Title: Detection of power factor of inverter output current
Inventor: NISHIYAMA SEIJI
IPC: G01R21/133
Filed: 1990-06-25
Abstract: PURPOSE:To eliminate a comparator as hardware for detection of voltage phase and to contrive miniaturization and space saving by providing a current detector in the main circuit of an inverter. CONSTITUTION:A part of DC intermediate bus for the voltage type inverter is separated to the 1st bus connected with main circuit switching elements T1-T6 and the 2nd bus connected with antiparallel diodes D1-D6, and the current detector 3 is provided at the side of 1st bus bar. The output of detector 3 is inputted to a CPU 5. When a voltage output command signal which is selectively given to each switching element of the main circuit of inverter, is received by an interruption pulse generator 6 from the CPU 5, the interruption pulse is generated with the timing when only the switching element of a certain one phase is made ON and supplied to the CPU 5. When the interruption pulse is received by the CPU 5, the output of detector 3 is inputted and a zero-cross point of the current is detected. In the CPU 5, the timing when the voltage of a certain phase becomes 0 can be known from the timing when only the switching element of a certain one phase is made ON, therefore, the power factor of inverter output current can be detected by obtaining the phase difference between the interruption pulse generating time point and the zero-cross point of current.

Title: Serial interface circuit
Inventor: NAKAMURA RYUTA
IPC: H04L12/70
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To enable transmission/reception while making the data of a large capacitance into packets and to enable smooth processing by generating a request packet from a present node to the other node, sending it to a serial interface and detecting split time out when the packet of a response to the request packet is not returned within preset time. SOLUTION: A pending detection circuit 1261 detects whether the response from the other node is under pending or not and when pending is detected, a detecting signal S1261 is outputted to a split time counter 1262. When the detecting signal is received, the split time counter 1262 starts time measuring operation. When the time of the split time counter 1262 reaches the set time of a time out register 1263, a time out signal STO showing split time out is outputted from a comparator circuit 1264. Thus, for example, communication operation is stopped and an error is displayed.

Title: Portable type data processor
Inventor: MIHARA YASUTSUGU
IPC: G06F15/02
Filed: 1991-07-08
Abstract: PURPOSE:To correctly charge by providing a storage battery, connecting means for connecting to an exterior so as to charge, a normally ON relay to be controlled by a driving circuit connected across the battery, and a power source controller. CONSTITUTION:When a charger is connected to a charging port 2 to start charging, a driver 31 becomes active by a charging current, and a switch 32 is opened. Thus, since a voltage of a storage battery 1 is not applied to a power source controller, a power source is not turned ON by a power switch. Then, when charging is completed, a trickle charging is conducted, and a current is 1/50-1/30 of the charging current during charging. If the operating current of the driver of a relay is selected by considering a difference of the currents, the driver 31 becomes inactive during the trickle charging, and the switch 32 becomes ON. Thus, the power source is not turned ON during the charging, but after the charging is completed, the power source can be turned ON.

Title: Semiconductor laser array device
Inventor: HAMADA TAKESHI
IPC: H01S5/40
Filed: 1984-08-08
Abstract: PURPOSE:To obtain the titled device of high output with a large spot ellipticity by a method wherein an N-epitaxial layer is laminated on a P type substrate having a projection, and groove bottoms are made to reach the substrate by forming three parallel ridges; successively, a P-layer, an active layer, and the like are successively laminated. CONSTITUTION:A mesa is formed in the <011> direction by etching the (100) plane of the P type GaAs substrate 1, and an N type blocking GaAs 2 is deposited to a flat surface. The parallel ridges are provided in the <011> direction, thus making grooves among the ridges located on the mesa and the groove bottoms reach the substrate 1. Next, a P type Ga1-xAlxAs clad layer 3, a Ga1-yAlyAs active layer 4, an N type Ga1-xAlxAs clad layer 5, and an N type GaAs layer 6 are laminated, and ohmic electrodes 7 and 8 are attached. Light generated in the active layer 4 by conduction is absorbed to the substrate above the ridges and confined in the grooves, where stable lateral mode oscillation can be obtained. Since the groove interval is very narrow to almost the same degree as the width, beams produced above the grooves become spots of high output in long-elliptic form by the superposition of skirts. This laser array is effective in information erasure.
