Title: Gyrocompass
Inventor: KOGURE SHOICHI
IPC: G01C19/38
Filed: 1985-07-12
Abstract: PURPOSE:To enable a gyrocompass mounting correcting operation to be easily performed without using any tool by collating a repeater bearing display in synchronism with a bearing signal from the body of a gyrocompass with a bearing obtained from an astronomical observation. CONSTITUTION:An arithmetic bearing processor 2 arithmetically processes a bearing to be measured with a signal indicative of a bearing obtained from the relative relationship between a rolling ring ball and a liquid tank inputted. Then, an angle setting unit 4 sets the value of a deviation between the bearing to be measured obtained from a repeater compass 6 that conducts the same display as that of a compass card 1a in the first mounting and a true bearing obtained from an astronomical observation to output a deviation setting angle theta. Then, the deviation setting angle theta from the angle setting unit 4 and a bearing phito be measured from the integrator 22 of a bearing processor 2 are inputted and summed by an arithmetic mounting condition correction processor 5 to obtain a corrected bearing phi' taking a compass mounting condition into consideration. Thus, when the mounting condition of a gyrocompass is required to be corrected, a correct bearing can be always obtained by adjusting the setting of the angle setting unit by the quantity of a correction.

Title: Static semiconductor memory device
Inventor: ANDO MANABU
IPC: G11C11/34
Filed: 1985-07-12
Abstract: PURPOSE:To attain the high speed of a reading speed by connecting gates to each other and controlling simultaneously by one signal so as to be temporarily non-conductive by a gate signal formed by responding to the change of an address during reading. CONSTITUTION:One shot signal OS' reaches a minimum value before and after about 35ns from the change of an address and digit line load transistors Q1 and Q2 are respectively temporarily made non-conductive. Since the load transistors Q1 and Q2 are simultaneously made non-conductive and the supply of a current from a power source Vc is broken, the electric potential of the digit line D of a low level side is rapidly lowered toward an earth potential 0V. This lowering is extremely abrupt and the potential difference between the pair of digit lines D and D' is rapidly widened, at a time T1 when the electric potential of a word line W2 completely rises, reaches the potential difference before the change of the address. Thereby, a sense amplifier can rapidly read the contents '0' of a memory cell I2 without delaying the rise of the word line W2.

Filed: 1984-07-24
Abstract: PURPOSE:To observe visually a changing direction of a work by discriminating a correcting direction of a value depending on a tool offset value set newly and a changing value from the preceding value and discriminating the shape of tool from a number of the tool having the set tool offset value. CONSTITUTION:When a keyboard 1 corrects a tool offset value in increasing direction, the amount of change TV in the tool offset value transferred from an input control section 2 to a correction direction discriminating section 3 is positive, the correction direction discriminating section 3 discriminates the correcting direction VD of the tool offset as positive from the sign, a display control section 6 moves a tool 11 drawn in an initial pattern in figure (A) in a direction being parted from the center line 12 as shown in figure (B) and the correcting direction is shown in the arrow 13. In applying correction negatively, in case of an outer diameter tool, the change in the work is displayed as shown in figure (C) as if the work 10 were decreased as shown in crossing line region CLR2 and the arrow 13 representing the correcting direction is displayed. Thus, the change in the work due to reset of the tool offset value is recognized visually and set error is prevented.

Abstract: PURPOSE:To enable to detect a fusing condition of respective fuses even when a memory cell is composed of plural fuses, etc., by rapidly and suitably outputting a write-in condition of the memory cell showing a faulty circuit part. CONSTITUTION:When an input address signal A0, an inversion A0, etc., and address data recorded at ROM in coincidence circuits CMP'0, CMP'1...CMP'n are not coincident, a control line N1 becomes a low level, but, when coincident, the control line N1 becomes a high level, a faulty circuit part is changed over to a redundant circuit part. When memory data of ROM in respective coincidence circuits CMP'0 and CMP'1 are detected, only the input address signal of the coincidence circuits including ROM in which a condition is to be detected, is for example set to a high level, and the address signal inputted to all other comparison circuits, is for example set to a low level. Recording data of ROM, a purpose, are outputted to a detecting line N21. Consequently, the number of test cycles needed to detect a condition of all ROMs becomes n+1, and the contents of ROM can be detected in a short time.

IPC: H04Q1/457
Filed: 1979-11-30
Abstract: PURPOSE:To shorten the operation recovery time of a digital signal receiver by permitting two DFT arithmetic parts to be supplied with the required sampled data at differnt times. CONSTITUTION:By expander EXP1, an 8-bit PCM code inputted to input termial In is converted into a 16-bit linear PCM code, which is sent to two DFT arithmetic parts A and B for arithmetic. When a sampling period is denoted as T, time mT is required for the single arithmetic of either DFT arithmetic part. When DFT arithmetic parts A and B start the arithmetic, they are given time difference mT/2 and selector S7 is changed over at intervals of mT/2 to select arithmetic results of the both by turns and to make them into one. Therefore, the output of the receiver can be obtained at intervals of mT/2 and the operation speed of the receiver is increased.

Title: Electronic watch
Inventor: ASANO KAZUHIRO
IPC: G04G3/00
Filed: 1977-12-22
Abstract: PURPOSE:To maintain the operations such as oscillations or frequency division stable without increasing the power consumption by increasing the gain of the amplifier of an oscillating circuit unit upon the instant reduction in the voltage of a battery, which accompanies the drives of a motor, a lamp, a buzzer and the like. CONSTITUTION:When the output of a pulse composing circuit 3 is at an ''L'' level, the battery voltage is so sufficiently high, when a motor 5 is not driven, that an oscillating circfit 1 and a frequency dividing circuit 2 are operated stably. When motor driving signals are generated from the pulse composing circuit 3, a drive circuit 4 drives the motor 5. At this time, a high current flows to remarkably reduce the battery voltage, but the output of the pulse composing circuit 3 is partially fed back the oscillating circuit 1. As a result, the gain control signals of the oscillating circuit take an ''H'' level, and the gain of the amplifier of the oscillating circuit 1 is so increased that the stable oscillations are continued irrespective of the reduction in the battery voltage. When the drive of the motor 5 is ended, the oscillating circuit 1 continues again its oscillations with the initial low gain.
