Title: Ink dot printer
Inventor: NAKAYAMA TETSUO
IPC: B41J2/305
Filed: 1985-02-28
Abstract: PURPOSE:To prevent the generation of spark discharge to permit stable printing, by a method wherein a gland is made on the printing head side and also negative voltage is applied on the opposed electrode thereof so as to generate potential difference sufficient to fly ink over the space between the opposed electrode and printing elements. CONSTITUTION:An ink 9 in an ink tank 10 is held by surface tention on the tip ends of printing elements 12 through the gaps between through holes 11 and printing elements 12. When a drive portion 13 moves forward the printing elements 12, the gap between the printing elements 12 and an opposed electrode 7 becomes smaller. As a result, the ink 9 creeping around the tip ends of the printing elements 12 is pulled by the opposed electrode 7 with Coulomb's force and flys over to form dots on a recording sheet. On the other hand, as potential difference is generated between the opposed band-plate-shaped electrode 7 and the printing elements 12 by applying negative voltage to the opposed electrode 7, the critical point of generating spark discharge rises and the potential difference between the both members becomes large, which allows the effective ink fly to be ensured.

IPC: G06F17/14
Filed: 1983-03-09
Abstract: PURPOSE:To perform fast Fourier transform arithmetic through an arithmetic circuit of simple constitution regardless of variation in the number of points of the arithmetic circuit by using selectors and a shift register which are standard logical circuits for address generation. CONSTITUTION:When 16-point fast Fourier transform FFT arithmetic is performed, a counter 1a supplies outputs 4a, 4b, 4c, and 4d of bits 2<0>, 2<1>, 2<2>, and 2<3> to selectors 9a, 9b, 9c, and 9d. The shift register 8, on the other hand, generates control outputs 10a, 10b, and 10c of bits 2<0>, 2<1>, and 2<2> for controlling selectors 9a-9d. The outputs 10a-10c of the register 8 are ''0'' in a pass 1 of the FFT arithmetic and the selectors 9a-9d select counter outputs 4b-4d, and 4a to obtain an output 6a. Then, the outputs of the register 8 are ''1'', ''0'', and ''0'' in a pass 2 and the selectors 9a-9d select the counter outputs 4b-4d, and 4a to obtain an output 6b. Similarly, outputs 6c and 6d are obtained from the selectors 9c and 9d.

Title: Input breaking circuit of monitor and control signal
Inventor: YAMAGUCHI KAZUO
IPC: H04B17/40
Filed: 1984-03-02
Abstract: PURPOSE:To prevent malfunction of a monitor and control circuit due to a service signal by providing the input part of the monitor and control circuit with a gate which cuts off the input of the monitor and control circuit when a monitor and control signal is not inputted. CONSTITUTION:While the service signal is supplied to up and down transmission lines, the output of a signal break detecting circuit 5-3 in a down repeater is in the low level, and a gate 7-6 is closed. Consequently, the service signal output of an up repeater receiving part 2-1 cannot pass the gate 7-6, and frequency components of the monitor and control signal are not applied to a monitor and control part 7-3 through a monitor filter 7-2 even if these frequency components are included in the service signal, and therefore, malfunction of a monitor and control circuit 7 is not caused during service. If troubles occur on a transmission line, the service signal is turned off, and the monitor and control signal is supplied from a transmitting part 1 of a terminal station A to the up transmission line. Thereafter, loop back transmission lines are formed successively in individual repeating stations to perform test, thereby discriminating faulty positions.

Title: Inside-cylinder pressure detector for internal combustion engine
Inventor: IWATA TOSHIO
IPC: G01L23/10
Filed: 1988-02-22
Abstract: PURPOSE:To stabilize pressure signals by providing a current-voltage converting function element in a piezo-electric type inside-cylinder pressure sensor. CONSTITUTION:The pressure-electric charge quantity converting factor of a piezo-electric type inside-cylinder pressure sensor 1 has a positive temperature characteristic and, when the temperature rises, the quantity of the electric charge outputted from the sensor 1 increases and correction is required to the temperature change in order to obtain correct inside-cylinder pressure values. Therefore, a thermistor 6 is assembled in the sensor 1. When the thermistor 6 is assemble in the sensor 6 as part of the feedback resistance of an operational amplifier 51 so that a change in the resistance value caused by the temperature change of the thermistor 6 can immediately change the current-voltage converting factor, the sum of the resistance values of a resistance 53 and the thermistor 6 becomes smaller because of the change in the resistance value of the thermistor 6, even when the temperature of the sensor 1 rises and the quantity of its output electric charge increases and, as a result, the output signal of the amplifier 51 tends to become larger. Therefore, stable inside-cylinder pressure signals can be obtained always regardless of the temperature change of the sensor 1.

IPC: H01L21/338
Filed: 1989-02-20
Abstract: PURPOSE:To markedly improve controllability and reduce surface irregularity of threshold voltage by adding a process wherein hydrogen atom is diffused from a gate electrode forming part position. CONSTITUTION:At the time of forming an operating layer 3, the concentration thereof is set comparatively high; before a gate electrode 9 is formed, ECR hydrogen plasma processing or high frequency plasma processing is performed; thereby diffusing hydrogen atom from a gate electrode forming part position into the operating layer 3. Hence the carrier concentration in the vicinity of a substrate 1 surface can be reduced to the carrier concentration excellent in breakdown voltage. In addition, the diffusion amount of hydrogen atom is reduced from the above part position toward ohmic regions 6a, 6b, that is, the inactive amount of donar is reduced. As the result, between the ohmic regions 6a, 6b and the above part position, an inclined distribution of carrier concentration (carrier concentration distribution increasing toward the ohmic regions 6a, 6b) can be obtained. Thereby surface irregularity of threshold voltage can be reduced.
