A hair clipper has a blade block, which includes a fixed blade, a movable blade overlapped with the fixed blade to make sliding contact with the fixed blade, a pressing spring applying a pressing load to maintain a uniform contact pressure between the fixed blade and the movable blade, and a blade base for receiving and retaining the fixed blade and the movable blade and the pressing spring. The blade base has a blade holder retaining the fixed blade and the movable blade and a blade cover attached to the blade holder to cover the fixed blade and the movable blade. Further, the blade holder has a primary retainer member holding end portions of the pressing spring and the blade cover has a secondary retainer member pressing the end portions of the pressing spring in a direction in which the pressing spring is retained by the primary retainer member.

An intentional offset value is set beforehand. The intentional offset value is larger than a sensing objective signal “sig.” A measuring device is provided for measuring the intentional offset value to obtain a measured intentional offset value “a” representing the quantity of the intentional offset value, and also for measuring a sum of the sensing objective signal “sig” and the intentional offset value to obtain a measured signal value “b” representing a summation of the quantity of the sensing objective signal and the quantity of the intentional offset value. A ratio (b/a) of the measured signal value to the measured intentional offset value is obtained. The obtained ratio is used as noise reducing data for reducing the noise involved in a sensor output.

A semiconductor pressure detection device includes a diaphragm formed at a portion of a P- conductivity type semiconductor substrate having a reduced thickness. Gauge resistors are formed on the surface of an N- conductivity type semiconductor layer formed on the substrate. An N+ conductivity type diffusion layer is formed in the N- conductivity type semiconductor layer to fix the electric potential of the N- conductivity type layer. The first conductivity type area surrounds the diaphragm. Therefore, when the N- conductivity type area is supplied with electric potential, the potential gradient in the N- conductivity type layer is small. Thus, the leakage current which flows to a pn junction between the gauge resistors and the N- conductivity type area is reduced.

A digital-to-analog converter includes an R-2R resistive ladder network having resistors connected in a ladder form in correspondence with a number of bits of a digital input signal. The R-2R resistive ladder network has an output terminal. A pair of positive and negative dc-power-supply terminals are connected to the R-2R resistive ladder network. Currents flowing between the R-2R resistive ladder network and one of the positive and negative dc-power-supply terminals are controlled in response to the bits of the digital input signal to generate an analog voltage signal at the output terminal of the R-2R resistive ladder network. The analog voltage signal depends on the digital input signal. A first resistor and a second resistor located outside the R-2R resistive ladder network are connected in series between the positive and negative dc-power-supply terminals. A third resistor located outside the R-2R resistive ladder network is connected between the output terminal of the R-2R resistive ladder network and the second resistor located outside the R-2R resistive ladder network. A conversion output terminal is connected to a junction between the second and third resistors located outside the R-2R resistive ladder network.

A reciprocatory dry shaver is capable of providing a drive point of transmitting a reciprocating force to an inner cutter from a drive element at a location as close as to a cutting edge of the inner cutter for enhancing cutting performance, yet making the use of a plastic made drive element to give a detachable connection with the inner cutter. The shaver comprises a housing incorporating a drive source which is connected to move a drive element projecting on top of the housing. An outer cutter is supported to the top of the housing. An inner cutter is detachably connected to the drive element and is driven thereby to reciprocate in hair shearing engagement with the outer cutter. The drive element comprises a stud and a pin which projects beyond the upper end of the stud. The inner cutter is formed with a joint for detachable connection to the stud and with a catch for detachable connection to the pin. The catch is formed upwardly of the joint to define a drive point at the connection with the pin where the drive element transmits a driving force of reciprocating the inner cutter. With this arrangement, the driving point can be disposed closer to an upper cutting edge of the inner cutter than a connection point of detachably holding the inner cutter to the drive element. Consequently, a driving force is effectively applied for hair shaving between the reciprocating inner cutter and the outer cuter, thereby enhancing cutting performance.

A hair remover including an outer blade and an inner blade accommodated in the outer blade. The outer blade includes a cylindrical side wall, an upper wall, and a bend connecting the side wall and the upper wall. Straight upper cutting edges and side cutting edges are formed by slits extending from the upper wall to an upper part of the side wall. The inner blade includes a straight upper cutting edge, which is formed at a location corresponding to the upper cutting edges of the upper blade, and a straight side cutting edge, which is formed at a location corresponding to the side cutting edges of the outer blade. The outer blade and the inner blade are formed so as to clip body hair through cooperation between the straight side cutting edges and cooperation between the straight upper cutting edges.

A main body of an inner blade is inserted into an inner blade insertion hole of an inner blade frame such that the main body can extend and retreat, a tip end cutting edge is pushed by a spring such that it comes into contact with an inner peripheral surface of a slit outer blade, the main body of the inner blade projecting outward from the inner blade insertion hole is bent rearward in a rotational direction, and the cutting edge of the inner blade is located rearward of the main body in the inner blade insertion hole in the rotational direction. With this configuration, the cutting edge does not fall forward in the rotational direction, and no gap is generated between the cutting edge and the inner peripheral surface of the slit outer blade.
