IPC: C08G63/00
Filed: 1980-02-25
Abstract: PURPOSE: To stabilize a glycol soln., by a method wherein when the glycol soln. as a polycondensation catalyst is prepd. by dissolving an antimony compd., a cobalt compd. and a phosphorus compd. in a glycol, a specified amount of an acid is added to the glycol soln.  
     CONSTITUTION: When a glycol soln. as a polycondensation catalyst for the production of polyesters is produced by dissolving 1W3wt% antimony compd. (e.g. antimony trioxide), 0.05W2wt% cobalt compd. (e.g. cobalt acetate) and 0.1W5wt% phosphorus compd. (e.g. phosphoric acid) in a glycol such as ethylene glycol, 0.3W 1.5wt% acid (e.g. acetic acid, hydrochloric acid or sulfuric acid) is also added to said glycol soln. By this addition of the acid, the glycol soln. is stabilized so that deposited materials are not formed during storage.

Title: Automatic clock phase adjustment circuit
Inventor: MIKAMI KYOKO
IPC: H03L7/00
Filed: 1991-01-24
Abstract: PURPOSE:To eliminate the need for the phase adjustment by a manual operation. CONSTITUTION:A phase comparator 3 compares the phase of a 1st clock signal 1 with the phase of a 2nd clock signal 2. A mean value detecting circuit 4 detects the mean value of an output signal of the phase comparator. An A/D converter 5 converts the output signal of the mean value detecting circuit 4 into a digital signal. A delay variable element 6 uses the output signal of the A/D converter 5 as a control signal to delay the 2nd clock signal 2. Thus, the phase of the 2nd clock signal 2 is adjusted to the phase of the 1st clock signal 1 automatically.

IPC: H01L29/417
Filed: 1980-02-27
Abstract: PURPOSE:To reduce ON resistance of insulation gate FET of high pressure-resistance by providing an offset region between a channel and a drain in and on a substrate semiconductor and by laminating three or more layers of semiconductor having different conductive types between adjacent layers. CONSTITUTION:There are N<+> type source and drain 2, 3 in a P type Si substrate 1. An N<-> layer 9 and a P <-> layer 10 are piled, an N type intermediate layer 11 is provided, and thereby a gate region and an offset gate region of multilayer structure are connected, through which current is made to flow. By flowing high-resistance layers of P<-> and N<-> into offset gate regions alternately in this way, the N<-> layer is depleted between the parts of the P type Si substrate of the P layers, absorbing the rise of voltage. When the density of impurity of the P<-> layer is selected properly and the layer is depleted completely between the same and the adjacent N<-> layer at the time of rise of the drain voltage, the fall of pressure resistance of the drain due to the multilayer structure can be prevented. By this constitution, it becomes possible to increase the N<-> high-resistance layers through which current flows, to lessen the resistance of the offset gate regions and to reduce the ON resistance of the element.

Filed: 1985-02-08
Abstract: PURPOSE:To obtain the stabilized laser beams by a method wherein a circuit is controlled on the basis of the photo output of the title diode detected by a photo reception means and a specific set value selected by a selection means, so as to set the photo output of this diode at a specific set value. CONSTITUTION:The semiconductor laser diode 1 is driven by a laser drive circuit 2 and releases laser beams. The output beam is partly transmitted to a photo reception part 3 and detected as the monitor current IM. On the other hand, a sink current IS corresponding to a desired set value is released out of a constant sink current source 4. The relation in size between both currents IM and IS is detected by an error current detector 5. In the case of IS<IM(ISIM), using the difference DELTAI, the amplification in a direction in which the photo output of said diode 1 is reduced (increased) is carried out by an amplifier 6. As a result, the laser drive circuit 2 acts to reduce (increase) the photo output of this diode 1. Through the above-mentioned process, the photo output of the laser diode 1 stabilizes at a desired value.

Title: Evaluation of semiconductor crystal

IPC: H01L21/66
Filed: 1990-02-05
Abstract: PURPOSE:To contrive to determine whether an inplane superlattice formed on a minutely inclined surface is good, by measuring the energy and strength of scattered particles while changing the angle of incidence of an ion particle beam. CONSTITUTION:First, the position of a substrate is adjusted so that ion beam 15 impinges from the [001] direction. In this state, all surface group III atoms 13 and 14 exist in the position 'visible' for the ion beam 15 so that a shadow cone 16 arises within a crystal and the strength of ions scattered by Ga atoms 14 is almost equal to that of ions scattered by Al atoms 13. Then, when the substrate 11 is rotated (rotation angle is theta) and the direction of incidence of the beam 15 begins to deviate from the [011] direction, Al atoms 13 existing in the lower part in close proximity to the difference in level on the substrate enter inside the shadow cone 16 by Ga atoms 14 right above the difference in level to 'disappear'. The strength of the ions scattered by Al atoms 13 weakens but that of the ions scattered by Ga atoms 14 does not change.
