Title: Bus interrupting device
Inventor: TERADA MATSUAKI
IPC: G06F13/24
Filed: 1981-06-15
Abstract: PURPOSE:To reserve interruption by inhibiting the generation of a device selecting signal from a processing device to a device selection request from an I/O device instead of an unconditional output of an acceptable signal for an interrupt request from the I/O device. CONSTITUTION:Plural processing devices 1 are connected to a maltiplexer (MPX) 6 and I/O devices 3 are connected to a bus 2 connected to the MPX6. After receiving an interrupt request signal RQ1 from an I/O device 3, the MPX6 sends an interrupt acceptable ACI signal to the bus 2. In response to the signal, an I/O device 3 turns on a device selection request signal SL1 but the interrupt is reserved by interrupting the device selection from a processing device 1 for the SL1. Thus, interrupt requests from plural I/O devices connected to one bus can be selectively received in every I/O device without the specific connection of an interrupt request line and an interrupt permitting line in every I/O device.

Title: Acoustic system on vehicle
Inventor: MOTOJIMA AKIRA
IPC: H04R3/12
Filed: 1995-04-17
Abstract: PURPOSE: To hear sounds, which are selected from plural sound sources by a speaker only for each seat and a signal matrix switch which are provided in the vicinity of the head part of the seat in an automobile compartment, without being disturbed by sounds from speakers of another seats. CONSTITUTION: Acoustic signals which individual passengers arbitrarily select from plural sound sources 11 to 16 by a matrix switch 21 are supplied to speakers 61a to 61d only for seats provided in vicinities of head parts of respective seats through equalizers 31, sound volume adjusters 41, and amplifiers 51. The sound source of a passenger is very close to his ears, and sound sources of adjacent seats are intercepted by seats and have a high distance ratio and the attenuation effect is large. As the result, each passenger is not disturbed by sounds of another seats even if passengers select different sound sources. Since it is difficult to reproduce the low-pitched sound part by speakers in head parts of seats, speakers 62 only for low-pitched sound are provided.  With respect to the low-pitched sound part, one sound source is selected by a selector 81 in accordance with preliminarily determined precedence, for example, in the order from the largest low-pitched sound effect.

Abstract: PURPOSE:To reduce collector junction capacitance, and enable a fine formation, by arranging a collector leading-out electrode, via a first insulating film on a semiconductor substrate, forming a base leading-out electrode, via a second insulating film on a collector leading out electrode, and arranging an emitter layer on a polycrystalline base layer. CONSTITUTION:The following are arranged; a collector leading-out electrode 33 composed of a silicon substrate 31, an N-type collector layer 32 and an N-type doped polycrystalline silicon film, a base leading-out electrode 35 composed of a P-type base layer 34, a P<+> type doped polycrystalline silicon film, an N<+> type emitter layer 36, a collector contact electrode 37, a base electrode 38, an emitter electrode 39, an SiO2 film (a first insulating film) 41, an SiO2 film (second insulating film) 42 and an SiO2 film 43. This structure forms the N-type collector layer 52 whose area is small and limited to a necessary value. Being in contact with the layer 32, the collector leading-out electrode 33 composed of an N<+> type doped polycrystalline silicon film is formed. Without interposing a silicon crystal film, the length of the electrode 38 can be reduced, thereby decreasing the junction capacitance.

Abstract: PROBLEM TO BE SOLVED: To provide a simple method for selectively recovering salt components and capable of obtaining directly usable salts in high yield from waste salts containing nitrates, nitrites and hydroxides generated during a heat treatment of steel parts in a salt bath by carrying out a specific means. SOLUTION: The subject method is to dissolve waste salts in water, separate insoluble residues and fractionally crystallize alkali nitrates. The solid waste salt is crushed to 1-50mm granule size and dissolved in a solution containing hydrogen peroxide acidified by nitric acid at 40-90 deg.C. Insoluble residues are filtered and the concentrated solution is neutralized and cooled to -10-+20 deg.C to precipitate potassium nitrate. The solution is concentrated at 60-120 deg.C to crystallize sodium chloride. Sodium nitrate is crystallized by adding concentrated nitric acid to the residual solution. Advantageously barium possibly present in a weak alkaline medium is precipitated and separated as barium carbonate by adding carbonate and an alkali after dissolving the waste salts.

Title: Static ram
Inventor: MIYAOKA SHUICHI
IPC: G11C11/413
Filed: 1986-04-23
Abstract: PURPOSE:To improve the resistance to alpha-ray intensity by turning usually on one of P-channel load MOSFETs connected in parallel as a load circuit of a data line and turning off the other at the write operation to increase the information charge quantity stored in a gate capacitance of the said MOSFETs. CONSTITUTION:The size of load MOSFETs Q9-Q12 is formed comparatively larger to provide comparatively large conductance. The high level of a write signal WE brings the P-channel MOSFETs Q9-Q12 into the OFF-state. Since only MOSFETs Q5-Q8 having comparatively small conductance are connected to a complementary data line, the potential of the complementary data line is brought into a large signal amplitude according to a write signal. As soon as the write operation is finished, the write signal WE is changed into a low level, the load MOSFETs Q9-Q12 are turned on to reset the write signal at a high speed.

It is polymerized and assimilated through a second volatilizing part 9 and a second activating light throwing part 10, and the strand is taken up around a take-up drum 13. Thus, a fiber is obtained where the refractive index distribution is set with a high precision in accordance with the purpose.

Abstract: PURPOSE:To detect the turning direction of a slewing base table by information from a rotary encoder by using two rotary encoders of a low frequency. CONSTITUTION:Two rotary encoders 10a and 10b to detect the turning angle of a slewing base 2 are set and connected to the slewing base 2 in an interlocking manner such that pulse signals sig.1 and sig.2 to be sent out with the turning operation are sent out with nearly equal pulse width W and a pulse repeating period T and also such that the phases of the signals sig.1 and sig.2 are differentiated from each other with a smaller width than the pulse width W. On the basis of the leading and trailing detection of the signals sig.1 and sig.2, the turning direction of the slewing base table 2 is judged and pulse signals of pulse repeating frequency (f=1/T) four times greater than pulse from the encoders 10a and 10b is sent out from a circuit 15. Since inexpensive rotary encoders of low frequency are used, the turning angle detector of high detection accuracy can be obtained at low cost.
