Title: Method for controlling facsimile equipment
Inventor: KATSURAGI SHIGERU
IPC: H04N1/17
Filed: 1991-03-20
Abstract: PURPOSE:To save the trouble in operation at transmission time by automatically setting the reading resolution of transmitted original. CONSTITUTION:Before the transmission of picture information, a scanner 4 reads the leading part picture of the transmitted original at high resolution it in a system memory 2. A control part 1 decides the optimum reading linear density of the transmitted original based on the contents of this picture signal. The linear density of the transmitted picture is decided from the receivable picture linear density notified from the opposite party and a decision linear density. When the decided linear density is high resolution, the stored leading picture signal is encoded and compressed by an encoding/decoding part 7, and transmitted through a G3 FAX MODEM 9. Then, the remaining picture is read with high-resolution linear density and transmitted after encoding compression. On the other hand, the decided linear density is standard resolution, the picture signal of the leading part is converted into the picture signal with the standard resolution, and transmitted after encoding compression. Then, the remaining picture is read by the linear density with the standard resolution, and thus obtained picture is transmitted.

Title: Switching power supply circuit
Inventor: SUGIURA KAZUNARI
IPC: H02M1/08
Filed: 1995-04-05
Abstract: PURPOSE: To surely raise the output of a switching power supply without delaying the rise time of the power supply when the power supply starts by always outputting a switching pulse having a short pulse width from a pulse control circuit while the output of the power supply does not rise after the power source starts power supply. CONSTITUTION: While the output voltage of an output terminal 15 does not reach a desired voltage, a starter circuit 13 outputs a certain logical output (e.g. a high level) and, when the output voltage of the terminal 15 reaches the desired voltage, the circuit 13 outputs an opposite logical output (e.g. a low level). Therefore, a pulse control circuit 11 always controls the pulse inputted to the gate of a switching transistor 7 to have a short pulse width regardless of the output of an error amplifier 12 until the output voltage of the terminal 15 reaches the desired voltage.

Title: Manufacture of outer wheel for ball joint
Inventor: SAKURAI HISASHI
IPC: B21K1/76
Filed: 1986-04-08
Abstract: PURPOSE:To improve the finishing accuracy of a product by performing the ironing of the outer wheel for joint with bearing the outer peripheral part of the bottom face of a preform on the end face of each forming die of a punch. CONSTITUTION:The outer peripheral part of the bottom face 13 is borne on the upper end face 30 of a forming die 18 by holding each forming die 18 at the ironing position and by covering a preform 11 on the outer part. In this case, a rough formed ball rolling groove 8 and retainer sliding face 9 are fitted with each projecting face 31, 32. The retainer sliding face 9 and rolling groove 8 are subjected to a plastic deformation so as to profile the projecting faces 31, 32 by biting a work part 40 into the peripheral wall of the preform 11 with the descent of a die 16. In this case, the pressure toward the slant rear part from the working direction front part is acted on the forming die 18, but the movement of the forming die 18 can be prevented because of the outer peripheral part on the bottom face of the preform 11 being pressed to the upper end face 30 of the die 18.

Title: Chain conveyor
Inventor: HORII TAICHI
IPC: B65G17/48
Filed: 1988-04-01
Abstract: PURPOSE: To ensure the discharge of articles by disposing engaging mechanisms for putting the transporting plane of slat-like transporting bodies to a pendent posture nearly perpendicular behind a conveyor chain together with the slat-like transporting bodies on holders. CONSTITUTION: A prescribed number of the slat-like transporting bodies 16 meeting the sizes of chain ring pitches are pivoted to the respective holders 15. If the chain ring pitches are large, the pivoting of, for example, three pieces of the slat-like transporting bodies 16 is made possible to reduce the width in the progressing direction of the slat-like transporting bodies 16. There is, therefore, no need for supplying the articles 10 at relatively large spaced intervals so as not to place the articles 10 more than one piece for each one piece of the slat-like transporting bodies 16 at the time of supplying the articles 10 onto the conveyor chain 1. The random supply of the articles at nearly irregular intervals is thus possible.

IPC: G11B27/10
Filed: 1981-05-29
Abstract: PURPOSE:To decrease the readout time, by starting read from a track where the alignment of tracks is finished, in reading data from two disc driving devices storing the same content. CONSTITUTION:Disc driving devices 7 and 8 are taken as a pair for double write, and once one address A is given to them, they have the same content at all times and function as if they were one set of disc driving device. A disc controller 4 includes a disc controller processor 12 and a command storage area 11.

Title: Fuel cell
Inventor: YAMAZAKI YOSHIO
IPC: H01M8/08
Filed: 1981-05-28
Abstract: PURPOSE:To maintain the active state of an electrode and substantially increase reliability for a long period of time by forming the film of a high molecular bonding substance with octacyano-metal complex on a carbon electrode in a fuel dissolving type fuel cell using methanol/air or hydrazine/air as a fuel. CONSTITUTION:Polyvinyl pyridine bonding film 3 with octacyanomolybdenum is formed on the surface of an air electrode acting as a cathode, and it acts as a catalyst to increase reactivity and a separator between an anolyte and air. By reacting a complex with a high molecular substance having a lyophilic hydrogen ion group, the resulting substance acts as a separator having a property which makes proton (H<+>) or hydroniumion (H3O<+>) permeable but does not make water molecule permeable between the anolyte and air. Therefore, the wettability of the air electrode can be prevented and the life of a battery is substantially increased.

Then the processing circuit from the detecting means D1 to the 1st analog comparing circuit 4 detects the presence of the human from variation in mean brightness and the 2nd analog comparing circuit 5 judges the ambient brightness from the output of the 1st amplifier 2. Thus, the ambient brightness and the presence of the human are detected at the same time. Consequently, the operation is secured by the simple constitution and the low-cost room presence sensor is obtained.

Abstract: PURPOSE:To suppress parasitic resistance in a PMOS semiconductor element and to make it possible to implement super-minute semiconductor device, by providing a side wall only for the gate electrode of an NMOS semiconductor element. CONSTITUTION:In a CMOS semiconductor device 59 having an NMOS semiconductor element 49 and a PMOS semiconductor element 57, a side wall 31b is provided only for a gate electrode 23b of the NMOS semiconductor element 49. Namely, after an N<+>-region forming resist pattern 53 is formed on a PMOS forming region 13, anisotropic etching is performed for an NMOS forming region 17 of a deposited layer 29 by an RIE method or other arbitrary suitable methods. The side wall 31b is formed around the gate electrode 23b on the side of the NMOS semiconductor element. The side wall is not arranged for the PMOS semiconductor element 57, which constitutes the CMOS semiconductor device 59. Therefore, p-type impurities, which are implanted in the vicinity of the channel part of the PMOS semiconductor element, are diffused into an oxide film or into the side wall 31b. Thus the parasitic resistance, which is yielded in said channel part, can be suppressed.
