Abstract: PURPOSE:To obtain a coated cemented carbide tool capable of being used under a severe working condition such as pin-milling and the like with long life maintained by chamfering a cutting blade as specified, and thereby making the minimum value of the coated film thickness at the chamfered section thinner than 60% of that for the other section of it. CONSTITUTION:A cemented carbide base material 4 which is a formed tool for pin-milling is made up from cemented carbide, and around honing is processed onto a cutting blade so that the chamfered section 3 is formed at its blade edge. In order to strengthen it without impairing wear resistance, suitable chamfering in size has to processed. In order to improve the cutting blade in strength in addition to the aforesaid chamfering, only the coated film at the chamfered section of the cutting blade has to be made thin. Only the coated film at the chamfered section 3 of the cutting blade is processed so as to be regulated by means of honing and the like without decreasing the coat in thickness as a whole so that the minimum value delta1 of the coated film thickness at the section shall be less than 60% of that of the other section of it.

Title: Motor-driven winder of camera
Inventor: YOSHIDA TADAHIRO
IPC: G03B17/00
Filed: 1984-02-24
Abstract: PURPOSE:To rewind automatically a film without any sensation of suddenness by releasing a shutter release button from being pressed and then starting the rewinding operation. CONSTITUTION:When a switch S4 is turned on with a switch S2 on while the shutter release button is still pressed after exposure, the film begins to be wound. A switch SM3, however, is turned on at the end of the film and the output of an inverter IN6 goes up to H to stop a motor, so that no reversing signal is outputted. When the switch S2 is turned off by freeing the release button, potentials at points (b) and (b') of a decision circuit J rise gradually to H through the operation of a capacitor C3, but the potential at the point (b) is higher than that at the point (b') in a transient state, so the output (e) of the circuit J goes down to L. state. At this time, the potential at a point (a) is at L when the winding of the film is incomplete, so the output of the inverter IN4 goes up to H and a reversing signal is applied to the motor to start rewinding the film.

Title: Sterilizing method by high-voltage pulse
Inventor: HATTORI RYUICHI
IPC: C02F1/48
Filed: 1990-02-15
Abstract: PURPOSE:To effectively sterilize the microorganisms in fluid without using a large quantity of electric energy by once stopping the impression of high- voltage pulses after the impression of the high-voltage pulses to a liquid surface, then impressing the high-voltage pulses again to the liquid surface. CONSTITUTION:The method for sterilizing the microorganisms contained in the liquid by impressing the high-voltage pulses to the surface of the liquid to be treated includes a stage for impressing the high-voltage pulse, a stage for halting the impression of the high-voltage pulses and a stage for impressing the high-voltage pulses after the halt of the impression. The sterilization effect is higher as the pulse voltage of the high-voltage pulses is higher but the large- scale device is necessitated and such device is economically disadvantageous if the pulses of the excessively high voltage are used and, therefore, the pulse voltage of 5 to 50kV, more preferably 29kV may be used if the distance between an electrode and the surface of the liquid to be treated is, for example, about 5mm. Various pulses of square waveforms, peak waves, sine wave, etc., are usable as the high-voltage pulse waveforms to be impressed. The square wave among these pulse waveforms are more preferably used.

Abstract: PURPOSE:To record time information as making it synchronize and coincide with ATIP by providing a synchronizing signal generating means, a time information comparing means to obtain difference between the previously recorded time information detected by a detecting means and the desired previously recorded time information, and a counting means. CONSTITUTION:When the ATIP in an allowable range from the desired absolute time (ATIP: Absolute Time In Pregroove) one ATIP previous to the time information corresponding to a position to start recording is detected by the detecting means 9, it is interpolated and protected as the synchronizing signal of timing in data recording by the synchronizing signal generated from a synchronizing signal generating means 13 and synchronizing with the detected ATIP. Further, the signal of unit time is generated from a unit time generating means 8 by this synchronizing signal, and the generated signal of the unit time is counted by the counting means 12 up to the number of the unit time obtained by the time information comparing means 11. Accordingly, the timing of the time information one ATIP later than the desired ATIP and corresponding to the position to start the recording is obtained. Thus, the recording can be executed by making the ATIP and the time information of a subcode synchronize and coincide correctly.
