Title: Image forming device
Inventor: TERADA HIROSHI
IPC: G03G15/01
Filed: 1990-01-24
Abstract: PURPOSE:To form a high-definition image without unevenness, roughness and fogging by forming a thin layer of toner particles having nearly spherical shape which perform triboelectrification on a developer carrier with a blade and making the toner fly to an electrostatic image carrier with DC electric field. CONSTITUTION:The toner 28 in a developing device 27 is non-magnetic one component and it is obtained by adding additives such as silica to the spherical toner particles whose mean particle size is about 15 mum. It is conveyed to a stirring blade 31 and sprinkled on the developer carrier 29 at every fixed period. While the toner is electrostatically charged to be positive by a rubber blade 30 with the rotation of the carrier, the uniform thin layer of one or two layers is formed of the toner. When the thin layer comes to a position opposed to a photosensitive body 21, the toner is made to fly with the DC voltage applied between the carrier 29 and the toner layer to develop a latent image on the drum 21. Since the toner layer is extremely uniformly formed concerning electrostatic condition and layer thickness, the image which is very faithful to the latent image is obtained only with the DC electric field.

CONSTITUTION:A servo sector pulse is inputted to a timing circuit 17 through a sensor 10 and an amplifier 11, and servo signals on servo sectors 7b of disc surfaces 4a and 4b are detected alternately by heads 1 and 2 through a head switching signal sent from a head selecting circuit 12 from the circuit 17, and these servo signals are sent to a position signal detecting circuit 15 through a preamplifier and a low pass filter. The circuit 15 fetches in the servo signal from the circuit 17 in accordance with a timing signal and obtains its magnitude and sends it to a control part 22 through an AD converting circuit 16. The control part 22 obtains the difference between servo signals as a position error signal, and an actuator 6 is controlled through a DA converter 20 and an actuator control circuit 21 so that this error signal is zero.

The output of S4 is inputted to a digital filter F4 with low- pass characteristics whose delay time per delay element is 1/f02<-3>sec so as to erase even-numbered pass bands. The output of F4 is added by an adding circuit D4 to the output of a digital filter S3 with band-pass characteristics whose delay time per delay element is 1/f02<-3>sec. Similarly, the same process is repeated to obtain an output having target characteristics form a final digital filter F0.

IPC: A61B8/00
Filed: 1989-01-24
Abstract: PURPOSE:To suppress the influence of a grating lobe without narrowing view width and to execute a B mode and a D mode by oblique linear scanning by interposing a switching means to change over the coupling of plural oscillators in a channel and a fixing delay means. CONSTITUTION:A reception delay circuit 150 gives reception delay to a received signal corresponding to the B mode, D mode and focus condition obtained from a preamplifier 130. When the B mode and D mode are executed by the linear scanning, the respective channels of an ultrasonic probe 100 are composed of two oscillators 100a, and the non-delay and prescribed delay are given to the respective channels by a fixing delay circuit 110. Thus, rectangular ultrasonic beam by the non-delay and oblique ultrasonic beam by the prescribed delay can be transmitted and received without executing beam deflection in a transmission system. Accordingly, a Doppler signal can be obtained by the oblique linear scanning by the oblique ultrasonic beam. Namely, the D mode picture of blood stream to be shown by an arrow 14 can be obtained.

Title: Charging method and charger for secondary battery
Inventor: TAMAI MIKITAKA
IPC: H02J7/02
Filed: 1993-02-01
Abstract: PURPOSE:To charge individual batteries fully without raising the battery voltage abnormally, by controlling the charging adequately on the basis of the detectability of the voltage of individual batteries. CONSTITUTION:The voltage of the connection point of secondary batteries B1 and B2 is outputted from a detecting terminal T3. When a comparator 13 detects it, a switching element 6 is connected to a contact A (first constant voltage charging circuit 4 side). If it is not so, switching element 6 is connected to a contact B (second constant voltage charging circuit 5 side). When a battery pack 1 is charged, the comparator 13 detects that battery voltage is outputted at the detecting terminal 13, and the switching element 6 is connected to A side. Accordingly, the first constant voltage charging circuit 4 charges the secondary batteries B1 and B2, controlling the charging current so that the voltage of the secondary batteries B1 and B2 may not exceed a set voltage respectively. Consequently, it becomes possible to charge the secondary batteries B1 and B2 fully without raising the voltage of the batteries abnormally.

Title: Production of molten metal for chilled casting
Inventor: KAWAI KIYOSHI
IPC: B22D15/00
Filed: 1981-02-03
Abstract: PURPOSE: To obtain molten metal of a stable chilling tendency in a short time by compounding raw material base metal which is beforehand made into white pig iron at a prescribed amt. with respect to the entire raw material.  
     CONSTITUTION: In lieu of foundary pig iron used heretofore, ground metal (white pig iron base metal) of an increased tendency to white pig iron is used. To make white pig iron, the content of Si is reduced or the shape is reduced in thickness to suppress the graphite formation in the structure in the stage of producing an ingot from the raw material base metal. The reduction in the thickness is accomplished by determining the thickness and the degree of white pig iron beforehand with a test piece or the like and selecting these in accordance with purposes. Since it is possible to reduce the amt. of compounding of iron scraps and eventually to reduce the amount of compounding of a recarburizer by compounding the white pig iron base metal by the above-mentioned manner, the sufficient chill depth is obtained simply by holding the molten metal in a short time.

In the parallel luminous flux (a), a luminous flux which reaches other surface than the tightly adhering surface 19 of the total reflecting surface 18 is totally reflected, becomes a parallel luminous flux (b), and is made incident to an optical fiber 2 by a lens 13. A parallel luminous flux (d) passes through an end face 20 of the optical transparent body 17, reaches the tightly adhering surface 19, transmits without being reflected, becomes a parallel luminous flux (e), and it is made incident to the optical fiber 1 by the lens 12. In this way, a loss generated by an optical branch coupler using a dielectric multi-layer film can be eliminated.
