Title: Converter
Inventor: TAKENAKA KENJI
IPC: H02M7/48
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To reduce distortion of an output current by controlling, with the predetermined means, an output of a frequency converting circuit connected to a secondary coil of a high frequency transformer forming a resonance type inverter and a resonance driver for driving in resonance a switching element. SOLUTION: A high frequency voltage switched by a switching element is supplied to a primary coil of a high frequency transformer 16 and a secondary voltage is generated on a secondary coil through conversion of high frequency voltage to the predetermined level. The secondary voltage is rectified and is then converted to an alternate current(AC) of 60Hz by a frequency converting circuit 19. Structure to form a high frequency voltage to be supplied to the high frequency transformer 16 is formed of only one switching element 12 and a resonance capacitor 14. As explained above, the switching element 12 is connected to the primary coil of the high frequency transformer 16 and the resonance capacitor 14 is connected to both ends of the primary coil. Thereby, the high frequency voltage waveform is changed to the resonance waveform and less amount of electromagnetic noise is generated.

Abstract: PURPOSE:To prevent paper jamming and unjust deterioration on processing ability even in the case a paper is fed from a paper feeding port by which a paper size can not be recognized by controlling the recording mode switching of a recording paper and timing for feeding the paper again in the case of both-side printing based on detection output information. CONSTITUTION:The paper size is set to a maximum paper size capable of being printed on a manually paper feeding port in the case printing is required. When a trailing edge sensor 118 detects the leading edge of the paper, a paper size detecting timer is started. Then, the sensor 118 detects the trailing edge of the paper, the timer is stopped. The time prescribed by the timer is compared with the time for each paper size stored in a memory so as to detect the size of the carried paper. Paper feeding timing for the other side of the paper in the case of the both-side printing can be controlled by storing the size of the fed and carried paper detected by the sensor 118.

Abstract: PURPOSE:To evaluate the resistance of the integrated circuit to the characteristic deterioration of an element by measuring the characteristics of active elements constituting the integrated circuit deteriorating owing to radiation irradiation and the characteristics of the integrated circuit and comparing the deterioration quantities of both characteristics. CONSTITUTION:The evaluation device is provided with a device which measures the characteristics of the active elements and the characteristics of the integrated circuit, a ray source which irradiates the integrated circuit with radiation, and a computation device having a computing means for finding parameters for evaluating the resistance of the integrated circuit to the characteristic deterioration of the elements.

Title: Dust collector
Inventor: MATSUMOTO KUNIO
IPC: F04D29/70
Filed: 1983-01-14
Abstract: PURPOSE:To reduce the dimension of the captioned apparatus and obtain high vacuum degree and large amount of wind by forming a long and a short discharge flow passages on the outer periphery of a fan and arranging the communication ports to the discharge ports formed at the terminal edges of the above-described flow passage, at the center corner part of a box body and obtaining high vacuum degree by means of a long discharge flow passage and a large amount of wind by means of a short discharge passage. CONSTITUTION:The air which is filtered by a filter 70 is discharged from a centrifugal fan 40 and flows into a flow passage 51, communication hole 61, flow passage 52, communication hole 62, discharge flow passage 53, and a communication hole 63, and is discharged from a discharge port 12. The air which flows into the flow passage 51 is sufficiently decelerated, since the flow passage to the communication hole 61 is long, and said air is efficiently transformed from dynamic pressure to static pressure. The air which flows into the discharge flow passage 52 and 53 generates little frictional loss on flow passage wall 55 and 56, since each flow passage to the communication holes 62 and 63 is short, and a large amount of wind can be obtained. Therefore, the amount of wind and the vacuum degree which are necessary for improving the dust collection efficiency of a dust collector can be obtained efficiently by the combination of the flow passage 51 and the flow passage 52 and 53.

Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To reduce consumption of a battery by increasing a connection rate of communication between slave sets while conducting standby to a master set and standby to a slave set in parallel and reducing an ON-time of radio section power supply. SOLUTION: When slave sets (PS11, 12) are resident in a service area, they recognize the structure of an outgoing logic control channel sent periodically by master sets (BS1, 2) to receive an incoming call signal of its own group. The master sets (BS1, 2) provides time information in an incoming call signal of all groups sent from them and inform time information received from a main device (exchange) to the slave sets (PS11, 12). Thus, all the slave sets in the service area can match the time. Based on the reception time, inter-slave set communication call and waiting are conducted to limit a time. Furthermore, a caller slave set obtains the incoming call signal timing of all groups from the structure of an outgoing logic control channel to conduct inter-slave set communication call and waiting limited at a timing elapsed by a time (P*1TDMA) from the incoming call signal based on the interslave set communication call number of the called slave set and awaits a call from the master set for an idle time.
