Title: Musical sound synthesizing device
Inventor: NAKAMURA SHIGEKAZU
IPC: G10H1/08
Filed: 1993-05-31
Abstract: PURPOSE:To emphasize a harmonic of fundamental frequency of a specific pitch by varying the delay time of one output terminal other than an output terminal which is set to the delay time corresponding to the specific pitch to a delay time different from the delay time corresponding to the specific pitch. CONSTITUTION:Assuming that a signal of one cycle of the pitch of a musical sound to be generated is inputted to a device 10, the input signal inputted to the device 10 is read out of TAP1 and TAP2 of a variable delay part 14 respectively and fed back to an adder 12 through multipliers 16 and 18. At this time, the read position of the TAP1 is fixed so as to obtain the delay time corresponding to the pitch to be sounded, so the fundamental frequency of the pitch to be sounded is emphasized. A harmonic which is an integral multiple of the pitch of the fundamental frequency, however, is included owing to the feedback, so the read position of the TAP2 is varied to vary the delay time of the read of the TPA2, and then a harmonic corresponding to the varied read position can be emphasized.

Title: Diagnostic apparatus for leakage in fuel evaporative gas purge system
Inventor: MAJIMA YOSHIHIRO
IPC: G01M3/26
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a diagnostic apparatus whose leakage diagnostic accuracy is enhanced by excluding an influence due to the consumption of a fuel. SOLUTION: When a leak is diagnosed, a fuel consumption amount between a first pressure measuring section and a second pressure measuring section is computed from a map or the like according to an average injection pulse, an average vehicle velocity, an average engine speed, an average intake air amount or the like. A pressure correction amount ΔP1b and a pressure correction amount ΔP2b are set according to the ratio of the fuel consumption amount to a fuel tank space volume. Then, a pressure change amount ΔP1 in the first pressure measuring section and a pressure change amount ΔP2 in the second pressure measuring section are corrected respectively by the pressure correction amount ΔP1b and the pressure correction amount ΔP2b (ΔP1=P1b-P1a+ΔP1b, ΔP2=P2b-P2a+ΔP2b).  Thereby, the pressure change amounts ΔP1, ΔP2 which exclude the influence of an increase in the fuel tank space area due to the consumption of a fuel and which are precise can be found. When the existence of a leakage in a purge system is diagnosed on the basis of the pressure change amounts ΔP1, ΔP2, also a very small leak which is hard to detect in conventional cases can be detected.

Abstract: PURPOSE:To automatically discharge especially a resist, etc., with high precision by carrying out a pumping action by electrical control in the title device for extracting a desired amt. of a liq. from a liq. storage part, pumping, and discharging the liq. CONSTITUTION:A driving motor 29 provided in a housing 17 is driven, and a lower member 16 is raised and closely attached to an upper member 15. The lower member 16 is then lowered by the driving motor 29 to expand a bellows 14 to the lower side.

Abstract: PURPOSE:To obtain a vertical output pulse of a constant pulse duration by dividing a stepped doubling clock input synchronizing with the horizontal synchronizing signal of a video signal to a frequency below a vertical frequency to raise the output pulse, at the same time, counting the constant number of the clock inputs and falling the output pulse. CONSTITUTION:When the video signal is inputted to an input terminal 1, the vertical synchronizing signal of the video signal is separated in a synchronizing separator circuit 2 and this vertical synchronizing signal is transferred to a reset circuit 3. This reset circuit 3 resets a frequency divider 5 having the input terminal 4 of the clock pulse synchronizing with the horizontal synchronizing signal of the video signal input by the vertical synchronizing signal. Herein, the frequency of the clock pulse is stepped doubling of the frequency of the horizontal synchronizing signal.
