Title: Sound reproduction device
Inventor: SAWAI TOSHIHITO
IPC: B60R11/02
Filed: 1993-07-28
Abstract: PURPOSE:To listen to an excellent reproduction sound even under a noisy environment by detecting a noise level and compressing the dynamic range of the reproduction sound corresponding to the noise level. CONSTITUTION:Analog audio input signals from a radio and a cassette tape, etc., are converted to the reproduction sound and outputted inside an automobile compartment with noise through an A/D converter 1, a digital signal processor(DSP) 2, a D/A converter 3 and a speaker 8, etc. The noise level in the automobile compartment is detected by a microphone 7 and supplied through the A/D converter 6 and the DSP 2 compresses the dynamic range of the reproduction sound in real time corresponding to the noise level. Thus, the small sound of a low level area becomes large and can be listened to without receiving the influence of masking by the noise. On the other hand, the large sound of a high level area does not become larger than needed and can be listened to as the improved sound without distortion and the excellent reproduction sound can be listened to even under the noisy environment.

Filed: 1995-06-30
Abstract: PURPOSE: To provide a liquid crystal display element which is decreased in the variations of a visual field angle characteristic and has an excellent display grade and a wide visual field angle. CONSTITUTION: Upper layer electrodes 35 are partly removed by etching, etc., and apertures part 38 are formed on the flat surface of an overcoating layer 34. Since the film thickness of the upper layer electrodes 35 on the flat surface of the overcoating layer 34 is uniform, the etching rate in the case the apertures part 38 are formed is constant in any places of the apertures part 38. Then, the overetching of the upper layer electrodes 35 does not arise and the upper layer electrodes 35 and the apertures part 38 are constituted of always the prescribed area. The variations in the visual field characteristics of the liquid crystal display element are decreased. Oriented films are subjected to orientation treatment in the direction parallel with the long side of the apertures part 38, by which the discontinuity of the orientation of the liquid crystals in the boundary parts between the upper layer electrodes 35 and the apertures part 38 is relieved and the liquid crystal display element having the excellent display grade is embodied.

Title: Lamp
Inventor: RONARUDO EE RESHII
IPC: H05B41/24
Filed: 1993-06-30
Abstract: PURPOSE: To reduce a voltage or current stress applied to a transistor switch so as to make a load waveform preferable by providing a current limiting network with a high-frequency trap and an impedance converting network. CONSTITUTION: A switch circuit 204 is provided with a transistor (Tr ) 210, wherein a gate is connected to an output of an oscillator 2O2; a source, to a circuit common line; and a drain, to a trap 120 via a line 140. The trap 120 is resonated at a frequency slight higher than a third harmonic frequency, so that a high voltage peak is decreased by changing a voltage waveform on the drain of the transistor 210 from a semi-sinusoidal pulse having an essentially incidental high peak value to a composite waveform composed of a basic wave reduced a third harmonic wave depending on a phase. The trap 120 reduces a harmonic wave on an input side to a network 122. Since an input voltage waveform of the network 122 becomes a sinusoidal wave, a waveform of a load becomes preferable, thus suppressing a harmonic wave power loss of a network element so as to achieve efficiency.

Title: Tape loading detector
Inventor: MIROKU NOBUYUKI
IPC: G11B15/665
Filed: 1988-07-27
Abstract: PURPOSE:To prevent a magnetic tape from being damaged by judging the loading state of the magnetic tape by utilizing the output signal difference of light by providing a light emitting element and a light receiving element at a tape guide positioned in the inside of the aperture of a cassette font plane by utilizing the surface of a cylinder having a mirror plane. CONSTITUTION:The light emitting element 12 provided at the tape guide 8 being positioned in the inside of the aperture of the cassette front plane emits irradiating light 14. The irradiating light 14 is reflected on the surface of the cylinder 1 having the mirror plane in a state where no magnetic tape 2 is loaded, and reflected light 15 is inputted to and received at the light receiving element 13. Since the irradiating light 14 is blocked by the magnetic tape 2 when the magnetic tape 2 is loaded, no reflected light 15 is inputted to the light receiving element 13. Since it is possible to detect whether or not the magnetic tape 2 is loaded at a normal position by utilizing the difference of the output signals of the light receiving element 13, the hitching or the stranding of the magnetic tape 2 at the time of loading can be detected in advance, which prevents the magnetic tape 2 or the cylinder 1 from being damaged.
