Title: Toner residual detector
Inventor: KAWAMORI ZENZO
IPC: G01N27/02
Filed: 1988-05-09
Abstract: PURPOSE:To accurately detect only toner residual in a developing tank by detecting the variation of impedance between a conductor and an electrode and detecting that the toner residual becomes under an allowable value based on the variation. CONSTITUTION:An AC voltage is put on a developing sleeve (conductor) 2 and a stirring shaft 9 is driven to be rotated at a constant speed in order to change a distance between stirring blades (electrode) 10a and 10b and the developing sleeve 2 periodically. The impedance between the stirring blades 10a and 10b and the developing sleeve is changed with charges induced to the stirring blade 10a or 10b and a voltage signal accompaniedd with said change is inputted in a low pass filter 14 through a buffer 13. When it is detected that the value of a toner level output signal from a peak hold circuit 17 lowers to a specified value or less, it can be detected that the toner residual in the developing tank 1 is remarkably decreased. Thus, the toner residual can be accurately detected without receiving the effect of the length of a wire.

Title: Bump structure, printed wiring board and manufacture thereof
IPC: H01L21/60
Filed: 1992-04-03
Abstract: PURPOSE:To enhance the reliability of the junction step by a method wherein a bump is composed of the resin filled up in a through hole and a conductive layer coating the protection from the surface of a double-sided wiring board to be hardly collapsed thereby enabling even the level to be maintained relieving the strain (stress) after finishing the junction step. CONSTITUTION:The upper part of a filled up part 14a is protruded from a substrate 17 simultaneously with filling up a blind via hole 15 formed on a double-sided wiring board 11 with a resin 14. Next, a bump 13 basically as a double layer structure comprising the protrusion 4b as an inner layer and a plating layer 21 coating the protrusion 4b as an outer layer is provided. This bump 13 notably different from any conventional metallic bump, protrusively leaving the resin part 14b of a prepreg 14 on the blind via hole 15 gives sufficient strength during the junction step with an IC chip to be hardly collapsed. On the other hand, the protrusion amount of the resin part 14b is almost equivalent to the thickness of another plating layer 22 to be 5-30mum e.g. 20mum suffices for the protrusion amount.

Filed: 1984-05-31
Abstract: PURPOSE:To improve response, by a method wherein, in automatic transmission gear for a hydraulically-driven car, a fluctuation in a load is detected by means of the pressure of a transmission and is utilized as a parameter adapted to provide an automatic transmission signal. CONSTITUTION:Computation of automatic transmission is effected through control of the capacities of hydraulic pumps 11 and 12 by means of signals from oil pressure sensors 28 and 29 which respectively generate a signal responding to an internal oil pressure in each of 2 oil pressure pipings 13a and 13b through which the pumps 11 and 12 are interconnected. A deviation between the set number of revolutions and the number of revolutions of an engine is decided to provide an automatic transmission signal. Thus, a change in the pressure of transmission working oil is utilized as a parameter adapted to provide an automatic transmission signal, and this enables increasing of response to a fluctuation in a load.

Title: Bistable optical circuit
Inventor: INOUE YASUSHI
IPC: G02F3/02
Filed: 1989-05-02
Abstract: PURPOSE:To obtain bistability between the frequency of input light and the frequency of output light by utilizing the light frequency-light intensity bistability of a nonlinear Fabri-Perot resonator and the input light intensity-output light frequency conversion characteristic of a single oscillation semiconductor laser. CONSTITUTION:The structure parameters of the nonlinear Fabri-Perot resonator 11 are so set that the bistability is obtained between the frequency of the light L1 and the output light L2. The single oscillation semiconductor laser 12 oscillates with single wavelength and varies in oscillation frequency according to the input of the output light L2 of the nonlinear Fabri-Perot resonator 11 to output light L3 based upon the frequency variation. Namely, the single oscillation semiconductor laser 12 has the input light intensity-output light frequency conversion characteristic. Thus, it is evident from the relation between the frequency of the input light L1 to the nonlinear Fabri-Perot resonator 11 and the frequency of the output light L3 of the single oscillation semiconductor laser 12 that the bistability is present between the input light frequency and output frequency.

Title: Semiconductor device
Inventor: HAYANO TETSUKAZU
IPC: H01L27/082
Filed: 1985-05-25
Abstract: PURPOSE:To prevent an abnormal phenomenon from generating in the voltage- current characteristics of the P-N-P transistor Tr by a method wherein the region of the N<+> buried layer for the N-P-N transistor Tr is extended up to just under a part of the collector region of the P-N-P transistor Tr or up to just under the emitter region thereof. CONSTITUTION:The region of an N<+> buried layer 3a is extended up to just under a part of the collector region 9 of a P-N-P transistor Tr or up to just under the emitter region 8 thereof. By extending a region of the substrate, wherein an N<+> diffusion is performed before the epitaxial growth process, the region of the layer 3a can be extended to an arbitrary place. By forming the layer 3a in such a way, the collector-emitter voltage of the P-N-P Tr grows. In that case, the voltage reaches a breakdown voltage before the upper and lower depletion layers, which spread in an N<-> epitaxially grown layer 2, link together. As a result, an abnormal phenomenon ceases from generating in the VCE-Ic (collector-emitter voltage-collector current) characteristics of the P-N-P Tr.
