Title: Controlling device of cycle for three phase
Inventor: KATAYAMA AKIO
IPC: H02M1/08
Filed: 1980-02-16
Abstract: PURPOSE:To make it possible to do the three phase cycle control by performing zero cross control only on two phase of the three phase AC power source. CONSTITUTION:When at the time of t1 the rectangular wave signal (a) is put into the input terminals (r) and (q) of the zero cross control units 11a and 11b and the first output control unit 10a is continued at the time of t2, the voltage of the wave forms (b) and (c) is impressed on the load 2a and 2b, while the second control unit 10b is continued at the time t3, the balanced voltage of the wave forms (b), (c) and (d) is impressed on the load 2a, 2b and 2c. When at the time of t4 the input of the rectangular wave signal (a) is gone, the output control unit 11a or 11b, which has first become zero voltage of the V phase or W phase, is not continued, the current flows until the time t5 and the voltage of the wave forms (b) and (c) is impressed on the loads 2a and 2b. Thereby using two zero cross switches for single phase the cycle control of the three phase AC power source can be made.

Patent JP-H0670540-A (JP)
Title: System provided with current-limiting output and power supply circuit
Inventor: BARU BARAKURISHIYUNAN
IPC: H03K17/082
Filed: 1993-02-05
Abstract: PURPOSE: To prevent a current from increasing and to obtain accurate current- limiting characteristic by a system, wherein a sense resistor for detecting a load current is connected between a negative input and the ground, a detection voltage thereof is compared with the voltage drop of a control resistor and a switching transistor for power is turned off. CONSTITUTION: An output current passing through a switching transistor 52 passes through a sense resistor 54, connector between the ground and a negative input and generates a sense voltage. Meanwhile, a current passing through a constant current source 56 passes through a current-limiting control resistor 58 and comes to a negative input. At the time when an opposite-end voltage value of the control resistor 58 and a sense voltage value are equal, a non- grounded input terminal of a comparator 60 is made to be at a zero volt. When the output current increases and the sense voltage rises, herein, the output of the comparator 60 turns off the transistor 52 through the intermediary of a logic block 62, so as to limit the output current.  The limited value of the output current can be easily adjusted by a resistance value of the control resistor 58 or by setting of a constant-current source 56.
Patent JP-H02199856-A (JP)
Title: Package for ic
Inventor: KANAMORI SHUJI
IPC: H05K3/30
Filed: 1989-01-27
Abstract: PURPOSE:To prevent an IC from being destroyed by a method wherein external lead terminals whose pitches are different are formed. CONSTITUTION:Each part between leads 1 is at equal distance (b); at least one lead 1' is adjacent to the other lead 1 at an interval (a). These intervals are set, e.g. to a ratio of a/b=2/1. These intervals can be formed easily because it is sufficient to cut off one lead when a lead frame is cut. When intervals A to D of lead terminals are made different, it is possible to prevent an IC from being destroyed because the lead terminals cannot be inserted into electrode parts of a printed-circuit board, a socket or the like when they are being inserted erroneously. When the intervals of the lead terminals are changed in this manner, a positional relationship with reference to a jig or the like for measuring use can be recognized; even it the terminals are inserted erroneously, they cannot be inserted.

IPC: G03B21/11
Filed: 1988-01-29
Abstract: PURPOSE:To shorten a retrieving time by providing a mark retrieving means for detecting a mark put corresponding to an image frame and performing retrieval and a frame retrieving means for detecting the end part of the image frame and performing retrieval and switching both retrieving means. CONSTITUTION:A mark detector 17 possesses a photoelectric converting element and outputs a mark detection signal by disconnecting a light beam from a lamp 14 with the mark (m) when a film F is fed. And the mark detection signals are counted by the counter of the retrieving device. An image detector 23 arranged on the back surface of a screen 18, for example, detects the end part of the image frame 24 from the difference of light receiving quantities between a base film part and the image frame 24. And the optional retrieving means can be selected by switching to either mark retrieving means or frame retrieving means with the aid of a switching means. Thus, an operation for retrieval is facilitated and the retrieving time can be shortened.

Abstract: PROBLEM TO BE SOLVED: To etch silicon oxide films, by including a process for etching thin oxide films while cooling them to a predetermined temperature. SOLUTION: Etching a BPSG film 42 by an anisotropic etching, contact holes reaching respectively n-type regions 38, 39 are created to remove thereafter a resist mask 44. After forming the contact holes passing through the BPSG film 42, naturally oxidized films 45 which may be formed on the bottom surfaces of the contact holes are removed by a plasma down flow processing wherein NF3 is added to the down flow of a gas containing hydrogen and steam. In this case putting a silicon wafer 31 on a cooled stage in a down flow processing chamber, a light etching of the wafer 31 by the down flow is performed while monitoring the average temperature of the wafer 31 by a laser thermometer.  By setting the temperature of the wafer 31 to a low value, the etching amount of the BPSG film 42 is suppressed and the naturally oxidized films 45 on the bottom surfaces of the contact holes can be removed effectively.

Title: Distribution power supply system
Inventor: OWADA KOJI
IPC: H02M7/48
Filed: 1995-01-13
Abstract: PURPOSE: To hold a power conversion unit in a self-supported operation at a failure in power system and return to a system interconnection operation at restoration, by switching the control of an inverter circuit into a current control circuit at the power failure and into a voltage control circuit after the restoration. CONSTITUTION: In a distribution power supply system, a voltage control circuit 8 is added to a current control circuit 7. During operation of system interconnection with power distribution system, an inverter 3 is controlled by using the current control circuit 7. Then, a control changing switch 9 is switched by an interconnection protection unit 11 to control the inverter 3 by the voltage control circuit 8 during the self-supported operation. When the interconnection protection unit 11 judges a failure that arises in power distribution system from a detection signal fed by a system condition detector 12, the control on the inverter circuit 3 is switched from the voltage control circuit 8 to the current control circuit 7, and the current control circuit 7 is changed to the voltage control circuit 8 when the power system is restored.  As a result, a self-supported operation is kept under an abnormal condition, and the self-supported operation is changed into system interconnection operation at its restoration.
