Title: Optical head device
Inventor: KINOSHITA AKIRA
IPC: G11B7/135
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a device obtaining high output recording light, hardly receiving an effect due to birefringence of a recording medium and having high productivity by synthesizing transmitted first light and reflected second light to the same optical axis, converging them to a prescribed position and deflecting the light reflected from the recording medium in the prescribed direction. SOLUTION: Although a polarizing beam splitter 16 transmits a wavelength of a recording laser beam outputted from a first laser element 12 through, it reflects a reproducing laser beam with a short wavelength from a second laser element 20a. A second collimate lens 22 is fixed to the position that formed images of reflection light reflected by the polarizing beam splitter 16, converged by the collimate lens 22 and guided to a photodetector 20c for data and the reflection light emitted from the second laser element 20a and reflected by the optical disk D on the photodetector 20c become substantially the same shape in the position of the objective lens 10 that the wave front aberration of the light converged from the first laser element 12 to the recording surface of the optical disk D becomes minimum.

Title: Suntracking mechanism for solar energy-powered device
Inventor: MOTODA KENROU
IPC: F24S50/20
Filed: 1980-05-19
Abstract: PURPOSE:To perform the tracking operation to the sun of a solar energy-powered device at lower cost without the needs for a separate driving energy by providing a heat deformer mobile portion is altered in a fixed direction by the irradiation of solar radiation beam and directly turning a solar energy collector by the displacement of the heat deformer. CONSTITUTION:When setting up a heat collector 5 by turning it toward the sun, the sunlight is reflected and focused by a reflection plate 6 and then irradiated on a collector 7, whereby heating a heat medium inside the collector 7. At this time, no solar radiation beam is irradiated on a heat deformer 10, e.g., bimetal, etc., so that the thermal deformation of the heat deformer is slight. Then, when solar radiation beam is gradually displaced out of the collector 7 as the sun moves and then irradiates on the heat deformer 10, the heat deformer 10 is deformed by thermal expansion, whereupon oppositely directed turning torque acts on the heat collector 5 and the heat deformer 10, but the heat collector 5 alone is turned and its attitude is controlled because the reverse turning of the heat deformer 10 is hindered by a reverse-turning preventing mechanism 18b in a supporter 15b for the heat deformer 10.

Title: Heat transfer recorder
Inventor: FUJIWARA SUSUMU
IPC: B41J17/08
Filed: 1989-03-16
Abstract: PURPOSE:To obtain a heat transfer recorder excellent in a color reproducibility by setting the carrying speed of an ink sheet faster than that of a recording paper and by causing a recording paper carrier means to differ from an ink sheet carrier means in the drive timing. CONSTITUTION:During a transfer process, a stepping motor 30 is driven and a paper discharge roller 12 and a platen roller 35 are driven to rotation. Further, the reduction ratio of pulleys 34, 35 is set so that said paper discharge roller 12 is faster than said platen roller 5, thereby giving a stale back tension to a recording paper and preventing the crumple and oblique movement of said recording paper 11 by its sagging. On the other hand, an ink sheet carrier system also uses one stepping motor 41 and the reduction ratio of pulleys 45 and 46 is set so that an ink sheet take-up roll 9 rotates faster than an ink sheet carrier roller 7. Therefore, the ink sheet carrying speed of said ink sheet carrier system is set about 6% faster in comparison with the recording paper carrying speed of a recording paper carrier system. Then, even if an ink sheet 2 expands by heat on the discharge side of a thermal head 4 pressure welding part, it is possible to avoid the generation of crumples and defective carrying due to sagging of the ink sheet.

Title: Input buffer circuit for semiconductor integrated circuit
Inventor: KIHARA YUJI
IPC: H03K17/16
Filed: 1990-03-15
Abstract: PURPOSE:To realize a high speed operation by providing a resistance circuit connected in series to a logical gate circuit between a first power source potential and a second power source potential, and decreasing a through-current at the time when an input signal level is varied. CONSTITUTION:In response to an input voltage Vin, a transistor 12 or 13 is turned on, and an inverted output voltage VAout is outputted. In this case, when the input voltage Vin is, for instance, 1.4 or 1.5V, a through-current Ip tends to flow to the ground potential VSS from the power source potential VCC. However, since a resistance 16 is provided, an inflow to an input buffer 71 of the through-current is suppressed. Accordingly, the through-current Ip to a small peak value flows, and in addition thereto, since the resistance 16 is connected to a power source line 61, a voltage fluctuation at the time when the through- current flows is generated in a node Na for the most part. In such a way, since the power source potential VCC and the ground potential VSS are scarcely fluctuated, a high speed operation of a device is realized.
