Filed: 1986-09-16
Abstract: PURPOSE:To execute a branch opposite instruction without having waiting the definition of a branch opposite real address in a branch instruction, by holding the branch opposite address of a branch history table as a real address. CONSTITUTION:The complementary instruction pre-fetching of an instruction pre-fetching buffer 1 is performed in such a way that an address adder 6 performs a various kinds of address modification based on a bit of address information from a pre-fetching instruction controller 5, and generates the virtual address of an instruction, and supplies it to a virtual address register 7. A branch opposite estimating buffer 9 performs retrieval based on the virtual address, and when the same virtual address is found the real address corresponding to the address is sent to an instruction buffer counter 3 and the adder 6, and a bit of virtual address generating information, to the adder 6. The adder 6 generates the pre-fetching address of the branch opposite instruction estimated based on those two pieces of information, and sends it from the register 7 to a memory device 10. In this way, a purpose can be attained.

Title: Viscous material emitting apparatus
Inventor: NAKAYAMA YOSHIMITSU
IPC: B05C5/00
Filed: 1986-09-16
Abstract: PURPOSE:To easily control emitting quantity by making the residual quantity of a viscous material always constant, by providing the air cut nozzle opened to the inner wall of the emitting port of the viscous material and blowing off air from the nozzle after the finish of the extrusion of the viscous material. CONSTITUTION:A putty material having high specific gravity is used in the correction of unbalance as a viscous material for correction and the viscous material 41 is extruded toward an emitting port 12 by the operation of a pump part 13 for the time proportional to unbalance quantity. When the rotation of a geared motor 16 through a drive circuit 31 is finished, a timer part 33 outputs a signal for operating an air valve 22 to a valve driving circuit 34 after the elapse of a definite short time. The air passing an air pipe 21 and blowing off from an air cut nozzle 11 allows the viscous material accumulated in the emitting port 12 or on the surface thereof to fall and, therefore, the remaining way of the viscous material becomes an almost constant state every time and the accuracy of emitting amount is enhanced.

Title: Plural-image synthesizing and projecting device
Inventor: IWAKI TADAO
IPC: H04N5/74
Filed: 1993-09-02
Abstract: PURPOSE:To project a high-precision image without joint by projecting a synthesized image on a projecting surface by an image forming optical system after projected light obtained by the light emission of plural picture display means is optically synthesized to be one image. CONSTITUTION:Light emitted from a white light source 1 such as a xenon lamp is converted into nearly parallel luminous flux by the illumination lens 2 of a condenser lens and irradiates 1st and 2nd TFT liquid crystal displays 4a and 4b. At such a time, an irradiating luminous flux area is limited by using a light shielding mask 3 so that the irradiating luminous flux may irradiate only the picture displayed part of the displays 4a and 4b. Thus, the picture displayed on the displays is read out by irradiating luminous flux transmitted through the displays 4a and 4b as an optical image having light intensity distribution. Parallel prisms 5a and 5b functioning as an image synthesizing optical system synthesize the optical image as one image and the synthesized image is projected on a screen 7 by an image forming lens 6.

Title: Derailment decision method for automatic guided vehicle
Inventor: SAKAIRI NATSUHIKO
IPC: G05D1/02
Filed: 1990-08-20
Abstract: PURPOSE:To surely output a derailment decision signal even when a detector is faulty by deciding the presence or absence of a pattern similar to a definite pattern signal to be caused in the detector when an automatic guided vehicle travels on a guiding marker band. CONSTITUTION:Signals detected by the detectors 1a, 1b are amplified respectively by amplification circuits 2a, 2b, and the difference signal (b) of the difference of two signals is detected by a differential amplifier 3. The signal (a) of an oscillation circuit 5 is superposed on the difference signal (b) by an addition circuit 6, and the steering signal A of the automatic guided vehicle is outputted, and the automatic guided vehicle is steered by the steering signal A while being vibrated by this signal (a). On the other hand, the signal (a) is taken out from the difference signal (b) through a filter 7 to take out the same frequency as the signal (a), and is turned into a DC signal by a rectification circuit 8. After that, this DC signal is compared with reference voltage 9 by a comparator 10, and in case that the similar pattern is included, the automatically guided vehicle is decided to travel normally, and in the case below a definite level, the automatic guided vehicle is decided to be derailed, and the comparator 10 outputs a derailment signal B. Thus, even at the time of the fault of the detector, the derailment decision signal can be surely outputted.

Filed: 1982-12-13
Abstract: PURPOSE:To monitor the presence or absence of modulation and a transmission level by multiplexing a part of a TV signal, detecting the level and discriminating the transmission level to measure automatically the TV signal. CONSTITUTION:A TV signal from an input terminal 12 is frequency-converted by a converter 1 and transmitted to a monitor terminal 13. The converter 1 receives a selecting signal from a main board 3 including a computer by an input signal from the keyboard 9 and performs frequency conversion of the TV signal as to a prescribed channel via a PLL circuit 2. The signal of one channel frequency- converted is divided into fV, fA at an fv/fA multiplexing filter 4, the signal fv is converted into an analog level by an fv level detector 6 and the presence or absence of modulation is checked by an AM detector 10. Two signals converted into an analog level are converted digitally at A/D converters 7, 8, compared with a reference value at the main board 3 and whether or not the signal level is a specified level is discriminated.

Respective differences between the coils 9081, 9082 and between the coils 9091, 9092 are added by an adder 19 and a phase having the same phase as an excited sine wave is subtracted from the added value by the adder 19 through a phase adjusting means 16 to obtain a sine wave whose phase is shifted from the excited sine wave by the rotational angle of the resolver. The phase difference is measured by a phase difference counter 23 through comparator 21, 22 to use it as a commutation control signal and the period of an output from the comparator 22 is measured by a period counter 24 to calculate a rotating position.
