Title: Manufacture of semiconductor device
Inventor: OTANI YUKIHIRO
IPC: H01L23/522
Filed: 1987-08-07
Abstract: PURPOSE:To form a contact hole for a source-drain which can enhance an integration density without requiring a precise alignment operation by a method wherein a gate electrode is beforehand covered with a second poly-Si film and is protected. CONSTITUTION:A source 9 and a drain 10 (a pattern 9a) are formed on the surface of a p-type Si substrate 8 on both sides of a gate electrode 11 (a pattern 11a). After that, an SiO2 film 12 is formed by a thermal oxidation method or a CVD method; in addition, a poly-Si film 13 is applied by the CVD method. Then, this poly-Si film 13 is patterned by using a pattern 13a which is wider than a pattern 11a for gate electrode formation use in a channel length direction. Then, after a PSG film 14 as an interlayer insulating film has been applied, it is patterned by using a pattern 15a for contact hole formation use. During this process, an alignment margin between the pattern 15a and the pattern 11a for gate electrode formation use may be zero. If this assembly is etched by using a hydrofluoric acid-based etching solution by making use of the poly-Si film 13 as a mask, a contact hole 15 is formed. Because the alignment margin may be zero, a manufacturing operation is easy.

Filed: 1984-09-22
Abstract: PURPOSE:To reduce the load of an operator and to ensure the efficient and smooth operations by displaying the input characters with low duty at the relevant partial display area of a liquid crystal display device within a display area where the input operation is carried out. CONSTITUTION:The duty is increased with reduction of contrast on a display screen in a state where the displays are carried out over the partial display areas A and B. Thus a short circuit is secured between a fixed contact 20 and a common contact 17 of a switch SW1 of a switching element 15 by a control circuit 6. While a common contact 23 of switch SW2 has a short circuit with a fixed contact 26.

The neutron absorbing rods packed with only the EuO3 are disposed particularly to the three pieces from the front end of the wing where the neutron irradiation quantity is large. The neutron absorbing rods packed with the neutron absorber mixed with 50% eac of the EuO3 and the B4C are disposed to the two pieces following to the above-mentioned three pieces. The neutron absorbing rods packed with the B4C are disposed in the remaining 16 pieces. Hollow pipes consisting of hafnium are used for coating pipes. The halfnium is the neutron absorbing material by its own (n,r) reaction. The life of the control rod is thus prolonged.

Title: Power supply for all-direction display unit of plane picture at angle of 360 degree
Inventor: KURUTO EFU BIYUTSUFUERU
IPC: G09F13/32
Filed: 1989-08-02
Abstract: PURPOSE: To reduce the variation of light by making an image carrier with a specific rotational frequency or higher and selecting a ratio of a bright period of a luminous flux and the rotational frequency so that the remaining luminance variation cannot be perceived by visual organs of a human being according to circumstances. CONSTITUTION: The range of at least 50%, preferably 75%, especially 90% of a maximum of the luminous intensity is defined as the bright period. It is preferable that a light source following a voltage curve shown by a short and long dash alternating line L is used. This voltage curve L indicates 500Hz voltage or current pulse (corresponding to 250Hz AC voltage), and the sum total of bright periods is about 50% of the overall rotation time because of the afterglow characteristic (fluorescence characteristic or incandescence characteristic of filaments) existing in any lamp. It is most preferable that the light source uses a ripple waving between 90 and 100% luminous intensity as shown by a second continuous line Z in the lowest stage. Thus, the bright period becomes 100% of the rotation time.

Abstract: PROBLEM TO BE SOLVED: To measure the position of a probe chip in a near-field optical microscope by using a small apparatus and by a simple adjustment by a method wherein laser light for control is transmitted by using an optical fiber so as to be radiated to the probe chip. SOLUTION: In a measuring method, a probe chip 5 which radiates laser light for observation is vibrated at a sample 9, and the distance between the tip of the probe chip 5 and the sample 9 is decided on the basis of the amplitude of the vibration. In addition, an optical fiber 3 is used, laser light, for control, at a prescribed wavelength is transmitted from a semiconductor laser 1 so as to be radiated to the probe chip 5. In addition, by using the interference between reflected light at the end face 3a of the optical fiber 3 and scattered light from the probe chip 5, the position of the probe chip 5 from the end face 3a of the optical fiber 3 is measured in a noncontact manner. In this manner, an optical part which is composed of the semiconductor laser 1 and the like and an interference part are separated, and both parts are coupled by the optical fiber 3. Thereby, the respective parts can be separated and arranged under separate environments.

Title: Receiver in common use for broad band and narrow band
Inventor: FUNAI MIKIO
IPC: H04B1/18
Filed: 1986-08-25
Abstract: PURPOSE:To simplify the processing method of a signal processing unit by using a Thomson filter whose group delay characteristic is flat as a filter for a narrow band system and synthesizing the result of filtering with a broad band system so as to minimize the increase in the scale of a reception system. CONSTITUTION:A signal through a narrow band filter 8 is synthesized with a signal of a broad band system in a power combiner 3. If both the signals are combined simply, the frequencies of the narrow band system are retarded timewise at their center frequency by tauA+tauF. Thus, a delay line 9 having a flat frequency characteristic is provided to the broad band system to make its delay time tauDL into tauDL=tauA+tauF (where tauF is the center frequency of the filter) thereby allowing the combination in phase. Since the signals are synthesized nearly in phase in the pass band of the narrow band filter 8, the signals are synthesized at the output terminal of the power combiner without being much affected onto its amplitude characteristic.
