A plurality of reflection type light emitting diode units 10 each of which includes a light emitting diode 2 and a dichroic mirror 3 in a hollow metal holder case 5 having high thermal conductivity so as to face each other are joined to one another through joint members 4 formed of electrical insulating material, thereby constructing the laminate type light emitting diode device 100.
摘要:
A fuel transfer pipe and a cylinder head of an engine in which a fuel injection device is restricted from being separated from each other by a restricting member. A pressing member is interposed between the fuel transfer pipe and the cylinder head to receive a restricting force of the restricting member presses the fuel transfer pipe to a side opposing the cylinder head and presses the fuel injection device to a side of the cylinder head by a reaction force against the restricting force.

The invention provides a novel process for produing .alpha. -keto-carboxylic acid esters that are useful as intermediates for the preparation of pharmaceutical drugs in high yield by oxidizing .alpha. -hydroxycarbocylic acid esters with hypochlorous acid in the presence of nitroxy radical.
摘要:
A passive seat belt system is constructed of a guide rail longitudinally defining a first channel and a second channel, a slider movable along the second channel of the guide rail, a webbing fastened to the slider and movable between an occupant-restraining position and an occupant-releasing position, a drive member for driving the slider, said drive member being received in the first channel of the guide rail, and a spacer provided between the slider and the drive member to prevent the slider from directly contacting an inner wall portion of the second channel, said inner wall portion being on a side closer to the first channel.

In an electrophotographic developing method using a magnetic brush consisting of a mixture of magnetic carrier and an electroscopic toner, development is carried out at a toner concentration (Ct. %) in the mixture, which satisfies the requirement represented by the following formula: ##EQU1## wherein Sc stands for the specific surface area (cm.sup.2 /g) of the carrier, St stands for the specific surface area (cm.sup.2 /g) of the toner, and k is a number of from 0.90 to 1.14.A toner image having a high quality can be obtained according to this method.
摘要:
An automatic locking and releasing arrangement for vehicular seat belt including a guide rail provided with first and second guide passages, a driving cable adapted to slide through the first guide passage, a connector and a cam both fixed to the cable at a predetermined spacing from each other, a slider adapted to slide through the second guide passage and engage the connector and the cam, a seat belt attached to the slider through a buckle, and an anchor device for retaining the slider in a locking seat belt position. A ring-like slide member is fixed to the cable portion positioned between the connector and the cam, the ring-like slide member comprising plurality of slide portions having a sectional shape a little smaller than that of the first guide passage and arranged through a flexible portion formed between adjacent slide portions. The cable is slid through the first guide passage of the guide rail by the slide portions of the ring-like slide member.
摘要:
An outer tube is used to guide a drive member which serves to drive a slider. The outer tube is constructed of a resin-made cylindrical tube main body, two resin-made slip-out preventing portions formed at both ends of the tube main body respectively, and at least one resin-made bracket provided on the tube main body at a point between the slip-out preventing portions. The slip-out preventing portions and bracket are formed as unitary members with the tube main body.
