Abstract: In the metal iron golf club head (1), the rigidity of the medium sensitivity region (5) which is a region on the heel side and excluding the vicinity of the face center (3) is made lower than the rigidity of the low sensitivity region (4) so as to approximate the natural frequency of the metal iron golf club head to the natural frequency of the ball as well as to ensure the strength in the face portion (2).

Abstract: A brake hydraulic pressure circuit for increasing the speed of pressure increase at the wheel cylinder by the simple hydraulic circuit. An accumulator is connected to the discharging side of the pump of the hydraulic return circuit via a first switching valve. A hydraulic supplying circuit, branching from the line between the first switching valve and the accumulator, is connected to the suction side of the pump of the hydraulic returning circuit via a second switching valve. Brake fluid reserved in the accumulator is then supplied to the main hydraulic circuit and is supplied to the suction side of the pump via the hydraulic supply circuit.

Abstract: An apparatus includes an insulated first switching element and a capacitor which are connected in series between one of positive and negative main circuit wirings connected to an ungrounded power source and a ground potential section (vehicle body); a second switching element with one terminal thereof connected to a junction point of the first switching element and the capacitor; switching element control device for selectively closing the first switching element for a predetermined time so as to charge the capacitor and for closing the second switching element so as to discharge the capacitor while the first switching element is opened; device for detecting the electric charge accumulated in the capacitor; and device for determining the insulation between the other of main circuit wirings and the ground potential section in accordance with the detected amount of charge.

Abstract: A vehicle brake control device is provided which effectively reduces the noise and pulsation, while securing a pressure boost during anti-skid control and traction control. The brake control device is comprised of a main brake line routed through the master cylinder 13, inlet valve 25, and the wheel cylinder 26, wherein an accumulator 24 to store the hydraulic pressure is installed in the brake line between the master cylinder 13 and wheel cylinder 26.

Abstract: An anti-skid control device is provided that eliminates noise and vibration, provides better pedal responsiveness, and provides better anti-skid control. In the anti-skid control device 1, a pressure regulator valve 4 is positioned in the brake line between the master cylinder 12 and inlet valve 21, and the pressure differential between the input side and output side of the inlet valve 21 is minimized.

Abstract: An apparatus for controlling the degree of fiber variations in paper sheet has a formation meter for receiving an image of transmitted light on one side of an area of paper from a light source located on the other side of the area of paper, an image processing computing element for introducing the image from said formation meter for image processing and a fuzzy control unit for calculating and outputting optimum J/W ratio, optimum foil angle, and optimum deflector pushing degree and angle on the basis of results of image processing from said image processing computing element.

Abstract: A bundle-of-electric wire container can contain a bundle of electric wire P wound in a loop shape and permit drawing out of the electric wire. Containers can be stacked in a plurality of stages to increase storage efficiency and conveyance efficiency. A bundle-of-electric wire containing space is formed between core pieces and an outer cylinder, and the bundle of electric wire is protected by the outer cylinder. The container is used as one unit for the storage of a bundle of electric wire and to the feeding of the electric wire P through a conveyance. Accordingly, in the manufacturing field of a wiring harness, the bundle of electric wire can be stored and conveyed without losing its shape, for example, and done so efficiently. It is possible to improve the operating efficiency of a manufacturing line by preventing the electric wire from being tangled, for example, at the time of feeding the electric wire as well as to prevent an inferior product from being manufactured.

Abstract: A number of embodiments of suspension systems for vehicles having at least two and, in all illustrated embodiments, four wheels, each of which is independently suspended by a respective shock absorber. The shock absorbers are generally conventional in nature but are interconnected by a system that includes an accumulator and a flow control so as to provide a damping for vehicle characteristics that is independent of the individual damping of each wheel's shock absorber. A wide variety of accumulator structures and flow controls for achieving these purposes are disclosed, as are a number of ways in which various wheels of the vehicle can have their shock absorbers interconnected.

Abstract: A formation control method and apparatus in which an image is emitted from a light source and transmitted through a predetermined area of paper an captured by a camera to be displayed as transmitted light image on a display of an image processing computing element, the transmitted light image displayed on the display being image-analyzed to obtain formation factor for quantification of the formation, J/W ratio and the like being optimized by fuzzy control using membership functions based on said formation factor so as to improve the formation.
