Title: Manufacture of optical disk medium
Inventor: SUDO KATSUNORI
IPC: B29D17/00
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To easily manufacture an optical disk medium with less warping and birefringence by positioning two substrates coated with adhesive on recording surface sides oppositely to each other and applying compression force in the radial direction of these two substrates. SOLUTION: A first substrate 101 and a second substrate 102 coated beforehand with the adhesive 103 are overlaped, confronting the recording surface sides, that is, recessed face sides with each other. In such a process, since the recessed face sides confront each other, the central parts of the substrates 101 and 102 is in a floating state. In such a floating state, when pressure is applied from both directions, as shown by the arrows, the substrates are stuck, while smashing each other flatly. At this time, since the birefringence caused by stress is canceled by the birefringence provided in the substrate itself, the birefringence as a whole is suppressed to be small.

Filed: 1990-06-15
Abstract: PURPOSE:To attain miniaturization by providing a magneto-resistance effect element (MR element) and a transformer for signal detection which converts a current change due to the change of electrical resistance of the MR element to a voltage change integrally on a substrate. CONSTITUTION:The transformer 13 for signal detection is comprised of lead wires 4a, 4b drawn out from both terminals of the MR element 3 and formed spirally on a first insulating layer 2, a magnetic substrate 1, and a magnetic layer 6.

Title: Electronic control exhaust recirculation apparatus
Inventor: NAKAMURA MITSUROU
IPC: F02M25/07
Filed: 1977-12-28
Abstract: PURPOSE: To recirculate gas suitably on the basis of the operational condition.  
     CONSTITUTION: A proper EGR ratio is determined on the basis of the signals from a suction-air sensor 35 and an engine rpm. sensor 37 Depending on the ratio, a signal is put out from a control circuit 10 to a solenoid valve 11. The value of a control negative pressure P o  is regulated in proportion to the determined opening of the solenoid valve 11, which is let to a pressure chamber 16 of a differential-pressure converter 12 through a duct 19. As negative pressure rises, the diaphgram 14 is displaced upwards against a return spring 34 because the pressure influence area of the diaphgram 14 is larger than that of the diaphgram 13. The valve seat 20 of the diaphgram 13 therefore makes an atmosphere inlet pipe 21 reduce in opening. The result of less air dilution ratio increases the control negative pressure P 3  affecting the exhaust recirculation valve 6 to gain the opening of the control valve.

Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To provide a vibrator improved in mechanical strength, facilitated in stable mounting and reduced in fluctuation of characteristics as well by integrating a vibrator reducing the thickness at a vibrator terminal part rather than the thickness at a vibrator central part while having a bevel-shaped or convex-shaped cross section with a supporting part.

Since the electrode 21 for excitation is partially formed at a vibrator section, vibration energy is enclosed under the electrode 21 for excitation and vibration displacement is maximized at the central part of the vibrator section and attenuated gradually toward the terminal part. Further, since the terminal part of the vibrator section is bevel-shaped, the attenuation amount of vibration displacement at the terminal part of the vibrator section is increased.  Further, the terminal part of the vibrator section is integrated with the supporting part 20 and variations in machining accuracy such as chipping or surface roughness at the terminal part of the vibrator section is reduced.

Title: Method for storing data to vram
Inventor: MATSUNAGA TOMOHITO
IPC: G06F19/00
Filed: 1992-05-27
Abstract: PURPOSE:To shorten a load period of time by conducting data registration on a CDROM in matching with a table of a VRAM so as to decrease a physical load number of times. CONSTITUTION:Data forming one stage are unified in one block unit and registered in advance. Thus, since information required for one stage of a VRAM is divided into blocks and unified in advance, data are read by one time physical loading. If the data are directly overwritten on BAT, SAT, CG, SG of the VRAM, they are used as the data of the VRAM as they are. Thus, one program describing simultaneously the data read processing and data write processing to the VRAM at every type of data is enough. Furthermore, the physical loading to take much time is one time enough, then data read period of time from a CDROM is shortened.
