Title: Method for splitting hardly marked-off substrate
Inventor: RUDAZ SERGE L
IPC: H01L33/48
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To efficiently split a substrate which is hard to be marked off in a high quality. SOLUTION: After a substrate which is hard to mark off is adjusted to a thickness suitable for cleaving treatment, one surface of the substrate is coated by growing a dielectric or nonductile material on the surface. The marking-off of the substrate is performed on the coated surface and the coating material plays the role of a marking-off facilitating layer and causes sufficient fracture propagation. It is also possible to shield a cutting tool from piezoelectric discharge and, at the same time, to dissipate the heat generated by the marking-off and splitting of the substrate by placing an arbitrarily selected metallic on the marking-off facilitating layer. When the marking-off is not made on the coated surface, but on the other surface, the thickness and hardness of the coating film are set so that the marked-off surface may be maintained in the optimum tension state.

Title: Objective lens for phase difference microscope
Inventor: SUDO TAKESHI
IPC: G02B21/02
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To completely decrease stray light entering an image formation surface in an objective lens for a phase difference microscope having a phase plate provided with a phase film on the bonded surfaces of a pair of bonded parts whose lens surfaces coming in contact with air are plane by forming the bonded surfaces as planes inclined to an optical axis. SOLUTION: The phase plate 1 arranged at the position of the pupil of the objective lens is constituted of a pair of bonded parts 1a and 1b, and a ring-like extinction area 2 to lower the transmissivity of 0th order light and the phase film 3 to modulate the phase by 90 deg. with respect to the 0th order light are formed on the bonded surfaces of the parts 1a and 1b. The outer surfaces coming in contact with the air of the parts 1a and 1b are formed as the planes orthognally crossed with the optical axis (z) and the bonded surfaces of the parts 1a and 1b are formed as the planes which are not orthogonally crossed with the optical axis but inclined thereto.  Due to such inclination, a reflection angle obtained in the case of reflecting the 0th order light from a sample surface on the area 2 of the phase plate 1 becomes large, and the light does not enter the visual field of the image formation surface even when it is reflected by a lens group on the sample surface side again, so that the lowering of contrast is restrained to the minimum.

Title: Semiconductor integrated circuit
Inventor: NAKASAKI YASUTAKA
IPC: H01L29/792
Filed: 1980-02-25
Abstract: PURPOSE:To improve stability and precision of a circuit of an IC memory with floating gate type N channel FAMOS, by controlling in a proper way the writing time comparing some of the voltage of the input line to the input voltage. CONSTITUTION:35, 361...36N are MOS devices and 371-37N are n channel FAMOS  devices. As the threshold voltage VTH increases because of the writing in the device  37, so the electric differential V38 increases at the point 38. Therefore comparing  the V38 and the signals from D/A converting part 31, the input is suspended to turn  the FET35 off when the change of the V38 (VTH) reaches the desired value. With such an arrangement, the scattering in the input to the device 37 is completely prevented, so that the operations with high precision and high resolution can be achieved.

Filed: 1989-02-02
Abstract: PURPOSE:To maintain optimum engine power all the time by operating a transfer means to transfer an ideal signal to a pulse generating means from a memory means in response to abnormal frequency when detecting something wrong in a timing signal by a detecting means. CONSTITUTION:A central processing unit 1 calculates each optimum value of ignition timing and injection timing on the basis of data out of various sensors, outputting the timing signal and holding it in a latch 2, and outputs respective ignition and injection pulses to each cylinder from a pulse generating means 3 synchronously with a signal out of a crank angle sensor 4. When a detecting means 7 detects something wrong in the timing signal, a transfer means 5 is selected to the side of a memory means 6, and such an ideal signal, through which prestored optimum ignition and injection are performed, is outputted to the pulse generating means 3 via a latch means 2. Thus, in order to make optimum engine power securable all the time, ignition-injection timing at each cylinder is maintainable.

Title: Magnetic video recording and reproducing device
Inventor: YOSHIOKA ATSUSHI
IPC: H04N5/7826
Filed: 1982-02-17
Abstract: PURPOSE:To obtain a high reproduced-tone quality even if a head height controlling mechanism due to a bimorph plate or the like is omitted and to simplify the device, by using a broad head and recording and reproducing a sound signal on a video track in a VTR of the pilot system. CONSTITUTION:The sound signal is converted to an FM modulation signal with video tracks 12-15 and is multiplexed to a video recording signal and is subjected to time base compression and is digitized and is recorded and reproduced on the extension of the video track. If video tracks 12-15 are used to record and reproduce the sound signal by a video head in this manner, the influence of wow and flutter is reduced considerably, and a broad head 16 where the track width is set to a value wider than the width of recording tracks which are left on a magnetic tape 1 at the recording time is used in the VTR adopting the pilot system. Since the influence of wow and flutter is reduced to a negligible level, the broad head 16 can be used even in the pilot system, and the complication of the device accompanied with the use of a DC high voltage is avoided because special devices for narrow track tracing and special reproducing are unnecessary. The probability of tracking errors is reduced whichever direction the momentary variance comes from.

Title: Polyester sewing yarn
Inventor: SHINOHARA HARUO
IPC: D02G3/46
Filed: 1991-01-22
Abstract: PURPOSE:To obtain polyester sewing yarn having excellent sewing properties in spite of sewing yarn composed of short fibers and small seam shrinkage. CONSTITUTION:Elongation at break of sewing yarn comprising polyester short fibers having >=65mm average fiber length is set <=1.82%, an amount of cutting work done >=7g-cm/denier and sum of dry heat shrinkage percentage at 180 deg.C and residual strain caused by loading under condition of 1g/d load repeated 10 times <=4.2%. Consequently, since sliding resistance of yarn between mutual fibers is large and tenacity utilization of yarn is increased, sewing properties are improved. Further, crystal growth of polyester molecule is increased even by fixed length heat setting at high temperature for many hours, heat shrinkage of twisted yarn during dyeing process can be suppressed and seam shrinkage is lessened.

Abstract: PURPOSE:To obtain the titled resin hollow body having an accute angular part adjacent thereto which is large in the angular part with an even thickness by using a molding with a set of dies each having a core free to slide or sink at a part thereof. CONSTITUTION:When a hollow body (for example, an air spoiler) 4 with two angles 2 and 3 accute sandwitching one side 1 in the section is molded with a thermoplastic resin, a set of dies 7 and 8 having a core 9 free to sink or advance is used at a part of one die 8 and clamped sandwitching a parison 6 extruded from a die head with the core 9 sunk from the surface of the die 8,  which allows the parison 6 to form one accute angular part 2 by extending a  burr 10.

Title: Braking device
Inventor: NISHIWAKI HIRONAO
IPC: B60T7/12
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To keep the sufficient braking force even when a vehicle is stopped on a slope by comprising a first brake holding means for holding the braking force obtained from a foot brake. SOLUTION: When a road is detected an upward slope by, for example, a navigation system 12, the brake is held at stopping. On this occasion, a braking force holding controlling unit 2 outputs a holding signal to an oil pressure/ wire holding unit 3 to keep the braking force when a foot brake 4 is released for starting, which is in danger of the retreating of the vehicle. The oil pressure/ wire holding unit 3 continuously supplies the pressure to a master cylinder from a pressure device mounted in the oil pressure/wire holding unit 3 even when a foot is left or loosen from a foot brake pedal. Whereby the brake can be kept until the predetermined torque is obtained in starting, and the possibility of advancing or retreating of the vehicle can be prevented.
