Title: Digital signal receiver
Inventor: FUJIYAMA TADATAKA
IPC: H04L7/033
Filed: 1988-09-20
Abstract: PURPOSE:To supply a reference signal corresponding to an input digital signal to a PLL by using a table clock signal and discriminating a sampling frequency from a preamble of the input digital signal to form the reference signal. CONSTITUTION:The length of a maximum inversion interval is measured by a stable clock signal CK1 generated from a clock generating circuit 18, a sampling frequency Fs is discriminated to form detection signals S1 and S2. A window generating circuit 4 generates a signal at (Fs=48kHz or 44.1kHz) and a signal at (Fs=32kHz) from a stable clock CK1, one of the signals is selected by the detection signals S1 and S2 and becomes a reference signal RE1. A window generating circuit 5 generates a reference signal RE2 from an output signal CK2 of a PLL 7. Thus, no accuracy is deteriorated alike the time constant of a monostable multivibrator. Moreover, since no monostable multivibrator is employed, the receiver is suitable for circuit integration.

Title: Optical recording system
Inventor: INOUE AKIRA
IPC: G11B11/105
Filed: 1985-10-22
Abstract: PURPOSE:To attain a recording by a low power laser light source by using a magnetic thin film transparent optically and having magnetization in a planer direction as a recording medium of an optical recording material including a waveguide. CONSTITUTION:At first, the magnetic thin film 3 is magnetized in a direction within the film face. In applying light passing through 2-dimensional information 6, that is, object light 5 and light passing through the waveguide 2 that is, reference light 7 to the said film 3, an interference fringe is formed on the film 3. Since the light is absorbed in the film 3, the film 3 has a temperature distribution corresponding to the interference fringe and the magnetization is lost at a part on the film 3 where the temperature exceeds the Curie temperature. An external magnetic field 4 reverse to the magnetizing direction of the film 3 is applied externally to stop the irradiation by the object light 5 and the reference light 7, the temperature of the film 3 is lowered and the magnetization of the part at the Curie point or over is reversed and the magnetization pattern corresponding to the interference fringe is recorded on the film 3. Thus, the information is recorded.

Title: Portable timepiece with stand
Inventor: YAMAMOTO SHIGERU
IPC: G04B37/14
Filed: 1984-11-08
Abstract: PURPOSE:To prevent the structure engaged with a middle from looking even in such a state that a stand is opened, by deviating the pin insert hole of the middle from that of the stand and assembling a pin so as to connect both holes. CONSTITUTION:A middle 1 is connected to a stand 2 by two pins 3. The pin insert hole of the middle 1 is deviated from that of the stand 2 while the pin insert hole of the stand 2 is inclined at a certain angle so as to assemble the pins 3 in the pin insert hole of the stand 2 from the outside thereof. When the stand 2 is opened gradually from this closed state, there is a click when the corner part 4 of the stand 2 is passed over and, when the stand is further opened, the state shown by the drawing is obtained. Because the holes are eccentric even in this state, repulsive force acts on the pins and the middle 1 and the stand 2 are fixed.

Title: Remote controller for video tape recorder
Inventor: SHINDO TAKESHI
IPC: H04N5/7826
Filed: 1987-09-19
Abstract: PURPOSE:To suppress power consumption of a battery and to extend the life of the battery by closing a power supply line from the battery to a sound reception part only during a normal reproduction and picture recording when the sound reception part is required to operate. CONSTITUTION:A code operating signal is outputted from a microcomputer 11, converted to a radio signal by a conversion part 14, then transmitted, and received by a reception part on the video tape recorder-side. At such a time, when a normal reproduction key is operated, a switch part 15 is continuously turned on by a switch control signal from the microcomputer 11, but when a recording key is operated, the switch part 15 is turned on for a prescribed time by a switch control signal from the microcomputer 11. Accordingly, only during a time of normal reproduction and picture recording when the sound reception part 8 needs the operate, the power supply line from the battery 1 to the part 8 is closed, and at times other than said time when the part 8 is not needed to operate, said supply line is opened. As a result, the consumption of the battery 1 can be suppressed, hence the life of the battery 1 can be extended.

