Abstract: PURPOSE:To simplify a control system, by installing a conveying subject loading cradle rotatably on a skid capable of moving toward both forward and backward on the base, while converting the forward and backward motion of the skid into the rotary motion of the cradle. CONSTITUTION:Operating a drive motor 10, a transfer bar 8 is retreated whereby the drive motor 10 comes to a stop when a cradle 18 supported by a skid 12 gets positioned just under a carrier 28.

Title: Electrostatic actuator
Inventor: KOEDA SHUJI
IPC: H02N11/00
Filed: 1992-05-14
Abstract: PURPOSE:To increase pressure generated and displacement and also, reduce driving voltage so as to prevent dielectric breakdown by charging high- permittivity fluid having bubbles mixed or porous high-permittivity elastic substance into the space between a vibration plate and a counter electrode, in an electrostatic actuator which generates coulomb force and defaces the vibration plate. CONSTITUTION:High-permittivity fluid 11 such as glycerine, nitrobenzene, etc., is charged into the space 5 between a counter electrode 4 and a vibration plate 3, when sealing it, by vacuum suction. Here, in the high-permittivity fluid 11, minute bubbles 12 of several microns are mixed at charge with a view to absorb volume change. Since the distance between the counter electrode 4 and the vibration plate 3 is minute at several microns, the bubbles 12 are never maldistributed by surface tension. What is more, in the case of having many mixed bubbles 12, the permittivity becomes small as a whole, and the output drops, so the quantity of mixed bubbles 12 shall be minimum within the range which fulfills required displacement.

Title: Data pulse detecting method and data pulse receiver
Inventor: BROWN ANTHONY K DALE
IPC: H03K3/037
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To perform automatic hysteresis adjustment by controlling tail current based on a clock signal and continuously adjusting a data pulse detection level. SOLUTION: Data pulse detectors 200 and 202 execute threshold detection depending on the value of a hysteresis control signal. A hysteresis control signal generator 208 includes a pulse detector 200 for peak detection and receives a clock signal as input. The clock signal is received by the two detectors 200 and 202. An output of the detector 200 drives a peak detector 206 and the detector 206 controls both hysteresis levels of the detectors 200 and 202 owing to feedback. As a result, the hysteresis level of the detector 200 is adjusted so as to sufficiently monitor the peak amplitude of the clock signal. Also, the detector 206 has another output which sets another pulse detector to be driven at a low speed on a specific hysteresis level.

Title: Optical disk and original board exposure machine thereof
Inventor: MIZUTA OSAMU
IPC: G11B7/125
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To accurately read recorded information by expressing a groove- shaped depth arranged on a substrate by D, and making the depth be in a range of 0.16λ/n<=D<=0.20λ/n (λ: recording laser wavelength, (n): refractive index of substrate). SOLUTION: A land, a groove, a depth and width of the groove on a disk are expressed by L, G, D, and W respectively. When an optimal shape of the groove is selected for track pitch, it varies by a wavelength of a recording/ reproducing light beam, a beam radius, and a refractive index of a substrate, and their relationship is as follows. Depth of groove D=k1×λ/n (λ: laser wavelength n: refraction index 1.58, k1: constant) Groove width = k2×ω (ω: beam diameter, k2: constant) Therefore, it is possible to accurately read recorded information by determining k1 and k2 from the above and restricting groove width: 0.39ω<=W<=0.64ω, and groove depth: 0.16λ/n<=D<=0.20λ/n.

IPC: C30B25/16
Filed: 1991-04-24
Abstract: PURPOSE:To easily control carrier density even in a low-carrier-density region of a main compound semiconductor layer by changing the thickness of a buffer layer. CONSTITUTION:The following are provided; a preliminary growth process wherein compound semiconductor is stuck on an Si substrate 12 at a low temperature incapable of obtaining single crystal, and a buffer layer 14 is formed, and a main growth process wherein compound semiconductor is crystal-grown on the buffer layer 14 at a high temperature capable of crystal-growing single crystal, and a main compound semiconductor layer 16 is formed. When a hetero epitaxial substrate 10 is manufactured in the above manner, the carrier density in the main compound semiconductor layer 16 is controlled by changing the thickness of the buffer layer 14. For example, the buffer layer 14 is formed on the Si substrate 12 at 450 deg.C by using an MOCVD equipment, and a GaAs layer 16 of 4mum in thickness is crystal-grown at 700 deg.C on the buffer layer 14. In this case, the carrier density of the GaAs layer 16 changes as shown by a graph in figure, when the film thickness of the buffer layer 14 is set as 9nm, 18nm and 27nm.
