Title: Optical sensor unit
Inventor: KUMANO KATSUFUMI
IPC: H01L27/14
Filed: 1988-04-15
Abstract: PURPOSE:To prevent occurrence of a shift in the relative position between plural lenses and plural optical sensors due to a temperature change so that rays of light can surely be transmitted to the sensors and the reliability of the title sensor unit can be improved by providing the lenses and optical sensors in one transparent substrate. CONSTITUTION:This optical sensor unit 19 is constituted of numerous semispheric minute lenses 12 assembled in a transparent substrate 10 for collecting rays of line to an original 8 placed beneath the unit 19 and plural optical sensors 16. The plural sensors 16 are fixed to the end face of the base plate 10 on the original side for reading the original 8 by receiving reflected rays of light from the original 8. The lenses 12 and sensors 16 are respectively arranged in one lines in the length direction of the substrate 10 and constitute a lens array and sensor array. The sensors 16 are fixed to the positions corresponding to individual lenses 12, namely, positions which are nearly below the lenses and where the rays of light condensed by the lenses 12 are not intercepted. Since the lens array and sensor arrays are fixed to one substrate in such way, this optical sensor unit can be manufactured at a low cost.

Title: Formation of semiconductor device
Inventor: MIYAZAWA SEIICHI
IPC: H01S5/22
Filed: 1983-05-25
Abstract: PURPOSE:To obtain a semiconductor device having a superative current strangulation effect by a method wherein the crystalline structure of a substrate or a semiconductor layer on a substrate is partially changed and a semiconductor layer having a structure in accordance with the previous crystalline structure is furthermore grown thereon. CONSTITUTION:A GaAs layer 12 including no impurity is grown in the form of single crystal on a GaAs substrate 11. Into the thus-grown layer, a Ga or As of a high concentration is implanted by means of an ion implantation. As a result, a part of the crystalline structure is changed and the single crystal portion remains in a strip shape, thus forming a high resistance layer 22. Then, an InGaP layer 13 is grown on the GaAs layer 12 including the high resistance layer 22. A part 33 within the layer 13, which is grown on the single crystal portion of the GaAs layer 12, is transformed into a single crystal. While, a part 23 grown on the high resistance layer 22 becomes amorphous or polycrystalline. Subsequently, a GaAs active layer 14 and InGaP layer 15 are laminated on the InGaP layer 13 and finally electrodes 16 and 17 are formed, whereby a semiconductor laser is formed. The stripe region strangulated between high resistance regions 20 is formed without expanding proximate to the substrate and hence the passage of a current 18 flowing between the electrodes is restricted to the strangulated region. The thus-formed semiconductor laser is therefore capable of oscillating at a low current density.

Title: Television signal multiplexing system
Inventor: KURITA YASUICHIROU
IPC: H04N7/12
Filed: 1986-04-24
Abstract: PURPOSE:To prevent a visual harm on the reception picture of a conventional television receiver from occurring even when a high frequency-band brightness signal is multiplexed by converting a high frequency-component signal so that its frequency spectrum is in a form opposite that in the low frequency band, then multiplexing. CONSTITUTION:A high frequency band component YH of 4.2 6MHz is extracted from a brightness signal Y by a band-pass filter BPF 1. The YH is subsampled by a switcher 3 by using a phase controlled sample frequency of nfh*, and only a necessary frequency band component is extracted by a BPF 4 and made a multiplex signal YH'. The nfh* is generated by a phase inverting circuit 6 by means of phase control in which the nfh is phase-inverted based on a controlling signal from a control signal generating circuit 6. Of the multiplex spectrum of the high frequency band signal, the components of 4.2 6MHz of a signal Y is reflected to 1.2 3MHz and multiplexed. At such a time, since the components are multiplexed in a frequency area comparatively high as a signal level, the interference on a picture of a prevalent conventional receiver is not noticeable.
