Title: Sound image localization device
Inventor: AZUMA IWAO
IPC: G10K15/12
Filed: 1990-05-08
Abstract: PURPOSE:To simulate the difference from listening depending on the direction and to obtain clear sound image localization by providing a processing circuit of a musical tone signal, a table storing a transfer data in each direction with respect to a listener and a readout means. CONSTITUTION:The transmission of a musical tone from a specific direction is simulated by varying a delay time of a delay circuit, a filter characteristic of a filter 20 and an amplification factor of an amplifier 21. That is, a sound from a sound source 12 close to the ear of the listener is delivered without almost a delay and attenuation and a change in its frequency characteristic, but a sound from a sound source 12 remote from the ear has a large delay time, attenuation and high frequency sound attenuation. The transmission data representing the characteristic is stored in advance in tables 13-15 and the data corresponding to the direction inputted from a localization designation means designating the direction of the musical tone is set to the delay circuit, the filter 20 and the amplifier 21 by reading the data by read means 16-18. Thus, the transmission characteristic in a direction from which the musical tone is listened is really simulated and the clear sense of sound localization is realized.

Title: Wheel cylinder for leading brake
Inventor: INOUE TAKASHI
IPC: F16D65/56
Filed: 1986-05-26
Abstract: PURPOSE:To prevent adjustment of shoe clearance, which follows the deformation of a brake drum, from becoming excessive, by providing an adjusting gear screwed in a piston put in a cylinder chamber and a sub-gear in a space connected to said cylinder chamber, said sub-gear meshing with said adjusting gear. CONSTITUTION:When a shoe clearance increases due to the wear of a brake shoe, a piston 2 moves to recover determined shoe clearance. After that, an adjusting gear 3 rotates to make said piston 2 move on a male screw 3a' because a sub-gear 10 is not rotatable due to a clutch spring 12, the movement causing the brake shoe to rub the drum to generate braking force. While, when said piston 2 moves forewards following the deformation of the drum in braking, the shaft 3a of said adjusting gear 3 can not rotate because the axial force to said shaft 3a is large, and so both gears 3 and 10 move forewards together, said sub-gear 10 compressing a cone spring 11. Due to the above construction, the adjustment of shoe clearance is prevented from becoming excessive.

Abstract: PURPOSE:To correct an optical mask pattern error by a method in which photoresist is applied on the optical mask forming surface, the photoresist is exposed to light from the opposite side and developed, and the mask pattern portions not protected by the resist are removed. CONSTITUTION:A processing error has caused patterns 2 and 3 to have unrequired portions 6 and 7. For correcting such error, photoresist 8 is applied and baked. The resist 8 is then exposed to beams having an exposure corresponding to the portions 6 and 7 and applied from the side opposite to the pattern forming side. By developing it, a resist pattern 8 in which the portions 6 and 7 are exposed is obtained. By selecting an appropriate exposure, a pattern with slopes can be obtained. The unrequired portions 6 and 7 are then removed by gas plasma of CCl4, for example, whereby a proper space 4 is defined. The pattern 8' is then removed to obtain a target optical mask.
