitivity in 400-460 nm Slambda400-460 is <=1/20 of Slambdamax. The spectral sensitivity distribution of the green- sensitive layer can be easily set in this range by using a sensitizing dyestuff alone or in combination, thus permitting the hue of the bluish green subject to be especially reproduced in high fidelity.

Abstract: PURPOSE: To shorten waiting time for hall-calls in the same direction of deceleration generated after decelerating by a cage-call, by providing a means for setting next operating direction with a means to maintain the operating direction during decelerating.  
     CONSTITUTION: When an elevator arrives at a position to begin deceleration for 4th floor, for example, during ascending to the 4th floor by a cage-call, a hall lantern for ascending is put even if hall-calls asking further ascending in the ascending direction are not existed. When the hall-call in higher floor than the 4th floor is generated while stopping at the 4th floor after the deceleration and during the period between opening and closing of a cage-door, a means reserves against the hall-call. When there are no hall-calls from halls above the 4th floor during the period between opening and closing of the door, the means reserves and answers against hall-calls from halls below the 4th floor.

Abstract: PURPOSE:To perform carrier reproduction by selecting the lead-in phase of the best phase so as to make the bit error rate the best, by selecting one side of I-channel signals and Q-channel signals in the same or opposite phase. CONSTITUTION:A carrier reproducing circuit constitutes a phase synchronizing circuit by feeding back I-channel signals and Q-channel signals which are obtained when synchronous detection is performed on multivalued QAM waves at multipliers 2 and 3 to a voltage-controlled oscillator 13 after inverting or non-inverting the signals and performs carrier reproduction. A switching circuit 9 is the circuit which selects either the I-channel or Q-channel signals for constituting the feedback loop and another switching circuit 11 is the circuit for discriminating whether the signals selected at the switching circuit 9 is to be inverted or left under their own non-inverted state. After selecting each lead-in phase by switching the switching circuits, the one having, for example, the best bit error rate is selected as the one having the best phase out of the lead-in phases and the switching circuits 9 and 11 are fixed to the best phase.

Title: Printing head temperature detector of printer
Inventor: YAMAGUCHI MASAYUKI
IPC: B41J29/377
Filed: 1988-03-17
Abstract: PURPOSE:To detect the temperature of a printing head without being affected by the irregularity of a thermister and thereby allowing a reference temperature to be set to an optimum value by storing a value obtained through the thermister and an A/D converter at a specified temperature, in a non-volatile memory at the time of shipment. CONSTITUTION:At the time of shipment, a control section 1 stores a value D0, which is obtained from a thermister 6 through an A/D converter 5, and varies according to environmental. temperature prevailing then in a non-volatile memory 6 either by operation of keys by an operator or by identification of a control command from a host system. At that time, the operator sets the environmental temperature at T0. Next, during printing process, the control section 1 transmits information on the value which is obtained from the thermister 6 via the A/D converter 5 and becomes more than D0 to a printing control section 3, if such a value increase occurs. The printing control section 3 controls printing action so that adequate time is secured at intervals between printing actions after the transmission of the information. Subsequently, a printing head is prevented from being burnt. As a reference temperature T0 can be detected without being affected by the irregularity of the thermister 6, the reference temperature T0 is set to an optimum value.
