Filed: 1985-07-17
Abstract: PURPOSE:To increase the degree of freedom of designing a mask pattern by forming an Si oxide film obtained by baking a silicon compound dissolved in an organic solvent on a semiconductor substrate, and forming a photoresist film pattern thereon. CONSTITUTION:A P-well 2 is formed on an N-type Si substrate 1, and an element separating region 3 is formed. Then, a gate oxide film 4 is formed, and a gate electrode 5 is formed. Thereafter, a silicon compound dissolved in an organic solvent is coated, and a silicon oxide film 6 obtained by baking it is formed on the entire surface. After a photoresist film 7 is then coated on the entire surface, it is patterned, and a P-well 2 is opened. With the film 7 as a mask high dose ions are implanted to form source and drain region 8. Subsequently, the film 7 is separated and removed. According to the manufacturing method, since the mask 7 is used as the mask to perform a high dose ion implantation, no undercut is formed, the degree of freedom of designing the designing margin of the mask pattern can be increased, and the element can be microminiaturized.

Title: Magnetic field modulating type disk
Inventor: ICHIKAWA MARI
IPC: G11B5/82
Filed: 1988-06-29
Abstract: PURPOSE:To attain the overwrite recording of a signal at several MHz in a stable CSS (Contact Start Stop) system by making the surface of the protective film of a magnetic field modulating type disk, and making it larger than the roughness of a magnetic head surface. CONSTITUTION:The absorption between the magnetic head and the magnetic field modulating type disk is related to the surface roughness of the two facing surfaces. That is, when an uneven shape larger than the surface roughness of a magnetic head 4 is formed on the surface of a protective layer 3 of a magnetic field modulating type disk, close adherence with the magnetic head 4 can be prevented, and recording/reproduction is attained. Consequently, the overwrite-recording even for the signal at several MHz by means of the magnetic field modulation in the CSS system is attained. Thus, without largely damaging the points of non-contact recording, reproducing and erasing to be the characteristics of optical recording, the stable recording on the disk is attained.

Title: Impact dot printer
Inventor: KOSHIISHI OSAMU
IPC: B41J29/08
Filed: 1992-06-18
Abstract: PURPOSE:To constitute an impact dot printer reduced in noise by partially changing the cross-sectional area of the printing paper discharge route above the printing head or platen of the impact dot printer. CONSTITUTION:Noise generated from a printing head 8 and a platen 6 is partly absorbed by the sound absorbing material 7 provided on the under surface of a first printer cover 1 and unabsorbed noise passes through the printing paper discharge route formed between printing paper 4 and first and second printer covers 1, 2 to go outside of an impact dot printer 100 from a paper discharge port 15. However, when there is a part changing in cross-sectional area in a transmission route, the particle speed of a medium becomes discontinuous across the part and sound wave is reflected. Since the reflection of the sonic wave becomes large as cross-sectional area change quantity becomes larger and the protruding quantity of a sound arresting member 10 to the printing paper discharge route is larger than that of a sound arresting member 2a and the cross-sectional area change quantity of the member 1b is larger than that of the member 2a, large sound arresting effect is obtained.

Filed: 1979-12-08
Abstract: PURPOSE: To make possible the measurement of the voltage at arbitrary phase of input signal stably and highly accurately by comparing the input signal of a periodic waveform with a reference voltage forming a feedback loop.  
     CONSTITUTION: The input signal (y) of a periodic waveform is compared 2 with the output (y') of a voltage generating circuit 5, and the output of the comparision result is supplied to a buffer 3. Also, a frequency component is extracted from the signal (y) in a synchronizing circuit 7, and clock is formed and is then supplied to the buffer 3. Thereby, the compared output at an arbitrary phase of the signal (y) is stored in the buffer 3. The stored output (x) is averaged at 4 and is applied to the circuit 5. As a result, the voltage (y') is made equal to the voltage at the measurement point phase of the signal (y') and the voltage at an arbitrary phase of the signal (y) may be measured by measuring the voltage (y') with a voltmeter 6.

Title: Method and device for preparing tenplate expressing audible signal
Inventor: BURAIAN RII SUKATSUTO
IPC: G10L15/02
Filed: 1980-11-15
Abstract: Recognition of human speech is carried out by storing a template for each unit of speech to produce a dictionary of stored words and phrases. A given speech signal is converted to produce a template which is compared to the stored template to find the closest comparison. The word or phrase corresponding to the identified template is produced and displayed to complete the recognition of the speech signal. The speech signal is processed to produce two separate frequency components. The frequency components are processed to produce a DC signal proportional to the frequency of the frequency component. The frequency components are also rectified to produce amplitude signals corresponding to the envelope of the frequency components. The products [F1][F2] and [A1][A2] and ratios F1/F2 and A1/A2 of the pairs of frequency and amplitude signals are produced to generate a plurality of relational signals which comprise the templates corresponding to each speech signal. In building the dictionary each speech sample is submitted a number of times to produce an average template value together with the variants for each data point.

Title: Nonreflection switch
Inventor: SAKAKIBARA HITOSHI
IPC: H01P1/10
Filed: 1988-06-27
Abstract: PURPOSE:To eliminate the need for an expensive isolator and to reduce the product cost by connecting a 1st output terminal of a switch able to switch an electromagnetic wave supplied to the input terminal to the 1st or 2nd output terminal to the antenna and connecting the 2nd output terminal to a non- reflecting terminator. CONSTITUTION:With a switch S1 turned OFF and a switch S2 turned ON, the connecting point of the switch S2 is short-circuited to make the impedance when viewing the 2nd output terminal Y2 from a branch point parted by 1/4 wavelength infinite. Thus, a radio wave made incident from the input terminal X is fed to the 1st output terminal Y1 and radiated from the antenna 2. Furthermore, with the switch S1 turned ON and the switch S2 turned OFF, the impedance when viewing the 1st output terminal Y1 from the branch point is made infinite. Thus, the incident wave from the input terminal X is supplied to the 2nd output terminal Y2 and consumed by a termination resistor 3. In this case, no electromagnetic wave from the antenna 2 is radiated.
