Title: Manufacture of semiconductor device
Inventor: SAWADA KAZUYUKI
IPC: H01L27/10
Filed: 1993-03-25
Abstract: PURPOSE:To form an insulating film of a film thickness having a sufficient etching resistance on the diffused layers of a MOS transistor without decreasing the area of a contact hole. CONSTITUTION:An SiO2 film 14 is deposited on a MOS transistor using a polycrystalline Si wiring 10 covered with an SiO2 film 12 as its gate by the reaction of ozone with a TEOS film formed by a normal pressure CVD method. In this reaction, as the deposition rate of the film 14 on an Si film is higher by three times compared with that of the film 14 on the SiO2 film, the film 14 can be formed thicker on an N-type diffused layer 6 than that on the film 12. Then, after a contact hole 16 is formed, a polycrystalline Si film pattern 18, a dielectric film 20 and a polycrystalline Si film pattern 22 are formed in order and a capacitor element connected to the MOS transistor is formed.

Title: Immobilized enzyme membrane
Inventor: KOKADO HIROYOSHI
IPC: C12N11/04
Filed: 1980-05-21
Abstract: PURPOSE: An enzyme is immobilized on a porous membrane that consists of the dense skin layer and the sponge layer in which pore diameters varies and the pores with mixmum diameters gather to the center part, thus preventing the immobilized enzyme from releasing off while it is used and stabilizing the activity.  
     CONSTITUTION: In the course of the production of a porous membrane, the dope is casted on the glass plate in a prescribed thickness and coagulated in cold water into a film. The resultant film is pressed to make the pore diameter small at the farthest distance from the dense layer. Then, the enzyme is included in the membrane and immobilized by crosslinking. As a result, the immobilized enzyme is included in pores whose diameter is maximum at the center part in the cross section and becomes smaller as going away from the center. Thus, the membrane develops the anchor effect to keep the immobilized enzyme in the membrane and stabilize the activity even when used for a long period of time.

IPC: H04N5/63
Filed: 1981-04-30
Abstract: PURPOSE:To prevent a power source from being connected frequently by providing an infrared sensor and a timer, and automatically turning off the power source when nobody watches a television. CONSTITUTION:The output of an infrared sensor 1 arranged on the front surface of a TV receiver is amplified by an amplifier 2 and converted into a rectangular wave, which is further converted into a DC output by an AC/DC converter 3. This DC output is compared with a reference voltage ER by a comparator 4, whose comparison output drives a DC relay 7 through a driving circuit 5. A counter 8 and a time setter 9 constitute a timer device and the counter 8 starts counting a clock signal supplied from the setter 9 at the point in time when the DC relay 7 is energized; when its count value attains a set point, a photorelay 11 is energized. The contact A of the photorelay 11 is inserted into the power line of a TV circuit 13 in series to a switch 12. Then, the photorelay 11 operates at the set time after a viewer lefts, thereby power on to the TV circuit 13 is turned off.

IPC: H04B1/707
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To provide the code division multiplex communication equipment capable of high speed synchronization, with a simple configuration and small power consumption in the standby state. SOLUTION: When a specific pattern included in a reception signal by a reception antenna 10 is detected by a SAW matched filter 12, the filter 12 provides an output of a correlation peak. A tip synchronizing signal generator 13 detects the correlation peak and generates a synchronizing signal at a point of time elapsed from the detection point of time by a prescribed time. An orthogonal PN signal generator 20 generates a predetermined orthogonal PN code synchronously with the synchronizing signal. Furthermore, a carrier generator 23 generates a carrier based on an output from the SAW matched filter 12. The generated carrier is modulated by an output of the orthogonal PN signal generator 20.  Then the signal received by the reception antenna is multiplied with a modulation output by a multiplier 28 and integrated by an integration device 29, from which a signal restored to the original signal is outputted.

Title: Production of hologram filter for recognition, hologram filter for recognition and recognizing device using this filter
Inventor: HIRANO TAKASHI
IPC: G03H1/04
Filed: 1989-03-22
Abstract: PURPOSE:To obtain an instantaneous and stable identification power by classifying patterns to plural groups with the patterns which are not analogous to each other as elements, shifting the positions of the individual patterns in the groups, exposing the patterns simultaneously, and superposing the pattern groups on each other, then exposing the same by each group so as to have different angles of reconstruction light. CONSTITUTION:The plural pattern groups are classified to the plural groups with the patterns which are not analogous to each other as the elements. The positions of the individual patterns in the groups are shifted and the patterns are simultaneously exposed. Further, the pattern groups are superposed on each other and are exposed so as to have the different angles of the reconstruction light with each group. Since the pattern groups of the low analogousness are recorded within the same groups at this time, the wrong recognition of the analogous characters and symbols in the same photoelectric converter is decreased. Since the nonanalogous characters and symbols are recorded in parallel, the number of multiple exposings is decreased and the degradation in diffraction efficiency is prevented. The recognition which allows instantaneous decision with the decreased fluctuations in the decision accuracy by the patterns is executed in this way.
