Title: Small-loss high-speed transistor
Inventor: NANTOU KENJI
IPC: H03K17/60
Filed: 1983-03-11
Abstract: PURPOSE:To attain a device which has less loss for switching transition to cause no secondary breadkown phenomena and does not generate a large loss even if a large current is flowed, by allowing a bipolar transistor TR to take charge of a steady large current and allowing a field effect TR to take charge of a transient current. CONSTITUTION:An FET 4 and a bipolar TR 5 are connected in parallel, and a Zener diode 6 is inserted in series to the base of the bipolar TR 5 to make its voltage coincident with the threshold voltage of the FET 4. Meanwhile, a capacitor 3 is connected between the gate and a source S of the FET 4, and a parallel circuit consisting of a diode 1 and a resistance 2 is inserted in series to the capacitor 3, and the operation is delayed only on the turn-off side. Values of the resistance 2 and the capacitor 3 are so determined that the time constant determined by them is longer than the switching time of the bipolar TR 5. By this constitution, a steady loss is generated in the bipolar TR 5 not to flow a current to the FET 4. The FET 4 takes charge of a transient loss, and the bipolar TR is not turned on or off with a high voltage.

Title: Laser beam condensing device
Inventor: SUGII MASAKATSU
IPC: H01S3/101
Filed: 1995-02-03
Abstract: PURPOSE: To prevent reflected light from a laser beam irradiation surface of a beam from advancing into a lens barrel. CONSTITUTION: By painting the laser beam irradiation surface of the beam 15 with laser beam high absorption paint 18, a laser beam L is absorbed by the laser beam irradiation surface of the beam 15, so that the reflected light from the laser beam irradiation surface of the beam 15 is prevented from being multiply reflected in the lens barrel 4 and becoming stray light. Since the beam 15 is provided with a cooling path for making a cooling medium circulate in its interior, the heat of the beam 15 is taken away and the beam 15 is cooled by the cooling medium in a pipe even when the laser beam L is absorbed and the temperature of the beam 15 rises. As a result, the thermal deformation of the beam 15 caused by absorbing the laser beam is restrained.

Title: Method of levelling surface of semiconductor
Inventor: REENDERUTO DE BURUIN
IPC: H01L21/3065
Filed: 1989-02-20
Abstract: PURPOSE: To flatlen the surface of a semiconductor element having complicated initial local level difference to a satisfiable extent by determining a moment of time when a first process is interrupted based on a moment of time when a CO discharge line to be generated by plasma is increased abruptly when two kinds of substance (dielectric and resin) are subjected to etching simultaneously. CONSTITUTION: A semiconductor element is coated with a relatively thick silica glass based dielectric layer 20 and the surface thereof is not flat but has a level difference. In order to flatlen the surface of the dielectric layer 20, the element provided with a resin layer 21 is subjected to stepwise etching from the free surface 22 through action of gaseous ionized species generated by plasma. Simultaneous etching of two kinds of substance is performed in two stages of process. When a plasma gas is supplied, quantity of oxygen for fluorocarbon compound is set higher during second process than during first process. The moment of time when the first process is interrupted is determined based on the moment of time when a CO discharge line to be generated by plasma is increased abruptly.

IPC: H04B7/15
Filed: 1982-03-15
Abstract: PURPOSE:To improve an S/N ratio by mixing an input freqency signal with the output of a voltage-controlled oscillator, by performing phase comparison between said output and a reference frequency, and then by driving the voltage- controlled oscillator by the output of the phase comparison. CONSTITUTION:A pilot received signal fPR is inputted to the 1st mixer 3. The output of the mixer 3 is mixed with the output of a voltage-controlled oscillator 10 by the 2nd mixer 15, whose output is supplied to a phase detector 7 for phase comparison together with the output of a reference frequency oscillator 11 through a BPF16. A transmission intermediate frequency signal arrives at a terminal 21 and is mixed by a transmitting mixer 23. The output of the mixer 23 is mixed with the output of a transmission pilot signal generator 25, which outputs their mixture. Since the output of the mixer 3 and that of the oscillator 10 are mixed, the band width of the BPF16 is narrowed down and the S/N ratio is increased.

Abstract: PURPOSE:To provide chemical resistance and extremely high water resistance, by providing a layer comprising a protective composition based on polyvinyl alcohol having a carboxyl group introduced thereinto and a polyamide epoxy resin on a thermal developing layer. CONSTITUTION:A paint containing a leuco dye, an electron receiving substance and a binder is applied onto a support and dried to form a thermal developing layer.

Abstract: PURPOSE:To attain a stable white background without influences upon a heating electrode by not making the heating electrode white but forming a white insulating layer on the upper face of a heating electrode layer. CONSTITUTION:A heat insulating and electric insulating layer 2 is formed on a lower glass substrate 1. A photomask is put on an Al film to be an electrode, and this film is exposed and developed, and thereafter, an electrode pattern of a heating electrode 3 is formed by etching or the like. The white insulating layer is formed by sputtering or the like, and the mixture rate of impurity gas out of sputtering conditions is dominant when an SiO2 insulating layer is made white. If the mixture rate of impurity gas is raised, the insulating layer becomes cloudy to be made opaque, and therefore, the reflection factor of the specular surface is reduced, and a white insulating film 7 is obtained.
