Patent JP-S6194293-A (JP)
Title: Semiconductor memory circuit
Inventor: AKIYAMA MITSUKO
IPC: G11C11/34
Filed: 1984-10-16
Abstract: PURPOSE:To increase both the working speed and the capacity of a semiconduc tor memory circuit by producing forcibly the drop of the reference voltage of a conventional memory circuit to secure a level between the high voltage and the low voltage of a signal at all times and therefore preventing the malfunctions without increasing the signal amplitude. CONSTITUTION:The reference voltage is supplied from the same side as the supply side of a word selection signal, and constant current sources IR1 and IR2 are connected to the end of a reference line which is wired from the supply side. Therefore both currents IR1 and IR2 flow through the reference line and induce the voltage drop due to wiring resistances R'11, R'2.1-R'1,m-1 and R'2,m-1. The levels of the sources IR1 and IR2 are selected so as to secure the coincidence the voltage drop of the reference line and that of a word line. Thus the reference voltage VREF is always set at about a middle level between the High voltage VH and the Low voltage VL. Then the constants of a memory cell can be detected accurately.

IPC: G10K15/04
Filed: 1987-08-31
Abstract: PURPOSE: To faithfully reproduce a sounding body which has dynamic characteristics by composing a synthesized sound signal of a modulated sound signal and a corrected sound signal. CONSTITUTION: A sound characteristic values which is inputted from an input terminal 1 is stored, and a sound control signal is generated by a storage arithmetic part 2 from the sound characteristic value according to a sounding body state indication signal and outputted to a sound reproduction part 30. In the sound reproduction part 3, a reproduction control part 30 calculates a frequency and a sound pressure level correction coefficient according to the sound control signal, inputs a specific sampling signal among sampling signals of individual sound sources stored in a sound memory part 31 to a correction reproduction part 32, and corrects the signal with a correction coefficient, thereby outputting a corrected sound signal to the sound correction part 3.  Corrected sound signals outputted by plural sound reproduction parts 3 are modulated by a modulation part 4 when necessary and outputted as modulated sound signal, and a synthesis part 5 puts the modulated sound signal and corrected sound signals together and output a synthesized sound signal. Consequently, the sound of the sounding body can be represented faithfully.

Title: Cell missing prevention control system
Inventor: ADACHI MAKOTO
IPC: H04L47/43
Filed: 1993-09-01
Abstract: PURPOSE:To prevent cell missing by reading the same cell repetitively and sending the read cell till a timing signal is set normal when the timing signal is inputted while reading of one cell is not finished. CONSTITUTION:A read end detection section 4 provides a signal to a control section 3 when the reading of one cell from a memory 1 based on an address signal from an address generating section 2 is finished. When the read end signal is not inputted and a succeeding timing is received, the control section 3 loads a same head address as that of a preceding signal to the address generating section 2 and read control of the same cell is made again and the same cell is read repetitively and sent. Thus, missing of a read cell due to disturbance of a timing signal is prevented.

Abstract: PURPOSE: To provide a proton-conductive polymer solid electrolyte made of a specific polyether netted by a hardener, that has a high ion conductivity at room temperature and has good mechanical properties, by introducing an acid into the netted polyether. CONSTITUTION: A proton-conductive polymer solid electrode, comprising a polyether which is netted by a hardener containing two epoxy functional groups and which contains two first amine terminal functional groups, has an acid introduced into the netted polyether. The acid is selected from among inorganic acid, organic acid and polyacid that include -COOH functional group, organic acid and polyacid that include -SO3 H functional group, and their mixture. If the amount of acid in the electrolyte is too small, conductivity is insufficient. If the solubility of the acid in the polymer is limited, the weight ratio of the acid is 5-50%. The proportion of the acid becomes too much, and either the product becomes unstable or solubilization becomes very difficult.

Title: Automatic sampler
Inventor: KUROISHI TADAFUMI
IPC: G01N35/10
Filed: 1985-10-02
Abstract: PURPOSE:To achieve a higher measuring reproducibility and a determination accuracy with a higher sampling accuracy, by sampling a sample after a gas equal to the sampling amount is injected into a sample container with a microsyringe. CONSTITUTION:The position of a piston rod 7 is set at the position of the sampling amount while a microsyringe 4 is moved by a motor 6 with air filling the syringe 4 to insert a needle 10 into a sample container 11 through a rubber cock 12. The tip of the needle 10 is stopped at the position of an air layer 14 of the container 11 to force the air in the syringe 4 out with the piston rod 7. Then, after the tip of the needle 10 is stuck into the sample 13 with the motor 6, the rod 7 is driven with the motor 9 to sample a fixed amount of a sample. This prevents a negative pressure in the container 11 when a sample is sampled to improve the sampling accuracy, resulting in a higher measuring reproducibility, determination accuracy and the like.

Inventor: ABE YOSHIYUKI
IPC: F24F1/00
Filed: 1990-08-20
Abstract: PURPOSE:To obtain a blowing unit with no rotating parts, by blowing a gas through utilizing corona discharge. CONSTITUTION:A pair of shield plates 1, 1 constitute a gas passage, which is provided with a gas inlet port 1a at one end thereof and with a gas outlet port 16 at the other end. A conductive wire 2 is disposed between the pair of shield plates 1 in an electrically insulated condition. A grid-form sheet 3, permeable to gases, is disposed on the gas outlet port 1b side of the pair of shield plates 1, in the condition of being electrically insulated from the wire 2. When a high voltage of about 5-6kV is applied to the wire 2 from an external high-voltage power supply 4 to cause corona discharge, the discharge develops toward the grid-form sheet 3, releasing positive ions. Because the gas inlet port 1a between the pair of shield plates 1, 1 is opened, the corona discharge draws air through the inlet port la to the space between the pair of shield plates 1, 1, resulting in an air flow in the direction from A to B. This is utilized as a blowing unit.

Abstract: PURPOSE:To measure correctly by providing an ultrasonic wave sending element within a vortex generating column, and ultrasonic wave receiving elements at the downstream side of the vortex generating column in symmetric relation to a conduit. CONSTITUTION:A vortex generating column 22 is fixed within a conduit 23, having an ultrasonic wave generating element 24. Moreover, two ultrasonic wave receiving elements 25, 26 are provided in symmetric relation to an inner wall of the conduit 23 at the downstream side of the vortex generating column 22. When a fluid starts flowing in the conduit 23, a von Karman's vortex street 29 is generated at the downstream side of the vortex generating column 22. At this time, when an ultrasonic wave is sent into the conduit 23 from the ultrasonic wave generating element 24 driven by an oscillating circuit 27, the ultrasonic wave is propagated in the fluid and modulated alternatingly by the von Karman's vortex street 29, and detected by the receiving elements 25, 26. The alternatingly modulated signal is demodulated to a vortex frequency by a demodulating circuit 28 and output. Accordingly, the flow rate of the fluid running in the conduit 23 can be correctly measured.
