Filed: 1993-09-01
Abstract: PURPOSE:To suppress increasing of weight of a chain cover, effectively improve its rigidity, and prevent occurrence of film oscillation by forming a reinforcing rib which is projected to an inner space of a chain chamber along an outer periphery of a cam sproket of a chain cover. CONSTITUTION:A chain cover forms a chain chamber for circulation of a chain on a front side of an engine block of a V-type engine. In such a structure, a connection flange 35 in respect to a rear chain cover 5 is formed on a peripheral edge of a front chain cover 6 provided so as to cover a front side of the rear chain cover 5. In this case, a reinforcing rib 36 is provided on the front chain cover 6, which rib 36 is bent along an outer periphery of a first intake cam sproket, and projected to the inner space of the chain chamber. An expansion part 39 is formed on the front chain cover 6, which expansion part 39 has a portion opposite to the first cam sproket and expanded to the outer side of the chain chamber. It is thus possible to improve rigidity of the chain cover and prevent occurrence of film oscillation.

Title: Electron bema generating device
Inventor: KAI MIKIAKI
IPC: H01J37/248
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To prevent emitter destruction from occurring, even if an error is made in controll setting of a voltage to an electrostatic lens equipped between an emitter and an acceleration electrode. SOLUTION: A voltage applied to a lower electrode 6 controls a signal to a gate of a gate transistor GTb of a second CTC (Cockcroft=Walton) 9', and adjusts and sets a voltage from a power supply Vb. This adjusted voltage presents itself on the output side of the gate transistor GTb of the said second CWC 9', being boosted appropriately by the use of an excitation transformer TRb and a boser/rectifier circuit URb, and is applied to the lower electrode 6. This adjusted voltage also serves as a collector voltage of a gate transistor GTa of a first CTC 8' of an upper electrode 5. Accordingly, a voltage applied to the upper electrode 5 is set by adjusting the above-mentioned collector voltage by controlling a signal to the gate of the said gate transistor GTb, and therefore the said adjusted voltage does not exceed this collector voltage.

Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To apply a surface cover material having long bristles to a seat using an adhesive by coating a cushion pad with the adhesive, afterwards, covering and temporarily assembling the surface cover material, placing this temporary assembly on an arranging die and heating it with a heating die in which a foamed material having an open cell structure is put later. SOLUTION: A cushion pad P is formed in the shape of hollow bag of which the lower end side is opened, and the front side of this pad P is uniformly coated with an dissolved hot melt adhesive A by a dedicated spray gun through an adhesive applying process. Then, after the adhesive A is applied, a surface cover material H is overlaid but since this adhesive A is cooled and solidified just after application, even when the surface cover material H is overlaid, the surface cover material H and the cushion pad P are not immediately bonded so that the arrangement, etc., of the surface cover material H can be suitably adjusted. Afterwards, heating and pressurizing processes are executed.  Namely, an object temporarily assembling the surface cover material H and the cushion pad P is arranged on an arranging die 20, heated from the side of the surface cover material H by a heating die 30 and pressurized.

Title: Timing circuit
Inventor: SAITO HIROKI
IPC: G06F1/06
Filed: 1988-08-31
Abstract: PURPOSE:To decrease the draw-around frequency of a wiring and to extremely improve the working frequency by using the same element to form a frequency divider and a shift-register and realizing each function with switch of input systems. CONSTITUTION:When a 1st input system is selected by a selection signal SEL, the 1st and 2nd latch circuits consisting of NOR gates 6 and 7 as well as 11 and 12 and the shift registers connected to both latch circuits are operated as the delay circuits having the prescribed number of stages. The outputs of these delay circuits are fed back to the 1st input system and therefore the function of a frequency divider is secured with the frequency division ratios set in response to the number of stages. While a 2nd input system is selected by the signal SEL and the outputs of both latch circuits and the shift register are taken out. Thus the function of the shift register is ensured to output the data inputted in series to the 2nd input series in parallel with each other. The component elements can be shared between the frequency divider and the shift register. In addition, the 1st and 2nd latch circuits shares the first stage of the shift register. As a result, the number of circuit elements can be extremely decreased together with reduction of the draw-round frequency of a wiring set between blocks, and the working frequency is satisfactorily improved.

Title: Information processor
Inventor: KARASAKI SADAJI
IPC: G06F9/38
Filed: 1985-10-02
Abstract: PURPOSE:To increase the executing speed of a microprogram by producing a microaddress with the output of an instruction decoder to perform the processing of an additional mechanism instruction or the exceptional processing of an instruction. CONSTITUTION:An additional mechanism 8 if not connected yet is connected to a power supply via a pull-up resistance 14. Thus an H level of the signal voltage is applied to an instruction decoder 7 as an additional mechanism connec tion signal 15. While an L level of the signal voltage is applied to the decoder 7 as the signal 15 if the mechanism 8 is connected. As a result, the decoder 7 produces a microprogram address for execution of an instruction with connec tion of the mechanism 8 and then another microprogram address for exceptional processing of an instruction with no connection of the mechanism 8 respectively. In such a way, a test step for connection state of the mechanism 8 can be omitted. This increases the executing speed of a microprogram.

Abstract: PURPOSE:To temporarily fix an electronic part without damaging a printed board by attaching a temporary fixing member, which generates dynamic resistance between the inner face of a through hole and the fixing member, to a lead of an electronic part. CONSTITUTION:A soldered terminal is composed of a lead 6 and a temporary fixing part attached to a lead 6. The temporary fixing part is composed of two notched rings 7 and a wire 8 connected with the notched rings 7.

To temporality fix an electronic part in a printed board 4, the soldered terminal 1 is inserted into a through hole 5 of the printed board 4. The wire 8 is deformed and is brought into contact with the inner face of the through hole 5 with pressure. Since the wire 8 is pressed and comes in touch with the through hole 5, dynamic resistance is generated between the inside face of the through hole 5 and the temporarily fixing part. Due to the resistance, the electronic part is temporarily fixed in the printed board 4.
