Title: Control circuit for demodulator
Inventor: NAWATA HIDE
IPC: H04L27/22
Filed: 1990-11-02
Abstract: PURPOSE:To surely lock the demodulator to a regular synchronizing frequency by making an acquisition range of an AFC circuit sufficiently narrower than a symbol rate in an asynchronizing state (including pseudo synchronization). CONSTITUTION:When an acquisition range switching signal 508 being an output of a discrimination section 7 is asynchronous, a selector 506 selects a position of 'small upper limit' and a selector 507 selects a position of 'small lower limit' respectively to allow an AFC acquisition range to be set to a sufficiently narrower range than a symbol rate. In this case, the demodulator causes pseudo synchronization but a sweep section 8 continues sweeping. When the frequency is transited, the AFC circuit 9 in operation within the narrow acquisition range cannot follow the frequency and the pseudo synchronization is unlocked. Then the demodulator locks with the regular synchronizing frequency and a discrimination section 7 discriminates the synchronization.

Title: Production of isopropylnaphthol
Inventor: TANAKA MICHIO
IPC: B01J27/232
Filed: 1988-11-25
Abstract: PURPOSE:To produce the subject compound with excellent productivity by oxidizing diisopropylnaphthalene with O2, separating the resultant diisopropylnaphtahlene monohydropheroxide from the starting raw material using a lower aliphatic alcohol and decomposing the separated compound with an acid. CONSTITUTION:Diisopropylnaphthalene is oxidized with molecular oxygen to provide diisopropylnaphthalene monohydroperoxide, which is then decomposed with an acid to afford isopropylnaphthol. In the process, the diisopropylnaphthalene monohydroperoxide is separated from the unreacted diisopropylnaphthalene which is the starting material using a 1-4C lower aliphatic alcohol and then used for the next step. The amount of the unreacted diisopropylnaphthalene carried into the acid decomposition step after the oxidization step can be reduced and the scale of the acid decomposition step can be reduced by the above-mentioned method. Thereby, productivity is improved and the method is industrially advantageous with high purity and selectivity. The resultant compound is useful as a raw material for synthetic resins fibers, medicines, agricultural chemicals, dyes, etc.

Title: Voice mail equipment
Inventor: HONMA TAKAYUKI
IPC: H04M3/50
Filed: 1986-12-15
Abstract: PURPOSE:To prevent erroneous detection of a disconnect signal due to coming- round of a reproduced voice signal by invalidating the output of a disconnect signal detector by a processor not to stop reading out a memory if data whose control bit is set to '1' is reproduced when a message is transmitted to a terminating subscriber. CONSTITUTION:When a message is spoken by a telephone T1, it is digitally converted and is successively written in a prescribed area of a memory 12 by a controller 20. A detector 18 monitors an input analog signal to input a signal S1 to a controller 20 and switches a control bit F added to data from '0' to '1'. When a telephone T2 in the terminating side requests message transmission, the controller 20 reads out the message in the memory 12 and converts it to an analog signal, and this signal is sent to the telephone T2 through an exchange EX or the like. The controller 20 monitors the control bit F; and if this bit F is '1', a processor 14 ignores detection of the disconnect signal though a detector 16 reports detection of the disconnect signal, and the controller 20 is not instructed to stop reading out the memory. Thus, erroneous detection of the disconnect signal due to cominground of the reproduced voice signal.

Title: Finder optical system
Inventor: MUKAI HIROSHI
IPC: G02B15/16
Filed: 1990-11-02
Abstract: PURPOSE:To achieve the high variable power ratio of a finder optical system by moving the positive lens groups of an object lens and a relay lens on an optical axis during variable power operation, and performing variable power through each of the object lens and the relay lens. CONSTITUTION:An object lens L0 consists of a negative lens group L1 on the object side and a positive lens group L2 on the eye side which moves as shown by arrow mark m0 in zooming from a Wideview-end to a Telescopic-end, while a relay lens LR moves as shown in arrow mark mR. As the object lens L0 moves into the state of being on the Telescopic-side, the plane of the object lens L0 moves to the object side. That is, the object lens L0 is given the condition of being short in total length and the relay lens LR also moves to the object side with the movement of the first plane I1 so that variable power can be achieved not only at the object lens L0 but also at the relay lens LR. It is thus possible to achieve high variable power ratio.

IPC: H04B1/38
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To specify the position of an alarm reporter and administer the entrance and existing of the alarm reporter with simple constitution. SOLUTION: An emergency alarm timer 1 decreases in its output level to '1', '1/2', and '1/4' when the alarm reporter operates an emergency button SW1 to send specific small-power radio signal RF to which an output level value is added by the stages. A transmitter receiver 3 receives the radio signal RF and sends the lowest output level value of the radio signal RF to a receiving center 5. The receiving center 5 fins the place of the emergency alarm timer 1 according to the said output level value. Further, an interrogator 6 sends interrogation signals from antennas 7, 7... installed at entrance and exits at all times and when the emergency alarm timer 1 automatically answers the interrogation signal, the exiting of the alarm reporter is transmitted to the receiving center 5.  Further, when the alarm reporter goes out, the emergency alarm timer 1 continues to send to specific small-power radio signal RF automatically at specific intervals of time, so the alarm reporter is traced in real time.

Title: Contactless measuring method of temperature of tunnel kiln
Inventor: MATSUSHITA ASUKA
IPC: G01J5/00
Filed: 1992-10-12
Abstract: PURPOSE:To measure the temperature of a baked object or the like accurately by processing a black body to the side wall of a sheath, detecting the luminance by a slit CCD camera, combining thermal images obtained through the slit and obtaining the total image of the baked object. CONSTITUTION:A CCD camera 6 is set to the outer face of a slit 5 of a narrow width formed in a kiln wall 1. The luminance and thermal images of a sheath 4 transferring a baked object 3 are continuously caught and detected. The temperature of the baked object 3 is measured by correcting the influences of the other reflecting light on the basis of the temperature data obtained from the CCD luminance of a point of a black body preliminarily processed at the side wall of the sheath 4. The shape and temperature distribution of the baked object 3 are measured in a manner whereby the strips of thermal images obtained through the slit 5 are combined in conformity with the moving speed of the sheath 4 and displayed in pseudo colors as a total image onto an ITV monitor. Therefore, if the temperature measuring mechanism is installed at each of a plurality of points in the longitudinal direction of a tunnel kiln, a highly reliable heat pattern within the furnace can be formed from the obtained temperature data.

Title: Optical element for diffraction and optical pickup device using the same
Inventor: HAYASHI KENICHI
IPC: G11B7/09
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To evade decrease in light utilization efficiency caused by unnecessary refraction with respect to an optical element for diffraction which is used to split laser light into three beams and irradiate the signal surface of a compact disk, etc., with them. SOLUTION: The laser light from a laser diode 21 of a CD pickup device 20 passes through the optical element 1 for diffraction and is split into three beams by a 1st polarizing diffraction grating 3 made of a birefringent material on its surface and passed through a 2nd polarizing diffraction grating 4 made of a birefringent material on the opposite-side surface to irradiate the disk 27 through a 1/4-wavelength plate 25. Return light from the disk 27 passes through the 1/4-wavelength plate 25 again to become linear polarized light having an orthogonal polarization direction and this light is made incident on the optical element 1 for diffraction.  Consequently, the light passes through the 1st polarizing diffraction grating 3 of the optical element 1 for diffraction and is only diffracted by the 2nd polarizing diffraction grating 4 and its primary diffracted light irradiates the photodetection surface of the photodiode 22. The laser light is not diffracted unnecessarily, so the decrease in light utilization efficiency can be evaded.
