Filed: 1989-03-07
Abstract: PURPOSE:To prevent undesirable noises by changing the distance from a magnet provided on the tip of a screw to a magnetoresistance element while adjusting electric resistance value by driving the screw. CONSTITUTION:A magnetoresistance element 1 is provided in the position a little distant from the center of the surface of a substrate 7 of an insulator. Terminals 5 attached to the base 7 and ends of the magnetoresistance element 1 are connected by means of a lead 8. A cover 4 having a screw hole in the center is fixed to the base. Then, the screw 3 having a magnet 2 on its tip is put into the screw hole of the cover 4 and the screw 3 is driven to change a position of the magnet 2 so as to enable the resistance value of the magnetoresistance element 1 to be adjusted to desired value. Thereby, undesirable noises such as additive noises due to contact and abnormal noises due to poor contact can be prevented.

Title: Production of glass
Inventor: NAKAJIMA YOSHIHIRO
IPC: C03C1/00
Filed: 1986-03-13
Abstract: PURPOSE:To obtain large-sized TiO2-SiO2 glass suitable as substrate for IC readily without causing cracks, etc., by blending silica sol with a titanium- containing solution, adjusting the blend to proper pH, gelatinizing the blend, drying and sintering the gel. CONSTITUTION:An alkyl silicate is hydrolyzed to give a hydrolyzed solution, which is blended with silica to synthesize silica sol. Then, the silica sol is mixed with a titanium-containing solution separately synthesized. Then, the mixed solution is adjusted to about pH 4, gelatinized and the prepared gel is dried and sintered to give the aimed TiO2-SiO2 glass. Consequently, large-sized glass containing titanium oxide can be obtained by lower temperature treatment than a conventional method. Since prepared TiO2-SiO2 glass has smaller expansion and contraction caused by heat than quartz glass has, it is preferably used as substrates for IC for raising integration degree, telescope having large aperture, etc.

IPC: G03B5/00
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent the shake and the transmission loss of a transmission gear transmitting driving force to a zoom lens barrel. SOLUTION: The transmission gear 28 is housed in the aperture 21 of a fixed barrel 15 and a shaft 30 is supported by bearing parts 26a and 26b and the hole 34 of a camera main body 10. Thus, since a load imposed on the bearing parts 26a and 26b is reduced and deflection or the like is not generated because of the high rigidity of the main body 10, the shake of the gear 28 is suppressed. Besides, a gap between the gear 28 and an output gear in a gear box 37 can be accurately decided.

Title: Frame synchronization circuit
Inventor: MORIKAWA HISASHI
IPC: H04J3/06
Filed: 1990-03-07
Abstract: PURPOSE:To detect erroneous frame synchronization by counting a frame pulse when a frame pattern dissidence detection signal is generated, converting the count till a frame synchronization release signal is generated into a backward protection stage number and giving the result to a frame synchronization establishment protection circuit. CONSTITUTION:A protection stage number control circuit 4 receiving a frame pattern dissidence detection signal together with other signal counts a frame pulse by receiving a frame pulse generated from a frame pulse generating circuit 3 for each frame period based on the clock. Since a frame synchronization release state signal is outputted from a frame synchronization release protection circuit 1 after lapse of processing of a prescribed protection stage number, the protection stage number control circuit 4 stops the count of the frame pulse by using the frame synchronization release state signal, and converts the count so far into a backward protection stage number and gives it to a frame synchronization release protection circuit 2. Thus, erroneous frame synchronization establishment is prevented.

IPC: G11B20/18
Filed: 1992-02-06
Abstract: PURPOSE:To efficiently perform lost corrections by providing a prohibitive pattern detecting means and a position information storage means and reducing the number of data bytes assumed to be lost. CONSTITUTION:In a demodulating circuit 10, the data, which are read, are demodulated from (2, 7) RLL modulated signals to NRZ signals and outputted to an error.lost correcting circuit 40. A prohibitive pattern detecting circuit 20 makes three specific kinds as the prohibitive patterns, sends lost position signals to an error position information storage section 30 during a detection period and a flag is established at the position. In the circuit 40, a storage section 41 stores the NRZ signals as a data series, a syndrome arithmetic section 43 performs computations based on the data series and a Galois field origin generating section 44 generates the Galois origin which corresponds to the lost data position. A Galois field arithmetic section 42 obtains a correction syndrome polynomial corresponds to the data series from these inputs. A correction executing section 45 generates corrected data from the polynomial. The circuit 40 only performs error corrections if there is no position information. Having this constitution, the amount of data assumed to be lost is reduced.

Title: Artificial fault generating system for information processor
Inventor: NAGASAWA TOSHIKATSU
IPC: G06F11/22
Filed: 1988-03-11
Abstract: PURPOSE:To simplify the evaluation of an artificial fault of an intermittent fault by constituting the title system so that the artificial fault can be generated from an arbitrary address of a microprogram. CONSTITUTION:A data signal is transferred to a register 8 from a register 7 through a signal line 106. Also, in the same way, a parity signal is transferred through a signal line 107, a selecting part 9 and a signal line 108. Subsequently, the normality of a parity is tested by a parity check circuit 10. However, when a flip-flop (FF) 1 and an FF 6 are both logic '1', the selecting circuit 9 is switched and a parity part PA of the data register 7 is brought to bit inversion by an inverting circuit 12, and thereafter, set to a parity part PB of the data register 8 through the selecting part 9. The parity check circuit 10 detects a parity illegality of the data register 8 by signal lines 109, 110. When the parity illegality is detected, it is informed to a service processor by a signal line 114, and simultaneously, the FFs 1, 6 are set to a logic '0' level.
