Abstract: PURPOSE:To allow the title system to rapidly correspond to the generation of misreading or miswriting by providing a head with plural reading/writing areas so that reading and writing operation can be executed in any area. CONSTITUTION:The head 7 has plural reading/writing(R/W) areas A-C and is constituted so that R/W operation can be executed in any area by moving a data carrier 9 so as to successively cross these areas A-C.

IPC: H01S5/00
Filed: 1991-04-22
Abstract: PURPOSE:To smoothly perform the cleavage operation of a semiconductor substrate and, at the same time, to satisfactorily dissipate heat from a laser-beam radiating edge by a method wherein an electrode metal layer which has been formed on the whole surface on the side of an active layer for a laser diode chip is made to lack excluding a laser-beam radiating part on the side of the laser-beam radiating edge. CONSTITUTION:An electrode metal layer 13 which has been formed on the whole surface on the side of an active layer for a laser diode chip 10 is made to lack excluding laser radiating parts 17, 17 on the side of laser-beam radiating edges; metalelectrode lacking parts 16 are formed. In the case of an ordinary double heterojunction stripe laser, as the semiconductor laser diode, whose resonator length is at 600mum, whose chip width is at 300mum and whose optical output is at 100mW, the metal electrode layer 13 is left in the laser radiating parts 16, 16. Thereby, it is possible to restrain a temperature form being raised at laser-beam radiating edges. When their residual width is at 20mum, it is possible to obtain a result which is hardly inferior to that of a case where the electrode metal layer 13 is formed on the whole surface of the chip. Even when their residual width is at 5mum, an effect to restrain a temperature rise is large.

Filed: 1978-07-25
Abstract: PURPOSE: To ensure the normal operation for the amplifier even when the power voltage lowers down by varying the bias voltage of the input terminal nonlinearly to the power voltage.  
     CONSTITUTION: The amplifier consisting of element 10∼29 features the similar constitution to the conventional one. And power voltage VS is supplied to terminal 4, and terminal 6 is connected to load RL as well as fed negatively back to element 12. Element 11 to receive the input signal from terminal 2 is biased by the circuit comprising resistances 8, 9 and 34 plus diodes 30∼33. This bias voltage turns to the divided voltage value of resistance 8 and 9 in case VS is higher than a certain prescribed level. And in case VS is lower then the prescribed level, the bias voltage features the value obtained by dividing the voltage obtained by subtracting the forward voltage of diode 30 and 31 from VS via resistances 8, 9 and 34 each. If resistances 8, 9 and 31 are set properly, the output signal can be controlled symmetrically up and down even though the power voltage may lower down.

Title: Inspecting method of semiconductor substrate surface
Inventor: KURODA IWAO
IPC: H01L21/66
Filed: 1978-07-25
Abstract: PURPOSE: To objectively and accurately inspect a semiconductor substrate surface by measuring the reflecting factor of light on the substrate surface using a spectrophotometer.  
     CONSTITUTION: A spectrophotometer is so adjusted that the light reflection factor becomes 100% when mirror fisished semiconductor substrates are placed on the standard sepecimen rack and article specimen rach of double luminous flux spectrophotometer. When a chemical polishing finished substrate is placed on the article specimen rack, the reflection factor of the light is measured. The mirror finished substrate surface is optically substantially flat, while the chemically polishing finished substrate surface is optically rugged to thereby cause the surface to scatter the light with the result that the apparent light reflection factor thereof becomes lower than that on the mirror finished substrate surface. The light reflection factor on the chemically polishing finished substrate surface thus obtained exhibits preferable correlation with the glossiness of the gloss sample sorted visually. Thus, it can inspect objectively and accurately as compared with the visual inspection.

Abstract: PURPOSE:To improve water quality by increasing the occupation ratio of small groups of water molecules by activating the movement of groups of water molecules by installing ceramic solids movable in a water channel as a purifying means installed in the water channel having a water supply opening and a water discharge opening. CONSTITUTION:When water introduced from a water supply opening 17a is sent along the tangential line of a ring-shaped channel 16 through an exhaust nozzle 18, a circumferential water flow S is generated in the channel 16. More than one spherical solid 20 of ceramic which radiates extreme infrared radiation is installed in the channel 16. Since each spherical solid 20 rotates and revolves irregularly by the water flow S, the movement of groups of water molecules is much more activated so that the occupation ratio of small groups of water molecules increases. Water is purified and improved of its quality as it passes through a channel 19, enters a case 3 from inlet 9, and passes through the layers of ceramic 12, active carbon 13, ceramic 14, and coral sand 15 one after another, and is discharged from a discharge opening 8a.
