Title: Hair drier
IPC: A45D20/10
Filed: 1992-03-16
Abstract: PURPOSE:To improve operability in combing and drying by changing over warm and cool blasts with the motion of a drier in place of a manual switch. CONSTITUTION:When a power terminal 1 is connected to a commercial power source AC and a power switch 2 is closed, a control circuit 3 monitors the condition of a drier on the basis of the output of a detector 12 to judge whether or not the drier carried out a predetermined operation distinguished from that in the usual use. While 'usual use condition' is judged if the output from the detector 12 per unit time (3 seconds for example) falls within the number of times T of judgment (5 times for example) and 'change-over operation condition' is judged if the outputs exceed the number of times T, the unit time and the number of times of judgment are properly set in consideration of the shape of the drier and the convenience of use for a user. When 'change-over operation condition' (change-over) is judged, the control circuit 3 changes properly the rate of electrification of a heater 6 to hold such condition thereafter until 'change-over judgment' is carried out.

Title: Buffer circuit
Inventor: OKAMOTO SANAE
IPC: H03K17/08
Filed: 1988-03-11
Abstract: PURPOSE:To prevent an overcurrent from flowing into an output buffer circuit by using an overcurrent protecting circuit containing a bipolar transistor whose base receives the output voltage of an operational amplifier performing the input of the output voltage and the reference voltage together with its emitter connected through an end. CONSTITUTION:An overcurrent protecting circuit 2 is set between a power supply terminal of an output buffer circuit 1 and a CMOS transistor TRQC. The circuit 2 contains an operational amplifier OA which supplies the output voltage VO to an non-inverse input terminal and the reference voltage VREF to an inverse terminal and an npn TRTn having a base receiving the operational output voltage Va together with an emitter connected to a CMOS TR and a collector connected to the terminal 6 respectively. Then the OA lowers the base potential of the voltage Va and reduces a transistor current ic in comparison with the voltage VREF. As a result, the flow of an overcurrent is prevented so that the increase of the power consumption, the increase of the load of a power supply system, etc., can be avoided.

Abstract: PURPOSE:To obtain a highly durable and efficient selective absorption surface at a low cost, by bonding a metal foil having a low emissivity over the surface of a base or support, and applying a paint consisting principally of a black pigment and a binder of an acrylic resin over the surface of the metal foil. CONSTITUTION:A metal foil 3 of aluminum, copper or the like, having an emissivity lower than 0.1 is bonded to the surface of an inexpensive base or support 1 (for instance, galvanized steel plate) having a high emissivity by the intermediary of an adhesive layer 2, and a film 4 having a thickness smaller than 5mum is formed over the surface of the metal foil 3 by coating a paint consisting principally of a black pigment A and a binder B of an acrylic resin. Here, more than one oxides or composite oxides of elements selected from Fe, Mn, Cu, Cr, Co and Ni are used for the black pigment A. In general, it is preferable to select the ratio of the weight of the pigment A to that of the resin B at a value within the range of 0.2-0.5, and a value near 0.3 is most preferable. By coating the paint thus obtained over the surface of the metal foil 3 having a low emissivity to have a thickness smaller than 5mum, it is enabled to obtain a selective absorption surface having 0.93-0.95 of solar heat absorptivity and 0.40-0.50 of heat emissivity.

Abstract: PURPOSE:To ensure a faithful output of the picture information even though the DC component of the output signal of a photoelectric converting element varies. CONSTITUTION:Signals (a) and (b) supplied from a photoelectric converting element are supplied to a differential amplifier 16, and the differential between both signals is amplified. At the same time, the noise components of these signals are eliminated and delivered. Furthermore the differential is amplified by an amplifier 17. A peak holding part 18 is actuated with a timing pulse supplied from a timing pulse input terminal 22 and then holds successively the peak value of the output signals of the amplifier 17. A bias control part 20 detects the DC component of the signal from the blanking level, and a bias control signal h3 of a level corresponding to the detected DC component is superposed on a signal h1 supplied from a fixed bias circuit 21 and then applied to the amplifier 16. In such a way, the DC component is excluded from a signal. An AGC part 19 detects the amplitude variations of signals (a) and (b) which are due to the factors other than the picture information out of the output signal of the part 18. Then the unit of the amplifier 17 is controlled in response to the detection of variations of signals (a) and (b).

Title: Manufacture of thin-film magnetic head
Inventor: HATA HIDEKAZU
IPC: G11B5/31
Filed: 1982-04-09
Abstract: PURPOSE:To size a magnetic yoke to accurate depth by forming a triangular marker for depth size control which has one side parallel to a work ending line on a substrate previously and performing guidance regarding the distance of other two sides of the marker during grinding work. CONSTITUTION:The triangular markers 20 for depth control which each have one side set parallel to the work ending line 100 are formed previously on the substrate 10 laterally close to the magnetic yoke 18. Those markers 20 are congruent isosceles triangles on both sides of the magnetic yoke 16. During grinding work, parallelism is held by making corrections so that width lXA, is equal to lXB in a figure. Since the width (l) of a magnetic thin film 16 is set equal to the distance between two sides of the markers 20 on the work ending line 100, size lX from a gap surface is measured on the basis of ltantheta/2 to perform calculation lXtantheta/2-l.tantheta/2, finding the depth. Thus, when the work advances almost to the work ending line 100, polishing work is started. The polishing work is completed when the lX becomes equal to the width (l).
