摘要:
A reproducing apparatus for a recording medium on which information signals and information indicating the type of the information signals are recorded includes a housing section, a reproducing section, a carrier mechanism, and a controller. The housing section houses plural recording media. The reproducing section reproduces a recording medium. The carrier mechanism takes out a recording medium from the housing section and carries the recording medium to the reproducing section. The controller controls the reproducing section and the carrier mechanism. The controller controls the carrier mechanism on the basis of category information indicating a genre and information related to a reproduction frequency generated on the basis of reproduction hysteresis information of the recording medium, so as to carry out relocation within the housing section of the recording media housed in the housing section.
摘要:
An electrodeposited wire tool has a core wire extending in a longitudinal direction, a plating layer provided on an outer peripheral surface of the core wire, superabrasive grains held by the plating layer and coating layers covering the outer peripheral surfaces of the superabrasive grains. The coating layers are constituted of electroless Ni—P platings. The coating layers are heat-treated, and the electroless Ni—P platings are partially or entirely crystallized.

An infrared data transmission and reception system capable of avoiding adverse effects due to infrared external noises includes a data transmitting circuit and a data receiving circuit of which the former is so constructed as to add a signal-free region of a predetermined length or a trailer to the terminating end of each of the frames of a data bit pulse train and the latter is so constructed as to discriminate between transmitted data and external noise by detecting whether or not the region corresponding to the trailer is signal-free with respect to a detected output, whereby a proper encoding output is generated on the basis of the discrimination.

Mechanism unit(s) functioning as automatic-feed cassette(s) and mechanism unit(s) functioning as manual-feed tray(s) together form a single integral module, constituting a hybrid paper supply module. A plurality of hybrid paper supply modules are stacked together to constitute a paper supply mechanism. Manual-feed tray(s) with which manual-feed mechanism unit(s) of respective hybrid paper supply module(s) is or are provided is or are maintained in stored state(s) as a result of electromagnetic attraction produced by electromagnet(s). In correspondence to image forming condition(s), electromagnetic attraction at one electromagnet is terminated, causing manual-feed tray(s) to assume deployed state(s). Furthermore, primary path(s) passing vertically through module interior(s) is or are formed so as to permit transport of recording paper toward printing unit(s) of hybrid device(s) regardless of from which hybrid paper supply module(s) it is that recording paper is taken up.

A variable speed driving apparatus drives a plurality of induction machines that facilitates reducing the deviations of the primary magnetic fluxes of the induction machines from the reference and preventing the torque and rotating speed of each induction machine from lowering in the low speed range or when the loads on the respective induction machines are unbalanced. The variable speed driving apparatus includes an inverter 1, induction machines 2, current detectors 3, speed detectors 4, a reference angular frequency operating device 6 for operating the rotating angular frequency of the induction machine bearing the heaviest load based on the output signals of the speed detectors 4, a first phase difference operating device 7.sub.1, for operating the first phase difference between the secondary side component of a reference current and a primary reference magnetic flux, a first reference slip angular frequency operating device 8.sub.1 , to which the first phase difference is inputted, an adder 12.sub.1, for adding the output of the operating device 8.sub.1, and the output of the operating device 6, an integrator 13 for integrating the output of the adder 12.sub.1, a detected current vector rotating device 5 for converting the output of the current detectors 3 to a q-axis component and a d-axis component based on the output of the integrator 13, a q-axis current regulator 10, a d-axis current regulator 11, and a reference voltage vector rotating device 15.sub.1 for converting the reference d-axis current value and reference q-axis current value to reference three-phase voltage values based on the output of the integrator 13.
摘要:
A control system for an electromagnetic valve having a valve element, a pair of solenoids opposed to each other and disposed to drive the valve element in respective directions opposite to each other and between a first extreme position and a second extreme position, and a spring interposed between the solenoids, for biasing the valve element toward a neutral position intermediate between the first and second extreme positions. The solenoids are controlled such that when the valve element is to start moving from one of the first and second extreme positions toward the other extreme position, energization of a corresponding one of the solenoids is terminated, and energization of the other solenoid is started when a predetermined delay time period elapses from the termination of the corresponding one solenoid. The solenoids are also controlled such that they are both energized over a predetermined lap time period during movement of the valve element from one of the first and second extreme positions toward the other extreme position.
摘要:
The operation of an electronic appliance, such as a cassette tape deck, is controlled completely or partially by switch operation. The appliance includes a memory for storage of control information, setting devices, such as switches, for entering the control information, a memory lock or latch for controlling the operating state of the appliance based on the control information supplied from the memory or from the setting devices to the memory lock, and for locking the appliance into such operating state, a display arrangement adapted for display of the setting information and for display of the information in the memory lock, and a setting change display indicator. The setting information stored in the memory can be checked by actuating a check switch, which causes the setting information stored in the memory to be displayed without affecting the operating state in which the appliance is locked. When the operating state is changed by a setting operation while the information previously stored in the memory has been transferred to the memory lock to control the operating state of the appliance, so that the contents of the memory lock (i.e., the operating state in which the appliance is locked) are not coincident with the corresponding information stored in the memory, the fact of such change is displayed on the setting change display indicator. This notifies an operator that the information is being changed, and assists the operator in avoiding unintentional errors.
