Title: Manufacture of semiconductor device
Inventor: SUGAWARA FUMIO
IPC: H01L21/76
Filed: 1987-04-30
Abstract: PURPOSE:To avoid the creation of steps or the like in a field oxide film and obtain the field oxide film of required form by a method wherein, after nitrogen ions are implanted into a pad silicon film formed on a silicon substrate beforehand to form a silicon nitride layer, an aperture is formed and then the field oxide film is grown in the aperture. CONSTITUTION:After a pad oxide film 2 and a pad silicon film 3 are successively formed on a silicon substrate 1, nitrogen ions are implanted into the pad silicon film 3 to form a silicon nitride layer 4 in the surface side of the pad silicon film 3. Then, at least the silicon nitride layer 4 is etched to form an aperture 5. A field oxide film 7 is grown in the aperture 5 in a high temperature oxidizing atmosphere. After that, the silicon nitride layer 4, the pad silicon film 3 and the pad oxide film 2 are removed by etching. For instance, after the aperture 5 is formed, channel stop implantation for avoiding inversion is applied to the aperture 5 side of the substrate 1 to form an impurity implanted layer 6 and then the field oxide film 7 is grown on the impurity ion implanted layer 6.

Title: Modulator modulating digital signal
Inventor: BOEHM MANFRED DR
IPC: H04L27/36
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To increase a transmission capacity of a digital signal without changing a band width of a transmission channel. SOLUTION: A modulator has a controller(CTRL) that assigns a digital signal to be sent to some carrier frequencies in a transmission channel. In the most simple case, on the occurrence of a bit sequence 01, a 2nd carrier frequency (f2) is sent without transmission of the 1st carrier frequency (f1), and on the occurrence of a bit sequence 11, both the carrier frequencies (f1, f2) are sent simultaneously. Thus, two bit sequence sets are assigned to the two carrier frequencies of the transmission channel. On the occurrence of the bit sequence 11, it is not required to send the carrier frequency twice continuously, and thus the transmission capacity is increased.

Title: Memory access system
Inventor: KINOSHITA JIRO
IPC: G05B19/18
Filed: 1995-04-28
Abstract: PURPOSE: To accelerate read access from a master unit to the memory of a slave unit. CONSTITUTION: A read request is inputted to a read request transmitting means 1a. The read request transmitting means 1a discriminates whether the address of that read request is continued to the address of the last read request or not. When the address is not continued, that read request is transmitted to a slave unit 2 but when the address is continued, an address match signal is outputted to a read data control means 1b. A memory access control means 2a transmits the first data of the address shown by the read request and the second data of the next address to a master unit 1. The read data control means 1b transfers the first data as read data and stores the second data in a buffer 1ba.  When the read request is further outputted to the continued address in such a state and the address match signal is inputted to the read data control means 1b, the second data in the buffer 1ba are transferred.

Title: Method for separating
Inventor: EIKI YOSHIHIRO
IPC: B01D15/08
Filed: 1992-04-24
Abstract: PURPOSE:To excellently separate fullerenes by using the C18 column (a column filled with a filler prepared by chemically coupling an octadecyl group) of high-speed chromatography and a hexane/lower alcohol mobile phase. CONSTITUTION:At the time of separating fullerenes (C60, C70, C78, etc.), a system containing a mixed solution of hexane and lower alcohol is used as a mobile phase. For example 2-propanol, ethanol, etc., can be used as the lower alcohol. When the lower alcohol is added to the mobile phase, a sharper peak can be obtained. In addition, the elution can be delayed (retention can be intensified) when the adding amount of the lower alcohol is increased.

Then it transmits the signal to the city water pipe interface 4b of a ultrasonic wave communication equipment 1b on a reception-side via a city water pipe interface 4a, a branch pipe 7a, the city water pipe 7, and a branch pipe 7b. Since the ultrasonic wave communication equipment 1b on the reception-side is in a reception state, a ultrasonic wave reception part 5b operates through a transmission/reception switch 3b, and receives the sound signal in a communication circuit 2b.

Filed: 1985-05-16
Abstract: PURPOSE:To easily mount and remove a tubular diaphragm by opening a blind flange, by forming the diaphragm in a diaphragm pump, operated by oil hydraulic pressure, in an elastic tubular shape. CONSTITUTION:A tubular diaphragm 2, forming its intermediate part in a spindle shape, eliminates the necessity for elongation in the axial direction of the diaphragm when it is deformed, and the diaphragm, being easily deformed, increases durability by decreasing stress of the diaphragm. While the diaphragm, increasing the ability of deformation, serves for forming the diaphragm into compact size. However, the diaphragm uses a material of normal rubber quality. A blind flange 3, being opened, enables the tubular diaphragm 2 to be mounted and removed.

Filed: 1985-05-16
Abstract: PURPOSE:To adjust properly the effect of separation control and high cut control without giving effect on the time constant by providing a DC voltage control circuit changing optionally the ratio of a multi-path disturbance quantity to an S meter control voltage. CONSTITUTION:If multi-path disturbance takes place, a ripple component super imposed on an S meter voltage is converted into a current I1 by a voltage- current converting circuit 16 and the current is compared with a reference current I0 by a current comparison circuit 17. The current difference (I1-I0) becomes a multi-path current. The current becomes a reference current of a current mirror circuit 18 comprising transistors (TRs) Q3, Q4 to produce a mirror current In (=R3(I1-I0)/R4). The current In decrease the base potential of a TR Q2 by InR4 and the output voltage is decreased similarly by the drop InR4. The current value In is controlled by the ratio of resistors R5, R6 and the output voltage is changed optionally by changing the resistance ratio. In this case, the time constant is decided by a constant current I3 and a capacitor C5 and no effect is given on the time constant by changing the resistance ratio to change the voltage drop.
