This slide switch includes: a casing formed in a hollow box shape with an open top; several fixed contacts on the bottom surface of the casing and several terminals connected to them extending to the outside of the casing; a cover mounted to close the open top of the casing, formed with a hole opposed to the fixed contacts; and a slide member disposed inside the casing, which has a control portion protruding out through the hole in the cover and a movable contact portion made of a resilient electrically conducting material which bears against the internal bottom surface of the casing and thereby produces a biasing force on the slide member to impel it in the direction towards the cover. The movable contact portion of the slide member, according as the control portion of the slide member is moved from outside the casing, selectively connects together a combination of the fixed contacts. The movable contact is mounted to the slider so that movement of the contact within a plane parallel to the bottom surface of the casing is solely restricted to the sliding direction of the slider.

A slide switch has a switch operating member at its upper surface which is slid back and forth for operating the slide switch. An adapter is provided for operating this slide switch from the side, and has a main body which has a base and clamp members extending from opposite sides of the base to define a space between them, the clamp members being adapted to grip the slide switch between them so as to secure the adapter on the top of the slide switch with the slide switch being held at least partly in the space between the clamp members. The adapter has an actuator pivotally fixed to the main body, and this actuator has a lever portion which protrudes out from the main body to the side and an actuation portion which, with the slide switch held between the clamp members, engages with the switch operating member of the slide switch, so as to slide it as the actuator is pivoted with respect to the main body. As a result, the slide switch, which ordinarily is for operation from its top, can be converted to be operated from its side.

The movable contact portion of the slide member, according as the control portion of the slide member is moved from outside the casing, selectively connects together a combination of the fixed contacts. By this seal member being provided, a good sealing performance for the switch is available, and therefore, when the switch is soldered to a printed circuit board and a cleansing fluid is thereafter used for cleansing off solder residue, no contamination is introduced into the slide switch.

This electronic component of the rotary switch type may include: a casing; a disk shaped rotor, rotatably supported in the casing, and formed with a cam pattern system; a contact system which is actuated by the cam pattern system as the rotor is rotated; and a sheet spring. The sheet spring has: two pressure portions; a substantially flat portion, intermediate between the two pressure portions, which is stressed so as to press the two pressure portions against the cam pattern system as the rotor is rotated, for providing detent action for the rotor; and a fixing portion, fixed to the casing, and proximate and connected to the substantially flat portion. There may be two each of the substantially flat portion and the fixing portion. As a specialization, this sheet spring may be generally ring shaped with a generally circular interior outline and a generally square exterior outline, and its two pressure portions may be two of its diagonally opposed corner portions which are creased so as to define projections opposing the cam pattern system, while its two substantially flat portions may be the other two of its diagonally opposed corner portions which are creased so as to press its two pressure portions against the cam pattern system. Also, this electronic component may include a resin casing with a terminal passing through it and a hole formed through it from its surface to the terminal, with some thermosetting bonding agent filled into the hole and sealing the terminal to the casing.

An apparatus for diagnosing a fault in a semiconductor device includes an laser applying unit, a detection/conversion unit, and a fault diagnosis unit. The semiconductor device is held at a state where no bias voltage is applied thereto. The laser applying unit then applies a pulse laser beam having a predetermined wavelength to the semiconductor device so as to two-dimensionally scan the semiconductor device with the pulse laser beam. The detection/conversion unit detects an electromagnetic wave generated from a laser applied position in the semiconductor device, and converts the detected electromagnetic wave into a time-varying voltage signal that corresponds to a time-varying amplitude of an electric field of the electromagnetic wave. The fault diagnosis unit derives an electric field distribution in the semiconductor device on the basis of the time-varying voltage signal to perform fault diagnosis on the semiconductor device.

A magnetic cassette recorder is disclosed which has a microprocessor having stored therein a standard recording level. Inputting a signal representative of an actual amount of attenuation being offered by a level control rheostat to the input record signal, and a signal representative of the amplitude of the record signal that has traveled through the rheostat, the microprocessor computes the actual amplitude of the record signal before being attenuated by the rheostat. When the thus computed amplitude of the input record signal exceeds the stored standard amplitude, the microprocessor puts out a control signal for adjusting the rheostat to the standard amplitude. The standard recording level stored in the microprocessor is manually variable by switches to the liking of the particular user.

A detection apparatus includes a sample holding section, an irradiation means, a detection means, a calculation means, and an evaluation means. The irradiation means irradiates a substance held in the sample holding section with a THz wave. The detection unit detects a THz wave that has passed through or been reflected from the substance. The calculation unit determines a frequency dependence of a property of the substance with respect to the irradiated THz wave and then calculates a slope of a straight line or a slope of a straight line obtained by straight-line approximation of the frequency dependence of the property of the substance. The evaluation unit evaluates the state change of the substance by comparing a previously-obtained slope of a straight line of the frequency dependence of the property of the substance in a standard state and the slope of the straight line of the substance calculated.

A microswitch, comprising: a casing consisting of a base casing half and a cover casing half; a plurality of terminal pieces received, at their intermediate parts, in slots provided in the base casing half and extending substantially perpendicularly from a surface opposing a corresponding surface of the cover casing half; a contact mechanism accommodated in a cavity in the casing and electrically connected to the terminal pieces; and a push-button member elastically supported by a spring member and projecting out of the casing for actuating the contact mechanism by movement of the push-button member; the terminal pieces being provided with projections extending from their leading edges, and the slot being provided with a recess for receiving the projection; wherein the slot comprises an external part and an internal part which is narrower than the external part, and a projecting length of the projection is larger than a depth of the internal part. Thereby, the projection may be easily fitted into the recess because the terminal piece is still in the broader part of the slot and can be easily shifted at this stage, but, once the projection is received in the recess, the terminal piece is securely held in position by the narrower part of the slot.
