摘要:
A non-contact IC card, a non-contact IC card terminal and a non-contact IC card system for performing data communication between the IC card and the terminal by using electromagnetic waves are arranged so that the IC card can reliably receive data transmitted from the terminal once the IC card is started up by a startup signal from the terminal. A selection circuit, under the control of a CPU selects a receiving amplifier having a smaller amplification factor in a startup step for receiving the startup signal and a receiving amplifier having a larger amplification factor in a data communication step for exchanging data signals. The sensitivity with which the data signal is received is thereby increased relative to the sensitivity with which data signals are received.

A switch system for an automotive vehicle enables the driver to properly operate various devices mounted on the vehicle without reducing or limiting the driver's field of view to any practical extent. In one form, the switch system includes a plurality of switches for operating various devices mounted on the vehicle; a switch selection detector for detecting which one of the switches is selected by a driver; a display for displaying the result of a driver's switch selection detected by the switch selection detector as well as the operating conditions of the devices as a result of the driver's switch selection; and a reflector in the form of a half mirror provided at a location above a dash board for reflecting the contents of the display so that the driver can watch the displayed contents of the display as reflected on the reflector. In another form, the reflector is omitted and the display is provided at a location above a dash board and below the driver's sight line through a front windshield so as not to reduce the driver's forward viewing field through the windshield so that the driver can watch the displayed contents of the display while watching the road ahead.

This invention relates to a distributed feedback semiconductor laser which achieves distributed feedback by gain coupling by providing periodical changes in the thickness of the active layer (5) or the absorptive layer, and aims to achieve light distributed feedback mainly of periodical perturbation of the gain factor by diminishing the periodical perturbation of refractive index caused by the changes in the thickness of the active layer (5) or the absorptive layer. This invention is characterized by a refractive index canceling structure comprising a combination of layers (6) and (7) of different refractive indices to cancel periodical changes in refractive index caused by the periodical structure of the active layer (5) or the absorptive layer.

A hair cosmetic composition comprising fine particles of a crosslinked polymer, which are insoluble in water and ethanol and do not form a film at normal temperature, is disclosed. A conventionally known film-forming polymer may also be formulated optionally. The hair cosmetic is free from stiffness, stickiness, or excessive gloss imparted to the hair which are the defects of conventional hair cosmetics using only conventional film-forming polymers, and provides excellent hair conditioning and hair-resetting effects.

摘要:
A semiconductor integrated circuit is capable of being supplied with battery current information and battery voltage information. The semiconductor integrated circuit includes a memory function, a current integrating function, a voltage-based state of charge operating function, a current-based state of charge operating function, a comparison determination function, a correcting function, and a resistance deterioration coefficient output function. The memory function stores the relation between a state of charge of a battery and an internal resistance deterioration coefficient thereof. The full charge capacity outputted from the correcting function and the internal resistance deterioration coefficient outputted from the resistance deterioration coefficient output function are stored in the memory function when a voltage-based state of charge and a current-based state of charge compared by the comparison determination function are determined to substantially coincide with each other.
摘要:
A drive controller for driving an inductive load connected to a node between first and second switches connected in series with a direct current voltage source includes a first diode, a series circuit of a second diode and an inductor, and a control circuit. The first diode is a parasitic diode of the first switch and connected in antiparallel with the first switch. The series circuit is connected in parallel with the first diode. The control circuit drives the inductor load by applying a control voltage to the first switch before applying a first ON-voltage to the second switch. The first ON-voltage turns ON the second switch. The control voltage is greater than zero and less than a second ON-voltage. The second ON-voltage turns ON the first switch. The control voltage causes the first switch to operate in weak inversion.

The present invention suppresses reductions in inspection precision caused by reflected and scattered light produced by wafer holders. In a wafer holder (10) that has protruding support parts (11) that contact and support a wafer and groove parts (12) that are separated from the wafer, the protruding support parts (11) are extended continuously from a part that supports one edge of the wafer to a part that supports the other edge of the wafer. Connecting parts (13) that connect adjacent protruding support parts (11) are provided in each of the vicinity of the parts supporting the one edge and the vicinity of the parts supporting the other edge.
