Abstract: Disclosed is a golf club having a structure with which optional angle adjustment can be easily and firmly performed by a user himself/herself without changing the direction of a shaft along the circumference thereof with respect to a head. To this end, the distal end portion of the shaft to which a plug member is fixed is fitted into a shaft insertion hole of a hosel portion from above, an angle adjusting member is fitted from below, and a fixing bolt is fitted into a bolt insertion hole of the angle adjusting member and screwed into an internal thread portion of the plug member.

Abstract: An object is to effectively cool down an electronic equipment which is face with height limitations and tends to readily increase in heat generation amount to thereby provide the reliability required. The interior of a chassis of a control unit is partitioned by a back board into a front side space and a rear side space. In the rear side space, two control modules are attached so that these are stacked up and down, while two fan modules and a single duct member are attached in the front side space. Each fan module has two fans as built therein. A cooling air stream or “wind” from each fan flows into the lower-side control module through the duct member and others, whereas a cooling wind from the other fan flows into the upper-side control module. Even when either one of the fan modules goes down during operation, it is still possible by using the remaining fan module to cool down the both control modules.

Abstract: As a novel photochemotherapeutical method for the treatment or prevention of an auto-immune disease, there is provided a method for treating an auto-immune disease, which comprises administering to the patient mono-L-aspartyl chlorin e6 or mono-L-glutamyl chlorin e6 or a pharmacologically acceptable salt thereof, followed by subjecting the blood vessel blood of the patient containing the administered compound to exposure with an ultraviolet ray or a laser light, thereby to excite said compound photochemically. This method is effective to decrease the level of auto-antibody in the blood of the patient and is also of high safety.

Abstract: Denim cotton warp yarns are rope-dyed with a benzoquinone dye of formula (I): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.1 ', R.sub.2 ' and R.sub.3 ' commonly or independently represent a hydrogen atom, a halogen atom, alkyl, cycloalkyl, alkenyl, aryl, aralkyl, alkoxyl or alkoxyalkyl alone or in combination with a red .DELTA..sup.2,3' -biindolin-3,2'-dione dye and/or a blue indigoid dye or sequentially with the latter dye.

Abstract: Disclosed is a dyeing process for rope dyeing denim cotton yarns a fashion blue color which comprises the steps of forming the yarns into a rope; repeatedly immersing the rope in a dye bath containing a reduced water soluble form of a halogenated indigo derivative which is air oxidizable, squeezing the rope to remove dye bath liquid therefrom exposing the damp rope air to air oxidize the reduced form of the indigo derivative in the yarn; and then further oxidizing the incompletely oxidized reduced form of the indigo derivative in the yarn forming the rope in an oxidizing bath containing a chemical oxidant, e.g., sodium perborate.

Abstract: Dyed denim cotton yarns capable of meeting the market demand for color jeans can be provided by immersing denim cotton yarns in a dye bath containing a dye or dye composition comprising a specific indirubin derivative(s), a specific quinophthalone derivative(s) and/or an indigo dye, squeezing and air-oxidizing the dyed yarns, and repeating a series of these steps.
