IPC: H04L1/00
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of communication error by controlling transit to a control channel based on number of frames received correctly at the reception of a primary channel in the same block. SOLUTION: This equipment is provided with a function of receiving primary channel information and a function of receiving control channel information based on the ITU-T recommendations V.34, and when frames without error cannot continuously be detected during reception of the primary channel information for a prescribed time, the function of receiving the control channel information is selected. A control circuit 20 conducts control of decreasing shorter the prescribed time when number of frames correctly received at the reception of primary channel information in a same block in comparison with the case that number of the frames correctly received is less.  Thus, the control with respect to a weaker error and the control with respect to a stronger error are properly executed and facsimile communication with an excellent efficiency placing priority over a communication time is realized.

Abstract: PURPOSE:To determine a personal feature automatically by digitizing a picture image of the face of a person to be determined, and determining with which feature type among the plural feature types registered previously in a control part the image is matched by means of a neural network. CONSTITUTION:A person to be determined is stood on a photographing stage 14 and his face is photographed by a camera 15 so as to be displayed on a screen of a TV monitor 16 as a digitized contrast gradation picture image and also to be taken into a control part, 12. In the control part 12, one part of a face in the width direction is divided so as to find horizontal histogram inside a partition on the basis of the predetermined characteristic part of the face, and the face characteristic parts such as bows, eyes, nose, and mouth are recognized from the difference in gradation, while the size between the respective parts of the recognized face or the size from each of the parts to the predetermined position of the face are measured, and consequently it is determined which feature type among plural feature types, which are registered previously in the control part, 12 as teacher data, matches with the face by means of a neural network. In this way, it can be determined automatically which feature type matches the face of the person to be determined without depending on any artificial determination.

Title: Sucker suction releasing device
Inventor: NAKAJIMA HAJIME
IPC: G03B42/02
Filed: 1994-11-11
Abstract: PURPOSE: To provide a sucker suction releasing device of simple structure and which is compact and economical for releasing suction of a sheet by forming a gap in a contact part with the sheet and a sucker by deforming the sucker sucked the sheet and allowing air to flow from the gap. CONSTITUTION: When a sucker holding plate 31 comes lower and a sucker 32 is brought into contact with a sheet S, the sucker 32 is pressed and air inside it is discharged. Simultaneously, the contact of the sheet S is detected and the sucker holding plate 31 starts to go up. Whereby, pressure of the sucker 32 is released and the air in the sucker 32 is expanded by restoring force of the sucker 32 and negative pressure is generated, so that the sheet S is sucked. A lever 33 moves rotationally around a support 33a and a projected part 33b of the lever 33 lifts up an edge part 32a of the sucker 32 to deform the sucker 32. Whereby, a gap is formed in a contact part with the sheet S and the sucker 32 and air flows in from this gap, so that suction of the sheet S is released.

Title: Head supporting mechanism
Inventor: IKENAGA AKISHIGE
IPC: G11B17/32
Filed: 1986-12-19
Abstract: PURPOSE:To scarcely generate an output drop caused by the increase of a gap between a head and a magnetic disk, by constituting the titled mechanism so that the rotary axis of a gimbal spring is shifted and positioned while deviating to the upper side in the rotational direction of the magnetic disk from the center surface of the head. CONSTITUTION:The rotary axis B of a gimbal spring is positioned at the upper side in the rotational direction C from the center surface A of a head 2. When a magnetic disk 3 rotated, the head 2 rotates centering around the rotary axis B of the gimbal spring 1 by a dynamic pressure effect by an air flow D, and a gap in the gap position P of the head 2 becomes h0+DELTAh2, but since the rotary axis B is shifted and positioned at the upstream side from the center surface A, the head 2 is scarcely pushed up, and DELTAh2 becomes smaller than DELTAh1. DELTAh1>>h2. In such a way, the increase of a gap between the magnetic disk and the head in a gap position by the rotation of the magnetic disk is suppressed, and high density recording can be executed.

Abstract: PROBLEM TO BE SOLVED: To reduce the size and weight of a vehicle AC generator by a method wherein the constructions of a collector and a brush device are simplified. SOLUTION: In a generator, a negative pole side slip ring 42 is pushed into a center hole 37 formed in the rear end surface of a shaft 5. A rivet 55 is driven into the bottom surface of a bottom wall 20 of which the bearing housing 18 of a rear housing 12 is composed to fix a negative pole side brush 52 directly to the rear housing 12 in order to make the negative pole side brush 52 slide along the axial direction end surface of the negative pole side slip ring 42. The negative pole side slip ring 42 is made of conductive copper alloy and the negative pole side brush 52 is made of phosphorus bronze or berillium copper which is copper alloy spring material and formed by a press. With this constitution, the thickness of the negative side brush 52 can be reduced and, further, the axial length of the shaft 5 can be reduced significantly.  Moreover, as the negative pole side brush 51 is not only used as a conventional spring but also as a pigtail, a current can flow through the negative pole side brush 51 easily, so that a vehicle AC generator 1 which produces little power loss can be realized.

Abstract: PURPOSE:To improve the adhering strength of a soldered section by forming pectinated toothlike cutout protrusions at the ends of a substrate corresponding to lands, and disposing the lands inside from the edge of the substrate, thereby adhering the film of the protrusions to a printed substrate. CONSTITUTION:In order to adhere a substrate 1a to a printed substrate 4, the cutouts 1c of the substrate 1a are first aligned to the lands 5 of the substrate 4, thereby determining adhering positions. Then, the film 3 of the substrate 1a is adhered with an adhesive 7 to the substrate 4. Thereafter, the lands 2 of the substrate 1a are soldered to the lands 5 of the substrate. In this case, since cutout protrusions 1f protrude in length (n) of 1/2 or more of the soldering length (m), the adhering strength of the film 3 to the substrate 4 becomes a large reinforcing force to fix the soldered section 6 and particularly the adhered section 6a to the substrate 4. Both the lands 2, 5 can be easily positioned by the cutouts 1c of the substrate 1a, the adhering strength of the soldered section 6 becomes very large, and the solder becomes to scarcely flow.
