Title: Control method of cycloconverter
Inventor: MATSUTAKE MITSUGI
IPC: H02M5/27
Filed: 1987-03-12
Abstract: PURPOSE:To improve a power-side power factor by controlling each converter so that the ripple factor of output voltage is reduced in response to output voltage from a cycloconverter. CONSTITUTION:In a cycloconverter consisting of two-step cascade-connected converters, the connections of an input transformer to the converters are con nected so as to form phase difference of 30 deg. in order to reduce power high frequency on the input side and diminish the ripple factor of output voltage. In asymmetric control, one converter is fixed so as to be brought to maximum output voltage, and output voltage is varied by controlling the other converter. A control block has an output voltage command 10, proportional gains 20, 30, DC biases 40, gate pulse generators 50, voltage gains 60, and output voltage 70. Accordingly, the quantities of biases by the DC biases 40a, 40b are changed in an extent that output-voltage pulsation can be allowed, and the cycloconverter is controlled so as to improve a power factor while reducing the ripple factor of output voltage.

IPC: G02B5/20
Filed: 1993-03-16
Abstract: PURPOSE:To provide the process for production of the color filter which is small in the light reflection from light shielding parts and has a flat surface. CONSTITUTION:This process for production of the color filter consists in forming transparent colored layers 2R, 2G, 2B of three colors in the pixel parts on a transparent substrate 1 consisting of a glass plate, uniformly forming a transparent resin layer 3 consisting of a quinone diazide photosensitive resin, etc., exhibiting a property to be dyed by generating a -COOH group by irradiation over the entire surface including the transparent colored layers with UV light, then selectively irradiating the parts corresponding to the inter-pixel parts of the transparent resin layer by UV light and dyeing the exposed parts to black, thereby forming the light shielding parts 3a. The color filter obtd. by this process has the low reflectivity of the light shielding parts 3a and since there is no need for providing the light shielding parts as a separate member, the surface is flattened and since the transparent resin material exhibiting the property to be dyed by exposure processing is applied, the production stages are simplified.

Title: Data communication method
IPC: H04Q9/00
Filed: 1992-03-13
Abstract: PURPOSE:To cope with emergency processing without impairing ordinary process data collection and the transmission processing of control output in spite of serial communication by preparing one transaction for emergency output without using the command response transmission of all three transactions within one micro cycle in constant periodic processing. CONSTITUTION:Periodic data transmitted from a remote PI/O 2 to a control station 1 side is sent by setting on first and second transactions by a periodic data input/output part 22, and is extracted by an other side periodic data input/ output part 14. Also, similarly, data transmitted in the reverse direction is sent by setting on the first and second transactions by the periodic data input/ output part 14, and is extracted by the other side input/output part 22. The data transferred between the station 1 side and the PI/O is updated and reflected mutually in a constant period by performing cyclic scan transmission. Data transmission is performed by executing processing as asynchronous communication by setting a communication frame for emergency output in the command response transmission of a third transaction of micro cycle sent out immediately after an emergency output request.

Title: High frequency switching circuit
Inventor: MATSUURA HIROYUKI
IPC: G01R33/36
Filed: 1983-03-31
Abstract: PURPOSE:To operate the circuit at a board frequency band without requiring circuit space by coupling densely the primary circuit of which a transmission/ receiving coil is connected and the secondary circuit to which a control current is applied by means of a transformer. CONSTITUTION:When the control current Ic reachs 0 at the secondary circuit at the transmission mode, the primary coil L1 acts like a high frequency choke with high impedance, and when a high frequency power output from a transmitter is applied to a high frequency input terminal 12, only the path of an input/ output terminal 14 for transmission/receiving coil is turned on. When the control current Ic is a positive current I0 at the secondary circuit in the receiving mode, the impedance of the primary coil L1 is made very low in terms of high frequency and only the path of the input/output terminal 14 and a detecting signal output terminal 15 is turned on. Thus, no circuit space is required and the circuit is operated at a wide frequency. Then, the high frequency switching circuit with less loss is realized by a simple circuit.

Title: Control method for internal combustion engine
Inventor: FUKAYA HIROYASU
IPC: F02D45/00
Filed: 1980-04-25
Abstract: PURPOSE:To perform control excellently by memorizing the indicated amount of a degree of establishment in a method of feedback control having a learning function. CONSTITUTION:In the method of control having a learning function, the amount of control is found by using the indicated amount of a degree of establishment showing the degree of approach to a target value of control, a value of feedback control employed in the past and a current value of feedback control. In this way, the amount of control reflects the value of feedback as it is in the region where the value of feedback control is established. In addition, in the region where the value of feedback control is not established, the surrounding value of feedback control is reflected on the amount of control. Thus, the amount of control is computed constantly as if an amount of feedback control turned to be the target value of control.

Title: Scanning optical system by semiconductor laser beam
Inventor: TATENO KIMIO
IPC: G02B26/12
Filed: 1982-04-07
Abstract: PURPOSE:To make the adjustment of an optical system easy by forming said system in such a way that the beam made incident to two prisms is paralleled with the beam emitting therefrom, and reducing and stopping down the diameter of the beam having the narrower spread angle in the semiconductor laser beams by the effect of the two prisms thereby spotting the same to a circular shape. CONSTITUTION:The beam from a light source 1 is condensed with a coupling lens 2, and passes through prisms 9-1, 9-2, by which the beam diameter within the scanning plane is reduced and the beam arrives at a scanner 3 in the form of moving in parallel with the incident beam. Then, the beam which is made incident to the prisms and the beam which is going to be emitted are both in parallel with the scanning plane; therefore, the adjustment thereof is easy. Since the beam is refracted twice with the two prisms used, each prism is required to have a small reduction ratio. There is also the advantage that the prisms 9-1, 9-2 are not always required to be the same.
