Title: Etching method of semiconductor
Inventor: KINOSHITA HARUHISA
IPC: H01L21/3065
Filed: 1983-01-19
Abstract: PURPOSE:To etch a GaAs region in depth deeper than an AlGaAs region by irradiating mixed gas ions of argon ions and oxygen ions. CONSTITUTION:Ar and O2 are mixed and flowed into a Kaufmann type ion source through two mass flow controllers, ionized and accelerated electrostatically, and irradiated onto the surfaces of GaAs and Al0.3Ga0.7As. GaAs and Al0.3Ga0.7As are etched selectively by utilizing the oxidizing sputtering action of O2 ions. When a mixing ratio of Ar and O2 is approximately 1:1, an etching rate of Al0.3Ga0.7As to GaAs is brought to approximately 0.6 times, and the difference of etching rates is maximized.

Patent JP-S60149293-A (JP)
Title: Apc circuit
Inventor: KATOU SHIROU
IPC: H04N9/83
Filed: 1984-01-17
Abstract: PURPOSE:To obtain an APC circuit of a PAL system whch produces no DP by constituting of a phase comparator, a 1H delay circuit, an adder, an LPF and a variable frequency oscillator. CONSTITUTION:The phse comparison action of a phase comparator 3 is controlled by a burst gate pulse (b) sent from a terminal 2. Then the comparator 3 performs the phase comparison between a color burst signal A contained in a carrier chrominance signal (a) sent from a terminal 1 and the output of a variable frequency oscillator 7. The phase of the signal A repeats +45 deg. and -45 deg. for each line and therefore the output of the comparator 3 has a waveform (c). Thus the output of a 1H delay circuit 4 has a waveform (d) and therefore the output of an adder 5 has a waveform (e). Thus it is possible to remove the factor for generation of a frequency component of 1/2 horizontal scan frequency, i.e., DP which is due to a fact that the phase of the signal A has a shift by 90 deg. every line. This attains an APC circuit of a PAL system which is free from generation of DP.

Title: Manufacture of semiconductor device
Inventor: OOMURA KAZUMICHI
IPC: H01L21/265
Filed: 1978-01-25
Abstract: PURPOSE: To secure the manufacturing process of the semiconductor device which can form a shallow junction with reduced defect by giving the stack of the poly Si on the single crystal Si and then injecting the impurity ion with distribution to both the poly crystal and the single crystal.  
     CONSTITUTION: First, the SiO 2  film is sticked through the heat oxidation or other methods onto the surface of P-type Si single crystal which is inclined within 7 from the (100) face, and then a window is drilled through the photoetching method to expose the Si single-crystal surface. After this, the poly-crystal Si layers are stacked by the pyrolysis. Wafer As or Sb of such structure is doped through the ion injection with such acceleration energy that 5W95% of the total injection amount may be concentrated near the surface of the Si single crystal. This means the injection of 3 × 10 15  ion/cm 2 , and a heat treatment of under 2 hours is given to the test sample in N 2  at 500°C. As a result, the defect caused in the single crystal by the As or Sb ion injection can be recovered, and thus the noncrystal layer is turned into the single crystal to form a shallow junction with reduced defect.

Filed: 1980-01-25
Abstract: PURPOSE:To improve the reflection efficiency of an aluminum film and to improve the brightness of a fluorescent face, by choking only the hole section between fluorescent particles for forming a fluorescent film with an organic film then forming an amulinum film. CONSTITUTION:A fluorescent film 2 formed on a face plate 1 is entirely soaked with water, to remain the water 5 only at the hole section between fluorescent particles 2a. Under this condition fine acryl resin powder 6 having low film forming temperature is dry sprayed. Then the fluorescent film 2 is heated higher than the melting point of acryl particle to condense the fine particle powder 6, thus to form a filming film 7 where the hole between the fluorescent particles is chocked. Furthermore an aluminum film 4 is deposited on the upper face of the filming film 7 and the fluorescent particle 2a to form a fluorescent face. Consequently the reflection efficiency of the metal film is improved and the brightness of the fluorescent face is improved.

Abstract: PURPOSE:To protect a integrated circuit effectively by dividing an abnormal voltage applied to an external input terminal or output terminal by means of a capacitance provided between said terminal and the gate of a protective FET and other capacitances and by using the divided voltage as a gate input voltage. CONSTITUTION:The input terminal N41 or output terminal of MIS IC is connected to the gate of the enhancement type FET Q42 through the capacitance C, and then  the source of Q42 is grounded. The drain is connected to the gate of the first stage  FET Q41 of the protected MIS IC or the source or drain of the output FET, and  further the resistance R4 is put between the terminal N41 and the gate of the first  stage FET Q41 or between the output terminal and the source or drain of the output  FET. As known from the equivalent circuit, an abnormal voltage applied to the  terminal N51 is divided by the capacitance C1 and composite capacitance C0 that  belongs to the contact N44, and voltage across the capacitance C0 is made the gate input voltage of the protected FET Q52. Accordingly the threshold values of the  FET Q42, FET Q52 are not limited, thus the protective operation starting voltage  can be determined only by selecting the capacitance C.

CONSTITUTION:A kneaded starting raw material for forming a carbonaceous material is formed into the prescribed shape of a spring (e.g., coil form). The resultant formed product is then infusibilized and subsequently calcined at 700-3000 deg.C while being heated. The obtained springy material is subsequently reacted with carbon monoxide at 1200-2300 deg.C temperature to convert part or all of a wiry body 2 or plate body of the springy material into silicon carbide and form a part 21 of converted silicon carbide. Thereby, the aimed spring is obtained. Furthermore, the resultant spring is heated in an oxidizing atmosphere to oxidize and remove a part 22 unconverted into the silicon carbide. As a result, the spring having a hollow part 23 in the wiry body 2 can be produced.

Title: Radio communication system
Inventor: MORIYAMA TADASHI
IPC: H04W92/18
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To avoid a voice interruption time in the case of channel switching by transmitting multiplexed control data and voice data to switch channels in the case that speech quality of a speech channel is deteriorated in the radio communication between a master set and a slave set. SOLUTION: Once speech quality has been deteriorated during radio communication using a speech channel between a master set CS and a slave set PS, the master set CS sends control data that designates a switching destination channel to the slave set PS. In the case of sending the control data that designates a switching destination channel, the control data are multiplexed with voice data and the resulting data are sent. According to the method as above, in the case that channels switching is required due to deteriorated speech quality for the communication between the master set CS and the slave set PS, since the control data that designates a switching destination channel are sent while being multiplexed with the voice data, both the master set CS and the slave set PS select the designated channel to start the speech without voice interruption.
