Title: Semiconductor device and manufacture thereof
Inventor: SHIODA IKUO
IPC: H01L21/265
Filed: 1991-03-01
Abstract: PURPOSE:To maintain a semiconductor device in a simple and compact construction and to manufacture it by a simple manufacturing process in case of easing a lattice constant difference between a substrate of a single crystal Si and an InP layer. CONSTITUTION:An entitled semiconductor device has a substrate 1 of a single crystal Si and an InP layer 2 formed on the substrate 1 where a driven layer 3, in which atoms larger than an Si atom in radius are driven, is formed in the substrate of the single crystal Si. Since this driven layer is formed so that concentration of atoms may be increased toward the surface of the substrate, it functions as a buffer layer easing a lattice constant difference between the single crystal Si substrate forming the substrate and InP to be formed on the substrate; thereby, the InP layer of high quality can be formed directly on the substrate.

Title: Transfer type elecrophotographic copier
Inventor: MORIKAWA TERUO
IPC: G03B21/00
Filed: 1978-05-19
Abstract: PURPOSE:To enable size reduction by simple structure and easy confirmation of blank exposure condition, by using one lamp both for illumination of the original to be copied and for illumination of blank exposure. CONSTITUTION:In exposing original O with short-focus small imaging element array 4, plate 16 is restored to the full line position with rotary solenoid 17, the light path between array 4 and original O is opened, and the static latent image of original O is formed on photoreceptor 1'. When plate 16 is inclined to the broken line position, the light path between them is interrupted, the light emitted from lamp 6 is reflected and falls on array 4, and this uniform illumination light is used for blank exposure. The light emission amount of lamp 6 during blank exposure is set to a lower level than that during illumination of original O for forming a latent image, permitting power consumption to be cut down and temperature rise of the inside of copier to be prevented.

Title: Driving method for liquid crystal display element
Inventor: NAKANOWATARI JUN
IPC: G02F1/133
Filed: 1987-03-16
Abstract: PURPOSE:To permit displaying of medium contrast by applying a 1st voltage which puts the arrangement state of liquid crystal molecules into a 1st state and a 2nd voltage which puts the arrangement state of the liquid crystal molecules into the 2nd state alternately between the electrodes of 1st and 2nd glass substrates at the frequency higher than the flickering frequency of the human eyes. CONSTITUTION:The 1st voltage which puts the arrangement state of the liquid crystal molecules into the 1st state and the 2nd voltage which puts the arrangement state of the liquid crystal molecules into the 2nd state are applied alternately between the electrodes of the 1st and 2nd glass substrates at the frequency higher than the flickering frequency of the human eyes. For example, green light and red light arrive alternately at the human eyes 6 when the voltage of an 'H' level and the voltage of an 'L' level are alternately applied to one transparent electrode of the liquid crystal display element. Since the frequency of the voltage change is larger than the flickering frequency, the human eyes 6 cannot discriminate the green light and red light. The light is thus visible as the intermediate color of the green and red.
