Patent JP-H03258113-A (JP)
Title: Sawtooth wave generating circuit
Inventor: MINATO CHUICHI
IPC: H03K4/50
Filed: 1990-03-08
Abstract: PURPOSE:To obtain the output of a sawtooth wave whose falling period and DC voltage are constant by providing two comparators or more. CONSTITUTION:When a pulse is inputted to a pulse input terminal 2, it is fed to the base of a transistor(TR) 4 and the TR 4 is disconnected for a pulse period T1. When the voltage at a sawtooth wave output terminal is larger than the base voltage of a TR 19 of a comparator 38, a TR 20 is disconnected and a TR 8 is disconnected. Thus, the TR 7 is saturated. A reference power supply 34 is connected to the base of the TR 11 of the comparator 37 and the current of a constant current source 12 flows to the collector of the TR 11 by selecting the DC voltage to a proper value, inputted to a current mirror circuit 40 and outputted from the collectors of the TRs 14, 15. The current flows from the TR 14 to a resistor 29 and the base of the TR 9, which is saturated. The current of the TR 15 is inputted to a current mirror circuit 41, subject to mirror comparator by the TRs 30, 31 and outputted as the collector current of the TR 30. Thus, the sawtooth wave whose falling period and DC voltage are constant is generated independently of a pulse input period.

Title: Slip inspection system
Inventor: WADA TADAHIRO
IPC: G11B15/46
Filed: 1978-05-15
Abstract: PURPOSE: To accurately detect the slip quantity between a magnetic tape and a capstan by comparing the period of the capstan tacho pulses having been detected and the period of the data of a fixed density having been read.  
     CONSTITUTION: Tacho pulses of the period corresponding to the peripheral speed of a capstan are detected by a rotary disc 7 turning integrally with the capstan and a tacho pulse sensor 8 and the period of the tacho pulses is stored in a memory 22 via timing pulse generator 18, counter 19 and register 20. On the other hand, the data of a fixed density having been recorded in a magnetic tape 6 are read out by a read head 4 and the period of the data is stored in a memory 16 in a similar manner. The storage contents of these memories 16, 22 are read out in synchronization and are compared in a comparing arithmetic circuit 24. The circuit 24 in turns generates the differential signal of both inputs corresponding to the slip of the capstan and tape, whereby the accurate slip quantity is detected.

Title: Component mounting apparatus
Inventor: HIROSE YOSHITAKE
IPC: H05K13/04
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To provide a component mounting apparatus which prevents the vacuum chuck marks caused by strains, etc., from remaining on a substrate. SOLUTION: A support mechanism 1 has vacuum pads 3 projecting from the top surface of a stage 2. The pads 3 vacuum-chuck a cell 21 at their top faces and a backup block 5 supports a bottom face of the cell 21, corresponding to the vacuum chuck position of an electronic component 22. A vacuum chuck head 4 is lowered to depress the electronic component 22 provisionally compression-bonded into the cell 21 through an anisotropically conductive tape 23, thereby compression-bonding the component 22 onto the cell 21. The cell 21 is vacuum-chucked on the top face of each pad 3 composed of an elastic body projecting from the top face of the stage, and hence the each pad 3 is elastically deformed according to the pressing force exerted on the cell 21 from the head 4, thus allowing the inclination angle of the cell 21 to be adequately changed.

IPC: B41J29/48
Filed: 1990-03-08
Abstract: PURPOSE:To enable print data to be preserved and also prevention of failure such as breakage of a printing medium to ensure stable printing by providing a detector capable of detecting the presence of a printing sheet in a direction where a head fixing base runs, on said base. CONSTITUTION:A sensor for detecting the presence of a printing sheet and a sheet width uses a light reflection-type sensor 12 consisting of a photodiode and a phototransistor. Each sensor 12 detects periodically the presence of a printing sheet located at the far end in the running direction of a carriage, using a clock signal, and stores the presence of the sheet in a latch circuit 13. After that, CPU 14 reads an output Q from the latch circuit 13 into a 1/0 port during the operation of a printer. If CPU detects the presence of the sheet at the far end in the printing direction, it perform a process such as printing suspension, carriage stop or sheet jam warning. In addition, the CPU performs the control to prevent a failure such as the loss of print data or the breakage of a printing medium which is caused by continuation of the printing process under a state where printing the sheet is impossible.
