Title: Manufacture of compound semiconductor wafer
Inventor: YAMAMOTO HIROMASA
IPC: H01L21/205
Filed: 1988-07-20
Abstract: PURPOSE:To eliminate the frequency dependency of C-V characteristics, to lessen a leakage current in an undoped epitaxial layer and moreover, to attain the uniformity of device characteristics by a method wherein a compound semiconductor single crystal brought up is cut in a lamellar form and thereafter, the crystal is performed a heat treatment at a specified temperature and thereafter, the crystal is cooled to a specified temperature range and is performed again a heat treatment at the specified temperature and after that, after the crystal is cooled up to a room temperature, a mirror finish is performed. CONSTITUTION:A compound semiconductor single crystal brought up is cut in a lamellar form and thereafter, after being performed a heat treatment at a temperature of 85% or higher of the melting point of the crystal, the crystal is cooled to a range of 45-70% of the melting point and is performed again a heat treatment and after that, after the crystal is cooled up to a room temperature, a mirror finish is performed. The reason why the temperature range of the first-stage heat treatment is set at the range of 85% or higher of the melting point is for reducing an egg-shaped pit density. The reason why the temperature range of the second-stage heat treatment is limited to the range of 45-70% of the melting point is because the whole wafer is brought into a low-resistance state at a temperature of 45% or lower of the melting point and on the other hand, an effect is not sufficiently obtained at a temperature of 70% or higher of the melting point.

Title: Cassette storage
Inventor: ASHIZAWA NORIKO
IPC: B65D85/86
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To prevent flexure of a lead frame or tape substrate stored in a cassette, by setting between product insertion grooves a flexure prevention plate having a recess retractively formed from its end toward middle. SOLUTION: A storage cassette 3 comprises product insertion grooves 4 formed in a pair of opposite sides, and flexure prevention plates 1 set between the product insertion grooves 4. In each of the flexure prevention plates 1, a recess is formed from its end toward middle so that when a lead frame or tape substrate 5 is inserted in the product insertion groove 4, flexure is corrected in the direction of the insertion. The flexure prevention plate 1 having a recess formed in the middle of the end in the direction of the product insertion has a curved line 2 as a trumpet has. The middle of the lead frame or tape substrate 5, as a product, has large flexure. As the product is stored further inside, a point at which the flexure prevention plate 1 supports the lead frame or tape substrate 5, as the product, gradually moves inwards and, thus, the flexure is gradually decreased.

Title: Fuel gauge with residual quantity alarming function
Inventor: OISHI MANABU
IPC: G08B21/00
Filed: 1993-07-26
Abstract: PURPOSE:To improve the reliability of a measuring instrument without losing the function for displaying or alarming fuel residual quantity by providing a resistor having a first resistor to which a contact is slid according to a level change in a fuel vessel to cause a resistance change; a gauge for displaying the residual quantity of the fuel; and an alarm circuit for alarming the residual quantity. CONSTITUTION:The display of residual quantity is conducted on the basis of the resistance change by sliding a contact 7 to a first resistor 2'. On the F side from a residual quantity alarming point P, no current is carried to an alarming circuit 14 by a transistor 15 and a second resistor 19, and an alarm lamp 9 is not lighted. Over the residual quantity alarming point P, the alarming circuit 14 is earthed by the sliding contact by the operation of the transistor 15, and the current is carried to light the alarm lamp 9. Since the resistor to which the contact is slid is not insulated in the residual quantity alarming point P, and the resistance is continued, the current is linearly changed to the residual quantity, never causing a sharp current rise nor a skipping phenomenon of gauge. Since the alarming point P has no insulating part, no migration occur, and an insulating failure by penetration of water is also never caused.
