Title: Semiconductor photo detecting element
Inventor: TORIKAI TOSHITAKA
IPC: H01L31/103
Filed: 1983-02-03
Abstract: PURPOSE:To reduce the capacitance and thus enable high speed response by forming the second conductivity type impurity doped region between high concentration conductive regions of the first and second conductivities formed in opposition in comb teeth form at a fixed period. CONSTITUTION:After forming an N type InGaAs layer 2 on a semi-insulation InP substrate 1, a high concentration N<+> layer 3 and a high concentration P<+> layer 4 are so formed as to be opposed to each other. Next, the P-type conductive layer 5 is formed in comb teeth form between the layers 3 and 4. In this case, the layer 5 is formed with the period of (d) which satisfies the formula. In the formula, simbols epsilonO and epsilonS represent vacuum dielectric constant and semiconductor specific dielectric constant, respectively; N1 and N2 the carrier concentration of the layer 3 and that of the layer 5, respectively; V a reverse bias impressed voltage, and q a unit charge. When thus constructed, since depletion advances from the interface between the N layer 2 and the P layer 5, it is possible to deplete completely a photo receiving part between the layers 3 and 4 by a low impressed voltage. Accordingly, the capacitance in the case of complete depletion becomes sufficiently small, and then higher speed response is enabled.

Title: Energy storing apparatus
Inventor: YONEDA OSAMU
IPC: H02J15/00
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To improve the energy converting efficiency of an energy storing apparatus by forming a core of its generator-motor of an axial type winding mode out of a layered product comprising magnetic thin plates, and by disposing the core to extend in parallel with the rotational axis of its inertial mass body. SOLUTION: Making a core 23 out of strip thin plates laminated in the form of concentric circles in its radial direction, it is disposed adhesively to the bottom surface of a coil board 22 to be extended in parallel with a rotational axis K-K direction. Also, a three-phase coil is set facing opposite to a permanent agent in the direction of the rotational axis K-K with a small gap in between. When feeding electric energy to a generator-motor 20, a rotating magnetical field in parallel with the rotational axis K-K is formed by the three- phase coil. This rotating magnetic field acts on the magnetic field generated by the permanent magnet attached to a fly wheel 6, and the fly wheel 6 rotates around in the rotational axis line K-K direction. As a result, even after the feed of the electric energy to the three phase coil is stopped, the fly wheel 6 continues its rotation to store the electric energy in an energy storing apparatus 1 in the form of a kinetic energy.

Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To confirm the motion of a product when producing it or at other cases while monitoring an illegal act against a game machine in cooperation with a game machine-monitoring network. SOLUTION: When an electric source is connected to a NW board 30, the flag F value alloted to a specified address of an EEPROM 30Af is read out (S100), and it is discriminated (step S102) whether the read-out value is '1' and a timer T is actuated (S104). After the elapse of 10 min. in the timer T, security is checked (S200), and then, a network function is actuated (S300) through the NW board 30. In this way, the routin is finalized. When it is judged that 10 min. has elapsed, the counter C of EEPROM is counted up (S 08) and it is discriminated whether the value of C is 3 or more (S110) and when it gets to 3 or more, the value of F is set at '1' (S112). In this way, the security check is released only 10 min. interval after the electric source has been connected until the number of connection times with the electric source to the NW board gets to 3 or more.

Title: Dielectric ceramic composition for high frequency

IPC: C04B35/495
Filed: 1989-01-27
Abstract: PURPOSE:To obtain a ceramic composition made it possible to control tempera ture coefficient of resonance frequency in good reproducibility while maintaining high Q value by preparing a Ba-Zn-Ta-O-ZrO3 based composition having a specific composition. CONSTITUTION:The dielectric ceramic compacting expressed by formula I, being within the range expressed by the equation 0.004<=y<=0.013 and having replacing amount x in formula II represented by the equation 0<=x<=0.06. In the formula I, y value expressed by the equation 0.004<=y<=0.013 means that an amount of Ba is reduced slightly less than that of stoichiometric composition, because regular arrangement of Zn and Ta which are B site ions in perovskite structure is produced in a short time by reducing the amount of Ba and suffi cient burning can be carried out in a burning process at high temperature for a short time. Furthermore, y value must be limited to the above-mentioned range, because when y is <=0.004, the composition becomes close to stoichiometric composition and made sintering difficult and when y exceeds 0.013, dielectric characteristic, especially Q value is lowered.
