Title: Recording device and method therefor, and facsimile equipment
Inventor: YAKABU YASUHIRO
IPC: G03G15/08
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To perform more accurately control of recording material by making a residual amount of the recording material possible to be determined in accordance with contents of a recorded image. SOLUTION: The sequence controlling section 141 is, allowed to decide whether a residual amount of toner in the toner cartridge 15 becoming below the specific value or not, based on a signal from a magnetic sensor 16, and to set the signal NOTNR on 1 when becoming below the specific value. A main controller is allowed to control the residual toner amount in response to the signal NOTNR becoming to 1. Accordingly, a black ratio measuring section 112 is allowed to count black picture elements of the image data to be recorded, and to make same as the used quantity of the recording material adopted for recording the image data. Then, the new residual quantity of toner is defined by deducting the black picture elements counted by the above black ratio measuring section 112, from the picture elements showing the current residual toner amount.  In such a manner, when the updated residual toner becomes below the picture elements for one page portion, the recording from the next page is inhibited.

Title: Analog-to-digital converting circuit utilizing standard current of high-order bit
Inventor: IGARASHI MAKOTO
IPC: H03M1/38
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To obtain a high-precision digital output by comparing the total of standard currents of all high-order bits whose digital output which is already determined is 1 and standard currents corresponding to the bits of a digital output to be determined with an analog input. SOLUTION: When the most significant digit bit is 1, a PFET: 17 turns on for a next high-order bit and the standard current of the most significant bit is subtracted from the input current supplied from a PFET: 12. The standard current of the high-order 2nd bit is supplied from a standard current source 23 so as to subtract the standard current of the high-order 2nd bit from the current which is thus processed. The digital output of the 2nd bit is 1 when the input of an inverter 15 is at a high potential. Standard currents from (n-1) standard current sources controlled corresponding to the digital output of (n-1) high-order bits and the standard current of an (n)th bit are subtracted from the input current to determine the digital output of the (n)th bit.

IPC: C23F4/00
Filed: 1990-11-01
Abstract: PURPOSE:To increase a uniformity of the velocity distribution of etching for having no bad electric effect on a substrate by making a gradient in a magnetic field intensity in the drift direction of electrons in a plasma. CONSTITUTION:A cathode electrode 3 is connected to an RF power 5. A permanent magnet 10 being located aslant behind an anode electrode 2 so that it may make an acute angle with the anode electrode, a gradient is made in the intensity of a magnetic field, which is generated by the permanent magnet 10, in the drift direction of electrons in a plasma. Since a high-density plasma is formed under the influence of a magnetic field which is generated by the permanent magnet 10 in a space between the anode electrode 2 and cathode electrode 3 and a gradient is made by the permanent magnet 10 in a magnetic field intensity in the drift direction of electrons, a plasma density in the drift direction is not increased extremely. Consequently, such an apparatus is obtained that the etching speed may be fast, a uniformity of the velocity distribution of etching may be good, and an etched substrate may have no bad electric effect.

Title: Die for forming decorative inmold
Inventor: TAKATSUKA KORO
IPC: B29C45/14
Filed: 1994-11-30
Abstract: PURPOSE: To improve the productivity of a surface flawless, high quality plastic decorative molding by making a bottom force of a die compact. CONSTITUTION: A pealing layer 2 for blocking an air hole is formed by applying a vinyl chloride resin to the outer peripheral surface of a bottom force of a die 1 formed of an air-permeable material, and a film F for inmold decoration is pressed against the outer peripheral end surface of a cavity 1a in the die 1 using a top force 4 through a sealing member 3. At the same time, the die 1 is supported by a receiving member 5 with a suction function on the suction side through a sealing member 6. Thus the die 1 no longer need be engaged with a main bottom force system for preventing an air from penetrating from outside. Consequently, it is possible to make the bottom force compact, and the film F can be adsorbed and attached firmly to the inner surface of the cavity 1a in a short time because of the superb sealing properties of the die 1.  Therefore, it is possible to form a high quality molding free from a flaw on the surface at high efficiency.

Title: Casting method of aluminum castings
Inventor: SHINYA NOBUAKI
IPC: B22D19/00
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To obtain a casting without casting defects by enveloped casting a different kind metallic member with aluminum, after the primary preheating is carried out while an inner flame part of reducing flame is touched to the different kind metallic member and the secondary preheating is further carried out while an outer flame part of the neutral flame are touched directly or indirectly. SOLUTION: A gas burner 2 is arranged in a way that an inner flame part of the reduction flame touches a different kind metallic member 1 so as to carry out the primary preheating. Then, the flame is adjusted to be neutral flame so as to carry out the secondary preheating while an outer flame part of the neutral flame touches the member. At that time, while the flame is touched to a stand at a center part of the different kind metallic member 1, the flame is reflected from the stand to touch the different kind metallic member 1 so as to indirectly carry out the secondary preheating, resulting in the temperature rising with the temperature of each part even. Furthermore, a spacer 3 is arranged between the stand and the different kind metallic member 1, and the secondary preheating is carried out by rising the bottom of the different kind metallic member 1.  Thus, the flame comes to spread outward and the preheating is effectively carried out. The preheated different kind metallic member 1 is arranged at a given position of a mold, and is enveloped-cast by pouring the Al alloy so as to carry out casting inexpensively.
