Title: Reforming method of cement
Inventor: SASAKI KO
IPC: C04B7/345
Filed: 1993-02-25
Abstract: PURPOSE:To produce a beta-C2S based cement high (about 2) in C/S ratio of C-S-H formed by hydration and small in the quantity of Ca(OH)2 as a by product. CONSTITUTION:The C2S is formed by forming a fine particle calcium silicate hydrate by hydrating a CS based cement clinker ore in a wet mill, filtering, drying and calcining at 600-1000 deg.C. The C-S-H having about 2 C/S ratio is formed from the contained C3S or C2S by hydrating the CS based cement clinker ore by adding water while pulverizing in the wet mill. The C2S is obtained by calcining to dehydrate the hydration reactional product containing the C-S-H having about 2 C/S ratio. The C2S is high in reactivity and increased in hydration reaction rate since the C2S is a super fine powder obtained by calcining the fine particle material formed in the wet mill. Further, since the C/S ratio of the C-S-H formed by hydration is high (about 2), the quantity of formed Ca(OH)2 is small.

Title: Starting means for semiconductor motor
Inventor: BAN ITSUKI
IPC: H02P6/06
Filed: 1982-03-10
Abstract: PURPOSE:To simplify the circuit configuration of a semiconductor motor by using as a position detection signal a counterelectromotive force and composing starting means of start control circuit for sequentially generating the first, second and third signals. CONSTITUTION:When a start signal is applied to a terminal 11a, a pulse signal 19 is outputted from a signal generator 11 for the prescribed period. Thus, the transistor 4 is conducted, thereby energizing the stator coil 3-1. The outputs of the detectors 2-1-2-3 are interrupted by the pulse signal 19 at this time. When the pulse signal 19 falls, a pulse signal 20 is outputted from a signal generator 12 during the prescribed period, thereby energizing a stator coil 2-2. When the signal 20 falls, a pulse signal 21 is outputted from a signal generator 13 for the prescribed period, thereby energizing a stator coil 2-3. Since the pulse signals 19, 20 are erased at this time, the energization of the stator coils 3-1-3-3 is controlled by the detectors 2-1-2-3 for detecting counterelectromotive forces.

Filed: 1981-03-13
Abstract: PURPOSE:To reduce mixed modulation noises visually without reduction of the level of a superposition signal by superposing a signal set to the frequency of 4/3 line offset to an angle modulation luminance signal and a low conversion modulation color signal. CONSTITUTION:A video signal inputted to a terminal 1 is sent to a DC component removing filter 2 to remove its DC component and inputted to a voltage control oscillator 4 through an adder 3 to modulate its frequency. The frequency- modulated video signal is outputted from a terminal 8 and simultaneously inputted to a phase comparator 6. The comparator 6 compares the frequency-modulated video signal with a signal having 3/4 line offset frequency which is outputted from a crystal oscillator 7 and outputs its error voltage. The error voltage is sent to an AC component removing filter 5 to remove its AC component and returned to the oscillator 4 through the adder 3. The video signal whose carrier frequency is controlled so as to be set to 3/4 line offset is mixed with an angle modulation luminance signal and a low conversion modulation color signal, reducing the mixed modulation noises of a reproduced picture.

Filed: 1989-02-15
Abstract: PURPOSE:To improve the reliability of an optical head and to reduce the cost by constituting second photodetectors, which detect the change of diffracted light, on a semiconductor substrate constituting a first photodetector as one body. CONSTITUTION:A first photodetector 1b and second photodetectors 11 and 12 are unified and are produced on one semiconductor substrate. A hologram element 2 diffracts and separates reflected light so that a focus error signal or a tracking error signal can be detected in the vicinity of the light reception plane of the first photodetector 1b. The focus error signal is taken out by operating the difference signal between respective difference signals 11a-11b and 12a-12b of second photodetectors 11 and 12 unified with the first photodetector 1b. Thus, the reliability of the optical head is improved and the cost is reduced.

Title: Dry etching
Inventor: SAGAWA SEIJI
IPC: H01L21/3065
Filed: 1988-02-18
Abstract: PURPOSE:To make it possible to conduct an excellent anisotropic etching operation by performing a bake treatment in a vacuum atmosphere just before etching. CONSTITUTION:A vacuum bake treatment is conducted at 100 deg.C or above just before an etching treatment is performed on an organic film using an inorganic film as a mask. For example, a silicon oxide film 3 of 1000Angstrom  in thickness is formed on the lower layer resist film, formed on a semiconductor substrate 1 using a sputtering method, as an intermediate film, and a patternized upper layer resist film 4 is formed thereon. Then, a silicon oxide film 3, which is an intermediate layer, is etched by conducting RIE using CF4+H2. Subsequently, the H2O and N2 contained in the resist film are driven out by conducting a vacuum bake treatment at 130 deg.C for 30 minutes. The lower resist film 2 is etched by conducting RIE using O2 just after the above-mentioned treatment. As a result, moisture is evaporated from an aperture part, the influence of moisture and the like, coming out from an organic film while an etching treatment is being conducted, can be suppressed and an excellent amorphous etching can be conducted.

Title: Manufacture of mis type semiconductor device using gallium arsenide
Inventor: FUJIEDA SHINJI
IPC: H01L21/318
Filed: 1988-02-18
Abstract: PURPOSE:To improve reproducibility, by a method wherein, after a gallium arsenide surface is made an arsenide-stabilized surface, Al or Ga element as a group III element is bonded, or radical or molecule containing the above element is stuck, and thereon a non-oxide system insulating film is formed at a temperature lower than or equal to 450 deg.C. CONSTITUTION:A process to eliminate a natural oxide film applying GaAs epitaxial growth or heat treatment of a GaAs substrate in an As atmosphere is performed, in order that the natural oxide film may not be contained in the GaAs surface. Then an As-stabilized surface is formed, and aluminum (Al) as an group III element is bonded. Non-oxide system insulator such as nitride or fluoride is deposited, as an insulating film film, at a temperature lower than or equal to 450 deg.C. Thereby, the reproducibility of a manufacturing process can be improved. Instead of Al, gallium (Ga) may be bonded to the stabilized surface.

CONSTITUTION:When the remaining quantity of seedling raising boxes kept at a supply device 32 becomes less than a predetermined number, and a photo sensor PH2 becomes OFF, chain lifts 34, 34 make a movement till lugs 36, 36 descend to the position of a limit switch LS3, and hereupon, lifts 34, 34 are stopped again. At this time, lugs 36, 36 that are holding a group of seedling raising boxes, are descending up to a height that is in the vicinity of the supply device 32. And when the number of seedling raising boxes the supply device 32 holds becomes zero, and a sensor PH3 becomes OFF, lifts 34, 34 make a movement till the next lugs reach the position of a switch LS1, that is, till lugs holding group of seedling raising boxes descend to the height of upper cylinders 38, 38, and a group of seedling raising boxes that has been held is delivered to support plates for cylinders 38, 38. Accordingly, an accident due to the poor supply of seedling raising boxes can be prevented beforehand.
