A method of die bonding electronic components. A wafer is mounted on a dicing tape (17) comprising at least one layer of shrink film and a pressure sensitive adhesive layer so that the wafer is stuck thereto by the pressure sensitive adhesive layer. The wafer is then diced so that the wafer is cut apart into a multiplicity of chips (16). The dicing tape (17) having the multiplicity of chips stuck thereto is placed on a table equipped with heating means. This is followed by shrinking the shrink film forming part of the dicing tape by the heating means (3, 7) so that an area of adhesion and adhesive strength between the chips and the adhesive layer are decreased and so that the chips are arranged with predetermined spacings. The final step is suctioning the chips (16) arranged with predetermined spacings one at a time by a suction collet (19) disposed above the chips so that the chips are separated from each other. This method enables effective die bonding without damaging the chips. Apparatus for effecting the method is also provided.

To dispense optical fiber, electrical wire, or the like between two desired points, a line dispenser and dispensing method for dispensing a line preliminarily housed inside to the outside of the line dispenser is provided. Particularly, the line dispenser is characterized by provision of a guide member, which is provided between a body portion of a reel and an aperture for dispensing the line to the outside of the line dispenser and which is rotatable about the center axis of the reel. This rotatable guide member enables smooth dispensing of the line.

A method for manufacturing a golf club head, which enables a face to be formed thinner to realize a more free distribution of weight. A flat surface 1A of a head body 1 is formed with plural cavities 6 to strengthen a face 4. Thus, the face 4 can be made thinner, which enables the distributing of thus obtained surplus weight to other parts of the head body 1. Each cavity 6 is disposed opposite to an area 9A between adjacent score lines 5. Accordingly, sufficient thicknes A of the face 4 can be guaranteed to prevent the degradating of strength caused by forming the thinner face 4.

An iron or putter golf club head having a larger sweet area and the lower center of gravity. Weights 12a and 13a of beryllium copper alloy are provided along peripheral portions of a head body 11a of titanium alloy at its face 1a and back 2a side respectively. Specifically, the back weight 13a has a weight-sole portion 20a integrally extending down to a sole 3a. The weight-sole portion 20a is widened at its toe and heel sides relative to its intermediate portion. Thus, the weight distribution of the head is capable of being greatly concenterated on the peripheral portion of the head to enlarge a sweet area. In addition, owing to the weight-sole portion 20a, the center of gravity can be effectively lowered.

An air conditioner including an outdoor unit containing a compressor and an outdoor heat exchanger therein, at least one indoor unit having both of an indoor heat exchanger and an electric expansion valve, and a pressure reducing member which is linked to the electric expansion valve in parallel in a refrigerant circuit and serves as resistance to refrigerant flowing therethrough. The valve opening degree of the electric expansion valve of the indoor unit when a room heating operation is stopped is set to be smaller than the valve opening degree of the electric expansion valve of the indoor unit when the room heating operation is conducted, and the resistance value of the pressure reducing member is set to be smaller than the resistance value to be provided to the refrigerant in accordance with the valve opening degree of the electric expansion valve when the room heating operation is stopped.

A set of iron golf club heads for correction of each tendency to hook balls for short irons, and to slice balls for long irons respectively. As the number of the iron golf club head increases, the back of each head body is shifted crosswise away from the neck relative to the face. Thus, as the number of the iron golf club head increases, the center of gravity of each head body is generally shifted crosswise away from the neck as well. Particularly, a position of a middle point M of the face of the 5th iron golf club head is approximately consistent with that of the center of gravity with respect to the lateral direction. Owing to the above position-settings of the center of gravity, balls are given slicing rotation for short irons, while balls are given hooking rotation for long irons, thereby decreasing either a habitual hooking or slicing tendency.

A current collecting apparatus provided with sliders 2 for collecting electric power from a power feeder 1, a current collector 3 for collecting power, an insulator for insulating and supporting the current collector 3, and a flexible conductor for delivering the power collected by the current collector 3 to a conductor 5, which is connected to the flexible conductor and used for supplying the power to the vehicle side. The conductor 5 and the insulator 4 are disposed so that the former is offset with respect to the latter in the crosswise direction of a railway vehicle. With this arrangement, aerodynamic noise emanating from the current collector loaded on the vehicle running at high speed can be substantially reduced.
