Title: Connecting device, and manufacturing method therefor
Inventor: TANAKA TSUTOMU
IPC: E05D15/40
Filed: 1992-12-29
Abstract: PURPOSE:To materialize a connecting device that controls relative movement between bodies with stabilized force at low cost. CONSTITUTION:A first arm 21 is made of synthetic resin by molding as a unit, and a flange 27 with a diameter larger than that of its intermediate is provided to the front end of a pivot 26 that is provided in projection to the face 24a (projecting face) in a wider part of the arm. A second arm 30 is made of synthetic resin by molding as a unit by employing a forming die that utilizes the outer circumference of the pivot 26 and the projecting face 24a of the first arm 21 as a part for forming the face, and is connected to the first arm 21 so that it can swing freely, but can be checked in reverse motion. One end 30a of the second arm 30 is stuck firmly to the outer circumference of the pivot 26 and the projecting face 24a of the first arm 21. As the end 30a is pressed stringly against the outer circumference of the pivot 26 by construction produced after molding, stabilized and proper friction force is produced between the arms, and relative movement between bodies connected to holding holes 22 and 35 of both the arms respectively through fixing members 40 and 45 is controlled by stabilized friction force between the arms.

Title: Manufacture of laminated ceramic electronic component
Inventor: UEHARA TAKAYUKI
IPC: B28B11/02
Filed: 1991-12-27
Abstract: PURPOSE:To prevent delamination, a crack of a laminate by calendering a ceramic green sheet obtained by any of steps before the sheet is laminated at a temperature of a glass transition point or higher of binder resin. CONSTITUTION:Green sheets are so laminated as to form opposed inner electrodes by superposing the sheets by an electrode material paste coating film formed on the sheet, and press-bonded to manufacture a press-bonded laminate. The unburned press-bonded laminate cut into individual capacitor units and hence into chips is calendered at a temperature of glass transition point or higher of binder resin contained in the sheet. Thus, delamination, a crack of the laminate can be reduced.

IPC: G03G15/043
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To form a toner image having proper density even when the environment changes.

Title: Ignition timing controller of internal combustion engine
Inventor: TOYODA KATSUHIKO
IPC: F02P5/15
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent generation of knocking and improve fuel consumption by performing a lag control for an idle time basic ignition timing only when an intake temperature is a set temperature or more and engine load is set load or more. SOLUTION: A lag control is performed for idle time basic ignition timing by a control means 104 by an intake temperature and engine load or by correcting lag amount for the intake temperature by engine load only when the intake temperature is a set temperature or more and engine load is set load or more. By performing either one of the above controls, the lag control is not performed because knocking is not generated when engine load is small or light even if the intake temperature is high. Because lag amount can be properly controlled for engine load, proper lag amount according to generation frequency of knocking can be set. Thus, generation of knocking is prevented and deterioration of fuel consumption is prevented.

Title: Method for detecting collision in lan and terminal therefor
Inventor: IWAI MASASHI
IPC: H04L12/28
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To easily and accurately detect a transmission collision in a LAN which is made to branch off in terms of high-frequency. SOLUTION: In the LAN branched off in terms of high-frequency, a terminal 30 is equipped with a collision decision AC signal generation part 35 which generates an AC signal and a collision detection part 34 which detects a beat signal. Prior to data transmission, the collision decision AC signal generation parts 35 of each terminal 30 send out collision decision AC signals which have slightly different frequencies. The signals pass through each branching device 20 and are transmitted to all the terminals 30 because they are AC signals. The collision detecting part 34 of each terminal 30 amplifies the collision decision AC signal by using a non-linear amplifier. If another collision decision AC signal is superposed on the collision decision AC signal, a beat signal is generated in the output thereof. If the output is the beat signal, a transmission collision is decided.  Consequently, the transmission collision can easily and precisely be detected even in the LAN branched off in terms high-frequency.

Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To reduce torque pulsation of a magnet motor, by forming radial slits in a core so that the slits may be positioned in the middle of each adjacent permanent magnets in the peripheral direction. SOLUTION: In a core 6 of a rotor 2 of a magnet motor, radial slits 11a, 11b, 11c, and 11d are formed so that the slits 11a, 11b, 11c, and 11d may be positioned among permanent magnets 7a, 7b, 7c, and 7d. When electric currents are made to flow to the windings 5a, 5b, and 5c of a stator 1, a magnetic flux Φs is generated around the windings 5a, 5b, and 5c and by-passes the slit 11a having a high magnetic reluctance. The magnetic flux Φm generation from the permanent magnets 7a and 7b flows in the direction shown by the arrow. Therefore, the width of the torque pulsation of the magnet motor can be reduced, because the resultant magnetic flux distribution of the magnetic fluxes Φs and Φm in a gap 10 becomes smoother as compared with the conventional example.
