IPC: G10H1/34
Filed: 1993-12-10
Abstract: PURPOSE:To reduce power consumption without degrading scanning performance while detecting the motions of the keys and the pedals of a keyboard musical instrument by optical switches. CONSTITUTION:The optical switch of each key of an electronic piano consists of two phototransistors and two LEDs. These phototransistors and LEDs equivalent to eight keys are made into one block and eleven blocks each of PB1 to PB11 and LB1 to LB11 are provided. PB1 to PB11 are respectively connected to operation signal output lines T1 to T11 and as T1 to T11 are successively made into high levels, the light receiving conditions are scanned. On the other hand, each of LB1 to LB11 is connected to four operation signal lines, i.e., LB1 is connected to T9, T10, T11 and T1 and LB2 is connected to T10, T11, T1 and T2 and so on. Thus, for example, LB1 is turned on three timings prior to the time at which PB1 is put into a scanning timing and LB1 is turned off when the scanning is completed.

Title: Dielectric multilayer film mirror
Inventor: OBAYASHI YASUSHI
IPC: H01S3/10
Filed: 1986-12-27
Abstract: PURPOSE:To obtain required reflection band width by setting up the reflection factor of a multilayer film as a multivariable function expressed by the film thickness values of respective dielectric layers and determining the film thickness values of respective dielectric layers so that the difference between the function and the reflection factor of an objective wavelength is minimized. CONSTITUTION:A multilayer film mirror 5 is formed by alternately superposing dielectric films 61, 63... with a high refractive index nH and dielectric films 62, 64... with a low refractive index nL. The film thickness 61, 62... are respectively different and is not fixed. When the reflection factor Rlambda of the mirror 5 is defined as the multivariable function of the film thickness x1-xn of the films 61-6n, an equation I can be obtained. An equation II is obtained by specifying a reflection factor rlambda in each wavelength as objective spectral characteristics. In the equation II, a minimum value is substituted for the function F so that the difference between the multivariable function and the reflection factor of the objective wavelength is minimized to calculate the film thickness values x1-xn. Consequently, film constitution having the objective reflection factor characteristics can be obtained.

Filed: 1994-12-16
Abstract: PURPOSE: To obtain a differential-pressure transmission apparatus in which a transmission-part side is separated easily from a pressure-receiving-part side in a maintenance and inspection operation or the like by a method wherein a bolt hole is made in an insertion support base which is installed so as to suspend a differential-pressure transmission part and the differential- pressure transmission part is driven so as to be taken in and out by making use of the bolt hole as a guide hole. CONSTITUTION: In an insertion support base 33 which is installed so as to suspend a differential-pressure transmission part 32, two through holes 2 in which a female screw has been cut are made, on a transmission-part side 1, bolts 3 are inserted into and passed through, and they are tightened by a tool such as a screwdriver or the like. Tip parts 10 of the bolts 3 hit a cylinder part 11 on a pressure-receiving-part side 4. When the bolts 3 are tightened further, the transmission-part side 1 is pushed up. The bolts 3 are used to separate the transmission-part side 1 from the pressure-receiving-part side 4 in a maintenance and inspection operation or the like, and they are removed usually. Consequently, while a pressure and differential-pressure transmission apparatus is operated, the through holes 2 in which the female screw has been cut act to promote heat conduction.  When the inside of the transmission-part side 1 generates a temperature difference partly due to a cause from the outside of the transmission-part side 1, the temperature of an amplifier 15 at the inside can be made uniform in a short time by the through holes 2.

Title: Voltage detecting circuit
Inventor: YAMADA ICHIRO
IPC: G01R19/00
Filed: 1989-12-01
Abstract: PURPOSE:To enable an accurate voltage detection with low power consumption by providing a 1st voltage detecting circuit and a 2nd voltage detection circuit the operation of which is controlled by the result of 1st voltage detection. CONSTITUTION:At first, a back electromotive voltage amplified with a chopper is detected by an inverter 201. At this stage, a decision level to detect a rotation is defined to -1.2V under making VDD=0V, and a logic level of the inverter 201 becomes to 1/2(VDD-VSS) 0.75V. When the back electromotive voltage is less than -0.75V, the output of a SR latch 203 is not inverted and a comparator 202 does not work accordingly. When the back electromotive voltage is closer to VSS than -0.75V, the output of SR latch 203 is inverted to become low level and the comparator 202 is worked. Thus, only the inverter 201 is worked when the back electromotive voltage is far different from -1.2V which is the original detection level, and the accurate detecting operation is made when the voltage is close to -1.2V which is the original detection level, thereby the voltage detection with high accuracy can be attained.