Title: Lead frame
Inventor: YASUHARA MASANORI
IPC: H01L23/50
Filed: 1988-09-20
Abstract: PURPOSE:To improve the adhesive properties of the rear of a die pad and an epoxy resin, and to prevent occurrence of cracks due to the moisture absorption of the resin by forming a film composed of Si or an Si compound onto the rear of the die pad of a lead frame on which a semiconductor device is mounted. CONSTITUTION:The die pad of a lead frame 3 and an epoxy resin 2 are brought into contact through an Si oxide film 4 as an Si compound. Consequently, Si fillers contained in the epoxy resin and the Si film on the rear of the lead frame are stuck fast, thus improving the adhesive properties of the die pad and the epoxy resin. A quite the same effect is acquired even when a film including polycrystalline Si and Si such as an Si chip is shaped. The formation of such films is varied according to the material of the lead frame and the films formed through a sputtering method, a spin coating method, etc. As a result, since adhesive properties are enhanced, moisture is not collected under the die pad even when the epoxy resin absorbs moisture, thus preventing the cracking of the molding resin.

Abstract: PURPOSE:To read information such as an address signal of a recording track even in the recording mode by reducing the amplification factor of a preamplifier, which amplifies a detection signal from a photodetector, at a recording time. CONSTITUTION:The start address and the end address of recording are designated from an external device. A controller 23 sends a mode signal beta for a reproducing mode to a preamplifier 20, and the reproduced signal from a photodetector 9 is amplified with a high amplification factor by the preamplifier 20 to obtain the reproduced signal. An LPF21 permits only address signal components to pass through, and an address detecting circuit 14 reads them and sends them to the controller 23, and an optical head part B is moved to a track having the start address through a transporting system 12. The controller 23 sends a control signal alpha for switching to the recording mode, and the amplification factor of the preamplifier 20 is reduced by the signal beta. A semiconductor laser 3 is driven by the output corresponding to the control signal alpha to perform recording. The reflected light is received by the photodetector 9, and the reproduced signal passes the preamplifier 20 and the LPF21, and address signals are read by the address detecting circuit 14.

Abstract: PURPOSE:To prevent the generation of a bird beak, to fine an element easily and to flatten the surface of a device by forming an oxidizable mask film onto an Si substrate, etching the mask film and oxidizing the Si substrate and the mask film. CONSTITUTION:An SiC film 2 is shaped onto the surface of an Si substrate 1, and Si stepped sections such as trenches 3a, 3b for forming SiO2 layers in specified sections are shaped through etching such as anisotropic etching (isotropic etching may also be used). The SiO2 layer 4 is formed through oxidation. The SiO2 layer 4 is shaped into the trenches 3a, 3b and onto the top face of the Si substrate 1. When only the thin SiO2 films 4 formed onto the top face of the Si substrate 1 are removed, SiO2 films 4a, 4b are left only in the trenches 3a, 3b. Si stepped sections A and the film thickness of the SiC film 2 are determined in consideration of the rates of oxidation of the Si substrate 1 and the SiC film 2. Accordingly, the surface of a device after oxidation is flattened.

Title: Distortion compensator
Inventor: TAKAHASHI HIROAKI
IPC: H04B1/707
Filed: 1992-09-04
Abstract: PURPOSE:To provide the distortion compensator which prevents large noise even when a pilot signal is remained by using the pilot signal to which spread spectrum modulation is performed, can correctly detect the pilot signal even when an input signal is a multi-wave signal and higher-order mutual modulation distortion is overlapped with the pilot signal, and does not newly require any band for the pilot signal. CONSTITUTION:A pilot signal generator 21A generates the first pilot signal. The first pilot signal is added to a high frequency input signal just before or behind a first amplifier 12 after subjecting the signal to spread spectrum modulation by a spread modulator 22A. In this case, when the characteristic of the first amplifier 12 or a second amplifier 16 is fluctuated, both of mutual modulation components are not canceled each other bu the mutual modulation distortion component is remained. Therefore, a vector adjuster 23A adjusts the mutual modulation distortion component or the amplitude and phase of the first pilot signal to pass here, and the remained component of the first pilot signal detected by a pilot signal detector 25A becomes '0'.
