    • Measurements are obtained by a computing unit based on an output Vh from an indirectly-heated constant-temperature controlling flow rate measuring section (16) and an output Vout from a two-constant-point temperature difference detecting flow rate measuring sections (18a, 18b). In the flow rate measuring section (16), a heating element (163) is feedback-controlled based on a detected temperature by a heat sensing element (162) to obtain an output Vh based on the feedback-controlled condition. An output Vout is obtained from flow rate measuring sections (18a, 18b) based on the detected temperature difference between a heat sensing element (182) disposed on the liquid-flow-direction upstream side of the flow rate measuring section (16) and a temperature sensing element disposed on the downstream side. A computing unit outputs as a measurement a flow rate obtained based on the output Vh in a flow rate region where a flow rate is larger than a predetermined boundary flow rate, and outputs as a measurement a flow rate obtained based on the output Vout in a flow rate region where it is less than a boundary flow rate. Accordingly, a flow rate is measured with good precision and sensitivity over a wide flow rate range from a trace-amount flow rate region to a comparatively large flow rate region.

    • A light-quantity adjusting apparatus is disclosed, in which a light-blocking member and an optical filter can be driven with a single actuator, and which can be made compact. The light-quantity adjusting apparatus includes a light-blocking member that changes a quantity of light through an open/close operation within an optical path, an optical filter that can be inserted into and withdrawn from the optical path, independently from the light-blocking member, and a driving mechanism that has a single actuator as a driving source and that drives the light-blocking member and the optical filter. The driving mechanism drives the optical filter by operating the actuator further in an opening direction after the actuator has driven the light-blocking member into an open position, and operating the actuator further in a closing direction after the actuator has driven the light-blocking member into a closed position.

The flow rate sensor includes a flow rate detector having a heating function and a temperature sensing function, and a pipe line for fluid to be detected which is formed so that heat from the flow rate detector is transferred to and absorbed by the fluid. The temperature sensing which is affected by a heat absorption effect of the fluid due to the heat is executed in the flow rate detector, and the flow rate of the fluid in the pipe line is detected on the basis of the temperature sensing result.

A flow rate detecting unit comprising the flow rate detector is retained by the unit retaining portion, and a temperature detecting unit comprising a fluid temperature detector is retained by the unit retaining portion.

    • When a plurality of effects are simultaneously applied to an input audio signal, a plurality of effect-algorithms each for applying solely an effect to the input signal are stored in a memory, and a plurality of combination-algorithms or combination-data which represent combinations of the effects and orders in which effects are applied to the input audio signal are stored in the memory. When one of the combination-algorithms or the combination-data is selected, effect-algorithms included in the selected combination-algorithm or combination-data are selectively read out from the memory. A program for applying effects in a predetermined combination and order is written by CPU based on the read out effect-algorithms and combination-algorithm or combination-data. Receiving the program, DSP successively applies effects to the input audio signal in accordance with the program. As a result, the present effector needs less memory capacity than the conventional effector in which a number of programs consisting of combinations of effect-algorithms are previously stored.A multi-effector comprised of a connection of a digital effect adding device and an analog effect adding device, is provided with a memory having a plurality of memory areas for storing audio signals. An input audio signal, an input signal to the analog effect adding device and an output signal of the digital effect adding device are stored in respective memory areas of the memory. Whether either of input signals is supplied to the digital effect adding device or whether the output signal of the digital effect adding device is input to the analog effect adding device or the output signal is output as a final signal are decided by operation of an externally operated switch. In this way, the order in which effects are applied can be altered independently of the connection of the above two effect adding devices.
