Title: Optical disk substrate
Inventor: HARUHARA MASAAKI
IPC: G11B7/24024
Filed: 1986-03-31
Abstract: PURPOSE:To prevent an adhesive from infiltrating to the center hold and to obtain an optical disk substrate for an optical disk with high quality by forming projecting part on an inner circumferential part of a bonded face of at least one optical disk substrate. CONSTITUTION:The part of inner circumference of the adhered face is formed in projecting shape to both two optical disk substrates 1A, 1B adhered together. A recording layer or a reflecting layer 2 is provided to the optical disk substrate 1B and they are adhered to the adhesives 3. Since the part of the inner circumferential part has projection, the adhesives is not intruded to the center hole and the surface of the optical disk substrate. Although the optical disk substrate 1A has no recording medium layer or a reflection layer 2, the similar advantages are obtained even when the layer 2 is provided.

Title: Focus servo controller for optical pickup
Inventor: MATSUNAMI HIROSHI
IPC: G11B7/085
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to perform stable focus search operation even under a vibrational condition. SOLUTION: A slice level Ls1 for obtaining a focus OK signal from a total signal is revised so as to become high until the level Ls2 after first focus search fails. Even when a lens position approaches slightly a focal point position by external vibration from a time t13 to the time t14 on the way of the focus search, and the total signal raises, since it doesn't exceed the slice level, the focus OK signal isn't generated. When the lens approaches the focal point position, the total signal exceeds the slice level from the time t15 to the time t16, and the focus OK signal becomes a low level. Meanwhile, a focus zero cross signal generated from a focus error signal changes from a high level once to a low level, and it turns a servo on when it raises to the high level further, and the focus search is ended.

Title: Rotary compressor
Inventor: ARAKAWA TOSHIKAZU
IPC: F04B39/12
Filed: 1984-04-13
Abstract: PURPOSE:To prevent the flow-out of lubricating oil into refrigeration cycle by setting, nearly at right angle, the direction of discharge of coolant from a compression mechanism part and the direction of a discharge pipe inserted into a sealed container, keeping a certain insertion gap.

Abstract: PURPOSE:To prevent reopening of operation from frosted condition by a method wherein defrosting operation is continued as it is in case the temperature of an outdoor heat exchanger is lower than a predetermined value even when the operation is stopped during the defrosting operation while the operation is stopped perfectly after finishing defrosting. CONSTITUTION:Even when operation is stopped during defrosting operation and an operation stopping signal is read in from an operation switch 11 into a control circuit 8, the operations of a fan 10, an indication or the like are out OFF but the defrosting operation is continued under a condition that a motor compressor 1 and a flow path switching valve 2 are put ON as they are if the temperature of the outdoor heat exchanger, which is detected by a temperature sensor 7 at that time, is lower than -3 deg.C. When the temperature of the outdoor heat exchanger has become lower than 10 deg.C, circuits for the motor compressor 1 and the flow path switching valve 2 are put OFF and the operation is stopped perfectly. According to this method, the operation may be prevented from starting from the frosting condition of the outdoor heat exchanger and the rise-up of room heating may be improved.
