Inventor: SHIBUYA MASATOSHI
IPC: H04R3/00
Filed: 1994-06-27
Abstract: PURPOSE:To prevent a vehicle outside alarm sound or the like from becoming hard to be heard due to a vehicle inside alarm signal, in the case of a vehicle reverse alarm device that calls attention to persons inside the vehicle and at the rear part of the vehicle outside when the vehicle reverses (backs). CONSTITUTION:When it is detected that a back gear has been entered, a voice alarm signal and a leading sound to draw attention to vehicle reverse are generated by predetermined frequency in regard to vehicle outside and vehicle inside speakers 41, 42, and after this, preferably, if the vehicle speed indicates the state of stop, the voice alarm signal is outputted only from the vehicle outside speaker 41 without being outputted from the vehicle inside speaker 42, although the leading sound is outputted from the vehicle outside and inside speakers 41 42.

Title: Power amplifier
Inventor: MARUYAMA TAKASHI
IPC: H03G3/30
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To confirm accurately the operation even when a signal waveform in the case of the operation confirmation test differs from that in the case of actual use by using an output of an input signal detector of the power amplifier for a reference input of an amplification factor control circuit of the power amplifier. SOLUTION: An input power Pin from a signal source 1 is amplified by a gain control circuit 10, power-amplified by a power amplifier circuit 11 to be a power Pout and it is outputted to a load 2. An input signal detector 12 couples with a small part of the input power Pin to detect it and to produce a DC voltage e1=k1×Pin. An output signal detector 13 couples with a very small part of output power to detect it and to produce a DC voltage e2=k2×Pout. A differential amplifier 14 amplifies a difference between the voltages e1, e2 by using the e1 as a reference to control a gain control circuit 10, that is, conducts feedback control so that a relation of e2=e1 is obtained. Thus, the gain G of the power amplifier 2 is expressed as G=Pout/Pin=k1/k2.  The coefficients k1, k2 of the detectors 12, 13 are stable against a temperature change and a secular change or the like and then accurate control is conducted. It is not required to conduct special control to confirm the operation of products.

Title: Production of steel sheet panel excellent in tensile rigidity
Inventor: SUGIURA NATSUKO
IPC: C21D8/02
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To improve the tensile rigidity of a steel sheet by using a steel sheet applied with prestrains of a specified amt., furthermore subjected to heat treatment, thereafter subjected to a tension test in the L direction once more, and in which the ratio of the gradient of a stress strain curve by a specified strain amt. to the Young's modulus lies in a specified range. SOLUTION: In a panel using a material in which, at the time of executing a tensile test after the application of prestrains of 2% equivalent to pressing, the relation of X/Y>0.8 is held up to 0.06% strain amt. in the case the instantaneous Young's modulus is defined as X (equivalent to a gradient of a stress- strain curve), and the Young's modulus is defied as Y, tensile rigidity remarkably improves. In the steel, for suppressing the movement of movable dislocations and suppressing the reduction of the instantaneous Young's modulus, the segregation of interstitial solid solution elements such as C and N around the movable dislocations by heat treatment after forming is effective. For this purpose, the total content of the solid solution C and N is preferably regulated to, by weight, 0.0005 to 0.005%. Moreover, the heat treatment is executed preferably at 150 to 250 deg.C for 5 to 40 min.
