Title: Phase control circuit
Inventor: MURAKAMI HITOSHI
IPC: H02M1/08
Filed: 1990-03-15
Abstract: PURPOSE:To make it possible to output pulses having phase corresponding to a phase control command by providing a phase control circuit with a frequency detecting section for outputting a frequency signal having effective interval proportional to the frequency of a rectangular signal and updating the count of a counter only during the effective interval. CONSTITUTION:Upon fluctuation of the frequency of an AC power supply 2, e.g. when the frequency of a voltage EA is doubled, a counter 4e reads out a phase control command CS at time t5. Since the effective interval of a frequency signal EN is doubled in a frequency detecting section 4d at this time, the count CNT is counted two times faster than the interval between time T3-T4 and reaches a maximum count at time t6 and a pulse PL is outputted. Consequently, the interval t5-t6 is reduced to half of the interval t3-t4, and when it is expressed in terms of phase angle, phase lags at times t4 and t6 are equalized.

Title: Measuring device of contact resistance between conductors and manufacture thereof
Inventor: IDO YUKIO
IPC: G01R27/08
Filed: 1990-03-15
Abstract: PURPOSE:To make uniform the current density of a current flowing through a contact region between conductors, by forming a conductor film on an insulating film having a first opening and by forming thereon an insulating film having second and third openings. CONSTITUTION:A contact resistance between a first conductor film 4 and a second conductor film 8 which are in contact with each other in a second opening 6 form in a second insulating film 5 is measured. When a voltage is impressed between the conductor film 8 and a fourth conductor film 10 formed on the rear side of a semiconductor layer 1, a current flowing through a contact region between the conductor films 4 and 8 passes through a first opening 3 formed to be in the same size with that of the opening 6 or in the size approximating thereto in a region opposite to the opening 6 in a first insulating film 2 and flows to the conductor film 10 through the semiconductor layer 1. Accordingly, the current flowing through the contact region between the conductor films 4 and 8 advance straight without the direction thereof being curved and the current density in a contact interface is uniform substantially. As the result, the contact resistance between the conductor films 4 and 8 can be measured accurately.

Title: Developing method
Inventor: TAJIMA HATSUO
IPC: G03G13/08
Filed: 1987-03-17
Abstract: PURPOSE:To prevent deterioration of an image by decreasing the amt. of a developer to be coated on a developer carrier with an increase in the toner concn. of the developer in a developer container. CONSTITUTION:The toner concn. in the developer after development is detected by a toner concn. detecting sensor 62. A replenishing roller 63 begins to rotate to supply the toner when the toner concn. is low. However, the developer of the high toner concn. exists further in the developer container 36 and an immediate decrease in the toner concn. does not occur in the case of stopping the toner replenishment as the toner concn. increases sufficiently high. A spacing between the tip 601 of an auxiliary control plate 60 and a developing sleeve 22 is, thereupon, narrowed to decrease the amt. of the developer to be coated on the sleeve 22. The amt. of the developer to be supplied to the developing region is thereby decreased and the suppression of the density of a copied image right after detection of the toner concn. is permitted.

Filed: 1995-03-23
Abstract: PURPOSE: To correspond to a high speed communication rate by using the both of buffers for transmission and reception for transmission or for reception at the time of the transmission and reception in half-duplex communication. CONSTITUTION: When a serial communication controller 10 is used in full-duplex communication, the control signal inputted in a switching means 22 is set to a high level. Buffers 14a to 14d for reception and buffers 18a to 18d for transmission are used for reception and for transmission, respectively and separately. When the controller 10 is used semi-duplex communication, the control signal inputted in the means 22 is set to a low level and the controller 10 is made the one for semi-duplex communication. As a result, all the buffers 14a to 14d and 18a to 18d are functioned as buffers for reception at the time of a reception and buffers for transmission at the time of a transmission.  Therefore, the buffers for reception and for transmission of the same number as the number of conventional buffers can be used as the buffers for reception and transmission of the twice numbers as many as the number of the conventional buffers.
