Title: Production of floppy disk
Inventor: SATO KEIICHI
IPC: G11B23/033
Filed: 1994-12-02
Abstract: PURPOSE: To produce a magnetic disk for floppy disks. CONSTITUTION: The magnetic disk for floppy disks is produced by using a double coated tape having a thermosensitive tacky adhesive layer contg. a solid plasticizer, thermoplastic resin and tackifier on one surface of a base material and a pressure sensitive adhesive layer on another surface for adhesion of a center core and a magnetic sheet. Unnecessary objects, such as separators, are fewer than a conventional method of using the double coated tape. Since the pressure sensitive adhesive is applied only on one surface, the accuracy of blanking is high. The floppy disk having the durability equiv. to or better than the durability of commercially marked floppy disks, etc., is thus obtd.

Title: Structure for prime mover section for lawn mower
Inventor: SHIMAMURA TERUO
IPC: F01P5/06
Filed: 1988-11-29
Abstract: PURPOSE:To prevent floating dusts from combing in a cooling air inlet port by forming a blow-off port which is communicated with the exhaust air side of a radiator via a guiding air passage and sucks exhaust air downward out of the upper section of the cooling air inlet port at a bonnet. CONSTITUTION:A lawn mower has its prime mover section 4 arranged within a bonnet 3 at the rear section of its body. The circumferential wall of the bonnet 3 is formed with the cooling air inlet port 23 of an engine cooling radiator 15 within the prime mover section 4. In the aforesaid structure, a blow-off port 24 is formed, which is communicated with the exhaust air side of the radiator 15 via a guiding air passage R, and sucks cooling exhaust air downward out of the upper section of the inlet port 23. When floating dusts scattered from a mower at the front section of the body come close to the inlet port 23, the floating dusts are blown off downward by cooling exhaust air blown out of the blown-off port 24, this constitution can thereby prevent floating dusts from coming in the bonnet 3 out of the inlet port 23.

Title: Signal processing circuit
Inventor: TOYOSHIMA SATOSHI
IPC: H04N5/208
Filed: 1992-10-14
Abstract: PURPOSE:To obtain a prescribed horizontal contour correction quantity at all times even when the aspect ratio is converted by controlling the horizontal contour correction quantity in response to a switching signal. CONSTITUTION:An amplification factor of an amplifier circuit 24 in a horizontal contour correction circuit 2a is controlled by an aspect ratio switching signal. The amplification factor of the amplifier circuit 24 is changed in response to the aspect ratio switching signal so as to make the correction quantity constant even when the aspect ratio is switched. The correction quantity of a correction signal V3 has a relation of DELTAVa>DELTAVb similarly to a conventional circuit with respect to switching signals H, L. Since the amplification factor of the amplifier circuit 24 for the switching signal L is controlled smaller than the case with the switching signal H, the correction quantity after amplification has a relation of DELTAVa2=DELTAVb2 and the correction quantity at an output Vout of an adder circuit 23 is equal as DELTAVa3=DELTAVb3.

Title: Composite type printer
Inventor: OSAWA TERUKAZU
IPC: B41C1/00
Filed: 1987-11-30
Abstract: PURPOSE:To enable the title printer to be simply used by copy sensation, to obtain final printed matter of high quality, and to improve operating efficiency remarkably, by establishing a plate detecting structure that a plate is so structured as to stop by being pinched by specific positions of a fifth and a sixth delivery means. CONSTITUTION:A photosensitive material is pinched between a fifth and a sixth carry rolls 45, 47 and is stopped at a position where a plate is easily detected. Thereafter, a plate detection stand 39 and a plate detecting mechanism 34 are drawn out this side as they are, and the plate detecting mechanism is sidely brought down on the plate inspection table 39 by using a support rod 46 of the plate inspecting mechanism 34 as an axis. Then, since an image face is upward when brought down, the image face can be inspected and corrected as it is. After ending plate inspection and correction, the plate inspecting mechanism 34 and the plate inspection stand 39 is returned to the original state, and the inspected photosensitive material is sent to a printer side. For automation, detection with a detection sensor at a top part is neglected, and the photosensitive material is carried as it is to a paper feed roller of the printer. Therefore, this printer can be used with copy sensation by everyone, and final printing of high quality can be obtained. By integration of an engraving machine and the printer, operating efficiency can be remarkably improved.

Title: Electrostatic sensor apparatus
Inventor: MASUDA NOBORU
IPC: G01N27/22
Filed: 1991-11-18
Abstract: PURPOSE:To improve the degree of freedom for installation and the stability of the title apparatus so as to reduce its size by adopting a radio transmission route consisting of radiation means and wave-receiving means to send a drive reference frequency signals to a ceramic resonance means. CONSTITUTION:A radiator 2 radiates reference frequency signals, while wave receiving apparatuses 3a-3c receive the radiated reference frequency signals. High-frequency amplifiers 4a-4c amplify the radiated reference frequency signals into the drive reference frequency signals, and since respective ceramic resonators 5a-5c output the signals with any amplitude corresponding to the drive reference frequency signals based on each resonance characteristics, the amplitude of each signal may vary accompanied with the change of respective resonance characteristics. Detectors 8a-8c extract the changes of signal amplitude and output the electrostatic capacity detection signal consequently. The drive reference frequency signals are supplied for the ceramic resonance means by means of radio wave, so that the degree of freedom for installation can be improved, and furthermore the stability can be also improved because the characteristic change of one channel gives no influence on oscillation means or other channels. The ceramic resonance means is adopted so as to reduce the size as well.
