Title: Surface acoustic wave element
Inventor: KITANO TOSHIHIKO
IPC: H03H9/42
Filed: 1990-10-09
Abstract: PURPOSE:To realize a low loss surface acoustic wave element by always making the propagation speed of surface acoustic wave of the electrode digit of a couple of interdigital electrodes arranged opposite to each other equal to the propagation speed of a surface acoustic wave of the inner side signal extraction electrode inserted between the electrode digits, a metallic conductor electrode and the propagation speed of the surface acoustic wave in a free space inserted among the electrodes. CONSTITUTION:The propagation speed of a surface acoustic wave of electrode digits 6, 8 is always made equal to the propagation speed of a surface acoustic wave of inner side signal extraction electrodes 5, 7 inserted between the electrode digits, a metallic conductor electrode 4 and the propagation speed of a surface acoustic wave in a free space inserted among the electrodes. Then the surface acoustic wave radiating from the point A of the interdigital electrode is refracted at the inner side signal extraction electrodes 5, 7 and the metallic film electrode 4 and propagated perpendicularly to the electrode digit 8 in the electrode digit of the tilted interdigital electrode 3 opposite thereto, and reached to a point B. Thus, the increase in the loss of the propagate surface acoustic wave is not entirely caused.

Title: Recording medium and recorder
Inventor: SATO KOICHI
IPC: C08L101/00
Filed: 1993-10-05
Abstract: PURPOSE:To obtain a rewritable recording medium in which a large-area and high- precision picture image can be displayed and to obtain sufficient properties of films and stability for repetition of writing by using a high-molecular liquid crystal having a specified or larger weight average mol.wt. and a specified or smaller ratio of weight average mol.wt./number average mol.wt. CONSTITUTION:An oriented film 3 is formed on a substrate 4, on which a recording layer 2 is formed. Further, polarizing films 1, 1' are formed on the recording layer 2 and on the back surface of the substrate 4, respectively. The high- molecular liquid crystal used for the recording layer 2 of the recording medium has >=60000 weight average mol.wt. (Mw). If Mw is <60000, cracks may generate in the liquid crystal or enough characteristics as a film are not obtd. Further, the high-molecular liquid crystal has <=7 ratio (Mw/Mn) of the weight average mol.wt. (Mw) to the number average mol.wt. (Mn). If it exceeds 7, the distribution of mol.wt. becomes too wide and such problems that the liquid crystal can not be uniformly applied or uniformity of the recording film is lost by repeating the recording and erasing in many times.

Title: Speaker
Inventor: SAWADA YOSHIO
IPC: H04R1/28
Filed: 1994-11-04
Abstract: PURPOSE: To improve tone quality and to relax restrictions on design. CONSTITUTION: When sounds from a speaker unit 30 attached to a baffle plate 14 in a cabinet 11 of a speaker 10 are guided by the sound path formed in the cabinet 11, they are emitted to the outside from plural slits 12 provided in the cabinet 11. Plural peaks due to resonance are generated in the acoustic pressure characteristics when dimensions of the sound path are made longer at the time of guiding the sounds from the speaker unit 30 by the sounds path, but bands of these peaks due to resonance can be changed by the length of the sound path. Further, bands of these peak frequencies tend to fall by slits 12 provided in the cabinet 11; and therefore, the frequency of sounds to be emphasized can be controlled in accordance with the length of the sound path and setting of slits 12.  Since the design of the cabinet 11 can be realized only with slits 12, the tone quality is improved, and restrictions on design are relaxed.

IPC: H04N9/73
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To provide the image pickup device that detects white balance properly with a simple configuration. SOLUTION: A mean value of color signal levels in a plurality of very small areas that are divisions of a photographed image is detected as a color evaluation value of each color (S2), the color evaluation value of a G signal in the color evaluation values is used for a luminance level (S3). In the case that the luminance level exists between 1st and 2nd threshold levels (S4), hue information is detected, based on the color evaluation value (S6), and when the hue information is within a 1st hue range (S7), the number of valid small areas is counted (S8) or all the very small areas (S9), the count is compared with a 3rd threshold level (S10).  When the count is larger than the 3rd threshold level, a weight mean based on the luminance level of the hue information in the valid very small areas is calculated (S11), and when the count is smaller than the 3rd threshold level, a mean value of the hue information of the entire image is calculated (S12) and the color signal level is corrected, based on the result (S13).

Title: Manufacture of semiconductor device
Inventor: OKAMURA KENJI
IPC: H01L21/822
Filed: 1991-10-21
Abstract: PURPOSE:To obtain a semiconductor element including a capacitive element which has a large capacitance value by forming a lower electrode of the capacitive element on a semiconductor substrate, subjecting the lower electrode to nitride atmosphere after the lower electrode has been rapidly heated under a reduced pressure, forming a nitride film over the lower electrode by heating, and depositing a silicon nitride film over the nitride film by CVD techniques. CONSTITUTION:A silicon oxide film 12 is formed on a semiconductor substrate 11, and an opening is then made in the silicon oxide film. A lower electrode 13 which is made of a polysilicon film is further laid over the silicon oxide film. The lower electrode 13 is then rapidly heated under a reduced pressure in a quick-heating apparatus, and is subsequently heated in nitride atmosphere, so that the surface of the lower electrode 13 is thermally nitrided. A silicon nitride film 15 is then deposited on the lower electrode 13 by means of a low pressure chemical vapor deposition system. During this time, since the surface of the lower electrode 13 is already nitrided, the surface of the lower electrode 13 undergoes no oxidization when the semiconductor substrate 11 is introduced into the core tube of the low pressure chemical vapor deposition system. Thereby a thin capacitive dielectric film can be obtained, and hence a semiconductor element including a capacitive element having high capacity can be obtained.

Abstract: PURPOSE:To attain sure synchronization at a monitor by setting a low-order M-bit to level larger than a blank level of a video signal in a video signal processing circuit making solarization while the low-order M-bit of an N-bit quantization data is set to a fixed level. CONSTITUTION:An input video signal is supplied to a digital signal processing circuit 14 as, e.g., an 8-bit quantized video signal data by an A/D converter 12.
