Title: Pickup controller
Inventor: OONISHI JIYUNICHI
IPC: G11B3/10
Filed: 1982-12-14
Abstract: PURPOSE:To prevent sufficiently the resonance of a pcikup arm by processing the 1st and the 2nd output voltages and compensating their variations with time due to temperature fluctuations, and holding a pickup and a record disk in invariably constant position relation according to the temperature-compensated outputs. CONSTITUTION:The time when a sound passes through a route (x) in a figure is denoted as Tx, and the sound velocity increases by (k) times. When it is reflected by the record disk 4, namely, when the sound passes through a route (y), the time is denoted as Ty. Output voltages Vx and Vy are proportional to the times Tx and Ty, so a division output Vz is (b+kc)/a and depends upon values (a), (b), (c), and (k) regardless of ambient temperature. The values (a) and (k) are determined by the material and the thickness of a head shell 8 is always constant, and the value (b) is regarded almost as constant. The value (c) is nearly proportional to the height H of the head shell, so the characteristics of the division output Vz to the height H do not depend upon the temperature. This division output Vz is shifted in level by a level shifting circuit 21 to obtain an obtain an output voltage VH.

Title: Unsealing-preventing seal, and circuit case
Inventor: ASAMI TADAO
IPC: B65D25/20
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To enhance the reliability of a function for restraining unsealing by certainly leaving the mark of peeling in the case in which an unsealing preventing seal is peeled after it was stuck to a body to be stuck. SOLUTION: This unsealing preventing seal 56 is constituted by forming a cutting part 58 along the shape that a surface base material where pressure sensitive adhesive is arranged on the stuck surface part can be parted to plural parts on the surface base material. When the seal 56 is peeled after it is temporarily stuck to the body to be stuck, the surface base material is cut from the cutting part and separated to plural parts in a state where the original form is lost by the adhesion of the pressure sensitive adhesive. By leaving the mark showing that action to peel the seal 56 is performed, unsealing is restrained.

Title: Pattern forming material
Inventor: TAKECHI SATOSHI
IPC: H01L21/027
Filed: 1982-12-13
Abstract: PURPOSE:To improve the accuracy of a pattern by mixing an electron beam resist with a halogen element or a halogen compound so as to prevent the accumulation of charges in the resist material. CONSTITUTION:An electron beam resist is mixed with a halogen element such as Br or a halogen compound such as AsF5 to prepare a resist material. The resist material is coated and baked, and the resulting resist film is patterned with an electron beam exposer. Since the accumullation of charges in the resist film is prevented when the film is exposed by irradiation with electron beams, the formed pattern causes no shift in location.

Title: Method for removing residual ga from liquid phase epitaxially grown wafer
Inventor: KAWASAKI MAKOTO
IPC: H01L21/304
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To precisely and quickly remove Ga remaining on the surfaces of highly reactive liquid phase epitaxially grown wafers as foreign matters. SOLUTION: By storing a cleaning solvent 21 containing a surface active agent in a cleaning tank 2 and maintaining the solvent 21 at >=35 deg.C with a heater 4, a wafer container 11 housing a large number of wafers W is dipped in the solvent 21 and an ultrasonic vibrator 3 is actuated. Residual Ga is quickly and easily separated and removed from the surfaces of the wafers W due to the synergistic effect of the surface active agent and ultrasonic vibrations and settles on the bottom of the tank 2. Therefore, the residual Ga can be removed completely in a short time through batch processing without giving any chemical damage nor mechanical damage to the wafers W. In addition, the cleaning operation can be automated and the Ga can be recovered inexpensively by separating the sediment (Ga) from the used solution (solvent).
